I’ve read about 15 different blogs & websites, and no one seems to agree on a clear cut definition of the difference between what a T1 & PRI is!
My understanding (and what I believe is correct) is that the T1 is the actual HARDWARE that provides the interface for connectivity to the ISDN. The SERVICE that runs over the T1 is called either a PRI or BRI. The BRI has basically 3 dedicated lines, whereas the PRI has up to 24 channels.
Am I missing something? Is there another way or service that allows the T1 to communicate with the telco provider?
I’ve read so many different websites that have referred to the T1 as the actual SERVICE and the PRI as an entirely different SERVICE that all it has managed to do is thoroughly confuse me!
