In this section:
The SBC 5100, SBC 5110, SBC 5200, and SBC 5210 platforms are no longer supported beginning with the SBC Core 10.0.0R0 release. This release supports SBC 5400/7000/SWe/Cloud Native edition (CNe) platforms. Contact Ribbon Sales for upgrade information.
IMPORTANT
Zone CAC
Use the zone CAC parameters to configure call admission control (CAC) settings for a zone on ingress, on egress, and for the zone as a whole.
Command Syntax
Note
Unless noted otherwise, the parameters/parameter values in this section apply to all SBC Core platforms.

Command Parameters
Zone CAC Parameters
Parameter | Length/Range | Description |
|---|---|---|
bandwidthLimit | 0-2147483647, or unlimited | Total bandwidth limit in Kbps/sec. |
bandwidthLimitThreshold | 0-100 | Bandwidth utilization notification threshold, as a percentage. (default = 0) |
bandwidthVideoThreshold | 0-100 | Enter threshold value (as a percentage of video bandwidth) to limit video streams to a specific bandwidth to prevent video calls consuming call bandwidth otherwise needed for audio calls. (default = 0) |
callLimit | 0-2147483647, or unlimited | Total number of calls allowed on this zone. (default = 'unlimited') |
callLimitThreshold | 0-100 | Call limit utilization notification threshold, as a percentage. (default = 0) |
egress | N/A | Egress-specific call admission control configuration. See the Egress Parameters table below for details. |
emergencyOversubscription | 0-1000, or unlimited | This parameter gives priority treatment to emergency calls by specifying the resource over-subscription percentage allowed for emergency calls, and represents the allowed percentage of emergency calls beyond the configured call limit. When the call limit is reached, normal calls are rejected but emergency calls are accepted up to an expanded limit. (default = 10) |
extendedEmergencyIpLimit | 0-40000 | Additional number of emergency calls (expressed as a numeric value) allowed if call limit and emergency over-subscription quota are exhausted. (default = 0) |
hpcOversubscription | 0-100 | This 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) |
| N/A | Ingress-specific call admission control configuration. See the Ingress Parameters table below for details. |
registrationLimit | 0-2147483647, or unlimited | The number of concurrent registrations allowed in this zone. (default = 'unlimited') |

Command Parameters
Egress Parameters
| Parameter | Length/Range | Description |
|---|---|---|
callBurstMax | SBC 7000: 1-2700, or unlimited | Maximum allowed burst (above the allowed sustained rate) for egress call attempts, in calls/second. (default = 'unlimited') |
callLimit | 0-2147483647, or unlimited | Total number of outbound concurrent calls allowed. (default = 'unlimited' ) |
callRateMax | SBC 7000: 1-1350, or unlimited | Maximum sustained egress call rate allowed in calls/second. (default = 'unlimited') Note: You can set both |
emergencyOversubscription | 0-1000 | Over-subscription of resources (as a percentage) allowed for emergency calls. (default = 10) |
extendedEmergencyIpLimit | 0-40000 | Additional number of emergency calls (expressed as a numeric value) allowed if call limit and emergency over-subscription quota are exhausted. (default = 0) |
hpcOversubscription | 0-100 | This 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) |
registerBurstMax | SBC 5400: 1-1500 or unlimited SBC 7000: | Specifies the maximum allowed egress burst (above the allowed sustained rate) for initial SIP registrations. The default value is unlimited. |
| SBC 5400: 1-1500 or unlimited SBC 7000: | Specifies the maximum allowed sustained egress rate (registrations per second) for initial SIP registrations. The default value is unlimited. Note: You can set both “registerBurstMax” and “registerRateMax” as unlimited; however, if you assign a value to one parameter, the other must also be assigned a value. |
