This page describes CLI syntax and parameters for the gateway trunk group 'Call Admission Control' object.

Note

As a best practice, always use UPPERCASE for trunk group names.

 

Note

Unless annotated otherwise, the parameter values in this section apply to the SBC Core.

GW Trunk Group CAC

Command Syntax

% set addressContext <name> zone <name> gwTrunkGroup <name> cac
	bandwidthLimit <0-2147483647>
	callLimit <0-2147483647>
	egress 
	emergencyOversubscription <0-1000>
	hpcOversubscription <0-100>
	ingress

Command Parameters

Table : SIP Trunk Group CAC Parameters

ParameterLength/RangeDescription
bandwidthLimit0-2147483647, or unlimitedThe total media bandwidth limit, in Kbits/sec. (default = "unlimited")
callLimit0-2147483647, or unlimitedTotal number of concurrent calls (either ingress or egress) allowed. (default = “unlimited”).
egressN/AEgress-specific call admission control configuration for the gateway trunk group. See Egress Parameters table below for details.
emergencyOversubscription0-1000

The percentage of resource oversubscription allowed for emergency calls. (default = 10)

hpcOversubscription0-100This parameter specifies the amount of resource over-subscription (as a percentage) allowed for HPC calls. When the baseline call limit and bandwidth limit are reached, normal calls are not admitted, but additional HPC calls are allowed up to the configured percentage value. (default = 10)
ingressN/AIngress-specific call admission control configuration for the gateway trunk group. See Ingress Parameters table below for details.

 

Egress

Command Syntax

% set addressContext <name> zone <name> gwTrunkGroup <name> cac egress 
	callBurstMax <1-900> (SBC 7000 range is 1-2700)
	callLimit <0-2147483647>
	callRateMax <1-450> (SBC 7000 range is 1-1350)
	emergencyOversubscription <0-1000>
	hpcOversubscription <0-100>

Command Parameters

Cal policing using callRateMax and callBurstMax is applicable only to normal and emergency calls, not to high priority calls (HPC).

Table : Egress Parameters

ParameterLength/RangeDescription
callBurstMax

SBC 5000: 1-900, or unlimited

SBC 7000: 1-2700, or unlimited

Maximum allowed burst size (above the allowed sustained rate) for egress call attempts, in calls per second. (default = 'unlimited')
callLimit0-2147483647, or unlimitedTotal number of concurrent calls (either ingress or egress) allowed on egress. (default = 'unlimited')
callRateMax

SBC 5000: 1-450, or unlimited

SBC 7000: 1-1350, or unlimited).

Maximum sustained egress call rate allowed in calls per second. (default = 'unlimited')

NOTE: You can set both callBurstMax and callRateMax as 'unlimited'; however, if you assign a value to one parameter, the other must also be assigned a value.

emergencyOversubscription  0-1000Over-subscription of resources (as a percentage) allowed for emergency calls. (default = 10)
hpcOversubscription0-100This parameter specifies the amount of resource over-subscription (as a percentage) allowed for HPC calls. When the baseline call limit and bandwidth limit are reached, normal calls are stopped, but additional HPC calls are allowed up to the configured percentage value. (default = 10)

Ingress

Command Syntax

Cal policing using callRateMax and callBurstMax is applicable only to normal and emergency calls, not to high priority calls (HPC).

% set addressContext <name> zone <name> gwTrunkGroup <name> cac ingress 
	callBurstMax <1-900> (SBC 7000 range is 1-2700)
	callLimit <0-2147483647>
	callRateMax <1-450> (SBC 7000 range is 1-1350)
	emergencyOversubscription <0-1000>
	hpcOversubscription <0-100>

Command Parameters 

Table : Ingress Parameters

ParameterLength/RangeDescription
callBurstMax

SBC 5000: 1-900, or unlimited

SBC 7000: 1-2700, or unlimited

Maximum allowed burst (above the allowed sustained rate) for ingress calls in calls per second. (default = 'unlimited')
callLimit0-2147483647, or unlimited

Total number of concurrent calls allowed on ingress. (default = 'unlimited')

callRateMax 

SBC 5000: 1-450, or unlimited

SBC 7000: 1-1350, or unlimited

Maximum sustained ingress call rate allowed in calls/second. (default = 'unlimited')

NOTE: You can set both callBurstMax and CallRateMax as 'unlimited'; however, if you assign a value to one parameter, the other must also be assigned a value.

emergencyOversubscription0-1000The amount of resource over-subscription (as a percentage) allowed for emergency calls. (default = 10)
hpcOversubscription0-100This parameter specifies the amount of resource over-subscription (as a percentage) allowed for HPC calls. When the baseline call limit and bandwidth limit are reached, normal calls are not admitted, but additional HPC calls are allowed up to the configured percentage value. (default = 10)
