17.42. NLCR - Partner system sends no LCR authorizations in
Voice or Fax service 
Feature:
LCR Least Cost Routing
For example, performing switching with E.164 numbering plan in network
Function:
If the COT of a trunk of parameter NLCR 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 NLCR parameter
is activated or deactivated.
NLCR refers to the LCR class of service assigned to a trunk when generated with the
parameter "LCOSV ... LCR class of service for voice, fax".
IMPORTANT:
At present, CORNV33 and CorNet-NQ are the only protocols that transfer
LCR authorizations.
