I'm trying to understand the capabilities of this card, and am lacking in some knowledge of the telephony aspect.
If the T1 I present to this card has PRI signaling, can the D&I functionality allow me to hand, say, half the channels to an otherwise voice-capable router like "controller T1 n/n/n, pri-group 1-12, etc." and then treat the other half as a standard serial frame-relay connection, e.g. "int Se n/n/n.nnn point-to-point"?
In an alternative application, same card, same T1, same signaling, can I take half the channels out of the second port in the card and hand them to a legacy PBX? And keep the PRI signaling?
in theory, yes you can do both things. But in practice, you will find application with "partial PRI" and "partial data" do not exist. What is more common, is that you have T1 CAS voice for some timeslots, and data for the others.
In other words, when there is PRI, most PBX will assume that the entire T1 is dedicated to this.
OK, say we have a 38x5 router, currently with a VWIC-1MFT-T1 terminating a voice PRI, like this:
controller T1 0/1/0
pri-group timeslots 1-24 service mgcp
and a WIC-1DSU-T1 terminating a full T1 frame-relay circuit for data, like this:
description Connected to Qwest Frame Relay T1
no ip address
encapsulation frame-relay IETF
frame-relay lmi-type cisco
interface Serial0/0/0.100 point-to-point
description Qwest to home office
ip address nnn.nnn.nnn.nnn
ip pim sparse-mode
frame-relay interface-dlci 100 IETF
What I want to do, in essence, is to take half that frame T1 and add it to the voice pool. What I'm hoping I can do is to replace the WIC-1DSU-T1 with a VWIC-2MFT-T1-DI (reconfigure the circuit with the carrier as PRI signaling, if necessary), treat 11 or 12 channels of it as frame-relay data and take the other 11 or 12 and add them as PRI to the voice pool. I think (but am not sure) I can do more or less the same with an external D&I mux/CSU.
In other words, you want a 640 kbps (10 x 64) data circuit, and the rest a voice channel / PRI, on a single T1 line. As I said the router should be able to do that, even with the "non-DI" version fo VWIC2, but you have to ask your provider of FR and PRI if they are able to mux both services on a single T1. Sometime this called "integrated access".
