Voice over ATM Switched Virtual Circuits on the Cisco MC3810 1Voice over ATM Switched VirtualCircuits on the Cisco MC3810This document describes voice over Asynchronous Transfer Mode (VoATM) switched virtualcircuits (SVCs) for the Cisco MC3810 multiservice access concentrator.This document includes the following sections:• Feature Overview, page 1• Supported Platforms, page 4• Supported Standards, MIBs, and RFCs, page 4• Prerequisites, page 4• Configuration Tasks, page 5• Troubleshooting Voice over ATM SVCs, page 16• Monitoring and Maintaining Voice over ATM SVCs, page 19• Configuration Examples, page 20• Command Reference, page 22• Glossary, page 30Feature OverviewVoATM SVCs allow the Cisco MC3810 to transfer voice data dynamically and as needed—withouttying up the resources required for static, manually provisioned permanent virtual circuits (PVCs).An SVC connection is initiated for each call, and each request includes bandwidth andquality-of-service (QoS) information required for the connection. SVCs are ideal for networks thatare highly interconnected, where scalability is essential, and in situations where traffic is sporadic.In addition, service providers often offer more advantageous, usage-based pricing options for SVCs.VoATM using SVCs on the Cisco MC3810 includes all of the voice features that the Cisco MC3810supports for PVCs and for Frame Relay transport. Like other Cisco voice implementations, VoATMusing SVCs is based on dial peers and uses ATM Adaptation Layer 5 (AAL5).ATM SVC service operates much like X.25 SVC service, although ATM allows much higherthroughput. It requires a signaling protocol between a router or a multiservice access concentratorand an ATM switch. The ATM signaling software provides a method of dynamically establishing,maintaining, and clearing ATM connections at the User-Network Interface (UNI). In UNI, the routerserves as the user and the ATM switch is considered the network. The router does not performcall-level routing. Instead, the ATM switch does the ATM call routing, and the router directs packetsthrough the resulting circuit.
