What is a NxT1? (....aka Bonded T1 Bandwidth....)

What Is A NxT1? (otherwise known as a bonded T1 line)

With the NxT1 access option (also called a bonded T1 line), the user can obtain bandwidth above 1.5 Mbps (a single T1 bandwidth circuit) without requiring DS3 access. A bonded T1 or NxT1 connects 2, 3 or 4 dedicated T1 circuits (3 Mbps, 4.5 Mbps or 6 Mbps, respectively).

NxT1 Access is provided through a combination of software and hardware components, giving greater bandwidth by automatically load balancing traffic over multiple T1 bandwidth links. At 1.5 Mbps, T1 lines simply do not have sufficient bandwidth to deal with the new demands being made on networks. Yet fiber-based T3 circuits are overkill for many small and midsized businesses. T3 provides 45-Mbps bandwidth, but it comes at a steep premium: T3 circuits lease for upwards of $3,000 a month, compared to as low as $400 for T1 lines. Moreover, T3 circuits are not easily available to many businesses, while T1 lines are ubiquitous.

The price/bandwidth/availability gap between TI and T3 is sending businesses and service providers alike scrambling for cost-effective ways to fill needs. They are finding that, because until recently there was little demand for bandwidth between T1 and T3, no one has developed a truly effective means to fill the T1-T3 gap. Many business users expected that digital subscriber line technology, cable, wireless, or ATM would solve the gap problem. For a variety of reasons, however, ranging from insufficient bandwidth to asymmetric bandwidth (bandwidth upstream is lower than bandwidth downstream), efficiency, or cost, no one technology offers all the characteristics required by business applications.

Asymmetrical DSL is primarily a residential service and is focused on universal ADSL (UADSL), promises to offer speeds up to 7 Mbps downstream. However, it suffers from a low upstream speed of only 768 kbps today. In addition, ADSL has very limited deployment. DSL in general also suffers from a lack of standards and from bandwidth variation depending on the location, length, and quality of the copper lines.

Now, there is an exciting, new approach to bundling T1 circuits that solves the issues that limited the value of earlier NxT1 solutions, promising to finally fill the T1-T3 gap.

This solution employs the industry standard Multilink Point to Point Protocol and Multilink Frame Relay protocol to bundle multiple T1 and fractional T1 lines, creating a single, symmetrical, virtual multimegabit access path with bandwidth equivalent to that of the aggregated copper lines.

For instance, a multimegabit circuit created by bundling together six T1 lines will behave as a single circuit with approximately six times the throughput of a single T1 line but only one-sixth of the latency. The solution is scalable, enabling businesses to start with network access at 1.5 Mbps and move upward as their bandwidth requirements grow.

What Is The Advantage Of NxT1 Or Bonded T1 Bandwidth?

A principal advantage to purchasing multiple T1 circuits is the attainment of diversity across carrier backbones when used with a bundling protocol such as Border Gate Protocol or Cisco Express Forwarding.
