PNR alternative Routing
1037:
PNR route choices at incoming proprietary calls
This command states the number of PNR route
choices which are allowed to be accessed by incoming
proprietary calls to a PNR number. PNR alternative
routing is performed, if the called destination cannot be
reached via the first PNR route choice.
If no more alternative route choices are available or
allowed, the call is released due to ‘congestion’ and
the preceding proprietary PBX may perform alternative
routing.
Valid data: 0: 1 route choice
1: 2 route choices
2: 3 route choices
3: 4 route choices
Default data: 3: 4 route choices
Basic call service - Travelling Class Mark
0171
Travelling Class Mark (TCM)
This command is used to control and restrict
extension/operator calls to private network routes.
Each extension is assigned a TCM value.
In addition, each route choice defined for a given
destination in the network is also assigned a TCM
value. By comparing the TCM levels for call originator
and chosen route, it is decided whether call setup may
continue or shall be rejected (see commands 91x4).
To allow a call setup, the TCM value of the call
originator must be higher than or equal to the chosen
route.
Valid data: 0 (highest restriction level) - 7
Default data: 7 (lowest restriction level)

Travelling Class Mark (TCM)
This command states the TCM for the incoming trunk.
If no “Travelling Class Mark” is received from the
preceding node the defined TCM value is used to
decide whether or not a call is allowed to continue as a
transit network call.
If the defined TCM value is lower than any of the TCM
Valid data assigned to the network routes (see
commands 91x4), the call setup to the network is not
allowed.
Valid data: 0 - 7
Default data: 7
