Cisco Voice Routing Center

Cisco VRC is a GUI-based network management tool specifically designed for managing dial plans in a Voice over IP (VoIP) network.

Cisco VRC, version 1.1, is targeted for H.323-based networks. H.323 VoIP dial plans are statically configured and managed on gateway and gatekeeper platforms. The infrastructure of a typical H.323 VoIP network includes gateways and gatekeepers.

You can deploy Cisco VRC to discover the dial plan of an existing network. You can also use it to design new dial plans incorporating Cisco routers running as gateways, gatekeepers, and directory gatekeepers.

For a complete description, installation instructions, and Release Notes for the Cisco VRC application, refer to the “Related Documents” section.

Cisco Media Gateway Control Node Manager

CMNM integrates the management interfaces and management functionality of the PGW 2200 components into one comprehensive human interface and data repository. The PGW 2200 consists of the Cisco MGC host, one or more Cisco Signaling Link Terminals (Cisco SLTs) and the Cisco Catalyst 5500, Catalyst 2900 XL, or Catalyst 6509 LAN switch. CMNM provides fault, configuration, and performance management for all components of the Cisco MGC node.

CMNM provides the element-specific management features for the Cisco MGC node. It blends the management framework features of the Cisco Element Management Framework (Cisco EMF) with the individual interfaces and object structures of each managed element to produce an integrated management application. Figure 2-7illustrates the element details of the MGC node and the CMNM applications server(s).

Figure 2-7provides the details of the network elements that comprise the PGW 2200 and CMNM.
