Updated August 2002

Cisco 2600, 3600, and 3700 low density 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, Cisco 3600, and Cisco 3700 routers. This provides immediate multiservice advantages,

such as telephony toll bypass, new packet telephony applications, and full gateway integration within a Cisco

AVVID architecture.

The low density voice/fax network modules for the Cisco 2600, 3600, and 3700 series multiservice access routers

enable packet voice technologies including VoIP (H.323, MGCP and SIP), VoFR and VoATM (AAL5). 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. This combination of voice solutions

leverages the Cisco proven track record of being able to effectively handle time-sensitive traffic, such as Systems

Network Architecture (SNA) over IP networks. Cisco IOS® software also incorporates built-in quality-of-service

(QoS) features along with standards-based encapsulation providing efficient direct transport of both 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 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 ATM ) along with providing direct connectivity to the desktop.

The low density voice/fax network modules slide into Cisco 2600, 3600, and 3700 network module slots and contain

either one or two voice interface card (VIC) slots. The VICs are daughter cards that slide into the voice/fax network

modules and provide the interface to the telephony equipment and the PSTN. Just as the Cisco WAN interface cards
