Cisco Packet Telephony Center (PTC) is a management solution for large-scale H.323 networks. PTC manages the network through Element Management Systems (EMS) or through a Cisco IE2100 device.
PTC provides overall configuration management of the network. When integrated with PTC, VRC becomes a module within PTC that provides for H.323 dial plan management.
When you are using VRC as an integrated module of PTC:
VRC is launched from the PTC user interface.
Network topology operations are managed through the PTC Topology Manager. These include adding and deleting regions and network elements from the topology. The VRC Topology View is not accessible from the VRC client.
When you make changes to a dial plan and commit the design, any topology update, such as adding a gateway to a zone, is automatically reflected in the PTC Topology Manager.
Changes to network elements through PTC are sent to VRC as events and the elements affected by the change are flagged in the VRC Baseline View and Design View. Refer to Adding a Managed Resource to a Gateway.
