More Specifications

This Product is a voice interface card that is used in Cisco routers to provide analog telephone ports. The card has 4 FXS (Foreign Exchange Station) ports and 1 DID (Direct Inward Dial) port. The FXS ports are used to connect analog telephones to the router, while the DID port is used to connect to a PSTN (Public Switched Telephone Network) line.

Each FXS port provides an interface for an analog telephone or fax machine. It allows the telephone or fax machine to send and receive audio and signaling information to and from the PSTN. The DID port, on the other hand, is a feature that enables users to make a direct call from the PSTN to a specific extension number without the need to go through an operator.

This Product is a plug-in module, which means it can be easily inserted into a compatible Cisco router. It is designed for high performance, and it's ideal for small-to-medium-sized businesses, small-to-medium-sized enterprise branch offices, and other organizations that need to connect a small number of analog phones or fax machines to a Cisco IP telephony solution.
