Hello John, Thank you so much for your response
Most T1/DS1's sold are of the ISDN Primary Rate Interface type. They consist of 23 Bearer Channels at 64kb/s that can be used for EITHER voice or data. The 24th channel is labeled the Delta Signaling Channel also at 64kb/s. Most of the time the Delta's only purpose is to process call functions from the CPE EPBX Voice Bearer channels to the Signaling System Seven world wide network "gateway" at the LEC
Even though not as common, I would like to learn more about SS7 interconnects, and how they are generally performed by the carriers (i.e., point codes, signaling etc..). Basically how ISDN/PRI trunks differ from traditional SS7 trunks.
I hope this is not a stupid question
