Integrated T1 PRI

“When the top T1 providers must compete for your business, you win!”

PRI (Primary Rate Interface) is an ISDN connection designed to be provided over T1 lines. In the United States, a PRI line consists of 24 (64 kbps each) DS0 channels. PRI lines are commonly configured so that 23 channels serve as B (Bearer) channels and one as a D (delta) channel. Each B channel carries data, voice, and other services.

Integrated T1 PRI Definition Continued.

The D channel carries control and signaling information for the B channels. B channels can be used as independent channels to simultaneously provide a variety of services such as data, voice, or imaging. They also have the flexibility to be bonded, as needed, to provide higher bandwidth for special needs such as video conferencing. A significant difference between PRI and traditional integrated T1 is that integrated T1 requires a portion of each channel to be allocated for signaling functions. This results in a reduction in effectiveness, efficiency, potential and bandwidth for most functions of each channel of traditional T1. With PRI, all signaling functions are provided by the 24th channel. This leaves each of the other 23 channels with a full 64 kbps which can be fully dedicated to bearer functions. One D channel can provide signaling functions for several other PRI lines. It is not uncommon for two D channels (one as primary, one for backup) to provide the signaling functions for a span of as many as 20 PRI lines. This frees the 24th channel of each of the other PRI lines so that they can be used as additional bearer channels. PRI provides many advantages over traditional T1. These include: dynamic channel allocation, call by call service selection, more PBX users can be supported, caller ID, messaging, and video conferencing. Because of increased efficiency provided by PRI, companies which switch to PRI from traditional T1 often find that they not only receive a much greater variety of services but often do not need to pay for as many trunks as they needed prior to the change. Integrated T1 PRI can come in many forms and variations, as mentioned above, but the most common integrated T1 PRI is a combination of PRI and data internet channels on one integrated T1 line. This service is very popular for small to medium companies which need all of the telephone functionality that PRI can offer, plus an extremely stable internet connection, but only have the budget for one T1 circuit.

T1 Consultation Is Important

Written by: Dennis Green - Aug 28, 2008

Deciding which T1 provider will best serve a customer can be a complex process. Consultation during this process can be invaluable. Especially, if this consultation is unbiased, free, and without obligation. T1consult provides free consultation, and because we are the authorized agent for all 20 of the top T1 providers in the country, our advice is without bias. Other, than our goal to ensure that the customer receives the best possible service, for the best possible price, we do not favor any one provider over the others. As we assist customers to determine which provider will best meet their needs, many factors are considered. Four of the most important of these factors include customer need, proximity of the customer to the provider, provider perception of competition from other providers, and services offered by the provider.
