Network regions are the network hubs or backbones used in the configuration of call admission control, E9-1-1, and media bypass. Use the following procedures to create or modify network regions. For example, if you have already created network regions for one Voice feature, you do not need to create new network regions; other advanced Enterprise Voice features will use those same network regions. You may, however, need to modify an existing network region definition to apply feature-specific settings. For example, if you have created network regions for E9-1-1 (which do not require an associated central site) and you then deploy call admission control, you need to modify the network region definitions to specify a central site. For more information, see Configure Network Regions for CAC.

Note:
Any feature-specific requirements for network region definitions are documented in the Deployment topics for the feature. For example, network regions must be defined for media bypass. However, media bypass cannot use any network configurations—network region or otherwise—unless you have defined the network regions, sites, and subnets for call admission control, as well as enabled call admission control for use.

For more information about working with network regions, see the Communications Server Management Shell documentation for the following cmdlets:

Create a Network Region

Create a network region that can be used by call admission control, E9-1-1, or media bypass.

To create a network region using Management Shell

  1. Open Communications Server Management Shell.

  2. Run the New-CsNetworkRegion cmdlet to create network regions:

    Copy Code 
    New-CsNetworkRegion –Identity <String> -CentralSite <String>

    For example:

    Copy Code 
    New-CsNetworkRegion –Identity NorthAmerica -CentralSite CHICAGO-NA-MCS-DEPLOYMENT -Description “All North America Locations”

    In this example, you created a network region called “NorthAmerica” that is associated with a central site with site ID “CHICAGO-NA-MCS-DEPLOYMENT”.

  3. To finish creating network regions for your topology, repeat step 2 with settings for each network region.

To create a network region using Control Panel

  1. Open Communications Server Control Panel.

  2. In the left navigation bar, click Network Configuration.

  3. Click the Region navigation button.

  4. Click New.

  5. On the New Region page, click Name and then type a name for the network region.

  6. Click Central site, and then click a central site in the list.

  7. Optionally, click Description, and then type additional information to describe this network site.

  8. Click Commit.

  9. To finish creating network regions for your topology, repeat steps 4 through 8 with settings for other regions.

Modify a Network Region

Modify settings for an existing network region to accommodate changes to the basic region information or changes required by a new feature.

To modify a network region using Management Shell

  1. Open Communications Server Management Shell.

  2. Run the Set-CsNetworkRegion cmdlet to modify an existing network region:

    Copy Code 
    Set-CsNetworkRegion –Identity <String> -CentralSite <String>

    For example:

    Copy Code 
    New-CsNetworkRegion –Identity NorthAmerica -CentralSite CHICAGO-NA-MCS-DEPLOYMENT -Description “North American Region”

    In this example, you modified an existing network region called “NorthAmerica” (created using the procedures earlier in this topic) by changing the description. If a description existed for the “NorthAmerica” region, this command overwrites it with this value; if no description had been set, then this command sets it.

  3. To modify other network regions, repeat step 2 with settings for other regions.

To modify a network region using Control Panel

  1. Open Communications Server Control Panel.

  2. In the left navigation bar, click Network Configuration.

  3. Click the Region navigation button.

  4. In the table, click the network region that you want to modify.

  5. Click Edit, and then click Show details….

  6. On the Edit Region page, change the values for this network region’s settings as appropriate.

  7. Click Commit.

  8. To finish modify network regions, repeat steps 4 through 7 with settings for other regions.
