What is PRI ? What are carriers charging ? A sample quote from the US and Canada

A brief technical explanation: PRI, sometimes also called Megalink, digital, or fiber, is a TDM, ISDN type (circuit-switched) type telco service which is rapidly replacing the older style analog line. A standard PRI service in North America has 23B channels and 1 D channel - if added together you have 24 channels. These 24 channels are comprised of 24 channels of 64 kbit / second, or 1.544 Mbit / second (24 X 64). The PRI is a similar service to the T1 - a T1 is made up of 24B channels, or 1.544 MB as well. The T1 has 24B channels, and the PRI has 23B + 1 D channel. The PRI is used for voice, and the T1 is used for data.

The PRI is a digital service, which means that the sound quality is near perfect. Unlike an analog line, which sometimes has a 6 to 8 dB loss, the PRI service has a 0 dB loss, making the sound quality that much better.

The technology has been around for some time - Digitcom.ca has been installing PRI circuits for our clients since the mid 90's. It is a very mature technology, with obviously, a very high adoption rate in the small, mid, and especially enterpise Telecom markets.

Next question: Is your current PRI contract competitive, and how do American and Canadian rates vary ?
