Cisco High-Density Analog Voice/Fax Network Module

Cisco 2600 and 3600 high-density analog voice/fax network modules provide enterprises, managed service providers and service providers the ability to directly connect the PSTN and legacy telephony equipment to existing Cisco 2600 and Cisco 3600 routers. This provides immediate multiservice advantages, such as telephony toll bypass, new packet telephony applications, and full gateway integration within a Cisco AVVID (Architecture for Voice Video and Integrated Data) IP telephony architecture. The voice/fax modules for the Cisco 2600 and Cisco 3600 Series multiservice access routers enable packet voice technologies including voice over IP (VoIP), voice over Frame Relay (VoFR) and voice over ATM (VoATM). Cisco voice solutions provide the means for integrating both voice and data within a single network allowing users to take advantage of services, such as toll-bypass, without sacrificing voice quality. Cisco IOS Software also incorporates built-in quality-of-service (QoS) features along with standards-based encapsulation and fragmentation, providing efficient direct transport of voice and fax over IP, Frame Relay, and ATM networks. These Cisco IOS solutions enable time-sensitive voice traffic to be moved across even low-bandwidth WAN connections with the priority and quality that voice/fax demands. Transporting voice over IP networks continues to provide transport flexibility since IP can be routed across a multitude of WAN technologies (leased lines, Frame Relay, and ISDN) along with providing direct connectivity to the desktop.
