SONET Rings To Support Ethernet

The hot bandwidth service these days is Carrier Ethernet. Everybody wants it once they see the cost advantage over the WAN connection they have now. The big question is can they get it?

In most cases, the answer is yes for a couple of reasons. First, new competitive carriers are rapidly building out their fiber optic core networks based on IP from the start. These networks are tailor made for Carrier Ethernet services. It’s relatively easy to get a point to point Ethernet connection between two distant business locations and use it to link their respective LANs. The result is one larger bridged LAN that enables all employees to be on essentially the same corporate network.

The other reason that Ethernet WAN services are so readily available is that established SONET fiber optic networks are being pressed into service to deliver Ethernet to the customer. This is known as Ethernet over SONET or EoS. The core of the network is still SONET, but operations at that level are invisible to you. As far as you are concerned, your connection is Ethernet all the way.

There’s no reason that SONET can’t transport Ethernet, ATM or other protocols. It was designed as a transport technology and has been adapted over the years to carry whatever traffic required hauling. The origins of SONET, like T-Carrier, are with the telephone industry. The name is an acronym for Synchronous Optical NETwork. Note the term synchronous. That tells you SONET is set up to be a highly synchronized network. The designed is based on multiplexing thousands of small channels called DS0s that each hold one telephone call. These DS0 building blocks can be combined to create T1 and T3 lines or SONET services such as OC-3, OC-12 and OC-48.

The beauty of synchronization for circuit switched architectures based on time division multiplexing is that everything is orchestrated so tightly and you can easily multiplex and demultiplex channels and higher level services. The device that does this is called an ADM or Add/Drop Multiplexer. An ADM can drop off a T1 line, DS3, OC3 or other service at your door from a much higher speed fiber line that carries traffic for many customers.

How does Ethernet squeeze into those tiny telephone channels? It takes some doing, considering that each DS0 carries exactly 64 Kbps. That’s about the speed of an old dial-up modem. What the industry has done is replace the telephone oriented channels with large concatenated frames and various mapping techniques to more efficiently carry Ethernet packets. SONET networks can now readily carry Ethernet services from standard 10 Mbps Ethernet to 100 Mbps Fast Ethernet, 1000 Mbps Gigabit Ethernet (GigE), and 10 Gigabit Ethernet (10GigE).

A feature of most SONET networks that makes them highly reliable is their twin ring design. Two separate fiber strands are used simultaneously. Each carries the same traffic, but in opposite directions. If a fault occurs in the working ring, the network switches over to the protection ring within 50 mSec. This self-healing property works best when the two rings are widely separated so that a single backhoe cut or equipment fault doesn’t take out both rings at once.

Ethernet over SONET and native IP networks are making Carrier Ethernet services of all speeds readily available for businesses looking to upgrade their bandwidth connections at reasonable costs.

Combine T1 Lines For Higher Speed

T1 lines have been popular with small and medium businesses for decades. They are highly reliable, private, dedicated bandwidth, and easy to come by. With fierce competition bringing down prices in recent years, what’s not to like? If only you could get T1 lines to run faster....

There’s a way to do that and still keep all the advantages of T1 line technology. The technique is called bonding. It’s an industry standard method of combining the bandwidth of multiple T1 lines so that they behave as a single much larger connection.

You can’t really hot-rod a single T1 line. The system was designed to be synchronized so that the line can be segmented into 24 separate telephone lines or multiplexed into higher bandwidth services. A T1 line runs at 1.5 Mbps and that’s that. What bonding does is let you bring in another T1 line and hook the two together for 3 Mbps.

Why upgrade in the first place? Bandwidth demands are increasing. You know that every few years you need to upgrade the processing power and RAM in your PCs to keep running efficiently with upgraded browsers and other applications. Expect the same to be true of your WAN connections. Whether it’s file transfers from point to point between business locations, Internet access or a connection to cloud services, you’ll need higher bandwidth to stay competitive.

T1 lines can be combined in larger groups to give you even more bandwidth. Bonding 3 T1s provides 4.5 Mbps, 4 T1 lines offer 6 Mbps, 5 bonded lines equal 7.5 Mbps, 6 T1s provide 9 Mbps, 7 T1 lines offer 10.5 Mbps and 8 bonded T1 lines get you to 12 Mbps. Eight line bonding is about as high as most carriers go. The cost of bonded T1 is equal to the price of a single T1 times the number of lines used. When you get past 8 T1s it is generally cheaper to move up to DS3 or even fiber optic connections.

How do you connect all these T1 lines coming into your facility? Your service provider will take care of that. They supply a managed router with multiple WAN Interface Cards (WIC) that handled the interface to each T1 line. The router then does the bonding in tandem with carrier equipment on the other end and delivers a single bandwidth port (RJ45) running at the higher bonded speed.

This is important. For bonding to work, you need to get all of your T1 lines from a single provider. If you try to mix and match vendors, they have no way of coordinating line operation and you just wind up with Individual T1 lines. You can do load balancing with your own routers or buy a bandwidth aggregation appliance to combine unrelated lines, but this is not true bonded T1.

Does any other service compete directly with bonded T1? Yes, Ethernet over Copper does something very similar. It bonds multiple twisted copper pair (up to 8 pair) to deliver a single bandwidth service from 2 Mbps to over 100 Mbps. The trick in delivering the higher bandwidths is a more sophisticated modulation scheme that is distance sensitive. The nearer you are to the central office, the higher the speed available. If available, you can probably get higher bandwidths and better prices than bonded T1 services. However, availability is generally limited to metropolitan areas at this time.

Get Your Building Fiber Lit For Free

There are some tremendous deals on fiber optic bandwidth these days. Many companies would dearly love to move up to Fast Ethernet at 100 Mbps, GigE at 1000 Mbps or even 10 Gigabit Ethernet. The one problem is that their building isn’t lit for fiber optic service yet. When they see the construction cost quote to bring in the fiber, the up-front cost is just too high in this economic environment. But, what if you could get your building fiber lit for free? Would that change your bandwidth plans?

It’s absolutely possible that you can upgrade to high speed fiber services without having to pay construction costs. The little known secret is that some competitive carriers see such an opportunity in the demand for higher bandwidth services that they are willing to put up money for construction costs themselves. One carrier is willing to build up to 1,500 feet of fiber if that’s what it takes to get you on their network.

Oh, but do you have to pay extra in monthly lease fees to get the free hookup? No way. In fact, you may be surprised at how much fiber lease costs have come down lately. If you haven’t gone out for quotes in a few years, you are dealing with pricing so obsolete that it’s a joke. You need to get a new set of competitive quotes right now.

Everything is pulling in the same direction now for fiber optic bandwidth. First, demand is increasing by leaps and bounds due to the increased use of video in business, including video conferencing. Business automation is making employees more productive than ever, but it comes with an increased need for bandwidth to connect to providers. Cloud services are adding additional pressure on WAN connections to provide response times similar to what you experience with a local data center.

We normally think that when something is in high demand, the price goes up not down. Just the opposite is happening in the network bandwidth market. Why? Increased demand has encouraged competitive carriers to build-out their regional, national and international fiber networks. Many have embraced new service options, such as MPLS networks and Carrier Ethernet. What every competitive carrier wants is more customers to connect to their massive core networks. That means getting more buildings on-net.

What on-net means is that your particular building is on the network of a particular fiber optic carrier. If you are on-net, that carrier has fiber strands coming into your building and terminating in equipment that the carrier provides. From there, they can connect you and other tenants in the building, if there are any, to whatever speed and format service you require.

Many carriers don’t want the aggravation of butting heads with competitors in the same building. Instead, they’ll try to find nearby buildings that aren’t already lit and get in there first. Once established, it’s easy for them to sell and keep customers. Fiber bandwidth is nearly unlimited, so scaling services up and down is no trouble at all. Do you need to move up from 100 Mbps to 500 Mbps? You might be able to make that happen in a matter of hours if you already have a Gigabit Ethernet port installed. Just call the carrier and tell them you want a speed increase. They can likely do that without having to change out any equipment at all.

It’s a real land-rush situation for competitive carriers, since something like 12% of business locations are already lit for fiber service. You are in the majority if you don’t already have fiber optic bandwidth. But if you are close enough to a carrier point of presence, you may be able to get those fiber services cheaper than you ever thought possible. Why not see what opportunities are available and then decide how much you can upgrade and still stay within your budget? Get instant online fiber optic prices for Carrier Ethernet from 10 Mbps to 1 Gbps now. Other services will be quoted promptly, including construction costs if any. You may be in a better spot to get affordable fiber service than you ever thought possible.

Ethernet Internet Service Access For Business

Internet access has become key to doing business, both on the Web and for bricks and mortar operations. The Internet has become ubiquitous in connecting to customers, suppliers, remote workers and even between company locations. So, is business Internet the same as what consumers use or are there differences?

There are various characteristics of Internet service access you can choose, including dedicated or shared, symmetrical or asymmetrical, wired or wireless, copper or fiber, bandwidth level and cost. One of the newest and most cost effective services that meets the needs of many business locations is Ethernet Internet service. Can it be what you are looking for? Why not get an instant online price quote and compare with what you have now?



These Ethernet Internet service access quotes are for business locations only, not residences. At the low end of the price spectrum are business Cable broadband connections which are shared bandwidth and asymmetrical. They give you a high maximum download speed, but that speed varies all over the place since the bandwidth is shared among many users. Download speeds are 10x or so upload speeds, specifically intended for Web surfing, email, and watching online video.

Ethernet over Copper and Ethernet over Fiber Internet Service works more like traditional telecom lines. The bandwidth is symmetrical so that upload and download speeds are the same. You also get the bandwidth you order since it is dedicated to your use only and doesn’t depend on what other users are doing.

Ethernet over Copper uses the same twisted pair copper telco wiring that you use now for multi-line telephone and T1 lines. That’s makes construction costs negligible in many cases. Line speeds are available from 1 Mbps on up to 100 Mbps or more, depending on how far you are from the central office where your wiring connects. Up to 8 copper pair may be used to deliver the higher bandwidths.

Ethernet over Fiber requires a fiber optic line, but it delivers much higher bandwidths. With EoF, you can easily get Fast Ethernet at 100 Mbps and Gigabit Ethernet at 1000 Mbps. In some cases 10GigE is also available for large enterprise applications.

Can you get twice the bandwidth for the same money as you pay now by switching to Ethernet Internet Service for business? Check the speeds, prices and availability and compare with your current Internet service.

A Dedicated Line Between Offices

Many companies have two offices that they would like to link. These offices may be in the same city, across the country or even in different countries. What options are available to do this and what services can you get?

The traditional telecom services link between offices is the dedicated private line. T1 lines have been long used for this purpose because they are almost universally available and often the lowest cost solution. A point to point T1 data line will give you 1.5 Mbps of symmetrical bandwidth. That means 1.5 Mbps upload and 1.5 Mbps download. Symmetrical bandwidth is important when used to link business locations because you’ll have similar traffic levels going in both directions. That differs from the Internet where downloading predominates.

Two other characteristics of T1 lines are important to consider. One is that this is a private line. It’s like having a pair of wires connected at one building and the opposite end of the wires connected at the other building. In fact, for local T1 lines that may be close to the way it is wired up. Over longer distances, your T1 service will probably be multiplexed on a higher bandwidth connection, likely a fiber optic network, for the long haul portion of the interconnection. Regardless, you have a private service that is difficult for anyone to intercept. If you want to ensure the ultimate in privacy, you have the option to encrypt your transmissions on that line.

The other important characteristic of T1 lines is that the bandwidth is dedicated to your usage. You can load it up with two-way traffic 24/7 or just use it when you want to transfer a file. Whatever doesn’t get used just sits there waiting for you. You’ll never run into the situation where your service slows down because some other company is downloading HD videos from the Internet. This also means that there are no usage restrictions. Your T1 line can be used lightly or continuously and your bill at the end of the month will be the same.

T1 lines are available in both data and voice configurations. The voice configuration, called T1 telephone, can transport 24 separate phone conversations. A variation, T1 PRI or ISDN PRI transports 23 phone lines plus a switching and information channel used to provide Caller ID.

What if you need more bandwidth? The next step up with traditional telecom services is DS3 at 45 Mbps, followed by SONET fiber optic including OC-3 at 155 Mbps, OC-12 at 622 Mbps, OC-48 at 2.5 Gbps and OC-192 at 10 Gbps.

You also have the choice of Ethernet line services from typically 10 Mbps on up to 10 Gbps as point to point dedicated connections. Ethernet tends to be lower in cost than traditional services and more scalable. In other words, it’s easier to increase line speed with Ethernet than with T-carrier or SONET.

Another option to link offices, especially over long distances like coast to coast or internationally, is MPLS networking. MPLS networks are highly secure, well engineered to provide committed bandwidth levels, and reasonably priced. It may well be cheaper to order a last mile connection at each end and let the MPLS network handle the long haul than specify a dedicated point to point line service. You’ll get similar performance either way.

Are you looking to establish a dedicated line between offices, perhaps with one of them overseas? Compare options and prices online for T1, DS3 and Ethernet up to 1 Gbps. Note that US to international destination connections will require some manual effort to price, with quotes delivered promptly to your specifications.

IP WAN over MPLS Advantages

When we think of IP wide area networks, the first thing that comes to mind is the Internet. While the Internet does have almost universal connectivity and modest cost to access, there are some serious issues when it comes to business applications. Bandwidth, latency, jitter and packet loss have no guarantees and few expectations. Security is a joke. But aren’t other methods to interconnect business locations costly and hard to manage?

It is possible to set up a private IP network that lets you use your familiar IP addressing schemes and avoid encryption, firewalls, tunnels, and additional hardware. You’ll gain a performance advantage compared to using VPN techniques over the Internet and save yourself the administrative headaches of trying to manage a WAN with inherently indeterminate characteristics. Who offers something like this? It’s TelePacific, one of the nation’s largest competitive carriers.

TelePacific’s 1Net is an IP VPN running on a private MPLS network, not the Internet. Since MPLS or Multi-Protocol Label Switching can transport almost any protocol, it can be set up to mimic the Internet while keeping your data private. Only the locations that you set up can exchange traffic. No one outside of your user group can capture or view your data. You’ll have any to any connectivity within the group with security sufficient to address HIPPA or similar government regulations.

In fact, TelePacific set up just such a private IP Network for a medical imaging organization with 6 locations. They use it to transport patients’ private medical records among their location. Referring physicians can access patient imaging results within hours at their own computers. The system is also used for claims processing, patient scheduling and registration. Interestingly, this system also allows dedicated Internet access through a single firewall at corporate headquarters.

The TelePacific 1Net IP VPN has both cost and performance advantages over other secure networking solutions, including private line, ATM and Frame Relay. You can specify up to six different Classes of Service (CoS) to support sensitive real-time services such as VoIP telephone and teleconferencing. On Net, latency for all CoS is specified at 50 msec. That rises to just 100 msec for extended reach locations off the TelePacific network but still within the US. Network availability is 99.999% (5 nines) both on and off network locations.

The Classes of Service are CoS 1 for VoIP real time traffic, CoS2 for video conferencing and real time data traffic, CoS3 for high priority, delay sensitive business data like Ecommerce and Citrix, CoS4 for medium priority delay-sensisitive business data such as CRM and WebEx, CoS5 for general less delay sensitive business data like ERP, and CoS6 for best effort traffic with no prioritization. That’s typically Email and FTP.

Are you cringing at the cost and effort involved in linking your business locations by private lines or frustrated by the highly variable performance and difficulty in securing the Internet? Perhaps the best solution for your business needs is a private IP VPN based on MPLS networking. Check prices and features to compare with your other choices.

Metro Ethernet vs MPLS Networking

In addition to dedicated Internet access, many companies also need point to point private lines and/or multipoint network connections. The classic way to accomplish this has been to lease private lines to create your own wide area network setup. There are two other methods available that can give you the same results for considerably less cost.

Metro Ethernet service has been seen as a way to get point to point connections in town at a lower cost than leasing dedicated line services, such as DS3 or OC3. This service is called E-Line or Ethernet Line. It’s is standardized by the MEF (Metro Ethernet Forum) so you can compare E-Line services from multiple vendors and know that you are getting the same product.

What’s the difference between ordering an E-Line connection at 50 Mbps versus a DS3 dedicated line at 45 Mbps? When you order a dedicated line, you can envision having a pair of wires going from your headquarters, through a cross-connect at the telco central office and then out to your branch office. That’s probably true for a T1 line provisioned on two twisted copper pair. When you get into DS3 and higher bandwidths, your connection will probably be carried via SONET fiber optic service using an add/drop multiplexer. Along the way, your signal will be traveling with many other who share the same fiber strand.

Here’s what’s important: Unless you actually go out and construct or lease the copper or fiber transmission medium, you are using a shared or multi-tenant service. It’s true with Metro Ethernet and MPLS Networks. It’s also true with dedicated line services. The difference is that MPLS and Metro Ethernet are packet switched networks while T-Carrier and SONET services are circuit switched. With circuit switching, the circuit is used only for your traffic on a single path that is “nailed up” for the time you hold the lease. With packet switching, other traffic can share common paths through the network. That does two things. It lowers the price of the service and it makes some additional services possible.

Metro Ethernet has both an Ethernet Private Line and Ethernet Virtual Private Line service available. The virtualization means that you only need to install one Carrier Ethernet port to have connections with two or more locations. The actual physical line is shared among your own traffic. You may have ten or more branch offices, retail stores or other locations in town. With EVPL you can have point to point connections to many locations coming in through one UNI (User Network Interface).

Here’s another service you can get with Metro Ethernet. It’s called E-LAN or Ethernet LAN service. This is a meshed network that lets many locations all communicate without going through a single point. E-LAN is popular for interconnecting a company’s many independent LANs in the same geographical area. This can be done at the layer 2 level so that the entire network looks like one giant bridged network.

Interconnecting multiple locations is also the domain of MPLS or Multi-Protocol Label Switching networks. Many of these have regional, national or even international service footprints so that all of your far flung locations can interact on the same network. MPLS may be the solution of choice for covering geographical areas larger than a single city and its suburbs. MPLS can also be used to create point to point connections for only two locations. When those locations are located on opposite coasts or in different countries, MPLS can be a better deal than Ethernet Line service or point to point dedicated line services.

Since Ethernet and MPLS services overlap to some extent, what criteria do you use to make a choice? I’d recommend getting price quotes for these, plus dedicated lines, and comparing the total lease cost for the same bandwidth and other requirements. You can get networking bandwidth quotes from multiple service providers quickly and easily using the GeoQuote tool. In fact, many line services to 1 Gbps quote automatically online.

EarthLink Means Business With 10 GigE Fiber

Most of us remember EarthLink from land rush days of the Internet when anyone and everyone just had to get on the net now, and dial-up 56K service was the best you could get. EarthLink is still a viable ISP for consumers with both dial-up and broadband access available. But there’s another side to this famous company. EarthLink Business is a facilities-based competitive carrier serving everything from SMB to enterprise needs with over 28,000 miles of fiber installed and more in the works. They’re in the process of installing two new 10 Gigabit Ethernet fiber rings in Ohio and Eastern Pennsylvania. There’s also a new high speed fiber route going in between Philadelphia and Pittsburgh.

What’s with all the new high-bandwidth construction by EarthLink and others? In case you haven’t heard, business is automating like crazy and heading to the cloud. The enduring slowdown in economic expansion has given corporations a chance to re-examine their operations and re-engineer for what they’ll need in the future. One thing they’ve found is that office automation can be as big an enabler of employee productivity as the factory automation of decades past. That means more computers, more processing and more communication between business sites, vendors, customers and remote employees. Any business that has outsourced overseas has found that a key to making this work efficiently is to tie together the far flung operations as if they were right next door. You can’t do that physically, of course, but you can do it virtually if you have the right networking.

The cloud is also seen as a game changer in a world where it’s hard to predict what resources you’ll need next season or even next month. Traditional in-house data center construction is a capital and time intensive approach. If what you are doing will run just as well in a remote data center, you gain the advantages of avoiding capital investments and buying what you need by the moment with the knowledge that additional resources are always available when you need to scale up. Scaling up is the expected path as a company grows over the years. Now you have the option to scale up and scale down as business fluctuates so you never have idle resources running up expenses.

The one thing that process automation, outsourcing and cloud operations have in common is that they are bandwidth intensive. That bandwidth was fairly easy to come by when everything was on your local network. Now you need the same big conduit going between cities, across the country and perhaps overseas.

SONET is the proven core network technology for fiber optic WAN networks. You can certainly run legacy OC3, OC12 and OC 48 fiber optic connections for your business connectivity. But today it’s Ethernet services that are hot. No problem. Ethernet runs over SONET just fine. In fact, many advertised Ethernet fiber optic networks are really running SONET at their core. OC-192 is a good match for 10 Gigabit Ethernet, with a special WAN-PHY protocol designed especially to transport 10 GigE on a OC-192 optical carrier.

EarthLink is expanding their nationwide fiber network and their suite of business telecom services that include MPLS networking, full and fractional DS3, EVDO 3G wireless, SIP trunking and Metro Fiber Ethernet. They added three new data centers in Rochester, NY, Marlborough, MA and Columbia, SC with 10 Gigabit fiber rings connecting each location to the network backbone. Such high bandwidth connections allows them to offer real time data replication and cloud services to interested companies.

Is your business re-engineering for higher productivity and more agile operations? If so, you may benefit from some of the new cloud services and high bandwidth network connections that have become recently available. Even your current operations can cut costs while retaining the same performance with competitive telecom services.

Types of VPN Connections

Virtual private networking is heavily used in business. In fact, you probably have used a VPN connection today without even realizing it. It’s not a belt and suspenders service anymore. VPN connections are absolutely essential to prevent being robbed blind.

First, let’s take a look at private vs virtually private networks. Your hardwired LAN is a private network. It would take some real effort and a lot of risk for someone to tap into your network wiring and install a device to capture traffic. The same is true if you establish a wide area network or WAN using point to point private lines. A PTP T1 line falls into that category. While it is not impossible to sneak into your wiring closet or even the telephone company and put a tap on the line, it is so difficult that only those with the most secure requirements will go to extremes to protect against this type of attack.

What distinguishes a private network is that 100% of the traffic is yours and yours alone. You are not sharing the lines with anyone else. The advantage to a private network is inherent security. The disadvantage is cost. You pay for all the construction, maintenance and monthly lease fees. It’s unlikely that your private network will be fully loaded at all times. Whatever capacity is unused goes to waste.

Contrast the private network with a public network like the Internet. They are polar opposites. The Internet allows anyone and everyone access by design. Traffic on the Internet is everybody in the pool. Your packets are intermingled with everyone else’s. Even so, a wired connection to the Internet isn’t the worst situation. That belongs to the unsecured wireless network. No need to plant malware in someone’s computer when everything they are doing is perfectly visible on any WiFi enabled computer within range. You are most vulnerable reading private unencrypted emails in a popular public hotspot. Anyone with a laptop computer and some easy to obtain spyware can be reading your messages right along with you.

It seems like such a crying shame that the one network that any employee can access at home or while traveling is such a security nightmare. That’s where the technique of encryption becomes valuable. It doesn’t matter if someone is monitoring your traffic if all they see is gibberish. You encrypt your message at one end and decrypt it at the other end and you have a created what is known as a secure tunnel through the Internet. The public network has now become a virtually private network. It’s not a private network because you are still sharing the transport with many others. It’s virtually private because no one can read your traffic and make any sense out of it.

There are two popular methods of creating Internet or IP VPNs. One is IPsec or Internet Protocol security. The other is SSL or Secure Socket Layers. IPsec is based on software installed in both the company server and the client computer. IPsec encrypts and decrypts each packet, so once you have it installed you have a virtually private line to the company no matter where you hooked to the Internet. Of course, you need to use the specific laptop or other computer set up to work with this system. You can’t just go to any computer and connect back to headquarters.

If you want to do that, you need SSL (Secure Socket Layer). The beauty of SSL is that the software is already built into Web browsers and some email programs. SSL has been popularized for ecommerce and online banking. When you go to a SSL enabled webpage, you’ll notice that the http:// has become https:// The “s” means secure page. To access it you need a user account ID and a password at a minimum. Some sites go further and ask personal challenge questions or display special graphics that give you confidence you are logged into the correct site.

For corporate wide area networks, an alternative to private lines is the MPLS network. These are multi-tenant networks that spread the cost of building and running the system among many users. MPLS networks are considered VPNs because they use a proprietary label switching protocol that isn’t compatible with IP tools. This unique protocol plus access controlled to a limited number of business clients and not the general public give MPLS networks an enhanced level of security.

Do you need private or virtually private network connects to conduct business? If so, compare VPN options and prices to help decide which mix of network techniques is right for your company.

Fiber Lit Towers Improving Rural Broadband

Anyone situated beyond the city limits knows the frustration of living in a bandwidth-free zone. Consumers and small businesses may be near enough to a cell tower to get 3G wireless and certainly two-way satellite is an option, but with severe download restrictions on both. Business sites and farmsteads can probably get T1 lines at 1.5 Mbps and maybe bonded T1 lines to improve a bit on that. How about high bandwidth wireless? Forget it. Fiber optic Ethernet connections? Are you nuts?

Rural America is truly at a disadvantage compared to the telecommunications resources found in cities and suburbs. The best options are found in the core of large metropolitan business districts. Move downtown in a big city and you’ll find such niceties as Gigabit Ethernet and even 10 Gig E connections. You may even be able to get Ethernet over Copper at 100 to 400 Mbps. Fixed wireless services easily deliver 50 to 100 Mbps bandwidth. If a shared bandwidth solution is OK for what you are doing, it’s hard to beat the Cable MSO prices.

Why the big discrepancy between metropolitan and rural service options? It’s all about infrastructure - the infrastructure that was never installed. Well, that’s in the process of changing right now. Level 3 Communications, one of the premier international telecom carriers, has established a program called EON or Extended On-Net sites. What they are doing is building out 500 additional access points to their fiber optic network. They are mostly in small and rural markets where there are few service options available. This is a wholesale, rather than retail, service intended to give local service providers access to high bandwidth carrier services.

Even with fiber optic gateways in the boonies, you still need a way to get the signals to the businesses and consumers without having to spend a fortune creating the remainder of the needed infrastructure. One technology that makes excellent sense for thinly populated areas is fixed wireless. WiMAX is an example of wide area coverage with significant service speeds. What you need, then, is access to the carrier-class fiber bandwidth plus a tower to transmit that bandwidth wirelessly to users scattered far and wide.

This sounds like a perfect opportunity for a combined effort and such a deal has been made. 52Eighty, a provider of tower infrastructure, has entered into an agreement with Level 3 to create 200 new wireless tower access sites situated near Level 3’s EON gateways. 52Eighty will take care of tower construction. Level 3 will provide transport and services that include private line, Ethernet and wavelength services. EON also offers backhauls that include Internet, VPN and voice services.

If this sounds a lot like what has been called the rural broadband initiative, it’s because that’s exactly what is going on. Level 3 is a key “middle mile” provider in bringing high speed network access to rural areas where local service providers can connect. They were awarded $13.7 million this summer through the American Recovery and Reinvestment Act and matched it with $4.2 million of their own funds to create dozens of middle mile connections in rural California, Florida, Georgia, Kansas, Tennessee and Texas.

Does this mean that relief is coming to disconnected consumers and businesses in Rural America? It’s certainly on the way. In fact, many carriers are expanding their wireline, broadband and fiber bandwidth services to garner new customers. If your ISP or business has been unable to get connectivity in the past, now is a good time to check availability and prices online for fiber optic lines to 1 Gbps, plus T1, ISDN PRI and other bandwidth services. You may be surprised by what has become available recently.

Who Still Needs a T1?

With all the hoopla over copper and fiber Ethernet, plus new options in Cable broadband, that stalwart of business connectivity, the T1 line, is getting little fanfare these days. Does that mean that T1 is on its last legs? Or, is there a future for this proven telecom service?

Far from fading out, T1 is as popular as ever. New installations are being provisioned as you read this. The fact that T1 has been around for decades is one of its strongest features. That and the decline of T1 prices in tandem with competing Ethernet over Copper services are keeping T1 in the game.

So, who really needs T1? You do if you need professional grade dedicated bandwidth, secure point to point connections, or robust telephone trunking. That’s especially true if your business location is a bit off the beaten track. If you can’t get any wireline service other than plain old telephone, you probably can get a T1 line installed.

T1 has almost universal connectivity today. To understand how that can be when DSL and Cable rarely go past the city limits and Ethernet services are mostly found in business districts, we have to look back at why T1 was developed in the first place. We think of T1 lines as wide area network connections today, but in the beginning T1 was a telephone trunking system.

Prior to WWII, telephone companies connected to each other through analog lines on telephone poles or underground cables. Carrier telephony used a frequency division multiplexing scheme to load multiple conversations onto a single pair. In the 1950’s, Bell Labs developed digital multiplexing to replace the analog systems. The basic digital trunk was defined in the T-Carrier specifications. T-Carrier includes T1 and T3 lines.

The genius behind the design of T1 is that it runs on two pair of ordinary twisted pair copper. This is the subscriber loop connection that is installed in every business for telephone service. The wires are the same, but the signals on a T1 line are digital, not analog. While one copper pair can carry one business phone line, two copper pair can carry 24 phone lines or a digital bandwidth connection of 1.5 Mbps.

Another smart thing about the design of T1 is that provisions were made to boost the signal so that it can connect far flung locations. Not every business location is within a few thousand feet of a telco central office. Even analog signals fade out with distance. The much higher digital signal frequencies fade out much quicker. That’s why DSL is hard to come by. Unless you are close to the phone company CO, the DSL signal has little bandwidth capability left by the time it gets to your place.

The T1 support system was designed with a device called a regenerative repeater that can be installed in the line every mile or so to complete regenerate the signal. The noisy and faded input signal is boosted and reshaped so that at the output it looks like what comes out of the central office. Keep adding these repeaters and you can extend T1 service far out into the countryside.

If you have a business on the edge of town or in a remote location, you may still be able to get a T1 line for a reasonable price. The only real competition is two way satellite broadband. It works, but has very long latency times that make telephone service perform poorly, is subject to rain and snow outages, and has download limitations. If you exceed your quota, your speed will be reduced so that you don’t hog the limited resources of the satellite.

T1 has none of those problems. You get a rock solid 1.5 Mbps in both the upload and download direction. Load it full up with data transfers 24/7 or use what you need, the price is the same. Latency is negligible for most applications. In fact, T1 works great as a multi-telephone service or in the ISDN PRI configuration that supports most PBX telephone systems. You don’t have to get an Internet only data connections. T1 lines can be ordered between two business locations for a private line connection.

If you’ve been involved in pricing telecommunication circuits over the years, you may cringe at the thought of going out and getting a new set of competitive quotes. You have to locate carriers that service your area, make calls that often go to voice mail and then degenerate into phone tag, get written quotes and sort through all the fine print to make sure you are comparing apples to apples. Even after all this time, effort and eye strain, how can you be sure you didn’t miss the really good deals?

Using legacy methods, your results really are likely to be hit and miss. That’s why Telarus, Inc. invested years and millions of dollars refining a modern automated process that locates providers that service your location, interacts with their pricing systems, and generates online quotes displayed as a table of options priced from least to most expensive. It’s almost like having a dedicated staff member to do the research and compile a report, only a lot faster.

Fiber Network Quotes uses the Telarus GeoQuote real time pricing service to generate both copper and fiber line service prices from 10 Mbps up to 1 Gbps any time you care to use it. Too harried during the work day? No problem. You can run these quotes on a laptop from your favorite coffee shop after five. The system is even available nights and weekends if that’s when you have a few quiet moments to spare. Generate a single T1 line or Gigabit Ethernet quote or investigate a few other possibilities. It tells you which quotes can be provided immediately and which require some manual processing and will be emailed in a few hours or a few days. The tricky ones are multi-location MPLS networks and the like.

You’re not left to the machines completely. An expert Telarus bandwidth consultant is available at no cost to help you assess your needs and compare offers from competing carriers. Just indicate that you’d like a phone call and you’ll get a response promptly.

Are you in the market for additional telephone trunk line capacity, higher WAN bandwidth, networks to transparently link your many business locations? Perhaps you just have an unsettled feeling that you are paying more than you’d have to, considering the rapid increase in competition among telecom service providers. For any of these reasons, just find a few minutes in your busy schedule and get real time telecom line and network prices now.

Cloud Computing For Disaster Recovery

It’s been quite a year for natural disasters. Fires scorching thousands of acres at a time, rivers overflowing their banks, torrential rainfall, tornadoes everywhere. Are you feeling a little nervous that your business could be taken out at any time?

Sadly, an unfortunate twist of fate can hit anyone at any time. You probably already have some protections in place, such as property insurance, tape or disk file backups and maybe even offsite storage of important files. Ask yourself this, however. How will you get your business back running immediately after a catastrophic local disaster?

While having copies of critical documents and customer files may prevent you from going out of business permanently if disaster strikes, they aren’t enough to keep you running without a hiccup. For that you need backup infrastructure as well as files. A generation ago, that meant duplicate data centers that were located far apart. The idea is that the kind of disaster that wipes out your facilities is unlikely to hit two geographically separated areas simultaneously. If you are prone to earthquakes, one data center can be local but the other must be in an earthquake free zone. The same thing applies to hurricanes. If you are on the coast, your backup must be far inland.

Today’s disaster recovery solution of choice is the cloud. With infrastructure, platform and software as a service, you can do anything in the cloud that you would do in-house. The advantage is that the cloud is often far, far away.

Why choose a cloud solution over doing it all yourself? Avoidance of enormous capital investment is a very good reason. It’s not hard to spend millions creating the environmentally controlled and secure facilities with robust backup power and multiple diverse bandwidth connections, not to mention the racks and racks of equipment inside. This is one reason why many businesses decide that regular system backups are good enough. If the worst happens, they’ll simply get an insurance settlement and order replacement equipment. Oh? How long will that take? Just what is your income stream going to look line in the ensuing days, weeks or months?

One advantage of the cloud is that it scales fast. You could decide to have a minimal cloud solution implemented right now for the monthly fee it takes for storage and limited server capacity. If you get knocked out where are, you can log-into the cloud from wherever you can get a broadband connection and scale up in minutes or hours. When the crises is over, you can back off from all the virtual servers and go into a standby mode.

By the way, that cloud storage makes an excellent backup for your local files. Cloud storage is robust and almost infinitely scalable. This alone can be the justification for having a backup operation in the cloud.

What if you are in the cloud already? It’s not unknown for cloud systems to suffer outages just like anything else technical. In this case you may want to have a minimal backup system locally, in a colocation facility or set up as a private cloud in a different data center.

Hosted PBX phone systems can also keep you running after a disaster, almost like nothing ever happened. At least that’s the way your customers will perceive. it. You only need a network bandwidth connection and a few SIP phones to get your calls and voicemail. Being a network voice system, those SIP phones can be located just about anywhere... even somewhere else in the country.

Are you apprehensive that your business may not be protected from shutdown as much as you’d like? It may not be that expensive to have backup computing and telephone service in the cloud. Check options and prices now and rest easier that you have a recovery solution.

Is HPBX Your Next PBX?

It’s almost back to the future, to coin a phrase. Companies nationwide are getting rid of their phone switching equipment and going back to service providers, what we used to call telephone companies. Only the phones and the telephone trunk lines remain. Is technology reversing itself or is there something new going on here?

Make no mistake about it, telephony today is different from the telephone service of yesteryear. But there are similarities, too. What companies have found is that building and maintaining little telephone companies in-house entails a lot more cost and bother than you might expect. If that’s true, though, why did they ever leave good old Ma Bell in the first place?

One problem with business phone service versus what you have in your home is that there are lots and lots of phones. If you only have one or two lines, you probably have just one or two phones. It’s likely that each phone is tied to a particular phone line. Perhaps you have multi-line phones where each line has a switch or “key” so you can select it. Some small offices have only a single phone set one one line and use a second line to connect a FAX machine or credit card terminal.

So what’s the problem with having so many phones? It’s pretty likely that by the time you have a few dozen phones, your office facilities are so spread out that people can’t lean over to the next desk and have a conversation. They either have to get up and walk down the hall or make a phone call. If each phone has its own line, then those calls will go through the phone company and you’ll likely pay a charge. If you want to talk to someone in a branch office in another state, you’re surely going to pay long distance charges.

What companies really wanted was something of an intercom feature, where they could just dial a few digits and get to another phone in-house. To accomplish that, they bought PBX or Private Branch eXchange equipment. The PBX is the device that connects phones and also managed outside lines as needed. All the phones connect to the PBX and the PBX connects to the phone company, but only for calls leaving the premises.

The local telephone companies offer a service called Centrex (Central Office Exchange) to compete with the PBX. The switching equipment is kept at the central office, like always, but the system functioned more like a PBX. The Centrex system based on the individual copper pair from each phone to the CO is now being replaced by HPBX or Hosted PBX service.

What’s different about HPBX is that it is a VoIP phone system. Communication is over a WAN network connection called a SIP Trunk. This frees the user from being tied to a particular local phone company by those ubiquitous twisted copper pair. Now any service provider anywhere in the world can be your phone company as long as you can get a digital connection between their facilities and yours. What you need in-house is IP phones, also called SIP telephones, connected to your converged voice and data network. Your service provider hosts the PBX switching function with termination to the public switched telephone network as needed.

Are you ready for a phone system upgrade or merely concerned that what you are doing now costs more than it could? Get competitive quotes for hosted PBX telephone systems, some of which include new phones as part of the service fee.

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.

Ethernet over Copper Connects Nationwide

Ethernet over Copper (EoC) has quickly made a name for itself as a last mile access connection for dedicated Internet, MPLS networking, and linking two or more company LANs. The flexibility, ease of interface, and cost savings make this a service in demand. What’s held it back to date is lack of availability. Well, that’s about to change.

MegaPath, one of the country’s major competitive carriers, is moving in with Telx, a major network interconnection provider. What does that mean? It means that your Ethernet over Copper connection can go a lot farther than it used to.

MegaPath has been on a major construction effort to roll out EoC equipment to over 680 central offices within the next year. The central office is key because this is where the subscriber copper loops terminate. MegaPath used specialized G.HSDL technology with up to 8 bonded copper pair to deliver line speeds to 100 and even 400 Mbps in selected area. Their standard symmetrical speeds are 2, 3, 5, 8, 10, 12, 15, and 20 Mbps. Both layer 2 and layer 3 services are offered along with QoS/CoS to support business data and real-time voice and video simultaneously.

For its part, Telx operates 15 data centers with direct access to over 950 customers who have chosen to colocate within the Telx facilities. These include major telecom carriers, Internet service providers, content producers and delivery networks and cloud service providers. Telx is a pioneer in Ethernet Exchange, a way for carriers to exchange Ethernet traffic without having to first convert to another protocol like SONET. The E-NNI or Ethernet Network to Network Interface benefits each carrier who participates because now they can directly access customers on other carriers and vice-versa.

Ethernet over Copper along with Ethernet over Fiber form the basis of Carrier Ethernet. This is the familiar Ethernet protocol that runs on your LAN adapted for use on telecommunication networks. The Metro Ethernet Forum (MEF) has standardized a number of Carrier Ethernet standards so that they are compatible across network boundaries. These include EPL, EVPL, and ELAN.

EPL stands for Ethernet Private Line. This is equivalent to the point to point private line services familiar with T-Carrier and SONET services. EVPL is Ethernet Virtual Private Line. This is very similar to EPL. The virtual designation means that you can have a number of EPL services running to a single physical Ethernet port. This is particularly useful for companies that want to run private lines from a single headquarters location out to multiple branch locations. Together, EPL and EVPL form what is known as E-Line or Ethernet Line service.

ELAN stands for Ethernet LAN Service. You may also see this written as E-LAN. What differentiates E-LAN from E-Line is that E-LAN is a many to many or mesh network service. You can use it to tie together multiple business locations so that any location can communicate with any other.

Have you been interested in Ethernet over Copper services but concerned that they may not be available to support your particular location or your many locations nationwide? This is a rapidly changing market, with more service being rolled out almost daily. If you haven’t checked lately, you may be pleasantly surprised at how much connectivity is available and how much bandwidth your can get for your telecom budget. Check pricing right now, if you like. Ethernet over Copper prices from 1 to 100 Mbps are available instantly online. Other services for business locations will be promptly quoted by a Telarus bandwidth expert, upon request.

Ethernet Service Providers Offer Cost Savings

One technological revolution quietly underway is the transition from circuit switched to packet switch WAN protocols. Many businesses first become aware that something is happening when they go to get price quotes for bandwidth upgrades or new line services. They expect to be buying a T1 line and find themselves ordering Ethernet over Copper instead. Why is this and what can you get for your bandwidth dollar these days?

The shifting ground of the telecom industry is being driven by a move to all-IP networks. The root cause is that computing devices, such as PCs, web servers, wireless access points, tablets, smartphones, telepresence, and IP PBX systems are generating network traffic that far exceeds traditional telephony. I included IP PBX in that group because an enterprise VoIP system with SIP phones connects via the LAN and uses Ethernet packets, not analog or proprietary digital signals. In most businesses, the common denominators are the LAN and the telephone network, with the phone network on the way out.

We’re now at a point where the crying need is to connect LANs together and to the Internet. We’ve been doing that with traditional telephone technologies such as T-Carrier and SONET for decades. If you were designing a comprehensive networking approach, would you pick one technology for the LAN and something completely different for metro and long haul networks? Wouldn’t you try to have a common protocol that runs everywhere for efficiency and ease of connection?

That’s what’s behind the rise of Carrier Ethernet. As more competitive carriers enter the market and older networks are upgraded, IP core networks are becoming more and more the rule. These are high speed fiber optic networks that have regional, national or even international service footprints. The last link in the chain is appropriately called the last mile connection. This is the wireline, fiber or wireless link that connects you to the service provider point of presence.

Ethernet services are available at every level of networking, from simple Internet access through international MPLS networks that link hundreds or thousands of sites. Most companies will want some type of dedicated Internet access. A 2x2 Mbps or 3x3 Mbps Ethernet over Copper line is a direct competitor to T1, at about the same price. It’s not uncommon to get twice the bandwidth for the same cost by choosing Ethernet rather than T-Carrier T1 or T3.

Ethernet is also more scalable than other telecom services. Typical bandwidth options include 2, 3, 5, 10, 15, 20, 30, 50, 75 and 100 Mbps. Other increments between these levels may also be available, depending on the carrier. Those are just Ethernet over Copper offerings. Ethernet over Fiber takes you to 250, 500, 750 and 1,000 Mbps or up to 10 GigE.

You may want to install Ethernet Private Line or Ethernet Virtual Private Line service for a point to point connection between two business connections, like headquarters and a branch office. This replaces T1 or DS3 private line service at a better price.

One service that Ethernet offers, that you won’t find with traditional point to point connections is E-LAN or Ethernet LAN Service. It connects multiple LANs in a mesh topology at the layer 2 level. This lets you build one giant LAN that includes all of your remote location LANs.

Would you like to expand your service options and save 50% or more on line pricing compared to what you have now? Get instant online Ethernet service pricing up to 1 Gbps now. More complex multi-site networks need a bit of manual work, but will be quoted promptly.
