Extending Ethernet over MPLS Networks

Ethernet started out as a local area network protocol, but is quickly becoming the metropolitan area network protocol of choice. It offers easy interfacing to existing wired and wireless business networks, rapid bandwidth scaling without equipment changes, and a lower cost structure than traditional telecom services. If Ethernet is so great for the LAN and MAN, how about Ethernet for the WAN?

Ethernet WAN is enjoying a rising popularity, especially among companies with multiple business sites located across the United States and across international borders. You can get dedicated point to point wired Ethernet connections between any two locations, but a competing methodology that is gaining steam is Ethernet over MPLS.

Why use an MPLS network to transport your Ethernet traffic? The first reason is that MPLS networks are already in place and going where you want to send your traffic. Sure, you can custom engineer a dedicated private line service, but why re-invent the wheel? Ethernet is easily transported over MPLS networks using Pseudowire encapsulation that emulates the wireline it competes with. Which do you think is going to be less expensive? Paying for a custom point to point wireline connection or being one stream of traffic on a large MPLS network?

The way it tends to work out is that short haul Ethernet links have the cost advantage when implemented as dedicated lines. This is especially true if you are nowhere near an MPLS carrier node. Once you start looking at coast to coast transport or a situation where you want multiple Ethernet LANs connected in a transparent mesh network, MPLS networks gain the advantage. MPLS also has the edge when you want to cross international borders to include foreign sites on your corporate network.

Carriers may be muddying the water even further by offering Ethernet line services that consist of copper or fiber Ethernet access connections to their MPLS network core, where the long haul Ethernet transport really takes place.

There are several types of Ethernet services that are really popular right now. One is E-Line or Ethernet Private Line service. This is a standardized service specified by the MEF (Metro Ethernet Forum). It gives you a Carrier Ethernet connection that bridges two LANs. A variation is EVPL or Ethernet Virtual Private LIne. What EVPL does is let you use a single physical Ethernet port to connect to multiple Ethernet private lines going to out to geographically diverse locations. This is something you could use to replace a star network built on independent wireline connections to those same remote locations.

Another popular service is E-LAN or Ethernet LAN service, also called VPLS or Virtual Private LAN Service when implemented on an IP/MPLS network. While Ethernet Line Service replaces dedicated point to point telecom lines, Ethernet LAN is a meshed network service that interconnects multiple locations on an any-to-any basis. With VPLS, you bridge your multiple LANs so that they act as one giant LAN network. That’s true even if you have a hundred or thousand sites in the U.S. and and equal number spread out over the globe.

What carrier can offer this level of MPLS networking? Actually, there are several to choose from. If one can’t serve all your sites, multiple carriers can share traffic through a E-NNI or Ethernet Network to Network Interface to reach all locations with VPLS or E-Line connections. If you need this type of connectivity, you may be surprised by how affordable it has become recently. Get Ethernet over MPLS service prices now and see how far your network can really reach.

10 Gigabit Bandwidth Options

Metropolitan and wide area network speeds are on the rise. Undersea cables are being upgraded from 10 to 40 and soon 100 Gbps bandwidths, with terrestrial fiber runs moving to 100 Gbps now. Likewise, major corporations, healthcare providers and video content producers are starting to feel the squeeze of too small network connections. Fortunately, there are more options and better pricing available today than ever before.

There are several practical solutions to increasing your MAN or WAN bandwidth above the Gigabit per second level and up to 10 Gbps. Let’s see what we can do with SONET, Ethernet, Wavelength and Dark Fiber.

SONET is the telecom fiber optic standard invented by Bell Labs for the telephone industry. It was originally deployed to transport thousands upon thousands of simultaneous telephone calls between switching centers. SONET has evolved to carry data as well as digitized phone calls. As it turns out, voice traffic is in the minority now.

SONET stands for Synchronous Optical NETwork. That describes how it is designed. This is a tightly synchronized time division multiplexed system intended for switched circuit implementation. There are specific service levels associated with SONET levels. These are designed as OC or Optical Carrier levels. The lowest generally available is OC-3 at 155 Mbps, followed by OC-12 at 622 Mbps.

The next level OC-24 takes you to the Gigabit level at 1.24 Gbps. OC-24 isn’t as commonly deployed as the next level, OC-48 at 2.5 Gbps. OC-48 is becoming the new high bandwidth standard for organizations that need high speed private lines or dedicated Internet connections. OC-192 is the 10 Gigabit service level, running at a line rate of 9.95 Gbps. From there you jump up to OC-768 at 40 Gbps. You’ll recognize that as a backbone network bandwidth for fiber optic carriers. OC-768 isn’t generally required at the corporate level just yet.

Notice that there are fairly wide gaps in the service levels between SONET OC levels. If you need 2 Gbps, OC-48 service at 2.5 Gbps makes sense. However, if you need 3 Gbps, you have to go all the way up to OC-192 at 10 Gbps. In some cases, you can find fractional OC-48 service at a better price. This is simply OC-48 that is throttled to provide only the 3 Gbps or other bandwidth you need. There might not be much cost savings, since OC-48 is a standard service level and fractional SONET services are a special order, if available.

Carrier Ethernet is a far more scalable service than SONET. It does have industry standard service levels, such as 100 Mbps Fast Ethernet, 1 Gbps Gigabit Ethernet and 10 Gbps 10 GigE. Most service providers will allow you to scale your service in small increments up to the maximum capacity of the installed port. With a 10 GigE Port, you can easily get 3 Gbps, 9 Gbps or bandwidths in-between. Since Ethernet networks were designed with this scalability in mind from the beginning, service level changes are fairly automated and can be made in a matter of days, if not hours, with no equipment changes needed.

Wavelength services are offered for high performance latency sensitive applications. Dense Wavelength Division Multiplexing (DWDM) splits the fiber optic laser beam into dozens of individual wavelengths or colors that act as independent private lines. There is no interconnection between wavelengths. A wavelength is dedicated to your needs and carries your traffic exclusively. Typical speeds available are 1 GigE, 2.5 Gbps, 10 Gbps, 10 GigE and 40 Gbps. Note that both SONET and Ethernet protocols are available over individual wavelengths.

Dark Fiber gives you the ultimate in flexibility. It is simply a glass strand between two of your locations. You can run any protocol you like at any speed you want over as many wavelengths as you care to deploy. Bandwidth is nearly unlimited, but the catch is that you have to buy, install and maintain the transmission equipment that feeds the fiber.

Have your requirements reached the point where 10 Gigabit bandwidth services are a reasonable consideration. The good news is that there are multiple carriers eager to bid for your business between 1 Gbps and 10 Gbps or beyond. Get competitive quotes for Gigabit and 10 Gigabit level fiber optic services now. You may be surprised how affordable these high bandwidth services have become.

Texas Fiber Optic Network Expansion

There are big things afoot in the Lone Star State. In this case, it's big network expansions from partnerships and mergers. The result is more options and fiber network availability for businesses located in Texas.

Transtelco is a major competitive provider with a fiber network that stretches from Houston to Los Angeles and dips into Northern Mexico to pick up Monterrey, Chihuahua, Nogales, and Tijuana. The have expansion plans for both Mexico and Texas routes.

Within Texas, PAETEC, another major competitive provider, has considerable fiber assets serving Dallas, Austin and Houston, to name a few of their Texas POPs (Points of Presence). PAETEC now has offices in Austin, Dallas, Fort Worth, Houston, San Antonio and The Woodlands.

What’s afoot is a joint venture between PAETEC and Transtelco that has PAETEC building out Transtelco’s fiber leg connecting El Paso and Temple. With half ownership in this project, PAETEC gains additional SONET ring diversity for its network across the southern US and into Mexico. They also have access to offer voice, Internet and fixed wireless to agencies of the state government that use services of the State of Texas Department of Information Resources.

What makes this situation even more interesting is that PAETEC has been acquired by Windstream Communication, a competitive carrier serving the southeast and midwest US, including fiber runs into Dallas, as well as a network that extends into Arkansas, Mississippi, Alabama, Georgia, Tennessee, Kentucky, Illinois, Iowa, Wisconsin, Minnesota, Michigan, Ohio, West Virginia and Virginia.

Fiber Optic Wavelength Services for San Francisco and Silicon Valley

AboveNet is expanding its high capacity fiber optic network services with new low latency wavelength services serving the San Francisco Bay Area and Silicon Valley, including key locations in Santa Clara and San Jose, California.

AboveNet’s Core Wave solutions are based on ROADM (Reconfigurable Optical Add/Drop Multiplexer) technology. It offers dynamic wavelength add/drops of multiple protocols that include Ethernet, TDM, storage and video transport. This makes for an array of flexible service options, scalability and fast provisioning.

Compared to legacy network designs, Core Wave shows the path that all fiber optic networks will be taking in the future. Business needs are too dynamic to be straight-jacketed into a few single protocol service levels or difficult to modify equipment configurations. By basing their network on DWDM with ROADM and deploying services via wavelength, AboveNet can offer businesses whatever connectivity they need with the option to make changes and additions easily.

The beauty of wavelengths and ROADM is that you can manage traffic optically, without the need to do an optical to electrical to optical conversion process. This allows you to add a wavelength, drop off a wavelength or simply pass the wavelength (cut-through) without affecting it. The ROADM doesn’t have to know or care what protocol the traffic is on the wavelength because it doesn’t dissect the signal at that level. ROADMs give a whole new meaning to the idea of a “transparent” network.

What type of fiber optic services is AboveNet making available in the San Francisco Bay Area? You have dedicated bandwidth at 1 Gbps, 2.5 Gbps and 10 Gbps, with both protected and unprotected options. Multi-protocol support includes Carrier Ethernet at 1 Gigabit Ethernet (GigE) and 10 Gigabit Ethernet (10GigE), SONET/SDH at OC-12 (622 Mbps) STM-4, OC-48 (2.5 Gbps) STM-16, and OC-192 (10 Gbps) STM-64. You can also transport the Fibre Channel FC-100, FC-200 and FC-400 standards for SAN (Storage Area Networks). The platform is scalable to 40 Gbps for future connectivity needs.

Core Wave is a MAN (Metropolitan Area Network) solution for point to point connectivity between business locations. AboveNet also offers long haul low latency 1 Gbps, 2.5 Gbps and 10 Gbps transparent bandwidth from their POP (Point of Presence) to enterprise locations in major metro locations. This fiber optic service bypasses the Local Exchange Carrier loops to keep everything on the AboveNet network and guarantee a full 10 Gbps connectivity. One application of this service, called eXpressWave Long Haul, is to securely connect a corporate data center and backup data center located in different markets. You can order express routing of point to point dedicated circuits with no local stops to your remote locations, as needed.

Are you doing business in the San Francisco Bay Area, including Silicon Valley, and require high bandwidth, high reliability fiber optic connectivity? If so, get quotes for fiber optic wavelength services from AboveNet and other competitive carriers serving this area of California. Similar services are also available in other locations nationwide, including low latency connections to international destinations.

OC-48 Pricing Reductions Make 2.5 Gbps Affordable

OC-48 bandwidth is a staple among regional Internet service providers and larger corporations. It forms the core or many fiber optic network backbones implemented as SONET rings over hundreds or even thousands of miles. Even with more availability than ever before, many businesses shy away from even considering this high bandwidth service in fear of the budget-busting sticker shock that they reasonably expect. It’s time to reconsider that decision.

OC-48 is one of the SONET (Synchronous Optical NETwork) standard service levels. These bandwidth levels pick up where T-carrier copper services leave off. DS3 or T3 lines provide 45 Mbps of transport. The equivalent OC or Optical Carrier level is OC-1 at 52 Mbps. OC-1 isn’t readily available as an actual line service. In practice the lowest level SONET fiber optic service is OC-3 at 155 Mbps. The next practical step up is OC-12 at 622 Mbps. In some areas you can get OC-24 at 1.25 Gbps, but a more popular level is OC-48 at 2.5 Gbps. Beyond that is OC-192 at 10 Gbps and OC-768 at 40 Gbps.

What makes OC-48 so popular? Many incumbent and competitive carriers constructed their fiber optic networks around OC-48, although some of the largest have moved on to OC-192 and OC-768. OC-48 is widely used for tributaries from OC-192 backbone nodes. Some newer fiber networks are built upon IP cores, completely bypassing legacy SONET technology. Many more are running MPLS or Ethernet over SONET.

One reason for this is that the SONET core is already in place, including all the routing and switching equipment. Another is that SONET is a proven technology that is widely supported and designed for carrier-class services. For instance, most SONET rings are dual rings that offer protection from fiber cuts and equipment failures. In the event of an outage, switching from one ring to another is accomplished in less than 50 mSec.

Once a technology that carriers kept for themselves, OC-48 pricing has dropped so much over the years that it is now a popular connection for many businesses. This includes large hospital and medical center networks, video producers, content delivery networks, broadband Internet service providers, computer aided design firms, businesses with substantial e-commerce activities, popular websites, and heavy users of cloud computing.

Cloud computing is something of a two-edged sword. The advantages include fast scaling of services up and down as your needs change, high reliability, and the ability to empty local data centers to avoid ongoing capital and operating expenses. What might get lost in the initial zeal to outsource to the cloud is how you connect with your new virtual data center located hundreds or thousands of miles away. All of a sudden, WAN connections that were perfectly adequate when most of the IT servers were still on the corporate campus are now sluggish and unresponsive.

If you want to maintain or regain that snappy performance that comes with high speed low latency dedicated private line connections, you’ll need to upgrade your connections between your headquarters and your cloud services providers. OC-48 fiber optic bandwidth may be just the ticket. At two and a half times Gigabit Ethernet bandwidth, you’ll have the capacity you need to avoid network congestion. With a protected service and SLA (service level agreement), you’ll have the reliable service you need for critical business operations. Finally, with recent price reductions from competitive service providers, you can now afford a level of service that previously seemed out of reach.

Have the requirements of your business increased because of business automation, new technologies such as video transport, or a move to the cloud? This is a good time to get a new set of lease prices for both Carrier Ethernet and SONET fiber optic services. High bandwidth circuits, such as OC-48, are now more affordable than ever before.

What is Ethernet Service?

Carrier Ethernet services for business are becoming more and more popular. If you’ve been hearing about Ethernet service and wondering if it makes sense for your company, here’s what it’s all about.

Ethernet is the most popular LAN protocol by far. It’s hard to remember that not that many years ago there were all sorts of competing network protocols. Now switched Ethernet is almost universal. Something similar is underway with telecom services. We’re in the process of changing over from switched circuit technologies popularized by a century of telephone development to packet switched networks more compatible with computing devices. As you might suspect, Ethernet is making its bid to become the universal protocol of metropolitan and long haul networks.

Ethernet originated at Xerox PARC as a short distance communications technology to interconnect computing equipment. It was intended for use within an office or building. Communication farther than this required interface to telecom technologies, such as T-Carrier, SONET and Frame Relay.

Over the years, Ethernet has been extended and improved with the introduction of switching to eliminate the problem of collisions and fiber optics to increase network speeds. What has remained the same until recently is that connection to the outside world required conversion to a different set of protocols and back again at the other end. This is the last frontier of Ethernet networking that is now being addressed by Carrier Ethernet.

What is Carrier Ethernet? It’s the same as Ethernet, only extended to work over long distances on a telecommunications network. Carrier Ethernet standards have been developed by the Metro Ethernet Forum (MEF), an industry standards body. By introducing MEF compliant Ethernet services, carriers can be assured that their services will work with readily available customer and provider interface equipment and that network providers will be able to exchange traffic. They do that through an Ethernet Network to Network Interface (E-NNI).

Two of the most popular Ethernet services are E-Line or Ethernet Line Service and E-LAN or Ethernet LAN service. E-Line is a point to point dedicated line service that replaces traditional private lines such as T1, DS3 and OC-3. One end of the line can be connected to an Internet Service Provider give you Ethernet Internet service. In addition, E-LAN offers a many to many or meshed connection so that numerous business locations can be tied together on one large Ethernet network.

How about bandwidth? There are two physical layer options available. They are Ethernet over Copper (EoC) and Ethernet over Fiber (EoF). Ethernet over Copper is a direct T1 line replacement. It uses the same twisted pair copper telco wiring that T1 is provisioned over. Multiple pairs are employed to increase line speed. Popular EoC speeds are 2 Mbps, 3 Mbps, 5 Mbps, 10 Mbps 15 Mbps and 20 Mbps. Copper based Ethernet is distance sensitive, so the closer you are to the central office, the higher speed you can obtain. It’s not uncommon to get 25 Mbps, 50 Mbps, 100 Mbps or higher bandwidths for connections under a mile.

Ethernet over FIber picks up where Ethernet over Copper leaves off. Bandwidths from 10 Mbps to 10 Gbps are readily available, meeting the needs of just about any business.

In addition to easy interfacing and options such as E-LAN, a major draw of Carrier Ethernet services is their reduced cost. It’s not uncommon to get twice the bandwidth for the same money with Ethernet versus other telecom services. Also, that bandwidth is more easily scalable. The carrier equipment design makes it easy and fast to increase and decrease bandwidth as needed, up to the maximum speed of the installed port.

Are you interested in what Carrier Ethernet can do to support your business? If so, get instant online pricing for Ethernet services up to 1 Gbps and prompt quotes for other services to 10 Gbps.

Cloud Hosting Providers For Converged Networks

Cloud computing services are growing geometrically. If you haven’t gotten on-board yet, it’s probably because you aren’t convinced of the cost savings, security or the ability of the cloud to cover all bases for your IT needs. That picture is changing rapidly. Let’s take a snapshot of what’s available now for SMB users.

When we think of cloud computing, the picture that comes to mind is one of a giant brain in the sky that runs operations for hundreds or thousands of companies. That’s the approach that gets all the press, but it’s far from the entirety of the market. Indeed, there are many other providers out there who can deliver the virtual services you need on a less grand scale. You may not be able to get everything from one service provider, but the building blocks are out there to handle your voice and data needs.

That’s important, because enterprise VoIP solutions are driving a trend toward converged networks. If you only consider moving traditional data center servers to the cloud, you’ll be missing a big piece of the puzzle. The other trend that’s important is fixed mobile convergence that integrates cell phones into your telecom infrastructure. Mobility can be the link that makes or breaks your productivity in the future.

The foundation of cloud computing is cloud hosting that incorporates Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Cloud infrastructure is virtualization on steroids. IT departments have found that virtualizing servers ups the efficiency of the physical server hardware. What cloud computing does is greatly expand the virtualization to include huge racks of high performance servers plus storage and bandwidth. It differs from the virtualization that you would do yourself or the virtual servers you’d rent from a colocation center in that it is sold incrementally on-demand. You pay by the minute, by the hour or by the number of CPU cycles used.

Another characteristic of cloud hosting is that it is highly elastic or scalable. If you start to run out of capacity, you simply order up more virtual servers. The cloud operating system takes care of how these resources work in concert to provide the capacity you need. At no point do you have to purchase, install or maintain any equipment. The cloud service provider takes care of this with a 24/7 technical staff.

There are actually three types of clouds to choose from. The one that first comes to mind is the public cloud that serves many users simultaneously. You gain access via a private line or dedicated Internet service. Companies that have highly sensitive applications, unique requirements or simply want more control go with a private cloud. That is a similar infrastructure to the public cloud but on a scale suitable for one company. The hybrid cloud is a combination of the two. Public facing or non-critical applications run on the public cloud, while a separate private cloud handles very sensitive applications.

While cloud computing is thought of a data processing service, there is also a voice cloud known as cloud communications or hosted PBX. In this case, the computing resources are specific to telephony needs and the connectivity is by SIP trunk from your location and to the public switched telephone network from the provider. You no longer need a PBX phone system in-house or any telephone trunk lines. What you have is SIP telephones connected to your network and a converged SIP trunk from your business location or locations to the service provider. Some hosted PBX systems integrate cell phones into the system so that you have the same capabilities while mobile as at your desk.

Some of the cloud services you can readily get include cloud hosting, hosted PBX, unified communications, enterprise cloud security, private/public clouds, cloud storage, hosted Exchange, SharePoint, disaster recovery, anti-spam and anti-virus, hosted firewalls, and dedicated cloud access connections.

Are you feeling that you may be missing out on productivity improvements, cost savings, agility of scaling your business, or advanced features available in the cloud? This would be a good time to explore options with multiple cloud hosting providers. You can start small and grow or make a step-change relocation to the cloud, depending on what works best for your company.

DS3 and Fractional DS3 Broadband

In the quest to upgrade bandwidth, companies have generally turned to DS3 bandwidth service. Here is what DS3 is all about and the different technologies used to provide DS3 and similar mid-level bandwidth services.

DS3 stands for Digital Signal 3, a standardized switched circuit TDM telecom service. As a refresher, DS0 is the basic building block at 64 Kbps. That’s one channel of digitized telephone call. DS1 is a bundle of 24 DS0 channels at 1.5 Mbps. You are probably more familiar with its implementation as a line service called T1. DS3 is the next step up at 45 Mbps. It’s a bundle of 672 DS0 channels as a large telephone trunk or 28 T1 lines multiplexed together for transport. When you order a T3 line, you are getting the line service implementation of DS3.

Even though DS1 and DS3 were originally conceived as telephone company technologies, they are more often used to transport data packets today. That includes private point to point lines and dedicated Internet connections. In these applications, the entire payload is used to transport data packets.

A full DS3 circuit will give you 45 Mbps bandwidth in both the upload and download directions. This is the most common service ordered and is readily available nationwide. You’ll need an interface card for your router to connect to a DS3 termination. There are two interconnect cables, one for transmit (upload) and one for receive (download). They are 75 ohm coax, similar to what you’ll find for Cable TV connections, although the specified cable type is Bellcore 734 or 735 for this application. The connectors are type BNC. You’ll find these on the router interface card. There may be more than one pair if the router can handle multiple DS3 connections.

At this point, you might be imagining coaxial cables stretched from your building back to the telephone central office, like the twisted pairs used for T1 and multi-line telephone service. In practice, the coaxial connection is only used for short distances. The DS3 bandwidth itself is most often delivered over a SONET fiber optic cable, where it is demultiplexed and dropped off at your premises.

DS3 bandwidth may be higher than you require. There’s a big gap between T1 line bandwidth at 1.5 Mbps and DS3 at 45 Mbps. Companies often begin scaling up their bandwidth by bonding multiple T1 lines to double or triple the individual line bandwidth. This works up to about 10 or 12 Mbps in most cases. Let’s say you only need 20 or 30 Mbps right now. What do you do?

One option is to order fractional DS3 service. A full DS3 interface is installed, but the line bandwidth is limited to the fractional amount you order. That could be 15, 20 or 30 Mbps. You can possibly save money this way, but not necessarily. The reason is that full DS3 is more of a standard service that is readily available. The fractional services are a special order that may or may not be available in a particular location, depending on the service provider. In the end, it might make the most economic sense to get a full DS3 connection.

There are other technical options in this bandwidth range that compete with fractional and even full DS3. The most popular is Ethernet over Copper. This is a highly scalable service that competes with T1 at the 1.5, 2, and 3 Mbps levels. You can also get 10, 15, 20, 25, 30, 50, and sometimes even 100 Mbps Ethernet over Copper. This lets you match your budget more closely to the bandwidth you require. Ethernet over Copper (EoC) is often less expensive than either T1 or DS3 for similar bandwidths, although not as readily available as yet.

Downtown in major business districts you may also find fixed wireless bandwidth services. These often deliver DS3 bandwidths, but perhaps in an Ethernet protocol. Most of the time that’s what you want anyway, since you’ll be connecting to a LAN running Ethernet.

A final option isn’t DS3, but might give you a similar benefit for a lot less money. That’s business class Cable broadband. It is shared, not dedicated, and the bandwidth varies with the amount of user activity. Still, you can get up to 50 or 100 Mbps download with 5 or 10 Mbps upload service for about the price of a T1 line. You’ll need to have the cable passing by your business location for this service to be available. Otherwise the construction costs are prohibitive.

Are you in need of higher bandwidth to support your growing business, additional computerization or a move to cloud services? If so, get pricing and availability for DS3 and fractional DS3 services, plus related bandwidth services that may also meet your needs.

Gigabit Ethernet Port Scales WAN Bandwidth

When you are ready to make the move from copper to fiber bandwidth levels or upgrading an OC-3 SONET service, you are faced with a choice. What level of bandwidth do you install?

Why not give yourself flexibility for the future and the opportunity to pay only for what you need right now? This is what a Ethernet port strategy can do for you.

Scalability is a new idea in business telecom services. When you install a T1 line, it requires a very specific T1 interface that include a CSU/DSU circuit unique to the T1 line specifications. Upgrade to a T3 line (DS3 bandwidth) and you’ll find that you can’t just plug that T3 into your T1 router. The interface is completely different. Even the connecting cable is different. With DS3 you are looking at a pair of coaxial BNC connectors that don’t support any other service. Now, make yet another move on up to OC-3 service. Your router interfaces for T1 and T3 are no good. You need a fiber input to your router.

It doesn’t get any better when you start moving up the fiber optic hierarchy. You can’t just plug OC-12 or OC-48 into an OC-3 port and have everything spring to life. They are different services requiring modifications. You’ll likely need a new interface card and programming changes to your router. If you have a managed router, that probably means a truck roll to your premises to swap out the CPE (Customer Premises Equipment).

In the back of your mind, you must suspect it doesn’t have to be this way. Those new PCs have NICs (Network Interface Cards) labeled 10/100/1000 Mbps. That means that you can plug them into any LAN running at up to 1 Gbps and they’ll work just find. Even the connector takes the same RJ-45 patch cord. Wouldn’t that approach be far superior for WAN connections too?

This is the beauty of Carrier Ethernet, which includes Metro Ethernet, MPLS network access and long haul point to point connections. Ethernet beyond the LAN has been designed to be as flexible as Ethernet on the LAN.

One of Ethernet’s best features as a bandwidth service is ease of scaling. If you are running 50 Mbps service and find your needs have increased so that you now need 100 Mbps, you can just call up your service provider and request an upgrade. In a matter of hours or a day or two at the most, your WAN network speed will double. In that time, no one has knocked on the door with a new router under their arm. In fact, you haven’t seen anyone from the service provider. It was all done over the phone.

There is a trick to making this work. The magic is all in the installed Ethernet port. When you order Ethernet service, make sure that you have a port installed that will support the highest bandwidth you reasonably expect to be ordering down the road. Most ports are the standard Ethernet speeds of 10 Mbps, 100 Mbps and 1,000 Mbps. It’s also possible to get a 10,000 Mbps or 10 GigE port with a suitably fast managed router if your needs are that high.

With Ethernet over Copper, you are probably looking at a 100 Mbps Ethernet port at most. Be sure you know just what your maximum speed will be, because EoC is distance limited and requires more copper pairs as speed increases. Ask what bandwidth your installation will support compared to what you are ordering initially.

With Ethernet over Fiber, it likely makes sense to install a Gigabit Ethernet port. The fiber itself has more capacity that you are ever likely to employ. The speed of the port will be the limiting factor, along with the capability of the carrier’s equipment that feeds that port. Once again, it is smart to plan for the future but buy for today. Get the bandwidth you need now, but be sure that the system is engineered to allow for fast and easy upgrades as you need them. That will be especially handy if you get hit with a sudden increase in traffic or a need to support massive amounts of video or enormous file transfers that you didn’t anticipate.

Are you ready for a bandwidth upgrade, but unsure of what commitment to make? Give yourself some breathing room with a Gigabit Ethernet port and the ability to scale up your bandwidth as needed. Get prices and availability of Ethernet ports and line speeds now.

Level 3 Network Connections Into Mexico

If you do business in Mexico or are a multi-national company with a strong presence in Mexico, Level 3 Communications has good news for you. They’ve launched a major initiative to bring high bandwidth packet network services to business locations within Mexico.

Level 3 sees a business opportunity in Mexico that may be missed by carriers other than the incumbent, Telemex. it helps greatly that Level 3 recently acquired international bandwidth competitor Global Crossing, which already had significant network connectivity in Latin America. One of those assets is a 3,484 km fiber optic ring that connects Monterrey, Mexico City, Mazatlan and Guadalajara. From there it connects to the Pan-American Crossing submarine cable that runs from South America and Central America to the United States. There’s another connection at Tijuana, with a landing at Grover Beach near San Luis Obispo to connect to the California backbone and trans-Pacific submarine cables.

The Mexico ring is capable of providing Terabits per second of bandwidth capacity for transporting voice, data and multimedia services. Among the network services that Level 3 is now offering in Mexico are EtherSphere, Managed IP VPN, High Speed IP, Dedicated Internet Access, Wavelength Services and Private Line Service.

EtherSphere is a worldwide Ethernet-based WAN service, connecting Ethernet transport services from 150 locations that support 26 cities around the globe. EtherSphere offers Virtual Private LAN services (VPLS) specifically intended for companies with geographically dispersed business locations. VPLS is a mesh network technology running on the Level 3 MPLS (Multi Protocol Label Switching) core network. It’s also called Transparent LAN Service. The idea is to connect multiple Ethernet LANs together as if they are one bridged network serving all locations.

EtherSphere is a comprehensive VPLS service that supports six Classes of Services to prioritize traffic and enable network convergence on a large scale. You can easily scale bandwidth in various increments between 1 Mbps and 2 Gbps, although the system does support bandwidth above 2 Gbps. You have a choice of service types through the network that include multipoint to multipoint (mesh), point to multipoint (hub and spoke) and point to point connectivity similar to Ethernet private lines.

Level 3’s IP VPN service runs on their converged MPLS backbone rather than the public Internet. This gives you six-level Class of Service (CoS) for high performance voice and video transport as well as data connections. Level 3 owns more than 100,000 fiber miles connecting 450 markets in more than 45 countries. Your last mile connection can be anything from T1 through Gigabit Ethernet.

Level 3 is one of the world’s most connected Internet Service Providers. Their Dedicated Internet Access offers IP port speeds from DS-1 (1.5 Mbps) to 10 Gigabit Ethernet. High bandwidth users can opt for High Speed IP (HSIP), a dedicated wholesale high speed Internet service.

For the ultimate in high bandwidth service, Level 3 Wavelength service offers high performance, low latency fiber optic wavelength services over their high speed DWDM network. Available speeds are GigE, 2.5 Gbps, 10 Gbps, 10 GigE and 40 Gbps. You can order both protected and unprotected point to point configurations. Native Fiber Channel and FICON protocols are supported.

Level 3 Private Line services are available worldwide in over 45 countries. These connections are delivered over proven SONET and SDH architectures that are protocol independent. You can transport IP, voice, data and video as Layer 2 or Layer 3 traffic.

Do you have connectivity needs that include service to locations within Mexico or other international destinations from the United States? If so, get prices, features and availability for International fiber optic network services.

RAZR Reincarnation

When the original Motorola RAZR smartphone appeared on the market, it caused quite a stir. You might say it was the iPhone of its time. When cell phones were chunky little flip blobs or hefty candy bars, the RAZR boasted the thinest profile at the time. It was an amazing half-inch thick. How could they possibly get all that technology in that also revolutionary aircraft aluminum case?

Now there’s a new RAZR phone with far more advanced technology and it’s even thinner, measuring a scant 0.3 inches or 7.1 mm. Instead of machined aluminum, the case is now laser-cut KEVLAR with Corning Gorilla Glass to protect the screen. There’s even a splash guard coating to shield the electronics from water attacks, just in case you are partial to Pina Coladas and getting caught in the rain. Meet the DROID RAZR by Motorola for Verizon Wireless.

What else is new in the RAZR technology upgrade? First of all, network connectivity. This is a 4G LTE Smartphone. That means blazing speed, more like a home or office Internet connection than what you’d expect from the cellular networks. If you wander out of 4G coverage, the RAZR will revert to 3G. You can choose to connect to a WiFi hotspot or be the hotspot. Share your 4G LTE Internet connection with up to 8 other WiFi enabled devices. On 3G, it supports 5 WiFi devices.

There’s a speedy 1.2 GHz dual core processor inside, with 1 GB of RAM. Storage memory is 16 GB on board with support for up to 32 GB on plug-in cards. It runs Google’s Android OS 2.3 Gingerbread operating system with the Motorola Application Platform. Your hardwired interface connections include a micro USB port and a micro HDMI-1080p port that can be run in mirror mode to your HDTV or monitor.

The DROID RAZR screen is a 4.3 inch Super AMOLED advanced display that serves up hyper-vibrant colors and smooth action for movies and TV shows. You can stream from Netflix or download those movies from the Android Market. Another cool feature is MotoCast, a free app that lets you securely access files that are stored on your desktop computer. No need to upload to a third-party cloud. You can stream from where your media already exists.

That high resolution display is matched to an 8 Megapixel rear facing camera that can record 1080p HD video. Don’t worry about being a little shaky as you capture images. The DROID RAZR has image stabilization included to smooth out the scenes. The audio that accompanies the video has selectable modes that include stereo, wind reduction, concert and more. There’s a dual mic system onboard so that you can take calls even in noisy environments and still be heard clearly. A second camera faces front for video conferencing. This one has 1.3 Megapixels, which used to be a good spec for the main camera. Time marches on. You can capture 720p HD video with the front facing imager.

Here’s your chance to get this advanced personal and business phone at a special online price. Don’t plunk down too much green at a carrier store or big-box retailer until you check out the Special Deal on DROID RAZR by Motorola for Verizon Wireless. Clearly, it’s time to upgrade to a much sharper razor phone.

Hosted VoIP Can Improve Telephone Reliability

Many mid-size and even large companies insist on maintaining their own in-house telephone systems in the belief that it’s the only way to ensure reliable communications. Is this really true, or just one of those long held beliefs that need to be re-examined?

There’s been a major game changer introduced into the telephone services industry recently. It’s the rise of hosted PBX or HPBX. You’ll also hear it called hosted VoIP or communications in the cloud. Like everything else “in the cloud,” this is truly a revolution in technology. In a decade or two, we’ll look back and wonder why we didn’t always do it this way.

“Cloud, schmoud,” you say? I can see how you might feel that way, especially if you’ve been burned by a poor implementation of VoIP technology. VoIP isn’t a particular product or even standardized methodology. It’s a general class of voice communication based on packet switched network technology. VoIP runs the gamut from software running on a laptop computer at the coffee shop, to dongles that let you plug your telephone into a PC, to broadband phone that shares an Internet connection, all the way up to enterprise and even carrier level solutions that are indistinguishable from traditional phone systems to the caller.

What successful enterprise implementers of VoIP telephony know that others don’t realize is that you need a carefully engineered network from the telephone handset to the service provider to protect fragile voice packets from being crushed by more numerous and robust data packets. In most cases, that means stay off the Internet except when you absolutely have to in order to include a remote worker or someone traveling. One reason is that the Internet does not support Class of Service controls to ensure the integrity of voice packets. Other parameters, such as bandwidth, latency, jitter, packet loss and out of sequence packet arrivals are uncontrollable on the public Internet. All of these are readily managed on private lines, MPLS networks and SIP trunks.

With the connectivity issue solved, there is still the issue of reliability. Won’t an in-house hardware solution that’s been proven over years of operation be inherently more reliable than “something out there, somewhere?” Not when you realize that the “something” you are referring to is the latest high quality servers set up for redundant protection with multiple levels of backup power and complete environmental controls. Like everything else in the cloud, there is a lot of virtualization involved so that resources are available in depth and instantly scalable.

The hosted solutions provider absolutely must provide high quality service or they’ll go out of business. After all, this is either a major part of their business or all of it. They almost always have technical staff on duty 24/7 and keep up with maintenance activities. How about at your company?

This is where the superiority of in-house PBX starts to become suspect. First of all, is your system really that rock solid? Parts never fail? The power never glitches or goes completely off? You may have duplicated the security, environmental control and power backup of a SAS 70 Type II data center, especially if you need this facility for your IT equipment. On the other hand, if your PBX is simply sitting in a “telephone closet” or maintenance room where the phone and data lines come in, you may not be all that well protected against disasters.

How about the age of that machine? We know that computers go obsolete almost before they are unboxed. PBX phone systems aren’t quite that bad, but they do start to degrade as the years go by. At some point, it’s hard to find replacement parts or even someone knowledgeable to maintain the system and make repairs. New features are introduced into the telephony marketplace, but you can’t take advantage of them. Your system is just a bit too old to be upgraded. This is how obsolescence begins. Pretty soon, you’re patching together a dinosaur that should have been hit by a meteor years ago.

It is being recognized that hosted VoIP solutions can be as reliable and even more reliable than in-housed PBX telephone systems. You need to pick a quality supplier and install highly reliable network connections to gain the benefits of high reliability in the cloud. If you do that correctly, you’ll enjoy reliable communications, access to the latest productivity features, integration with mobile devices, and the cost savings of paying by the month only for what you need.

Has this discussion piqued your interest on how hosted solutions might be a better choice than what you have now? If so, get pricing and features for Hosted VoIP solutions that meet your particular requirements. See if you can’t get more value for the same or less cost than your current business telephone system.

Pricing Slashed For Michigan 100 Mbps Business Internet

Businesses in Michigan, like businesses everywhere, are hurting for bandwidth. Between the increased use of video, business automation, and everything moving to the cloud, those aging T1 lines are starting to grind to a halt under the load. Bonded T1 will only take you so far. After that, it’s time to face an order of magnitude price jump to get into fiber optic services. Well, that’s how it was. Now there’s another option that offers fiber bandwidth at T1 prices. Is this for real?

Comcast Business Class 100 Mbps / 10 Mbps service is definitely for real and the answer to a profit squeezed company’s prayers. All of a sudden, that big constriction at the LAN/WAN interface is gone. Files move fast. Web pages pop before your eyes. Email? You could drown in all the email that can flood in at 100 Mbps.

So, how do you get OC-3 or Fast Ethernet bandwidth levels without the high cost of fiber? What you tap into is HFC or Hybrid Fiber Coax. That’s the technical name for the finely tuned network that Comcast has deployed in their vast service area. There are two types of transport technologies that are welded together in HFC. Hence, the hybrid designation. The core of the network is a robust fiber optic backbone that is worthy of any major carrier. The access connections are coaxial copper cable. You know it as TV cable. What you may not realize is just how much bandwidth that coax connection supports.

Cable TV companies started using coaxial cable back when they were little more than enormous master antennas. The same coax that connects from your outdoor TV antenna to the back of your TV set can also bring in a much larger set of channels from your Cable company. Decades ago, it was all analog on Cable and over the air. Now it’s all digital. The RF spectrum on the cable is still channelized, with one digital TV station per slot. There are a lot of TV channels to choose from, but they don’t use all the possible channels that the cable can support. Some of those channels have been set aside for broadband or telephone services.

Besides the analog to digital transition, the other thing that’s changed with Cable operations is deployment of a fiber optic backbone to interconnect the multiple systems that the Cable operator owns and bring all the programming content into the neighborhood. This fiber network has far greater capacity than the old style large diameter coaxial distribution cable.

If fiber is so great, then why not run it directly to homes and businesses? Someday, that’s what will probably happen. Right now, the economics say no. Fiber termination equipment is expensive. Trenching a roll of plastic coated copper coax and connecting it to a wall outlet is cheap. With the ability to deliver television, broadband Internet access and telephone on that inexpensive little line, who wants to pony up for fiber?

You don’t or you’d already have installed SONET OC-3, OC-12, OC-48 or Ethernet over Fiber service for your business. Either the construction cost is a show stopper or the monthly lease fees are more than your budget can handle. Now you have another choice with Comcast’s 100 Mbps business broadband. It’s inexpensive and it can be installed quickly for any business that the Cable infrastructure passes.

What makes this service so affordable? For one thing, the cost of the network is spread over thousands of television and broadband customers. For another, this is not a true telecom service like SONET or Ethernet. Those services are symmetrical in that they have the same upload and download speeds. If you need 100 Mbps in both directions, Comcast’s offering won’t work for you. It’s specified at up to 100 Mbps download and up to 10 Mbps upload. That configuration is exactly what you need for general Internet access, where uploads are few and small but downloads are frequent and massive.

Also note that Cable is shared and not dedicated bandwidth. An OC-3 fiber connection gives you 155 Mbps all to yourself. Whatever you don’t use sits idle until you need it. You are sharing the Cable bandwidth availability with other users so that the network is always in use. This sharing also means that your bandwidth will vary throughout the day depending on what everyone is doing online. Does it matter? It may or may not, depending on how important it is to you to have that 100 Mbps at your disposal at all times.

Finally, there are no service level agreements like you have with T1 lines and the like. This is a “best effort” information service that is offered as-is. Even so, Comcast takes its network seriously and works to keep it as reliable as possible. If you’ve used home Cable broadband and been happy with the way it performed, then you’ll probably be happy with the bigger, faster Business Class service that gives all your employees a similar level of service while accessing the Internet on their desktop computers.

Are you a Michigan business owner or IT manager who’s anxious for high speed Internet access at a very affordable price? Check into prices and availability for 100 Mbps Internet options at your location. Note that Comcast and other fast Internet services are also available for locations other than Michigan.

Vyvx and Genesis Offer Worldwide Video Transport

If you are involved in video production, distribution, news reporting or TV sportscasting, you have an immediate and ongoing need for video transport services. Satellites have long been used for this purpose, but worldwide fiber optic networks have benefits that include almost unlimited bandwidth, low latency and availability for many popular venues. The merger of Level 3 and Global Crossing has combined their video transport operations into an impressive array of service options.

Level 3’s Emmy Award winning video service is called Vyvx. They offer broadcast fiber services, managed video network services, teleport and satellite services and venue services. Their venue service, called VenueNet, offers dedicated access points at every major league stadium in the US. In addition to accessing the Vyvx fiber optic network, Level 3 provides high quality video encoding, Internet, telephone access and dedicated support for each venue.

The heart of the Vyvx system is a IP MPLS network with extensive reach. What MPLS brings to the table is inherent VPN security, the ability to reroute video connections on the fly if a fault occurs in the network, and rapid set up and tear down of video connections. You can plan ahead to book the service you need or get a connection at the last minute through the Vyvx 24/7 booking center. This is more difficult to do with limited bandwidth satellite services and unheard of with dedicated point to point fiber connections over traditional switched circuit telecom networks.

Within the last year, Level 3 has added uncompressed high definition video transport services between Los Angeles, Washington D.C. and New York City at 1.5 and 3.0 Gigabits per second. This offers video producers and broadcasters the opportunity to deliver live video feeds in their native, pristine form without any compression.

Another Vyvx service is Managed Video Network Service (MVNS). This is a fully managed distribution system that provides both fiber optic connectivity and the necessary equipment. With MVNS, you can distribute video feeds to multiple destinations using a web-based booking system. These feeds can be broadcasts or prerecorded content.

With the acquisition of Global Crossing, Level 3 has picked up Global Crossing’s Genesis Solutions, a formerly competing video transport service. Genesis offers global HD video over IP transmission, portable bandwidth that you can book as you need it, and point to multipoint access that can be set up immediately.

Global Crossing’s converged IP network connects 700 cities in 70 countries worldwide. The Genesis Solutions uses that network to offer specialized managed video services with compressed and uncompressed transmission options. Dedicated bandwidth is available in any increment between 2 Mbps and 270 Mbps. MPEG 2/4 compression equipment is available for encoding, decoding transcoding and compression to deliver the desired bit rate and format needed.

As you can see, there is a lot of compatibility between Level 3’s Vyvx and Global Crossing’s Genesis. The combination of the two networks adds capacity and extends the reach of the combined system to every major broadcast market in the world via fiber optic transmission. There are also eleven satellite teleports for those odd locations where fiber still doesn’t go.

Do you need full time or occasional video transport services for broadcast or program distribution? If so, don’t assume that the cost is prohibitive or that there isn’t the capacity available for the locations you have in mind. Level 3 Vyvx Solutions has both the capability and experience to handle whatever you need and whenever you need it. Check prices and options for video transport services now to confirm that your project will meet schedule and budget.

New York City Internet Infrastructure

When it comes to high bandwidth network services, you would expect New York City to be among the most infrastructure rich places in the world. You’d be right. One key hub in this infrastructure is the network colocation center at 60 Hudson Street in lower Manhattan. This is where Telx operates their flagship carrier hotel and network interconnection facility.

In a recent article in The Atlantic, Ben Mendelsohn discusses his short documentary, Bundled, Buried & Behind Closed Doors, which includes a tour of the Telx facility at 60 Hudson. You can watch it right here and get a fascinating view into the inner workings of network interconnections, like those at the heart of the Internet.



The Telx data center at 60 Hudson is their flagship colocation and interconnection facility. Within the walls of the old Western Union Building, Telx offers low-latency access to more than 400 carriers, financial exchanges, application providers, media and content providers, SaaS providers and other enterprises through a single connection. This is why companies that need high bandwidth, low latency connections choose to colocate at 60 Hudson or in another Telx facility. It’s hard to get much closer to your service provider than to be situated in the same building.

Cross connections are at the heart of the Telx colocation centers. This is nothing more than simple wired or fiber connections from a customer’s equipment rack, cabinet or cage to a passive interconnection panel in the interconnection space. The cross connect allows you to connect to any of the other services in the facility. If you change your mind or want connection to additional providers, it’s a simple matter of patching from your panel to theirs.

In addition to the passive cross connects, Telx also offers dynamic interconnections. They are a pioneer in Ethernet Exchange through a E-NNI or Ethernet Network to Network Interface. What this service does is allow Ethernet service providers to connect to each other through a standardized interface so that each provider extends the reach of their network. This is especially valuable for IP core networks which would otherwise have to first convert another protocol like SONET/SDH to achieve commonality with other networks.

In addition to 60 Hudson Street in New York City, Telx has another facility at 111 Eighth Avenue in NYC, two locations in New Jersey, two facilities in Chicago, two more in Dallas, plus colocation and interconnection centers in San Francisco, Atlanta, Miami, Phoenix, Charlotte, Los Angeles and Santa Clara. That’s 15 buildings spread out nationwide, with at least one close to your business location. They also have partnerships with Tata and Interxion for global locations.

If you have a need for high speed Internet access, cloud access, content delivery, low latency connections or other private line or network services, it is well worth your while to look into services and pricing for colocation and interconnection services from Telx and other premier service providers.

100 Mbps Internet for Business

DS3 Internet bandwidth at 45 Mbps has been the mainstay of many mid-size businesses. It is readily available and a substantial bandwidth increase over T1 or even bonded T1 lines. Now even DS3 bandwidth isn’t enough to keep up with many simultaneous video users or cloud service applications. It’s time to move on up to 100 Mbps Internet access.

The 100 Mbps service level is particularly significant because it precisely matches one of the standard Ethernet LAN speeds called “Fast” Ethernet. Most all NICs (Network Interface Cards) built into nearly everything from PCs to routers, switches and printers support 10/100 Mbps Ethernet. That’s the 10 Mbps and 100 Mbps network speeds. Newer NICs expand that to include Gigabit Ethernet or GigE with 10/100/1000 Mbps ports.

The point is that if your LAN is running at 100 Mbps and you connect to the Internet at some lower speed, you are going to experience a slowdown on anything to or from the Internet. At low network activity levels, you may not notice the difference. It’s when there are lots users doing lots of things simultaneously that the congestion occurs. The big choke point, more often than not, is the WAN or wide area network connection to the Internet.

Fortunately, 100 Mbps Internet service for businesses is more available and less expensive than ever before. Let’s take a look at the different technical approaches and their advantages or disadvantages.

The traditional 100 Mbps telecom service is OC-3, which actually runs at about 155 Mbps. This is a SONET fiber optic service offered by switched circuit telecom companies nationwide. OC-3 is a transport service that can carry anything from thousands of telephone calls to private point to point connections to dedicated Internet access. It’s also often used to deliver lower speed services, such as DS3. You probably don’t think of DS3 as a fiber optic service because your connection is through BNC connectors on small diameter coaxial cables. Still, it’s likely dropped off at your location using an add/drop multiplexer connected to a SONET fiber cable.

OC-3 has the advantage of being a well established and highly popular digital line service. It comes with an SLA or Service Level Agreement, standard in the telecom industry. Your bandwidth is both dedicated and symmetrical. Dedicated means that you don’t share that 155 Mbps with any other company or individual users. Whatever bandwidth you aren’t using at the moment sits there idling so that you always have the full 155 Mbps at your disposal. Symmetrical means that you have 155 Mbps in both the upload and download directions. Sometimes this is expressed as 155 x 155 Mbps Internet access.

Competing directly with OC-3 bandwidth is Carrier Ethernet. Fast Ethernet at 100 Mbps is an easy interface to your LAN. All you need to do is plug in a standard RJ-45 patch cable and your router has Internet access. There’s no need for fiber optic cabling and special interface cards like you have with OC-3 or a managed OC-3 router installed by the service provider. Like OC-3, 100 Mbps FAST Ethernet is both symmetrical and dedicated. It also comes with an SLA from the provider.

Fast Ethernet service is available over both fiber optic and twisted pair connections. In fairness, the Ethernet over Copper service at this speed is fairly distance limited so you’ll likely find it only in major metropolitan business districts. Slower speeds, say 10 or 20 Mbps, have a much greater range and are more readily available.

Ethernet over Fiber is similar to OC-3 with two important advantages. First, the cost per Mbps is often lower, even much lower than OC-3 where available. Another advantage is that Carrier Ethernet services are highly scalable. The next increment up from OC-3 is OC-12 at 622 Mbps. With Carrier Ethernet, you could go from 100 Mbps on up to 200, 500 or even 1,000 Mbps without an equipment change. The trick is to have a Gigabit Ethernet port installed initially. Then order the bandwidth you need today with the understanding that you can easily upgrade in the future when you need to.

A final option that is becoming more available is 100 Mbps Cable business broadband. This is a shared asymmetrical bandwidth service sold without service level agreements. It’s very similar to the Cable broadband you get at home, but with extra features such as static IP addresses and special customer support. Your 100 Mbps is in the download direction only. Upload speeds are on the order of 10 Mbps. This bandwidth is shared by many other users, so it varies all over the place even during business hours. Even so, you can’t beat the pricing which is similar to a T1 line. If all you need is casual Internet access for many employees and have a very limited budget, this could be the answer for you.

Are you ready to establish Business Internet service at a new location or upgrade from bonded T1 or DS3 to 100 Mbps or higher Internet access? If so, check 100 Mbps Internet pricing and availability for your business location. Complementary consulting is also available to help you sort through the options.
