About Network Regions, Sites, and Subnets

 

Topic Last Modified: 2010-11-10

The advanced Enterprise Voice features described in this section share certain configuration requirements for network regions, network sites, and subnets. For example, all three advanced features require that each subnet in your topology be associated with a specific network site, and each network site must be associated with a network region.

importantImportant:
Before you begin network configuration for call admission control, E9-1-1, or media bypass, ensure that you reviewed additional information about network settings in the Network Settings for the Advanced Enterprise Voice Features topic in the Planning documentation. For details about network configuration primarily about call admission control, also see Planning for Call Admission Control in the Planning documentation.

Call admission control and E9-1-1 have additional configuration requirements for network sites:

  • Call admission control requires that a bandwidth policy profile be specified for each site that is constrained by WAN bandwidth limitations. If you plan to deploy call admission control, you must Create Bandwidth Policy Profiles before you configure your network sites.
  • E9-1-1 requires that a location policy be specified for each site. If you plan to deploy E9-1-1, you must Create Location Policies before you configure your network sites.

The following topics provide steps to create or modify network regions and network sites, and to associate subnets with network sites. These topics are not specific to any particular advanced Enterprise Voice feature.
