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

A business t1 line is a high speed 1.54 megabits per second (mbps) circuit which is comprised of 24 individual DS-O circuits. Each DS-O circuit has a speed of 64 kilobits per second (kbps). For perspective, your home telephone line is the equivalent of a DS-O circuit. Business T1 lines are also at times referred to as DS1 lines. (For more about business T1 please click here)

Business T1 Definition Continued.

A business T1 circuit is carried through two twisted pairs of copper wires. Virtually, all residences and businesses currently have two pairs of copper wires running to them. T1 lines are capable of delivering 1.54 Mbps simultaneously in both directions (both upload and download), one direction for each pair of copper lines. Because T1 circuits are repeater driven (signal is digitally reestablished every 6000 feet), it is available virtually everywhere. The price however is affected by distance from the provider’s point of presence (POP), and number of times the signal must be reestablished. When the signal is reestablished, it is perfectly duplicated at near the speed of light, so signal quality is not lessoned by distance. However, because there is cost each time the signal must be reestablished and for the facilities used for the distance from PoP the signal must be carried, business T1 circuit price quotes are generally significantly higher for locations which are remotely located. T1 lines are dedicated, in that they are not shared like DSL or cable, always connected, and are extremely stable. Most reputable providers include service level agreements (SLAs), which guarantee the reliability of their T1 circuits, with built in penalties for the provider if written reliability and circuit quality commitments are not honored. SLAs however can provide a false sense of security. Some of the tier 1 providers with the highest reliability and quality standards do not offer SLAs. In most cases, the penalties to the provider, included in SLAs for when circuits are down, or not working properly, do not come close to compensating for lost revenues which can result from circuit down time. For this reason, it’s more important to look at a company’s established record of circuit quality and reliability, than to go with a less reliable tier 2 provider, simply because they provide an SLA. Business T1 circuits can transfer data in many forms to accomplish a variety of functions. These include: fractional T1 (commonly 128 Kbps to 1024 kbps), burstable, integrated (one T1 line comprised of any combination the types of T1 listed here), channelized DS1 (a type of integrated T1, the other is dynamic integrated), point-to-point (direct private circuit between to locations), dynamic integrated, local (local phone service), PRI (voice service which includes many added features which cannot be provided by regular voice T1), and frame relay. Each of these types of DS1/T1 has advantages over the others, depending on the specific needs of your company. Also, the availability of each is based on the offerings of each T1 provider and the geographic proximity of the provider to your business.

Is PRI the Right Choice for Your Company?

Written by: Dennis Green - Jul 5, 2008

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 T1 lines are commonly configured so that 23 channels serve as B (Bearer) channels and one as a D (delta) channel. Each B channel serves as a voice (telephone) channel. The D channel provides 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 internet, 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 T1 and traditional integrated T1 is that T1s which are not PRI require 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 non-PRI T1. With T1 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 T1 lines. This frees the 24th channel of each of the other PRI lines so that they can be used as additional bearer channels. Because PRI lines serve as a direct connection to the telephone company’s central office, PRI is often the preferred choice of PBX customers. PRI T1 provides many advantages over traditional voice T1. These include: call by call service selection, more PBX users can be supported, caller ID, DID (direct inward dial) numbers, messaging, and video conferencing. Because of increased efficiency provided by PRI, companies which switch to PRI from traditional voice 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. PRI T1 is available in most major metropolitan areas, but is not available in most isolated rural areas.
