Cisco EM-HDA-6FXO

The Cisco EM-HDA-6FXO is an expansion module that can be installed in certain Cisco voice gateways and routers. It provides six additional Foreign Exchange Office (FXO) ports, which are used to connect analog telephone lines to the gateway or router. These FXO ports allow the gateway or router to interface with traditional analog telephony systems, such as PSTN (Public Switched Telephone Network) lines or analog PBX systems. The EM-HDA-6FXO module expands the connectivity options of the Cisco device, enabling it to handle more analog phone lines for voice communication.
