17.44. NLRD - Partner system sends no LCR authorizations in
the Data service 
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.
