PRI T1 - How It Works
Are you interested in the PRI T1 and how it works as well as how it
benefits businesses throughout the world? Of course you are and you
have come to the right place. As we write this article, we are going to
give you some good, reliable information on PRI T1. First of all, we
are going to begin by telling you what it stands for. It stands for
Primary Rate Interface and it is a telecommunications standard that is
used for carrying a number of different DS0 data and voice
transmissions between the user and a network.
Take note that all
of the voice and data channels are running on ISDN and they operate at
64 kbit's. The PRI T1 is the standard connection in most US offices
looking for a feature rich local T1.
In the United States of
America, it is based on a T1 line, while it is based on a E1 line in
Europe. The E1 consists of twenty four channels while the T1 consists
of twenty four channels.
The PRI is known for having a number of
different channels and it all depends on the country. As an example, in
North America and Japan, there are twenty three B channels and one D
channel on a T1. In Australia and Europe, you have thirty B channels
and one D channel that is on the E1 at 2. 048 Mbps.
PRI T1's are
generally used by businesses of all sizes that have digital PBXs in
order to get digital access to the PSTN (Public Switched Telephone
Network). In order to meet special needs, including video conferences,
the twenty three (or thirty) B channels can be reassigned. The PRI is
basically a switched service that can be delivered over a T1
connection. As you see, it is not as complicated as it may sound at
first.
