17.36. MLPR - Multi-level precedence and preemption 
Feature:
Trunk can be used for MLPP.
Function:
The trunk may be disconnected by MLPP in line with protocol if it is seized by MLPP
routine
or a higher routine and is required for an even higher level. It is not disconnected
if the
trunk is seized by a non-MLPP call.
MLPR (not set): Trunk may not be disconnected by MLPP Calls.
IMPORTANT:
MLPR - For outgoing traffic only.
AMO Interrelationships:
The parameters MLPR and NMLT can be set independently of each other and independently
of
the MLPP release in FEASU.
MLPR and NMLT only work if the MLPP feature is released in FEASU.
If MLPR is set for the trunk, then NATL or NATR may not be set at the same time.
The introduction of MLPR and NMLT means that the PAR CCAL can be omitted.
Device types:
Trunks with Voice service
