Good point. For a PRI you must also specify the switch type that you will be communicating with at the CO.

[7:30507] Some of the differences: a T1 uses Channel Associated Signaling and a PRI uses Common Channel Signaling. Or in English, in a T1 you have 24 timeslots which carry signaling information along with the data(in-band signaling) and in a PRI you have 23 data-only channels and a signaling only channel(out of band signaling); PRI's are used primarily for voice applications, whereas T1s or fractional T1s can be used for voice or data; A T1 is a leased line connection and a PRI is a subsciber connection for access to the PSTN (generally). -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of McHugh Randy Sent: Sunday, December 30, 2001 10:37 PM To: [EMAIL PROTECTED] Subject: Is an ISDN/PRI and T1 the same? [7:30507] Is an ISDN primary rate interface the same as a T1 and do you have to set the framing, linecoding , clock source and carve out your timeslots on both a T1 and an ISDN PRI?
