I haven't been able to get a solid answer from the vendor on this so I was hoping someone here may be able to answer this. If I am receiving an integrated Voice/Data PRI that terminates at a channel bank where voice and data split. The channel bank then hands off data to a cisco device with x amount of data channels and then voice is handed off to another device. Would the data handoff from the channel bank to a cisco router coming from the dsx port on the channel bank just use a wic-1dsu-t1 card or does it need an isdn/pri card?

the normal setup would be a T1 WIC and not a PRI card.  The data output from an integrated V/D PRI is generally "clear channel" bandwidth.  The voice system might need to be a PRI if setup with a T1 / PRI interface, but if the voice is going to a channel bank, then it is unnecessary to have a PRI from the carrier.  The only time the Cisco device would need a PRI card would be if the D-channel from the carrier PRI was pointed to the Cisco router (one of the assigned channels) and used for some type of voice related services.

Great explanation. That is along the lines of what I was thinking and I know that the voice will be splitting off to a pbx system that another vendor handles, so the D channel should be pointing there then. Thanks again!
