Cisco EVM-HD-8FXS/DID w/ 2x EM-HDA-6FXO High Density Voice Fax Extension Module

Description

EVM-HD-8FXS/DID
The Cisco High-Density Extension Module for voice and fax has 8 FXS and DID ports. Individual ports on the baseboard module can be configured for FXS or DID signaling. Adjacent ports should share the same configuration to avoid impedance setting conflicts. A change to the impedance setting for one port, changes the setting on the adjacent port. Paired ports are: 0 and 1; 2 and 3; 4 and 5; 6 and 7.
An on-premises FXS interface connects directly to a standard telephone, fax machine, or similar device and supplies ring, voltage, and dial tone. Signaling support available in FXS mode includes loop-start and ground-start. DID trunks from the central office can be connected to the Cisco High-Density Extension Module baseboard for off-premises connections. Signaling support available in DID mode includes immediate, delay dial, and wink start.
Users plug in up to two expansion modules in any combination to increase the voice and fax capacity of the Cisco High-Density Extension Module baseboard.
EM-HDA-6FXO
This 6-port FXO voice and fax expansion module provides off-premises connection to the central office. This module supports FXO power failover. If power to the router fails, this feature helps enable a direct metallic path between an FXO port and a special "red". It also supports analog Centralized Automated Message Accounting (CAMA) on any port. telephone to provide a direct line to the PSTN.
