17.44. NLRD - Partner system sends no LCR authorizations in the Data service Previous topic Parent topic Child topic Next topic

Feature:

LCR Least Cost Routing

Function:

If the COT of a trunk of parameter NLRD is set, then the LCR authorizations sent by the partner system are replaced by the LCR authorizations generated on the trunk.
If the parameter is not set, then the LCR authorizations are applied from the transferred protocol.
If a protocol does not transfer any LCR authorizations, then the LCR authorizations of the trunk are always applied, irrespective of whether the NLRD parameter is activated or deactivated.
NLCD refers to the LCR class of service assigned to a trunk when generated with the parameter "LCOSD ... LCR class of service for data".
IMPORTANT:
At present, CORNV33 and CorNet-NQ are the only protocols that transfer LCR authorizations.
