Cisco Evm-hd 8fxs/did High Density Voice/ Fax Extension Module- New
The High-Density Analog (FXS/DID/FXO) and Digital (BRI) Extension Module for Voice/Fax (EVM-HD) feature delivers a higher-density integrated analog/digital voice interface. The EVM-HD-8FXS/DID baseboard network module provides eight Foreign Exchange Station (FXS) or direct inward dialing (DID) ports. This network module accesses digital signal processor (DSPs) modules on the motherboard, instead of using onboard DSPs. You can increase the port density by plugging in up to two optional expansion modules in any combination:
- EM-HDA-8FXS--8-port FXS voice/fax expansion module
- EM-HDA-3FXS/4FXO--3-port FXS and 4-port FXO voice/fax expansion module
- EM-HDA-6FXO--6-port FXO voice/fax expansion module
- EM-4BRI-NT/TE--4-port ISDN BRI expansion module
PVDM2 DSP modules are used in combination with the EVM-HD-8FXS/DID baseboard and its expansion modules. PVDM2 modules are available separately and installed in the DSP module slots located inside the router chassis.
