Connecting Cisco Voice Network Modules to the Network

IP Communications High-Density Digital Voice or Fax Network Module

Connecting Cisco Voice Network Modules to the Network

You can install up to four PVDM2 modules on all of the NM-HDV2 SKUs. The number of channels

supported depends on the number and density-type of PVDM2 modules installed.

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

PVDM2-32 32-channel packet fax or voice DSP module

PVDM2-48 48-channel packet fax or voice DSP module

PVDM2-64 64-channel packet fax or voice DSP module
