The Cisco WS-U4604-8FXS is a modular interface card designed for extending voice and fax capabilities within Cisco systems. It offers support for up to eight FXS (Foreign Exchange Station) ports, enabling connections to analog devices such as telephones, fax machines, and modems. These ports function by allowing legacy analog devices to connect to a VoIP system, which makes this module ideal for businesses transitioning from traditional telephony to VoIP solutions while retaining the use of existing infrastructure.
The module maintains high compatibility with Cisco Catalyst switches and routers, allowing for flexible networking configurations within a variety of environments. By supporting media gateway functionality, the WS-U4604-8FXS is capable of converting analog signals into digital for processing by a VoIP network, ensuring smooth communication between disparate systems.
Equipped with FXS interfaces, this card ensures local service even when interacting with a central VoIP system. The benefit of using FXS ports is the ability to connect phones, modems, or fax machines directly. Additionally, this card can assist businesses aiming to maximize existing legacy telecommunication equipment without the need for immediate and costly hardware upgrades.
The WS-U4604-8FXS also offers advanced echo cancellation features and digitisation improvements, supporting a wide range of voice signalling protocols. These capabilities provide a reliable, efficient, and flexible solution for companies migrating from traditional PBX systems to IP telephony.
