Description
The Cisco VIC3-2EM is a high-performance Voice Interface Card designed for Cisco ISR routers, offering two Foreign Exchange Office (FXO) or Foreign Exchange Station (FXS) ports for analog voice connectivity. Built for versatility, this module supports both voice and fax applications, making it ideal for small to medium-sized businesses looking to integrate legacy analog devices into modern VoIP infrastructures. Its compact design ensures seamless integration into compatible Cisco routers, such as the 2800 and 3800 Series, without compromising valuable rack space. The card is hot-swappable, allowing for easy installation and maintenance without interrupting network operations.
Technically, the VIC3-2EM supports a range of signaling protocols, including loop-start and ground-start signaling, and is compatible with Cisco IOS software for advanced call routing and voice management. It features an onboard Digital Signal Processor (DSP) that enables echo cancellation and tone detection, ensuring clear and reliable voice communication. Each port can be configured independently, allowing deployment flexibility in mixed analog environments. When purchasing used, buyers should verify port condition and DSP functionality to ensure optimal performance in their network setup.
