How many digits should the phone company send on a channeized T1 to our Portmaster?

0

Sending digits on a channelized T1 refers to DNIS (Dialed Number Identification Service). It is not supported on the PM3 when the line ports are configured for channelized T1. Therefore, tell the CT1 provider to delete all the digits and do not send any on the line. The PM3 is better suited for a PRI, where you DO have the functionality of DNIS over the ISDN D channel.
