Trunk Routing Action

Each Trunk Routing Action object is a child of a Trunk Routing Table object.

Each object contains information about a particular routing action in a routing table.


If you have an ISUP Media Channel defined for a one-way incoming trunk, do not specify this media channel in any Trunk Routing Action objects.



Note that when the grandparent Config Set is active, this object cannot be modified; all fields are read only and all actions are disabled. You must deactivate the grandparent Config Set before you can modify the object.

    Matches absence of address.
  • E.164
    Matches destination and source addresses.
  • Network ID
    Matches transit network addresses.
Address scope Change Scope of address used to match this action. This field is visible only if the Address type field is visible and set to E.164. Values:
  • Unknown
  • International
  • National
  • Subscriber

This field is visible only if the Routing table type field of the parent Trunk Routing Table is set to Destination address, Source address or Transit address and the Address type is not set to Not present and the Wildcard address type is Part wildcard header. The effective prefix length is used to determine the precedence of alternative wildcard address matches. If the effective prefix length is the same as the actual length of the wildcard address, set this field to zero. The default is zero.

Operator call match Change Specifies whether this action should match an operator call when the Routing table type field of the parent Trunk Routing Table is set to Operator call. This field is visible only if the Routing table type field of the parent Trunk Routing Table is set to Operator call. Values:
  • True
  • False
Call type match Change The call type used to match this action. This field is visible only if the Routing table type field of the parent Trunk Routing Table is set to Destination address, Source address or Transit address. Values:

    Used to match any call dialed using an 01 or 011 prefix
  • Match any
    Used to match any call type
Subscriber Group match Change The Subscriber Group used to match this action. This field is visible only if the Routing table type field of the parent Trunk Routing Table is set to Subscriber Group. Select from the list of configured Subscriber Groups or select one of the following values:
  • 0
    Match against a routing request that does not have an associated Subscriber Group.
  • Match any value
    Match against a routing request that has any Subscriber Group (or does not have an associated Subscriber Group).
Optional attributes to set Change Select which attributes are added to the routing request. The attributes selected in this field will affect the following fields. Select any combination of the following values:
  • AAR allowed
  • ARR allowed
  • Routing control (UK only)
  • Circuit code (North America only)
  • MF tandem routing code (North America only)
  • MF international non-operator routing code (North America only)
  • MF international operator routing code (North America only)
  • Max channel usage
  • Congestion level 1 acceptance probability
  • Congestion level 2 acceptance probability
AAR allowed Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. Attribute used internally to specify whether Automatic Alternative Routing is allowed if this action is chosen. If this field is set to True, the Routing Policy Services user may retry routing if media channel allocation fails. Values:
  • True (default)
  • False
ARR allowed Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. Attribute specifying whether Automatic Re-Routing is allowed if this action is chosen. If this field is set to True, the Routing Policy Services User may retry routing if signaling fails due to congestion at a subsequent exchange. Values:
  • True (default)
  • False
Routing control Change
  • This field is not valid in North America.
Circuit code Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. Attribute indicating the Circuit Code to be included in the routing request if this action is chosen. This parameter is used only if the call is routed to a transit network. Range : 0 - 15
MF tandem routing code Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. MF tandem routing code to be written back into the SETUP. This parameter is used only if the call is routed over MF signaling. Range: 0 - 99
MF international non-operator routing code Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. MF international (non-operator) routing code to be written back into the SETUP. This parameter is used only if the call is routed over MF signaling. Range: 120 - 199
MF international operator routing code Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. MF international (operator) routing code to be written back into the SETUP. This parameter is used only if the call is routed over MF signaling. Range: 120 - 199
Max channel usage Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. Maximum channel usage (as a percentage of the channel's total capacity) to be used in admission control, if this action is chosen. A media channel whose usage is higher than the maximum channel usage will be rejected by admission control. The default is 100 (indicating that the channel will be rejected only when it has no free capacity).
Congestion level 1 acceptance probability Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. Attribute that is added to the routing request after the media channel is selected and used internally. It specifies the probability, expressed as a percentage, of accepting a signaling channel congested at congestion level 1. Range : 0 - 100
Congestion level 2 acceptance probability Change This field is visible only if this attribute is selected in the Optional Attributes to set field. If this field is visible, it is mandatory. Attribute that is added to the routing request after the media channel is selected and used internally. It specifies the probability, expressed as a percentage, of accepting a signaling channel congested at congestion level 2. Range : 0 - 100
Alarm state Read only Specifies whether any alarms are currently raised for this object. Values:
  • Clear
    No alarms are currently raised.
  • Attention Required
    Attention Required - the object is not operating normally, and needs operator intervention. (This indicates that the total primary file size has crossed one of the thresholds (but is still above the minor alarm threshold).
  • Attend To Dependent
    Attention Required elsewhere - another object on which this object depends is not operating normally.
Alarm log correlator - Attend To Dependent Read only Identifier of the log message for the event that caused the last Attend To Dependent alarm state for this object. This field is reset when the Attend To Dependent alarm events field is reset to zero.

Alarm state changed timestamp Read only The time at which the Alarm state last changed.

Requested status Read only Specifies whether an administrator has attempted to enable the Trunk Routing Action. Values:
  • Enabled
    The object has been enabled.
  • Disabled
    The object has not been enabled or has been disabled.
