LAR activation
LAR is active when a call is rejected with a cause value in the range of #34–#47 and #3 (no route to
destination). The range of #34–#47 indicates congestion and that resources are unavailable. The
following cause values activate LAR:
NOTE:
When country code 13, protocol version a, is administered on the DS1 Circuit Pack
screen, only the cause values #10 and #89 activate LAR.
LAR terminates when:
•
call is successfully routed
•
call is rejected with a non-LAR-triggering cause value
•
no further route preference can be used to route the call
LAR measurement
You can measure the number of attempted and successful LAR reroutes. The Measurements LAR Route
Pattern screen displays LAR measurements for a particular route pattern.
Interactions
•
Automatic Circuit Assurance
LAR rerouting attempts are recorded as short holding time calls.
•
Distributed Communications Systems (DCS)
If a non-DCS trunk preference is selected for rerouting a DCS call, DCS feature transparency is
lost. If LAR for a DCS call is done within the same DCS trunk group, feature transparency is not
lost.
