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.

High Bandwidth Dissimilar Line Bonding From Mushroom Networks

How would you like to build your own fiber optic bandwidth broadband service without paying through the nose for SONET OC3 or higher level service? Can you do it by kludging together whatever you can find in the way of DSL, Cable broadband, T1 lines, DS3 bandwidth, or wireless Internet service? Not very well, and you know it. But what if there was an appliance available where you simply plug-in five or six of your favorite high speed connections of any type and it smoothly merges them into one screaming high bandwidth service?

"Impossible," you say. "We tried that with our routers and it didn't work at all."

Well, what you need is not another router. You need the new and improved Truffles from Mushroom Networks.

Last year, we thought the Truffle BBNA6401 was just the nuts (or fungi) for both WAN reliability and bandwidth expansion up to 50 Mbps. The "BBNA" stands for Broadband Bonding Networking Appliance. It could also mean Broad Band Network Aggregation, which is how the device works. It bonds broadband services to aggregate or combine their bandwidth into the equivalent of one faster line.

T1 line bonding is commonly available from competitive carriers. For every line to bond-in, you get an additional 1.5 Mbps of bandwidth. There are a couple of restrictions. It's usually only practical up to 10 or 12 Mbps and all the lines have to be identical and from a single supplier. The carrier supplies you with premises equipment that is similar to the equipment at their central office. That's what runs all those T1 lines in parallel so that you experience the equivalent of a single higher bandwidth line service.

The Truffle looks at that approach as keeping companies in the dark and feeding them fertilizer. Instead, they manage the bandwidth of the lines rather than the lines themselves. By keeping track of what requests go out which lines and what responses are received, the Truffle can mix and match any broadband service into a common bandwidth pool. It doesn't really matter what the characteristics of individual lines are. A DSL and T1 line can be paired, then aggregated with a cable modem signal, a satellite receiver and a wireless cellular aircard. Your composite bandwidth is the sum of the speed that each line transmits and receives.

You can see the advantage of this approach for growing bandwidth incrementally. You start with whatever you can get. Then add services as they become available or you can afford them. In addition to speeding up your WAN connection, you also get a boost in reliability. That DSL line may be moderately fast but flaky. The cable modem is cheap and screams with speed, but drops the connection a couple of times a day and some days goes down for hours. T1 lines are rock solid but the cost per Mbps is way more than with the shared "consumer" grade services. DS3 is fast and reliable but lease prices are in the 4 digits per month. Since it is unlikely that you'll lose every service at the same time, broadband bonding can give you solid connectivity all the time with high bandwidth most of the time.

In addition to the latest speed upgrade, Mushroom Networks now offers several flavors of Truffles for various size businesses and applications. The Porcini BBNA is intended for SMB and enterprise clients, apartments, hotels, hospitals and multi-tenant buildings that want to aggregate several types of Internet connection into one high reliability broadband service. The PortaBella BBNA is for portable or mobile applications. It aggregates the bandwidth of up to 5 USB wireless modem aircards. There's even an optional service offered that makes this solution suitable for high quality video streaming.
