1. High-complexity vocoders supported: G.711, G.726, G.729, G.723.1, G.728, and Fax Relay.
2. Medium-complexity vocoders supported: G.711, G.726, G.729a, and Fax Relay.
3. Flexi vocoders supported: G.711, G.726, G.729, G.723.1, G.728, and Fax Relay (number of channels depends on codec
selected).
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
