ShoreTel Connect CLOUD Goes Way Beyond VoIP

By: John Shepler

VoIP phone systems are often seen as a one for one replacement for traditional analog business phones combined with Key Telephone and PBX systems. Reasons to make the switch to newer technology include removing the need for separate telephone and computer networks and the option to outsource the in-house switching system to the cloud. In fact, switching to IP phones opens the door to a much richer set of features, now commonly referred to as Unified Communications (UC).

ShorTel has been a leader in enterprise communications. ShorTel phones are common in companies large and small. ShorTel is also a leader in UC, with its ShorTel Connect CLOUD service. Here is a brief overview:


It’s important to emphasize that ShorTel Connect CLOUD is a fully hosted and managed communications solution that takes the monkey of telephone system management off your back, while adding new capabilities. These include Instant Messaging, video, desktop sharing, and conference calling.

In addition, you can integrate Customer Relationship Management (CRM) applications such as Salesforce and NetSuite to improve employee productivity. Automation is a key ability that’s offered by Unified Communications and presents a strong argument for upgrading from traditional telephony-only analog and VoIP systems.

Cloud-based UC offers some other efficiency advantages. First, you trade capital expenditures for pay-as-you-go monthly billing on a per-seat basis. At first glance, this might seem like six of one / half dozen of another. That is, until the need to scale up or down appears. Add more employees? Just add more seats to your existing system. No need to go out and make a major capital investment in a new PBX mainframe. Business in a downturn? Just reduce the amount of resources to match your resized organization.

These are the same arguments used for cloud computing, and for a good reason. Conceptually, the cloud works the same regardless of what application is hosted. Is voice just another app on cloud? Yes, with the caveat that real time streams such as audio and video require special prioritization to ensure quality of service.

Reliability and security are other major concerns with cloud-based systems. ShorTel offers enterprise-grade performance backed by strong Service Level Agreements (SLAs). Easy access to customer service is also provided as a managed system.

Are you feeling limited by your business telephone system and concerned that you are missing out on the productivity enhancements and cost savings offered by cloud-hosted Unified Communications systems? Find out what ShoreTel Connected CLOUD can offer you.

Many Flavors of Business Internet

By: John Shepler

You need to connect your business to the Internet. In fact, it’s almost impossible to do business now without a broadband Internet connection. Your customers, your cloud services, your emergency backup, your suppliers and perhaps the connection to your home office, remote sites or franchisees are all via the Internet. The only question is how to best achieve that connectivity.

Most businesses don’t have a lack of options for getting Internet service. What they have is a confusing situation with may different services offering different characteristics at different price points. Choosing the lowest price option may result in frustration when the connection can’t support your particular business activities. Automatically picking the highest priced option can increase your internet costs significantly and may also not provide the connectivity you need. Let’s see if we add some clarity to this decidedly unclear situation.

Business Internet options generally fall within two categories. The first are telecom services, usually regulated and tariffed. These were the first connections invented and adopted by business as well as the carriers themselves. The other category includes information services that are were primarily designed to serve the consumer market but now available for businesses too.

Telecom services include familiar names such as T1 lines, DS3, SONET fiber optic services and the newer Ethernet over Copper and Ethernet over Fiber connections. These are almost always intended for commercial and large organizational use. Most carriers won’t even provision these services to residences. That’s seldom a problem, because these telecom services range from several times to an order of magnitude higher in price than what residential users are used to spending.

What do you get for your telecom dollar? These services almost always offer symmetrical, dedicated bandwidth with a service level agreement (SLA). The service level agreement specifies the technical characteristics of your line service, the expected availability and how fast problems get attention and repaired. It’s a type of guarantee that you’ll get top rate performance.

Dedicated bandwidth means that you have exclusive use of the bandwidth you are paying for. You have access to a certain number of Mbps or Gbps on a 24/7 basis. You can run traffic occasionally or load up the line to full capacity continuously. The price is the same. It’s your bandwidth and nobody else gets access.

Symmetrical means that you get the same bandwidth in both the upload (transmit) and download (receive) directions. This isn’t important if you are just browsing websites, but it can be critical if you are running a server, backing up files to a remote data center, using cloud computing services, video conferencing or VoIP telephone.

Consumer oriented services are also referred to as “information services.” This is intended to imply that they are not a guaranteed telecom service and offered on a more casual basis. That basis means “best effort” delivery. The providers will make a good faith effort to ensure that you have reliable bandwidth service, but there are no guarantees of performance.

Typical services that fall into this category are DSL, Cable broadband, WiFi hot spots, 3G and 4G wireless and consumer oriented satellite service. Beyond the best effort delivery, what helps to hold the cost down is the use of shared asymmetrical bandwidth.

Shared means just that. There is a pool of bandwidth to connect to the Internet that is shared among dozens or hundreds of simultaneous users. How much you get at any given moment is determined by how many other users are online to divide up that bandwidth pool.

Asymmetrical means that your download and upload speeds are different. Typically, you get several to a order of magnitude (10x) faster speed on download that upload. Why? It’s because most Internet users are accessing web pages or streaming video. These are primarily one way activities. You need the extra bandwidth for those large file transfers from the server on the Internet to your PC.

There are some factors that muddy the waters. The consumer oriented services have business equivalents that are basically the same service but installed at commercial than residential addresses. They are often 2x to 3x the cost for business users. You do get better customer service and, often, the option for static IP addresses if you need them to run a server. Most consumer services prohibit running servers or sharing the bandwidth, such as offering a free WiFi hotspot.

So are these lower cost services something to avoid? Not at all, if they meet your needs. Even home broadband can be highly reliable and quickly repaired if the line is cut or equipment fails. It’s not unusual to get higher bandwidths, as high as 50 or 100 Mbps download and 5 to 10 Mbps upload, for roughly the same cost as a 1.5 Mbps T1 or 3 Mbps EoC line. If most of what your employees do is use email and web browsers or view video clips, you’ll likely get faster speeds for everyone with cable broadband than even bonded T1 lines. Sometimes wireless is all that will work at your location. In that case, a 3G or 4G cellular broadband can save the day when there are no wireline services available.

On the other hand, if you are running enterprise applications, especially in the cloud, or have converted your entire telephone system to VoIP, you’re not going to be very happy with the lower end services. The variability in bandwidth, latency and jitter will drive you crazy and drive your customers crazy as well. You’ll be much better off with dedicated symmetrical bandwidth. In fact, you may well want a direct connection to your cloud service provider or between business locations rather than deal with the vagaries and security issues of the Internet. Many companies need both: dedicated private line service for internal operations and an Internet connection to reach customers and access data.

Asymmetric Bandwidth is Hot for Business

By: John Shepler

What has characterized serious bandwidth for business applications has been symmetry, or having the same Mbps capacity in both the up (transmit) and down (receive) directions. That’s being challenged, now, by new service products that promote asymmetry. Asymmetry means having a different bandwidth available depending on whether you are uploading or downloading. Let’s have a look at why this is happening and if it can be advantageous for your business.

Symmetry has its roots in telecom services that go back to the development of digital line transmission a half-century ago. The inventor of the T-Carrier standards, including the ubiquitous T1 line, was Bell Labs. Bell’s mission was to serve the telephone companies, so the digitization of telephone calls preceded computer to computer communications by decades. Switching from analog to digital long lines virtually eliminated the noise, distortion and crosstalk effects that plagued domestic long distance and international phone calls. It also enabled systems that could transmit hundreds and thousands of simultaneous phone calls on a single circuit.

Why symmetrical operation? Phone calls are bi-directional in nature. It doesn’t matter which end of the call you are on. You need the same line characteristics so that you can talk and listen simultaneously. This results in transmit and receive paths that are identical in design.

When T1 lines, DS3 connections and fiber optic circuits were pressed into service to meet the demand for computer communications, they automatically came with symmetrical bandwidth as well as dedicated circuits, synchronized channels and low latency and jitter. These features of Time Division Multiplexing (TDM) get the job done, but at a price.

Asymmetry has its roots in the rise of the Internet and consumer based Internet Service Providers (ISPs). When you access a web site, you send a small burst of packets to tell the server what you want and get back a large burst of packets that carry text, images, audio and video. Nearly all web access by users requires a lot more bandwidth in the download direction than in the upload direction.

This works well for telephone companies providing DSL over shared phone lines and cable companies using spare channels to deliver broadband Internet. Cable, especially, is a one-way medium. When TV was the only service, all channel content went from the head end to the consumer. For asymmetrical broadband, many fewer channels have to be allocated for the upload direction. That leaves the rest available for higher download speeds at premium pricing.

What some businesses, especially the smaller ones, have found is that asymmetrical DSL, cable, wireless and satellite broadband meet their needs just fine. This is especially true when their employees use the Internet primarily for web access and occasional email. Cable broadband is readily available and gives you higher download speeds for a fraction of the cost of a T1 line. When you get into higher bandwidths, say 10 to 100 Mbps, the cost differences are like night and day.

There are some hitches in this rosy scenario. Asymmetry is only one reason why DSL and Cable are cheaper than T1, DS3, Ethernet over Copper and fiber. A big driver in this cost reduction is shared rather than dedicated bandwidth. With shared bandwidth, the Mbps you have in either direction varies constantly depending on what your neighbors are doing. It’s one big bandwidth pool and the more users who are swimming in it, the less bandwidth is available to each user. This can get annoying when you have a critical project in the works and you can’t get much done because other people are downloading high definition videos.

Another difference between the symmetrical and asymmetrical services is that the symmetrical ones tend to be tariffed telecom services with Service Level Agreements (SLAs) that specify repair times for circuit outages, usually in a matter of a few hours. The consumer oriented asymmetrical services tend to be classified as “data services” and are provided on a best effort basis. The carrier will take your complaints seriously, but they may not be able to get the line fixed for some time.

Asymmetry doesn’t work for everyone. Applications like disaster backup and recovery, video conferencing, PBX & enterprise VoIP telephony, cloud computing and large file transfers between multiple business sites really need line symmetry for optimum performance. Companies running these applications also tend to need dedicated bandwidth and service level agreements to ensure maximum productivity.

Even so, the heavy competition from cable and other service providers is causing some major telecom carriers to rethink their service offerings. MegaPath, for instance, is rolling out asymmetrical service to customers at a cost savings. They are still differentiating their service with dedicated bandwidth, SLAs and Quality of Service (QoS) options for business applications that need these characteristics. Other big telecom carriers are expected to follow suit.

With so many service providers and connectivity options, how do you choose the optimum service that gives you the performance you need for the least expense?

3 Types of Clouds You Should Know About

You’ve heard the buzz and have started thinking that you might be missing something by not moving your IT services to the cloud. To help you with that decision, we’ll take a look at the 3 basic types of clouds available and some of the applications that make sense to be cloud-based.

It seems like just about everybody is in the cloud business these days. They are basically offering their own versions of 3 different cloud architectures. These are the public cloud, private cloud and hybrid cloud. All of the different cloud services run on one or more of these cloud models.

The most popular and prevalent type of cloud is the public cloud. This is a special purpose data center owned and operated by a cloud service provider who seeks to provide services to many paying customers simultaneously. The cloud data center is the type of data center we’d all like to have, but few can afford. It is in a large secure facility with fire suppression and a couple of layers of backup power. There are multiple fiber optic lines connecting to the outside world for redundancy.

In fact, redundancy is a key to successful cloud operations. One of the key selling features is reliability. In fact, many business oriented cloud companies offer Service Level Agreements (SLAs) that define the uptime you can expect, how fast service will be restored in the rare event it is lost, and what compensation you’ll receive for not having your cloud service available. These SLAs are similar to what telecom carriers offer and distinguish enterprise level cloud providers from consumer type services.

Redundancy means multiple everything. That includes servers, batteries, diesel generators, Ethernet switches, routers, wireline connections, environmental control, and staffing. Any decent cloud company has a full time technical staff ready to address issues around the cloud.

The companion to redundancy is virtualization. This is the real magic behind the cloud. Virtualization became popular with IT departments because so many applications don’t use the full capacity of the server. They either run at a fraction of the maximum throughput or occasionally burst to more than the server can handle. By connecting multiple physical servers in a virtualized environment, each application can take the resources it needs at any given moment without hogging an expensive server that mostly idles. The load can be spread among multiple physical servers automatically to handle peak loads.

In fact, this is how you can build the second type of cloud yourself. Set up your own data center as a virtualized environment of servers, storage and WAN connections and you can provide computing for your entire organization including remote business locations.This is the private cloud. You own it. You maintain it. You keep all the resources for yourself.

Economy of scale suggests that public cloud with multiple tenants are going to cost you less than running your own private could. You may want to go with the private option anyway when you have high security requirements or heavy regulatory compliance requirements. The other reason is if you have a unique environment that requires specialized hardware, software or operating systems.

A fairly new wrinkle is the private cloud in the public data center. In this case, the cloud service provider sets up a fully dedicated infrastructure that serves only your needs. It is not interconnected with the public cloud facilities. An advantage of this approach is that you can maintain the privacy of having your own cloud without the capital investment and maintenance headaches of ownership.

The third type of cloud is called the hybrid cloud. It is a combination of private and public clouds. For instance, you may use a public cloud for many of your applications but keep a smaller private cloud in-house for your most sensitive or proprietary functions. You can decide how much cross-connection occurs so that the private and public clouds can share information. You may even want a cloud service company to create a hybrid cloud for you using their public cloud infrastructure and special facilities for your dedicated private cloud.

Comcast’s 100 Gbps Core Network Supports Business

Major telecom carriers have been in the process of upgrading their core networks from 40 Gbps to 100 Gbps over the last year. Comcast is the latest to make the move, fitting Ciena’s Wave Logic 3 interfaces to their current Ciena 6500 packet optical platforms. Why would a cable company do this and how can it benefit your business?

Comcast is best known as a Cable TV company or MSO (Multi-System Operator). They serve over 20 million residential and commercial customers in 40 states and the District of Columbia with video television, high speed Internet and telephone services. You may already know that Comcast broadband service is highly popular for home, home office and small business use. It comes in on a coaxial cable and is highly affordable. But did you also know that Comcast operates one of the largest fiber optic networks in the United States behind the scenes?

Many people think that cable companies still connect everything from their head-end towers and satellite dishes to locations around town using various size coax. That was true in the early days of analog TV cable systems and master antennas for large apartment buildings. The technology has long since moved on. Now everything is digital and the signals ride fiber optic cables most of the distance to your location. It’s that connection from the curb to your building that is still RG-6 coaxial copper wire.

Why? Because it works just fine and the cost of installation has already been paid. DOCSIS 3.0 modems offer broadband Internet in excess of 100 Mbps. That’s is well within the needs of most users. What’s really important to residential, home office and very small business users is low monthly cost combined with adequate performance. The shared asymmetrical bandwidth (higher download than upload speeds) and “best effort” performance is more than adequate for accessing the Internet and downloading documents, pictures and video.

Where HFC (Hybrid Fiber Cable) services run out of gas is when the need for bandwidth is high, dedicated low latency service is needed, symmetrical upload and download speeds are required, and an SLA (Service Level Agreement) is desired. These characteristics are common for traditional telecom services such as T1, DS3 and SONET fiber and the newer Ethernet services such as FastE at 100 Mbps, GigE at 1000 Mbps and 10 GigE at 10 Gbps.

What isn’t as well known is that Comcast operates an enterprise grade fiber optic core network to interconnect their many offices and provide high bandwidth connectivity to businesses. Would you be surprised to learn that Comcast operates a network that covers 147,000 fiber route miles? How about that business class services are available from 1 Mbps on up to 10 Gbps? Their business class services include dedicated Internet access, point to point Ethernet private lines, Ethernet LAN service to interconnect multiple business locations and converged layer 2 centric VPLS to support voice, video and data.

Comcast, like other major fiber optic carriers, recognizes the increasing demand for higher and higher bandwidth services. What’s driving these speed increases is more use of HD video, big data files and a rapid move to cloud computing services. The cloud, especially, present new challenges for businesses used to having all their processing in-house and connected over the corporate LAN. Cloud service providers offer the opportunity to rapidly scale resources up and down, pay only for what you use during the month, and avoid both capital investments and ongoing maintenance costs. The tradeoff is that you now need much higher and very reliable bandwidth to connect your employees to the cloud.

Comcast’s upgrade to 100 Gbps fiber optic bandwidth meets today’s perhaps tomorrow’s needs for their own use and in support of small, medium and large companies. When even this massive capability fills up, the Ciena system they’ve chosen has an upgrade path to 400 Gbps. It’s likely that we’ll see even higher speeds at 1 Tbps and beyond sooner than anyone expects.

Are you running short on bandwidth and wondering how much you can afford as an upgrade? Get multiple competitive fiber optic service quotes for Comcast Business and other high performance fiber optic carriers now. It’s likely that you can turn up your WAN bandwidth at little or no increase over your current monthly least cost.

Scalable Cloud Servers Free Trial

You’ve been thinking about moving away from in-house physical servers to cloud servers. It’s the amount of grief involved in making the move and the potential cost that has you spooked. You don’t really need a supercomputer to run your business. You’d just like to have the advantages of elasticity and pay as you go pricing. Is that a reasonable thing to ask?

You bet it is! Before you get into a contract with one of the larger cloud services companies, have a look at scalable cloud servers perfect for small and medium business applications, as well as larger corporations. This particular service offers per second billing, the ability to pay only for what you use, free setup, no contract commitments and... there’s a free trial available.

Talk about low risk. Here’s your opportunity to get into cloud computing without a lot of fuss and bother and without committing to something that you’re not sure will work for you. There’s no big learning curve involved, either. These Windows and Linux cloud servers work like physical servers you are already familiar with. Have you spent years running your servers using cPanel and WHM? You can still manage them using CPanel/WHM. You’ll be able to turn up cPanel/WHM-ready cloud servers in a matter of seconds. That’s a lot faster than you could install the software if you were sitting right next to a server in your facility.

What sort of features are available with these scalable cloud servers? You’ll get full root/administrative access and the ability to build, test and deploy servers instantly. Your data is backed up nightly. This is not an oversold service, like some VPS (Virtual Private Servers). You get guaranteed CPU cycles and can burst higher when more cycles are available. If you wish to control your cloud servers programmatically, you can use the RESTful API that is available to control cloud servers.

The company that offers these cloud servers, Atlantic.Net, operates state of the art SSAE 16 (SOC 1) Type II (formerly SAS 70) certified data centers. They are secure, fireproof and climate controlled with multiple direct connections to the Internet. Backup power ensures that your servers will always be running. This is no idle claim. The SLA (Service Level Agreement) is a 100% Uptime SLA that includes 100% network uptime, 100% hardware replacement and 100% infrastructure uptime, all with money back guarantees. The cloud itself is designed for high throughput and low latency, running at 40 Gigabits per second. There are multiple nationwide data centers located in New York, Chicago, Orlando, Dallas, Phoenix and Los Angeles.

You are probably wondering about pricing. It starts at 1.3 cents per hour or $9.49 a month for the smallest server with 256 MB RAM, 10 GB disk, a 2.4 GHz Xeon processor and a 10 Mbps network connection. It goes up from there, of course. The largest server has 16 GB of RAM, 4 x 2.4 GHz Xeon processors 750 GB of disk storage and a 70 Mbps network connection.

Cloud servers offer the benefits of owning your own server without the commitment of buying the hardware, maintaining it, paying for power and environmental controls, upgrading software and then going out to buy more when you run out of capacity. You know that can take days or weeks instead of the seconds it takes to turn up another cloud server.

Are you at least curious if cloud services are a better approach than the legacy techniques of operating in-house physical servers? Get a free trial of scalable cloud servers and give it a try before you make a final decision. Remember, even after you order one or more cloud servers, you can shut them down at any time and pay only for what you’ve used to date. It’s like having a massive data center all to yourself without having to pay for the infrastructure.

Hosted Network Monitoring Services

Metro and Wide Area Networks are becoming more and more important to businesses. The steady migration toward electronic transactions, online services and cloud storage & computing are making networks a critical part of the business infrastructure. That, in turn, is making networking monitoring a necessary function in every IT department. It breaks down to doing it yourself or contracting with a provider to monitor the network.

Companies have been monitoring their own LANs since they started installing networks. It’s logical to extend that philosophy to include any telecom links between facilities. That includes point to point networks and both public and VPN connections to the Internet. There are good reasons to rethink this approach now. Let’s have a look at how the networking monitoring processing can be improved.

One area of weakness is networks used by smaller businesses. A lot of factories, offices and retail outlets aren’t open or staffed around the clock. What’s going on in the wee hours? Who knows? A construction crew could be working late and cut through the cable that is your last mile connection. The alarm lights on the terminal equipment illuminate, but there is no one around to take action. You come in to open up in the morning and find that you have no network connection. You report it, of course, and the carrier will start the investigation process. You may or may not be back in business by noon. That’s only if you have a good SLA (Service Level Agreement) or a very proactive service provider.

There are measures you can take. You can set up a process to monitor the alarms and ping remote servers periodically to make sure the link is still up. If something goes wrong, you can have it send you or someone on-call in your IT department a text message. Somebody sill has to be awake enough to get the alert and then start working the problem. That involves figuring out if the outage in on the telecom link or in your equipment and contacting the right party to get some corrective action.

Large companies with 24/7 coverage of their data centers and other IT assets may consider this part of their charter. Small and medium companies, especially those with branch offices and critical e-commerce infrastructure, may have the need for faster response but not the budget to provide “just in case” staffing. These are the companies that hosted network monitoring services work wonders for. With hosted monitoring, the responsibility of what’s happening beyond your network’s edge belongs to the service provider. They do have the automated equipment and round-the-clock staffing to keep an eye on every network link to make sure that it is working properly.

In most situations, the network edge is a managed router installed by the service provider. This equipment terminates the line with the proper interface, be it T1, DS3, EoC, EoF or SONET. The other side of the router is where you connect, generally with an Ethernet interface. The router itself is considered “in the loop” as far as network monitoring and testing is concerned. If anything goes wrong, the provider has the ability to test functionality through all their equipment and lines, right on up to your Ethernet connection.

In some cases, you even have the option of letting the service provider include your internal local network within their networking monitoring service. You decide whether to let them have access to the entire network or just a portion. This is the ultimate level of support for smaller companies that have little or no on-site IT staffing.

A particularly robust network security solution is provided by MegaPath, a major facilities-based carrier. MegaPath goes far beyond just monitoring to ensure the network is “up.” They include comprehensive Unified Threat Management (UTM) to implement network security. This involves an advanced firewall, intrusion prevention, anti-virus and anti-spam filtering, web application control and data loss prevention. Network management involves deep packet inspection and uptime monitoring that monitors for latency, jitter, delays and packet loss. It is sometimes difficult for even larger companies to provide this depth of networking monitoring and security.

Are you interested in better management of your network connections at a reasonable cost? You should look into hosted network monitoring and security services suitable for the size of your business and criticality of your network.

Symmetrical Internet Providers

Most people who use the Internet are consumers, not producers of content. The mix of content has migrated from largely text to largely images and streaming video over the last couple of decades. Even so, the connection arrangement for broadband Internet access has remained asymmetrical with bandwidth in the downward direction 5 to 10 times that provided in the upload direction.

Why is that the setup? Think about how you access the Web on a PC, tablet or smartphone. It almost always involves selecting some content to read or view. The selection process is a matter of mouse clicks or keyboard entry. Those are pretty low bandwidth activities. The viewing of the results or the acquisition of a file is just the opposite. A server assembles those results and delivers fairly large pages consisting of text, graphics, photo images and perhaps video. All of that material comprises a lot of bytes and needs a considerable bandwidth to deliver in any reasonable time.

Since bandwidth is a scarce commodity, relatively speaking, there is a noticeable cost involved in providing the wireline or wireless channel for transport. There is no point in provisioning a fast upload link if it is only going to be lightly used. It’s download that customers value and demand as much as they can get for their broadband dollar.

Social media is changing the mix of upload and download requirements. When most of us were web page readers, the low bandwidth upload and high bandwidth download channels were the obvious setup. Today, many more users are creators as well as consumers of content. They post to blogs and Facebook. They upload photos and videos as well as download them. New applications like VoIP telephony and video conferencing consume equal amounts of bandwidth in both directions. The pressure on service providers is for more upload bandwidth as well as download bandwidth.

Businesses have had the symmetrical bandwidth requirement for a long time. It’s the businesses that run those servers that provide content to their customers. Large files going to the server need lots of bandwidth. There may be more email flowing out of a business than into it. Some businesses are providing streaming video content to the Internet and consume more bandwidth in the upload direction than the download direction. Cloud services have heavy traffic moving in both directions.

Right now, your choices in Internet bandwidth services can be divided into symmetrical and asymmetrical categories. Symmetrical means that upload and download speeds are the same. Asymmetrical means one direction is much faster than the other. That’s almost always the download stream.

Traditional telecom services are symmetrical. They were developed by the telephone industry and later adapted for transporting data. Telephone is inherently two-way with no difference in the amount of traffic flowing in one direction versus the other. If you order a T1 line, Ethernet over Copper, DS3 connection or OC-3 fiber optic service, you will get symmetrical bandwidth by default.

Symmetrical bandwidth services also tend to be dedicated Internet services, abbreviated DIA for Dedicated Internet Access. What does dedicated mean? It means that the bandwidth is assigned exclusively for your use. A 10 Mbps EoC Internet service gives you 10 Mbps in both directions, called 10 x 10 Mbps, anytime you want to use it. Any bandwidth you don’t need at the moment sits idle until you do.

Symmetrical bandwidth services are often covered by Service Level Agreements or SLAs. These agreements spell out the technical characteristics of the line, such as bandwidth, jitter, latency and packet loss. They also define such things as MTTR or Mean TIme To Repair for any outages that might occur. There are generally remedies available, like refunds on your bill, if the service provider can’t deliver to the terms of the SLA.

Asymmetrical bandwidth services are generally targeted toward consumers where price is far more important than performance. The bandwidth is shared among multiple users, not dedicated to you alone. That means that your download and upload speeds will vary depending on how many others are trying to use the service at the same time. Instead of SLAs, asymmetrical services are provided on a “best effort” basis that lacks any guarantees.

There’s quite a difference in price and performance between symmetrical and asymmetrical bandwidth services. Which is right for your business? Get prices and features from business broadband Internet providers to compare options and select the best match for your company needs.

3 Mbps to 6 Mbps Bonded Internet Access

Business Internet access is critical to communicating with customers and perhaps taking and fulfilling orders. You want rock solid stability and decent bandwidth, but at a price that won’t break the bank. Here’s a look at how you can incrementally increase your Internet connection speed to match your business activity.

Not that long ago, you had a couple of choices for dedicated Internet access. You could get a T1 line at 1.5 Mbps or move up to a T3 line (DS3 bandwidth) at 45 Mbps. There really wasn’t anything in-between. Shared bandwidth services offer a larger range of choices, but shared bandwidth means variable performance and assurance of availability. You also have to contend with asymmetrical speed, where download line speed is 10x the upload line speed.

Dedicated Internet access, like T1 and T3, offers symmetrical bandwidth that is the same for both upload and download, a fixed line speed that doesn’t vary, and high availability with a Service Level Agreement (SLA). The one issue is cost, especially when you need more than what a T1 line can provide but not the full capacity of a T3 line.

Sometimes you can get what’s called a fractional line service. The service provider installs a full capacity line, but rate limits your bandwidth. The result is referred to a fractional T3 or fractional DS3 service. It saves some money over the full service level but isn’t that great of a deal on a per Mbps cost basis.

A better option today is to order bonded line service to increase your bandwidth. Bonding is an industry standard for connecting multiple lines of the same type to combine their bandwidths. For instance, you can bond two T1 lines together and get 3 Mbps instead of 1.5 Mbps. The view from your router is one larger bandwidth service rather than juggling two separate lines. That bonding process takes place within the Customer Premises Equipment (CPE) that is installed by the service provider.

Bonding is a great way to increase your bandwidth incrementally, but there are a couple of things to consider. First, you can’t just go out and buy a second T1 line from just anybody. You have to get your bonded lines from the same carrier. Remember that it is the service provider who does the bonding through equipment at both ends of the line.

Also, the cost goes up by the same increment as the bandwidth. In other words, two T1 lines cost twice as much as one T1 line. There is no economy of scale. That’s no big deal if you are happy with doubling your line speed and your cost versus have to pay 10x the price to move up to the next standard line speed increment of T3. However, this technique does get less attractive with the more lines that you bond in.

Yes, you can go beyond double bonded T1. Bond three T1 lines for 4.5 Mbps, four lines for 6 Mbps, 5 lines for 7.5 Mbps, 6 lines for 8 Mbps, 7 lines for 9.5 Mbps or 8 T1 lines to get 11 Mbps. By the time you get 8 T1 lines bonded, the cost may be approaching what you’d pay for 45 Mbps T3 and you’d have a lot higher line speed.

There is an alternate bonded line service that may give you more bandwidth for less money. This is Ethernet over Copper or EoC. Like bonded T1, EoC uses multiple wire pairs to transport the signal. Providers will bond 2, 4, 6 or 8 pair to increase the speed of Ethernet over Copper service. Unlike T1, EoC offers a much wider range of available bandwidth options. For the price of a T1 line, you can get 2 or 3 Mbps EoC. Other speed options include 5, 10, 15, 20, 25, 30, 35, 40 and 45 Mbps. Cost per Mbps actually decreases as you order higher bandwidth levels.

The one limitation of Ethernet over Copper is availability. It is a newer service and not all central offices are equipped to provide this line service. Also, EoC is highly distance sensitive. You need to be close to your CO to get the highest speeds. Otherwise you may top out at 10 or 15 Mbps. That’s still about the best you can do with bonded T1 and for considerably less cost.

Are you looking for a rock solid connection to the Internet to support your business activities. If so, check availability and pricing for bonded T1 and EoC dedicated Internet access options.

Internet Service Without The Outages

The Internet is an amazing place for finding out just about anything related to anything. The sum total of human knowledge is migrating online. Even old books and papers are being scanned and loaded onto webpages and data bases. Combine that with real-time access to shopping, financial services, music and video and you are pretty much attached to the Internet at the hip... or at least the brain. The one major aggravation of Internet everything is when you just can’t get to it.

Internet outages are almost always local events now. The network is so large and so robust that the entire Internet just doesn’t go down. It only seems that way. Perhaps it’s your favorite site or application that is temporarily offline. Perhaps you just can’t get to anything at all.

I’ve felt this pain to varying degrees over the years. As a night owl, I know that the wee hours are the time that network administrators target to do their maintenance. That means my ISP can go offline for an hour or two without warning. It also means that any given online service my be down for maintenance with little or no notice.

Then there are the unplanned and uncontrolled outages. Construction work is famous for taking down telecom services. It’s so prevalent it has a name. They call it “backhoe fade.” It’s pretty much what it sounds like. Someone with a backhoe digs in the wrong place and chops through a wire. A year or two ago, they chopped through a fiber optic cable. There were over 100 strands in that cable and my service was on one of the last to be fused back together. No Internet for two days.

Well, not exactly. The cable modem was dead for two days. I was getting things done at any restaurant where they had free WiFi that wasn’t affected. Inconvenient? Yes, but it got me through.

I’m tied to the Internet for my livelihood, but a local outage isn’t the kiss of death. It’s just a major inconvenience. The reason for this is that all of my hosting, dozens of domains worth, is done elsewhere. In fact, I insist on having multiple hosting services located in different data centers in different cities. That way a local disaster won’t take everything down at once. This happened about 8 years back. Remember the 4 hurricanes that hit Florida in 2004? One of them flooded the building my web host was in. Even though they were on a higher floor, the communications lines were affected so no data was going in or out.

This hints at the first thing you can do to protect your business from Internet outages. Don’t put all of your eggs or servers in one basket. You have more protection when the services you use are divvied out geographically. Disasters rarely affect more than a limited area. This is true for cloud services too. Your cloud provider needs to have diverse backup solutions or you need more than one cloud. Nowadays, that also means you need more than one way to get to the cloud.

Backhoe fade is a fact of Internet access, although there are more and less risky solutions. All in all, you are better off with dedicated Internet access that has an SLA or Service Level Agreement. The really cheap Internet services, DSL and Cable, are shared and not dedicated to you alone. They are also treated as “information services” not telecom services, meaning that the providers don’t jump nearly as high or as fast when something goes wrong. T1 lines, Ethernet over Copper, Ethernet over Fiber and SONET perform better, have faster mean times to repair and cost more... as you would expect.

It’s good to have diversity in your connectivity. Two T1 lines are better than one. Ethernet over Copper using multiple pairs is more reliable than anything coming in on a single pair. Even better is copper backup for fiber services, even thought it may be slower. There is no one cable that has both the copper wires and fiber strands in it. A cable broadband service can be an inexpensive backup service to your dedicated lines since it doesn’t use telco wiring. Wireless broadband is an excellent backup that also doesn’t have to be that costly. Your smartphone gives you a level of redundancy when your desktop PC goes down. There are fixed wireless services designed for business backup running on 3G and 4G cellular networks. You can set these up for automatic failover so that service won’t be interrupted if you lose a landline.

How much you need to concern yourself with redundancy and disaster recovery depends on what happens when you lose your connection to the Internet. Is it a minor inconvenience or does everything come to a screeching halt? If that’s the case, make sure you have at least two ways of connecting and getting your work done. They don’t have to be the same bandwidth or guaranteed availability. Just make sure that there is no single point of failure that will knock them both out at the same time. There are lots of different services available. Check prices and features so you can get the best mix of business bandwidth services available for your particular location.

5 Ways to Access An MPLS Network

MPLS networks have become a highly desirable option to expensive proprietary WAN networks or the public Internet with its performance and security issues. Let’s take a look at what MPLS networks have to offer and the variety of options that you can use to gain access.

You might think of an MPLS network as something of a private Internet for business. MPLS networks are privately owned and operated and don’t offer resources or connectivity for residential users. MPLS is a B2B or Business to Business service. There are numerous service providers, each with their own MPLS networks having regional, national or international service footprints. In addition, there are service providers who specialize in interconnecting MPLS networks to create an even larger reach. The result is a multiple-MPLS or MPLS Mesh network.

MPLS is often the core network of a major service provider. The reason is the versatility offered by this technology. The underlying network is either IP native or SONET/SDH fiber optic service at 10 Gbps or higher. Many networks are now migrating from 40 Gbps to 100 Gbps, which is considered state of the art. What makes the network MPLS is a unique switching and routing scheme that is protocol-agnostic.

The name MPLS is an acronym for Multi-Protocol Label Switching. Multi-Protocol means that the network will accept Voice, Data or Video IP, SONET, T-Carrier or other traffic types. At any given time, the network may be transporting a wide variety of protocols without corruption or interference. Label Switching is the technique that wraps each packet that enters the network with a tag that is used only to forward that packet to the correct destination with an appropriate class of service. Those labels are removed as the packets exit the network in exactly the same state as they arrived.

Think of MPLS networks as private superhighway systems and access as the on and off ramps. A major advantage of procuring MPLS network service for long haul transport is that you only need to worry about getting your traffic to and from the network. The network operator optimizes performance of the MPLS network to ensure adequate bandwidth with low latency, jitter and packet loss. You need the means to get to and from that network with your traffic intact.

EarthLink Business offers a nationwide access-agnostic MPLS network with Service Level Agreements (SLA) based on Class of Service (CoS). They offer 5 different access technologies based on what makes sense at each business location. Note that you can easily mix and match access methods and still maintain complete CoS right up to your own network edge. Here’s what you have to pick from.

The classic and still most popular access method is T1 lines. They are almost universally available over common twisted pair telco wiring that is already installed to most business locations. T1 lines offer 1.5 Mbps symmetrical bandwidth that can be increased by bonding more T1 lines together. EarthLink boasts 4 hour mean time to repair (MTTR) private T1 lines if there is ever a link problem.

Many companies have looked to DSL as a lower cost alternative to T1. ADSL is an asymmetrical bandwidth service with higher download than upload speeds. Earthlink is the first provider to offer CoS traffic management over DSL, making this access method viable for serious business use.

Ethernet over copper (EoC) and fiber (EoF) is a strong competitor to T1, DS3 and higher speed SONET fiber services. Ethernet is a better match to IP traffic than switched-circuit oriented TDM (Time Division Multiplexing) technologies. Ethernet is highly scalable and lower in cost on an Mbps basis, where available.

Wireless access works for companies with new location that need rapid provisioning and for low cost access where DSL is unavailable. 3G and 4G cellular-based bandwidth is often available in rural areas and offers T1 and better speeds without the landline. Fixed wireless microwave transmission offers higher speeds that can be an effective alternative to fiber.

Another unique service from EarthLink is MPLS IPsec. You may recognize IPsec or IP SECurity as a VPN technology used to make connections over the Internet secure. The security comes from using the 3DES encryption algorithm (168 bit). That’s the finance industry standard for network layer encryption. IPsec allows businesses to procure Internet access from a local provider in outlying areas and connect securely to the corporate MPLS network.

Is MPLS a good fit for your business networking needs? Which access methods are right for your various locations? You can easily find this out with a complementary set of MPLS network and access service quotes to compare with your current WAN solution. You may be surprised by the savings possible.

3 Mbps T1 vs EoC Throwdown

There’s a battle that’s been brewing for a couple of years and is now raging in full force in many markets. That’s the contest between bonded T1 lines and Ethernet over Copper. Regardless of who the technical winner is, the business winner could be you.

Let’s take a step back and review just what this battle is about and who the players are. Ultimately, it’s all about bandwidth and cost. Bandwidth needs to go up and cost needs to come down. Why? Because businesses are becoming more and more dependent on connectivity. They are especially tied to the Internet, but also need to connect privately to remote data centers and clouds. Telephone connectivity is moving from a completely separate service to something tied-in with data connections and/or the Internet.

The two technology contenders in fierce competition are T1 lines, the reigning champ, and Ethernet over Copper (EoC), the up and coming challenger. In some ways, these services are more alike than different. Both are wireline services. In fact, both use the exact same twisted pair copper telco wiring that comes in multi-pair cables from the incumbent telephone company. That’s your business telephone wiring. What you may not realize is that there are extra wires in that cable that can be used for private data lines or Internet connections. What else you may not realize is that there are many competitive carriers who would like to provide you with those digital services.

How is this possible if the cable bundle runs directly to the telephone company’s central office? By law, the local or incumbent phone company owns the copper telephone wires that run underground or overhead. However, other companies can lease the unused pairs. In fact, other companies can even install their own termination equipment within the phone company’s office. That lets competitive carriers offer services that compete with phone company offerings or even services that the phone companies don’t offer.

T1 line service was actually developed by the telephone industry to transport multiple telephone calls on one line. Later on, it was offered to business as a way to connect to the Internet or for private point to point data lines between two locations. T1 line technology has matured to where it is well entrenched with small, medium and larger companies. T1 can be provisioned just about anywhere you can get landline telephone service. It runs at 1.5 Mbps in both the upload and download directions. T1 is often offered with a Service Level Agreement (SLA) that guarantees availability.

The 1.5 Mbps bandwidth of a T1 line was once its main selling point. Today, 1.5 Mbps is more of an entry level service, especially for Internet access. Fortunately, there’s a solution for that. Just add more T1 lines. The trick is to combine their bandwidth through a process known as bonding. You can bond 2 to 8 T1 lines this way to get anywhere from 3 to 12 Mbps over ordinary copper telco wire. The most popular level right now is dual-bonded T1 for 3 Mbps. Many smaller companies don’t need any more bandwidth than that. The price for bonded service is the cost of one T1 lines times the number of lines you bond. There is no economy of scale.

The direct competitor to dual-bonded T1 is Ethernet over Copper or EoC. It also uses multiple copper pair, but a different modulation scheme than T1 to transport the signal down the line. The tradeoff is bandwidth vs distance. EoC is highly sensitive to the length of the telco line. Close to the Central Office (CO), you can easily get 10, 20, 30 or up to 50 Mbps. A few miles away you get can’t get any service at all. Forget EoC out in the countryside. This is a city service.

One big reason that companies choose EoC instead of T1 is that they can get higher bandwidth without the expense of bringing in fiber optic services. The construction costs can be prohibitive if your building isn’t already “lit” with fiber. The other big reason to go with Ethernet over Copper is cost. A 3 Mbps EoC service will cost about the same as 1.5 Mbps T1. Another popular option is to move up to 10 Mbps for about the same price as dual or triple bonded T1, depending on location.

Which service will win the “battle of the bandwidths?” For now, they’re pretty well matched, with T1 having the advantages of near universal availability and being the incumbent service. EoC is coming on strong, as companies find they need higher levels of bandwidth and like the price advantage of Ethernet over Copper.

How about your situation? Which bandwidth service is right for your company? Why not get competitive prices quotes for both T1 and EoC to check out your options. Chances are, you can get better deals now than you could even a year ago.

Why T1 Is Available Where Other Line Services Aren’t

If your businesses is located off the beaten path, you may have experienced the frustration of not being able to get the same network services offered to companies downtown. You might even have come to the conclusion that there’s really nothing available to you. Oh, but there one highly reliable and reasonably priced digital telecom service that you can get almost anywhere. What is it? It’s T1.

There are a couple of misconceptions about T1 that go back to when this was something of an exclusive service. They are that T1 lines are very expensive and only available in certain areas. Neither of those is true any longer. T1 lines are available for most every business location. T1 lines are also quite reasonably priced for businesses, although not competitive with or available as residential services.

The fact that you can get T1 and not some of the “bargain” services like DSL and Cable broadband may actually be to your advantage. Those lower cost services have lower prices not because of any special technology, but because they are shared rather than dedicated bandwidth and because they are offered as “information services” with no particular guarantees of availability. Your bandwidth can vary all over the place and if the line goes down, it will get fixed when it gets fixed. T1 lines come with a Service Level Agreement (SLA) that guarantees such things as bandwidth, jitter, latency and mean time to repair.

Why would anyone buy a low budget information service instead of a professional grade telecom service? In some cases, it’s because the person placing the order isn’t all that familiar with the differences between bandwidth services and goes for the lowest price option available. In other cases, it’s because the service is being used to power a free WiFi hotspot as a service to visiting customers or for casual Internet activities that aren’t all that critical to the daily operation of the business.

T1 is so universally available because it is a highly mature technology, originally developed by the phone companies to transport two dozen phone calls at a time between switching offices. As such, it was designed to use two pair of twisted copper wires as part of a multi-pair bundle installed into nearly every business. Some of the wires in the bundle are used for phone service essential to any business. Others can be used to provide T1 line service.

T1 was also engineered with optional regenerator boxes that could be installed every mile or so to clean up and boost the signal to extend its range. This way, T1 lines can be run far out into the countryside with the same performance as those in town. That’s not so for DSL and Cable, which are pretty much constrained within the city limits and not much further.

T1 is a highly versatile line service. You can use it for dedicated Internet access, multiple telephone line trunks or as a point to point dedicated private line. It’s possible to get T1 private lines that span the nation. In this case, the are multiplexed onto long haul fiber optic circuits for most of that distance and only delivered as copper at both ends of the run.

T1 lines give you 1.5 Mbps of rock-solid exclusive bandwidth in both the upload and download directions. You don’t have to contend with any other users when you want access to the line. Prices start at under $300 a month in many locations nationwide. In lesser populated areas, the prices will be higher due to the extra effort install all the needed equipment, including regenerators, to your location.

What if 1.5 Mbps isn’t enough? You have to option to bond multiple T1 lines together to get a single larger bandwidth service. If you double bond, that is use 2 T1 lines, your bandwidth will be 3 Mbps. The number of lines you can bond together varies with location, but 10 to 12 Mbps is a practical limit in most locations. That’s plenty for most business needs.

Now that you know that T1 lines are very likely available to you at reasonable cost, how about getting T1 line service pricing and options for your business location? It sure beats having to move just because you didn’t think you could get connected.

Internet Wholesale Bandwidth Options

There are two types of organizations that buy Internet bandwidth. Most are end users. They want the access for their employees. The others are resellers. They take large Internet connections and divvy up the bandwidth to hundreds or thousands of individuals and businesses. These are Internet Service Providers (ISPs) looking to buy at wholesale and sell at retail.

The largest networks in the world, called Tier 1, don’t purchase Internet access. They are part of the core network itself. Those major world wide networks exchange traffic on basis of equals called peering. Each network gets as much traffic as it sends to the others, so all benefit and no money is exchanged.

Everyone else has to get to the Internet by accessing one of these Tier 1 networks. The next level down, the Tier 2 networks, are also very large Internet service providers. Since they don’t have the enormous global traffic to participate in peering, they purchase what is called IP Transit. This is Internet access sold on a per Megabit per second per month basis.

Smaller Tier 3 networks can purchase IP Transit from Tier 2 networks, if they are large enough to have an assigned AS or Autonomous System number (ASN) to identify them as part of the Internet. Large scale ISPs fall into this category as well as some large corporations and other organizations.

Local and regional Internet Service Providers, including WISPs (Wireless Internet Service Providers), buy DIA or Dedicated Internet Access. DIA connections are like point to point private lines, except that one end connects to the Internet. Other private line characteristics still apply. The bandwidth provided is completely dedicated to the ISP and not shared with anyone else. There are generally SLAs or Service Level Agreements that spell out characteristics such as maximum latency, jitter and packet loss as well as time to respond to outages and time to make repairs.

Dedicated also means that there are no extra charges for heavily loading the line. You can use the entire capacity of the circuit in both directions or only some of it. The price is the same.

The smallest DIA service is usually a T1 line running at 1.5 Mbps. This is a symmetrical service, meaning 1.5 Mbps upload and 1.5 Mbps download. Usually the download path is much heavier loaded than the upload path for typical Internet access. If fact most consumer Internet access is sold with 5x to 10x higher speeds on download than upload. For business users, upload speeds can be important when transferring large files to remote backup sites and servers within colocation centers.

Obviously, T1 lines can’t serve a large user base but they work great for WiFi hotspots and rural or subdivision WISP service where signed-up customers number in the dozens, not hundreds. A nice feature of T1 lines is that they can be bonded by adding more lines to double, triple and quadruple bandwidth up to about 10 or 12 Mbps. The other nice feature of T1 lines is that they are available where other line services don’t reach. If you can get business telephone system into a facility, you can probably get T1 DIA service.

The next increment in traditional telecom bandwidth is DS3, also called T3 lines. This service runs at 45 Mbps which is large enough for a good size service provider to offer competitive bandwidth. Beyond that, SONET fiber optic services include OC3 at 155 Mbps, OC12 at 622 Mbps and OC48 at 2.5 Gbps are very popular.

A strong competitor to T-Carrier and SONET bandwidth is Carrier Ethernet. It comes in two flavors, Ethernet over Copper (EoC) typically from 1 to 50 Mbps and Ethernet over Fiber (EoF) from 10 Mbps to 10 Gbps. In a some metropolitan areas, you can also get EoFW or Ethernet over Fixed Wireless at DS3 and Fast Ethernet speeds. Where available, Carrier Ethernet tends to have considerably better pricing than other services.

Do you resell Internet access to other ISPs or end users? If so, see if you can get better wholesale pricing on Dedicated Internet Access and IP Transit services.

Dedicated Bandwidth vs Cable

There are a couple of good but quite different approaches to business Internet connectivity. One is dedicated bandwidth, as exemplified by T1 lines and Ethernet over Copper. The other is Cable broadband. Let’s take a look at what each has to offer and how you would pick the right service for your business.

Small and medium size businesses that pick dedicated bandwidth services do so either because there is no shared bandwidth service readily available or because they value the consistency and service level agreements provided by the dedicated telecom providers. Companies that choose Cable broadband do so because they get a lot of bandwidth for a relatively small price. Cable BB is an established service that has been proven in years of service to residential and business users. The service availability is generally quite good, especially during business hours, and the low prices may be more important than service guarantees.

It’s important to note the definition of the term “dedicated” in this context. It doesn’t mean working extra hard like, say, a dedicated employee. What dedicated means is that a certain amount of bandwidth is reserved or dedicated to your exclusive use. If you order a T1 line, you can count on having 1.5 Mbps upload and 1.5 Mbps download capability available at all times. There is no such thing as overage charges or fair use policies. You can load that T1 line up to the limit and run it that way all month. You’ll be charged the same as if you lightly used the service during business hours and let it idle overnight.

Cable broadband is sold on a different basis. First of all, the bandwidth is shared not dedicated. You’ll notice that Cable bandwidth is specified as “up to” 10 Mbps, 100 Mbps and so on. At any given moment you may experience the full bandwidth or a small fraction of it. Why? It’s the sharing involved. What Cable companies do is lease large dedicated bandwidth circuits and then divvy that bandwidth up among their subscribers. The chunk allocated to your area may be shared by dozens or hundreds of other users. Whether or not that makes a difference depends on what you are doing on the Internet and what others on the same service are doing.

Cable broadband is designed to match the expected activities of the typical Internet user. You know that when you are looking something up online, you first query a search engine. Then you read through the first page or two of listings deciding on what site to visit. Finally, you select a site and it downloads in your browser. You may quickly go to visit another page on that site or you may spend a minute or two reading what’s on the screen.

Notice that what you were doing was sending out commands from your keyboard, waiting for a page download and then not accessing the Internet at all while you perused the material. That’s why shared bandwidth works. Not everyone is going to be typing on their keyboard or in the midst of a file download simultaneously. While you are reading, someone else can be downloading and vice versa.

This is also the reason why asymmetrical bandwidth works so well for Internet access. Asymmetrical means that upload and download speeds are vastly different. You may order 30 Mbps download with 3 Mbps or 6 Mbps upload and be perfectly satisfied. It only takes a small amount of data from the keyboard to trigger much larger data packages in the form of websites or videos to download.

Dedicated bandwidth services like T1, DS3, EoC, EoF and SONET fiber optic tend to be symmetrical. The upload and download speeds are the same. This is particularly valuable if you are communicating between organizations, sending files back and forth, uploading to a remote server or backing up files. In these cases, upload capacity counts.

The other service that works much better over dedicated rather than shared bandwidth is VoIP telephony. In fact, you are much better off connecting directly to your VoIP service provider with a dedicated T1 line or SIP trunk than using the Internet at all. The Internet offers no class of service controls so your sensitive voice packets can easily get pushed around by someone else’s data packets. That situation is even worse on shared bandwidth access services where your bandwidth varies all over the place.

Is your business in need of Internet access, point to point connections or multi-location connectivity? Check prices on dedicated and shared bandwidth options and get complementary expert advice on what services make the most sense for your business requirements.

Broadband Business Internet Service Options

Nearly every business today is connected to the Internet or soon will be. Even those mom and pop operations that still use the mechanical credit card machines will soon use electronic card verification, email and at least a brochure website. Businesses that are already seasoned users of the Web are looking to upgrade their bandwidth to support a move to cloud services. Let’s compare and contrast the various options you have for a broadband Internet connection.

Business Internet broadband services generally fall into two categories. They are shared and dedicated connections. Shared connections are similar in design to residential broadband services. The fact that the bandwidth is divvied up among many users lowers the cost for all. Dedicated services allocate a certain bandwidth to your connection and it does not vary regardless of what other users are doing. These services also tend to come with SLAs or Service Level Agreements that spell out technical parameters and availability commitments.

Shared bandwidth services include Cable Broadband, DSL, 3G and 4G Wireless, and two-way Satellite Internet. What they all have in common is that the actual bandwidth you’ll see varies with the number of other users and what they are doing. These services are sold as speeds “up to” a certain number of Mbps. That means what it says. You may get the full speed the connection is capable of or you may get a tenth of that at any given time.

These variations may or may not bother you. If you are running enterprise VoIP or bandwidth sensitive business processes, your variable connection may not support the performance you have in mind. On the other hand, if you use the Internet at work the same way you use it at home for email, Web browsing, or accessing pre-recorded audio and video, you may be quite satisfied with the service and delighted with the cost savings. Some services, like 3G wireless and Satellite are often used to support electronic credit card machines in lieu of using a phone line.

Dedicated Internet access connections, such as T1 lines and Ethernet over Copper, have rock solid bandwidth and generally excellent latency, jitter and packet loss characteristics. These are the same lines that you would use to interconnect business connections on a private line service. As Internet connections, they have one termination at your location and the other at your Internet service providers location.

Dedicated Internet access supports Web and email servers. The also support multiple users accessing the Internet and VPNs (Virtual Private Networks). If you are going to stream content to Internet users, you’ll want a DIA (Dedicated Internet Access) connection from the server to the Internet.

Ethernet over Copper (EoC) has become very popular as both a private line and DIA connection. You can often get twice the bandwidth you could with a T1 line costing the same price. Like T1, EoC is provisioned over twisted pair copper telco wiring to keep construction costs down.

Larger companies and those with demanding applications such as video transport move up to fiber optic services, such as OC3 to OC768 SONET and Ethernet over Fiber (EoF) 100 Mbps Fast Ethernet, 1 Gbps GigE and 10 Gbps 10GigE bandwidth services. All of these are dedicated services with service level agreements.

How do you decide which broadband service is right for your business? Perhaps the best way is to compare prices, availability and features for the range of Broadband Business Internet Service options available for your location. Most business grade broadband services are available only for business locations and not residences, despite similarities with consumer Internet services.

D3 vs DS3 Bandwidth Choices

Medium and larger size companies have long chosen DS3 services to obtain the bandwidth they need for broadband Internet access. Now there’s a new player in the marketplace that is looking to complement if not displace the venerable DS3 connection.

If you need business bandwidth higher than you can get by bonding T1 lines, you already know about DS3. But how much do you know about D3?

D3 is short for DOCSIS 3.0, a cable broadband standard that gives HFC (Hybrid Fiber Cable) systems a capability that rivals fiber to the premises. It is now possible to get 50 Mbps for business use from cable systems in many cities. Some have 100 Mbps available and more will have that service offering soon. DOCSIS 3.0 can provide 152 Mbps, with even higher speeds possible. Compare that with DS3 at 45 Mbps and you can see why there is a natural competition between the services.

The raw bandwidth specs don’t tell the whole story, however. D3 and DS3 are different technologies with different characteristics. You may find that one or both of these services make sense for your business.

DS3 stands for Digital Signal, level 3. It was developed as part of the T-Carrier specification by Bell Labs for use by the telephone companies to transport up to 672 simultaneous telephone calls between phone company switching centers. When provisioned over coaxial copper lines, it is called T3 line service. If you suspect that T3 is related to T1, you are right. A T3 line can transport the equivalent of 28 T1 lines on its higher bandwidth.

DOCSIS 3.0 has a Cable TV rather than a telephone company heritage. The DOCSIS standard was developed by CableLabs (Cable Television Laboratories, Inc.) with contributions from other companies serving the cable industry. If you have Cable broadband, you are using a DOCSIS modem. It’s only a question of which version you are using. The original was DOCSIS 1.0, which has been supplanted by DOCSIS 1.1, DOCSIS 2.0 and now DOCSIS 3.0.

DS3 is based on multiplexing 672 channels of 64 Kbps each to create total bandwidth of 43 Mbps. Add the necessary synchronization and control bits and you have a bandwidth of 44.736 Mbps. Why so many channels? Each of those 64K channels is just the right size to carry one telephone call. That’s the telco heritage of DS3. Combine all the channels into one large pipe and you have nearly 45 Mbps of digital bandwidth.

D3 is also based on channels. In this case, each channel is 6 MHz wide. That’s the width of one television channel. Everything on a cable system is treated as a TV channel, so broadband services have to fit into those channels to get through the amplifiers and wiring on the system without interfering with any other channels. A 6 MHz channel can transport a 38 Mbps broadband signal in one direction. Cable operators bond channels together to get higher bandwidths. With 4 bonded channels, DOCSIS 3.0 can deliver a download speed of 152 Mbps.

So, are D3 and DS3 the same beyond their different technology heritages? Not really. The telco heritage of DS3 means that it is a dedicated symmetrical bandwidth service. You get 45 Mbps in both the upload and download directions. That bandwidth never varies. It is called dedicated because it is completely dedicated to your needs. Anytime you don’t use the full 45 Mbps, it just sits there and idles while waiting for more data.

D3 is an asymmetrical shared bandwidth service. You get different speeds in the upload and download directions. Download is faster to reflect the fact that most users download more content from the Internet than they upload. Typical business bandwidth services are 50 Mbps download and 10 Mbps upload or 100 Mbps download with 10 Mbps upload. This bandwidth is shared among many users on the system. Thus, you may experience your access speed varying all over the place depending on what other users are doing. If a lot of them are downloading movies or big software updates, everyone’s speed will be slowed.

DS3 service is generally sold with an SLA or Service Level Agreement that describes the expected performance and availability of the service, plus remedies if the provider doesn’t deliver as promised. D3 is a “best effort” service with no specific performance guarantees. Even so, it is in the provider’s best interest to provide adequate resources and service availability to keep the customers happy.

The difference in services are most dramatic when you look at the pricing. You might pay several thousand dollars a month for DS3 service with an SLA. D3 will probably cost you a tenth of that, with no guarantees. Which will work for your needs depends on if the cable system passes your business and if you can live with the variations in performance and lack of guarantees. Some companies have DS3 or even T1 lines installed for their mission critical or performance sensitive applications and D3 for general Internet access and low cost backup to their telecom services.
