The purpose of this feature is to allow associating an existing Gateway Trunk Group with an existing Shared CAC Limits Pool, so that the basic call control parameters of a Gateway Trunk Group like call limit and bandwidth limit can be set, modified or deleted easily.

Associating a Gateway Trunk Group with an Existing Shared CAC Limits Pool

Perform the following steps to associate an existing Gateway Trunk Group with an existing Shared CAC Limits Pool:

Note

Step 1 and 2 are prerequisites for attaching a Gateway Trunk Group with a Shared CAC Limits Pool, and configuring the CAC parameters of the Gateway Trunk Group. If the required Shared CAC Limits Pool and Gateway Trunk Group exists, skip step 1 and 2.

  1. Create a Shared CAC Limits Pool: Refer to Shared CAC-Limits Pool - CLI. For this example, we refer it as Cac1.
  2. Create a Gateway Trunk Group: Refer to Zone - GW Trunk Group - CLI. For this example, we refer it as gwtg1.
  3. Attach the Gateway Trunk Group as a child of the Shared CAC Limits Pool:

    % set addressContext default zone defaultSigZone gwTrunkGroup gwtg1 parentSharedCacLimitsPoolName Cac1 
    % commit
  4. Configure the CAC related parameters and sub-parameters of the Gateway Trunk Group:

    Note

    The example pertaining to this step are instances of possibilities for a SBC 5000 series hardware server, but are also valid for SBC 7000. However, for some of the parameters, SBC 7000 offers wider range of possible values. For more information on the variances of possible values for SBC 5000 and 7000 series hardware, refer to Zone - GW Trunk Group - CLI.

    % set addressContext default zone defaultSigZone gwTrunkGroup gwtg1 cac 
    	bandwidthLimit 1000000000
    	callLimit 2000000000
    	egress
    		callBurstMax 500
    		callLimit 1000000000
    		callRateMax 200
    		emergencyOversubscription 300
    		hpcOversubscription 50
    	emergencyOversubscription 400
    	hpcOversubscription 80
    	ingress
    		callBurstMax 450
    		callLimit 500000000
    		callRateMax 100
    		emergencyOversubscription 100
    		hpcOversubscription 30
    
    % commit

Deleting the CAC Parameters from the Trunk Group

  • To delete a CAC related parameter (or sub-parameter) from the Gateway Trunk Group:

    % delete addressContext default zone defaultSigZone gwTrunkGroup gwtg1 cac bandwidthLimit
    % commit
    % delete addressContext default zone defaultSigZone gwTrunkGroup gwtg1 cac ingress callLimit
    % commit

    Note

    If you delete the cac parameters egress and ingress, then configuration of their sub-parameters are automatically deleted.

  • Delete all CAC related parameter (and sub-parameters) of the Gateway Trunk Group:

    % delete addressContext default zone defaultSigZone gwTrunkGroup gwtg1 cac
    % commit

Detaching the Gateway Trunk Group

Detach the Gateway Trunk Group from the Shared CAC Limits Profile:

% delete addressContext default zone defaultSigZone gwTrunkGroup gwtg1 parentSharedCacLimitsPoolName
% commit
