Cisco 6 Port FXO Voice and Fax Expansion Module
Provide an additional six ports of voice and fax devices on your network within your Integrated Services Router using this refurbished Cisco EM-HDA-6FXO Voice-over-IP expansion module. This device is able to be installed in a variety of ISR units using the Cisco 2900 and 3900 High-Density extention module compatible series of routers. This voice/fax expansion module will upgrade your network to utilize six additional connections to the public switched telephone network – sometimes referred to as POTS. 

This module can be used in conjunction with a PBX mainframe of an establishment in order to provide additional connectivity to outside telephone usage. Using a RJ-21 connector, the Cisco EM-HDA-6FXO connects to the main distribution node of your network. This plugin module then connects the PBX of the network to the PSTN for use.

In the event of power failure within the router that this refurbished EM-HDA-6FXO module is plugged into, the FXO power failover feature is activated, which provides a direct line to the PSTN in order to reduce down time. However, this feature only creates the patch in order to provide telephone services. Other integrated services of the router that this unit is attached to will still be unavailable until power is restored.
