PRI T1 (Primary Rate Interface)
No matter what type of T1 line you ask for its bandwidth, physical medium, etc we have disucssed before will be the same. However what type of data or how the T1 is used maybe different.
Primary Rate Interface or PRI T1 as it is more commonly know as, is probably the most flexable T1 line available. Remember a T1 is made up of 24 individual channels called DS0’s. With a PRI type interface 23 of these channels, often referred to as B(Bearer) channels, are available for data or voice and the 24th channel, the D(Data) channel is used for signaling. Anyone familiar with ISDN will recognize the terminology. This Data channel can dynamically set up any of the other 23 Bearer channels to carry any sort of data. So one PRI T1 can carry voice, data and then if say you have to have a video conference then 6 channels can be grouped together to carry the video and voice.
This flexibility can be a great solution for small companies that don’t want to purchase multiple T1’s for different solutions. Just fill out this simple form for a free primary rate T1 quote and see the benefits a PRI T1 can offer your business.
