The VWIC2-2MFT-T1/E1 may well do PRI. However, the question is whether its DS0s can be switched to the PVDM2-DM modem card ... and the answer is no.
The PVDM2-DM data sheet
applicable here, and it enumerates the trunk cards with which it can be used:
? NM-1CE1T1-PRI (1-Port Channelized E1/T1/ISDN-PRI Network Module)
? NM-2CE1T1-PRI (2-Port Channelized E1/T1/ISDN-PRI Network Module)
? HWIC-1CE1T1-PRI (1-Port Channelized E1/T1/ISDN-PRI HWIC)
? HWIC-2CE1T1-PRI (2-Port Channelized E1/T1/ISDN-PRI HWIC)
? VIC2-2BRI-NT/TE (2-port Voice Interface Card-BRI (NT and TE))
