Cisco EM3-HDA-8FXS/DID

The Cisco EM3-HDA-8FXS/DID is a voice interface card (VIC) module designed for use with Cisco Integrated Services Routers (ISRs). It provides connectivity for up to 8 analog Foreign Exchange Station (FXS) or Direct Inward Dialing (DID) ports. The FXS ports allow connection to analog devices such as analog phones, fax machines, or modems, enabling them to be integrated into a VoIP network. The DID ports, on the other hand, allow direct inward dialing, which enables callers to directly reach an internal extension without going through a receptionist or an automated attendant. The EM3-HDA-8FXS/DID module is typically used in small to medium-sized businesses or branch offices that require analog connectivity for their communication needs. It offers flexibility and scalability for voice services, allowing organizations to leverage their existing analog devices while transitioning to IP-based telephony.
