ISDN PRI is sometimes known as T1 PRI. ISDN stands for Integrated Services Digital Network. Pri splits a T1 digital signal into 24 channels of 64 Kbps per channel. You can assign 23 of these channels as one telephone call each, the equivalent of having 23 separate telephone lines. The 24th channel is used for signaling information. T1 lines (link) are digital telephone line which can transfer data at 1.544 megabits per second. T1 lines are a type of ISDN communication.

Hope this helps!
