This topic describes the main concepts and view windows of Cisco Voice Routing Center (VRC) software.
VRC is designed so that you can make dial plan changes for either the:
Administrative Domain (AD) - The whole network. The highest level of administration which encompasses the entire dial plan. The AD includes all elements that participate in the VoIP call routing.
Regions - A specific partition of the network. It may contain one or more zones, gatekeeper groups, and directory gatekeepers.
Note: There can be only one design session open per region, but through regional administration, multiple users can be doing regional designs. Only one user at a time can do an AD level design, and that design session blocks any regional design session.
A scope is the area managed by the network administrator. A design scope can be the entire AD or a region.
A scope is a logical construct used to organize the network through the VRC and does not correspond to a physical apparatus.
VRC Version 1.2 uses CNS security services for user administration and authorization.
VRC has three distinct modes of operation, called views. Each view provides different capabilities for managing a dial plan.
Baseline View - This view represents the current dial plan. Ideally the baseline is consistent with the physical network but can differ if the dial plan changes are made outside of VRC. Execute the Discovery operation to update the baseline dial plan so that it reflects the dial plan on the physical network.
Topology View - This view is where you identify the set of elements that can participate in a dial plan. The VRC Topology View identifies the partitioning of those elements into regions which can be independently managed.
Note: When integrated with PTC, VRC uses the PTC Topology Manager. The VRC Topology View is not accessible from the VRC client.
Design View - This view is where you make changes to an existing dial plan. This includes introducing network elements with no previous dial plan configurations into a dial plan design. To update the baseline dial plan and configurations for the added elements, you must commit the dial plan design. You can also start a new dial plan design session in the Design View.
