In this section:
Use this object to configure Gateway Trunk Group parameters.
Note
The SBC 7000 system supports creating IP Interface Groups containing sets of IP interfaces that are not "processor friendly" (i.e. carried on physical Ethernet ports served by separate processors). However, restrictions exist regarding the usage of such Interface Groups.
(This ability does not apply to the SBC 5400 system which have only two physical media ports. IP interfaces from the two physical ports may be configured within the same IP Interface Groups without restrictions.)
For complete details, refer to Configuring IP Interface Groups and Interfaces.
To View Gw Trunk Group
On SBC main screen, navigate to All > Address Context > Zone > Gw Trunk Group. The Gw Trunk Group can be checked for each Address Context and Zone or for all the Address Contexts and Zones created. Use the drop-down box to select the desired Address Context and Zone.
The Gw Trunk Group window is displayed:

To Edit Gw Trunk Group
To edit any of the Gw Trunk Group in the list, click the radio button next to the specific Gw Trunk Group name.
The Edit Selected Gw Trunk Group window is displayed.
Make the required changes and click Save at the right hand bottom of the panel to save the changes made.
To Create Gw Trunk Group

The following fields are displayed:
Table 1: Gw Sig Trunk Group Parameters
Parameter | Description |
|---|---|
| Specifies the name of the Gateway Trunk Group. |
| The administrative state of the gateway trunk group:
|
| The operational mode of the gateway trunk group:
|
| The action when putting this gateway trunk group out Of Service. This object controls whether calls are forced off or allowed to dry up upon a mode out-of-service. Select any one of the option:
|
| Dry up timeout (in minutes) when this gateway trunk group is out Of Service with dry up action. Enter a value in the range of 0-1440. Default is 5 minutes. |
| The percentage of calls to continue to send to a remote congested gateway (in MC1). Enter value in range of 0-100 percent. Default is 90 percent. |
| The percentage of calls to continue to send to a remote congested gateway (in MC2). Enter value in range of 0-100 percent. Default is 70 percent. |
| Specifies the automatic congestion control timer. Enter value in range of 0-10. Default is 0. |
Parent Shared CAC Limits Pool Name | Name of an existing Shared CAC Limits Pool that you assign as the parent of the Gateway Trunk Group. |
Packet Outage | |
| This is the outage (in milliseconds) on a call for that call to be counted as part of the packet outage detection algorithm. Enter value in range of 0-65535 in milliseconds. Default is 6000 milliseconds. |
| The number of calls with outages required within the current interval to declare a packet outage event. Enter value in range of 0-65535. Default is 1000. |
| The amount to reduce the bandwidth limit (as a percentage of the configured limit) when a packet outage is detected. Enter value in range of 0-100 percent. Default is |
| Used to enable automatic bandwidth reduction when a packet outage is detected. Select any one of the option:
|
| The size of the packet outage detection interval in minutes. Enter value in range of 5- 1440 minutes. Default is 15 minutes. |
| Call Reservation | |
| The percent of channels reserved for inbound calls in IP gateway trunk groups. Must be 0-100, in increments of 5. Default is 0. |
| The administrative state of the packet outage:
|
| The number of priority call resources (circuits or IP calls) to be reserved for this trunk group. Must be 0-100, default is 1. |
| The number of incoming call resources (circuits or IP calls) to be reserved for this trunk group. Must be 0-128, default is 1. |
| The percentage of outgoing call resources (circuits or IP calls) to be reserved for this trunk group. This percentage is applied to the total number of circuits less the circuits reserved for incoming calls less the circuits reserved for priority calls. Must be 0-100, default is 10%. |
| SILC | |
| The Administrative state of the SILC traffic control. Select any one of the option:
|
| The percentage of calls to accept when the machine congestion level is 1. Enter value in range of 0-100 percent. Default is 75. |
| The percentage of calls to accept when the machine congestion level is 2. Enter value in range of 0-100 percent. Default is 25. |
| CAC | |
Call Limit | Total number of concurrent calls (0-2147483647, or unlimited), either ingress or egress, that are allowed (default=Unlimited). |
Bandwidth Limit | The total media bandwidth limit (0-2147483647, or unlimited), in Kbits/sec (default=Unlimited). |
Emergency Oversubscription | The percentage (0-1000) of resource oversubscription allowed for emergency calls (default=10). |
Hpc Oversubscription | This parameter specifies the amount of resource over-subscription as a percentage (0-100), that is allowed for HPC. When the baseline call limit and bandwidth limit are reached, normal calls are not admitted, but additional HPC are allowed up to the configured percentage value (default=10). |
| Egress | |
Call Limit | Total number of concurrent calls (0-2147483647, or unlimited) that are allowed on egress (default=Unlimited). |
Emergency Oversubscription | The percentage (0-1000) of resource oversubscription allowed for emergency calls (default=10). |
Hpc Oversubscription | This parameter specifies the amount of resource over-subscription as a percentage (0-100), that is allowed for HPC. When the baseline call limit and bandwidth limit are reached, normal calls are not admitted, but additional HPC are allowed up to the configured percentage value (default=10). |
Call Rate Max | Maximum (SBC 7000: Note: You can set both |
Call Burst Max | Maximum (SBC 7000: 1-2700, or unlimited) allowed burst size (above the allowed sustained rate) for ingress call attempts, in calls per second (default=unlimited). |
| Ingress | |
Call Limit | Total number of concurrent calls (0-2147483647, or unlimited) that are allowed on ingress (default=Unlimited). |
Emergency Oversubscription | The percentage (0-1000) of resource oversubscription allowed for emergency calls (default=10). |
Hpc Oversubscription | This parameter specifies the amount of resource over-subscription as a percentage (0-100), that is allowed for HPC. When the baseline call limit and bandwidth limit are reached, normal calls are not admitted, but additional HPC are allowed up to the configured percentage value (default=10). |
Call Rate Max | Maximum (SBC 7000: Note: You can set both |
Call Burst Max | Maximum (SBC 7000: 1-2700, or unlimited) allowed burst size (above the allowed sustained rate) for ingress call attempts, in calls per second (default=unlimited). |
| Media | |
| Interface group to be used for media. |
| If enabled, filter out incoming media packets which do not match the expected source IP address and UDP port. |
| Specifies whether to enable the direct-media path so that media flows directly between endpoints in the same direct-media group or not. The options are:
|
Note
Call policing, using Call Rate Max and Call Burst Max, is applicable only to normal and emergency calls, and not to high priority calls (HPC).
