Converting external CSU to internal CSU

[thomuff]

I have T1 connection. 17 channels for data. The remaining 7 for voice. I have a Paradyne external CSU at each end. What kind of Cisco internal module could I use to replace these Paradyne CSUs and do have example of the configuration. I am pretty sure I would use a VWIC-2MFT-T1-DI but I can't figure out how I configure the voice to go out the second interface connecting the PBX.

Use the 2nd generation card VWIC2-2MFT-T1/E1 for total flexability. The doc you need to configure this card is in the relevant IOS guide.

Although not as exhaustive, one helpful page for config is:
