The Cisco High Density VoiceFax Network Module (Part Number: EM-HDA-3FXS/4FXO) is a versatile voice and fax solution designed to be used with Cisco routers. This module provides a combination of voice and fax functionalities with both FXS and FXO ports. Specifically, it features 3 FXS ports and 4 FXO ports, allowing efficient handling of voice, fax operations, as well as connections to both Public Switched Telephone Network (PSTN) lines and customer premises equipment (CPE).
The FXS (Foreign Exchange Station) ports are designed to connect directly to analogue devices such as telephones, fax machines, or modems, while the FXO (Foreign Exchange Office) ports connect to the PSTN for receiving and making external calls. This high-density design is suitable for businesses that require flexibility and reliable connections between internal voice systems and external telephone lines. The module helps increase communication capabilities, combining both voice and fax transmissions seamlessly within a single device.
Constructed and integrated to work with Cisco ISR (Integrated Services Router) platforms, the Cisco EM-HDA-3FXS/4FXO module enhances overall system performance with its voice compression and echo cancellation features. Moreover, it supports a variety of signalling protocols such as Dual-Tone Multi-Frequency (DTMF) detection, Call Feature processing, and T.38 fax relay, making it an excellent choice for environments handling high volumes of voice/fax traffic.
The module allows businesses to facilitate clearer voice calls and efficient fax transactions, boasting high voice quality with low latency. It ensures compatibility with key Cisco systems and a range of telephony standards.
