17.45. NMLT - No multi-level precedence and preemption on trunk 
Feature:
Suppression of incoming and outgoing MLPP information.
Function:
If MLPP is released in FEASU, then MLPP information is carried via all system trunks,
provided that this is permitted by the signaling procedures used.
This transport can be blocked for certain trunks by setting NMLT.
NMLT (not set): Trunk carries MLPP information.
IMPORTANT:
NMLT - applies to outgoing and incoming traffic.
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
Protocol variants:
All protocols that transmit MLPP-related information
