The model Cisco 2 Ports Voice Interface Card is a hardware component that can be installed in certain Cisco routers to provide analog telephone connectivity. It is designed for small-scale voice-over-IP (VoIP) deployments and allows the router to connect to traditional analog telephones, fax machines, or other analog devices.
Here are some key features of the VIC-2FXS:
2 FXS ports: Provides two Foreign Exchange Station (FXS) ports, which are interfaces that allow analog devices to connect to a telephone network.
Voice quality: The model supports G.711, G.729, and G.723.1 codecs for high-quality voice transmission.
Compatibility: This item is compatible with Cisco routers that support the VIC slot, such as the 1800, 2800, and 3800 series routers.
Configuration: The model can be configured through the Cisco IOS command-line interface (CLI) or through a web-based graphical user interface (GUI).
This item is a cost-effective solution for small-scale VoIP deployments that require analog telephone connectivity. It is easy to install and configure, and it offers high-quality voice transmission using industry-standard codecs.
Performance and Reliability
The model Cisco 2 Ports Voice Interface Card is designed to provide reliable and high-performing analog telephone connectivity for small-scale voice-over-IP (VoIP) deployments. The performance and reliability of the VIC-2FXS is affected by several factors, including:
Codecs: The model supports G.711, G.729, and G.723.1 codecs for voice compression and transmission. These codecs are widely used in the industry and provide high-quality voice transmission.
Latency: Latency is the time it takes for a packet of data to travel from the sender to the receiver. The model has low latency, which means that voice transmissions are transmitted in real-time with minimal delay.
Jitter: Jitter is the variation in the time between packets arriving. The model uses jitter buffers to smooth out jitter and ensure that voice transmissions are transmitted smoothly.
Packet loss: Packet loss occurs when one or more packets of data do not reach their destination. The model uses error-correction algorithms to minimize packet loss and ensure that voice transmissions are transmitted accurately.
