Our customer has a full PRI (along with 23 DID's) coming into the router. The telco is sending the last four digits to router. Out of the 23 voice channels, four (along with four specific DID's) need to be configured so they drop onto the onboard modem card PVDM2-12DM and then sent out Ethernet interface. The other 19 channels will be used for voice only (CCM Environment).
Does someone have an example config for this? I know how to configure a PRI, but how to seperate four channels so they ultimatly get dropped off to ethernet network.
From the PVDM2-xDM data sheet, it leads one to believe that one can have modem calls and traditional voice calls coming over the same ISDN PRI from telco. I understand your recommendation above, but do not have the available Vwics to make that happen. Can you read verbaige from the data sheet (i pasted below) and tell me if it is possible to do what I need without the Vwic to NM arrangement you described.
"Single Solution for Modem and ISDN Callers
The Cisco 2800 and 3800 Series routers with Cisco Digital Modem PVDM Modules installed can accept incoming ISDN or voice calls and automatically switch them to the appropriate internal circuitry. The PRI switching is based on Q.931 messaging in the ISDN D channel. This out-of-band signaling channel provides a means for the telephone network to label each call according to its type. Specifically, when an incoming call is labeled "voice" by the telephone network, the Cisco router directs it to one of the router's modems. When a call is labeled "ISDN data," it is directed to one of the router's High-Level Data Link Control (HDLC) controllers. This approach provides the benefit of one phone number for both modem and ISDN users. R2 and CT1 interfaces also support this switching ability".
