Chapter 8 Connecting Voice Network Modules
IP Communications High-Density Digital Voice or Fax Network Module
Note
PVDM and PVDM2 modules are not interchangeable. Use PVDM modules with the NM-HDV network
module only, and use PVDM2 modules with the NM-HDV2 network module only.
When used with PVDM2 modules and either the built-in T1/E1 ports or the T1/E1 voice or WAN
interface cards (VWIC), the NM-HDV2 network module provides the interface to the PBX, the PSTN,
or WAN. The following VWICs are supported:
•
VWIC-1MFT-T1
•
VWIC-2MFT-T1
•
VWIC-2MFT-T1-DI
•
VWIC-1MFT-E1
•
VWIC-2MFT-E1
•
VWIC-2MFT-E1-DI
•
VWIC-1MFT-G703
•
VWIC-2MFT-G703
When used with PVDM2 modules and next-generation analog or BRI voice interface cards (VIC2), the
NM-HDV2 network module provides the interface to telephony equipment (PBX, key systems,
telephones, and fax machines) and to the PSTN. The following VICs are supported:
•
VIC-2DID
•
VIC-1J1
•
VIC-4FXS/DID (DID feature not supported)
•
VIC2-2FXO
•
VIC2-4FXO
•
VIC2-2FXS
•
VIC2-2E/M
•
VIC2-2BRI-NT/TE
