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.
Recommended Hardware Configuration for Cisco PTC and Cisco VRC
The minimum platform recommendations for the Cisco PTC and Cisco VRC applications are provided
in Table 2-1.
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 2-7 illustrates the element details of the MGC node and the CMNM
applications server(s).
Figure 2-7 provides the details of the network elements that comprise the PGW 2200 and CMNM.
