You can use AMO TACSU, AMO TDCSU and AMO TSCSU to configure and edit the line circuits in an existing trunk group.

The line-specific parameters are grouped into various classes and are assigned with the AMO COP (Class of Parameter). The call processing parameters of the line circuits are assigned with the AMO COT (Class of Trunk).

The COS (class-of-service) is relevant for transit and satellite PABX traffic. Only the direct trunk access and tie-trunk classmarks are evaluated. If you want to prevent a trunk from being seized with a tie trunk, you must remove the direct trunk access classmark from the tie trunk's COS (AMO COSSU).

Use the AMO BUEND to define a trunk group. All line circuits in a trunk group must have identical properties. The AMO TACSU, AMO TDCSU and AMO TSCSU are used to assign line circuits to a trunk group. You can use the AMO BUEND's NO parameter to set the maximum number of line circuits/B channels to be configured. Changes to line circuit parameters are automatically saved by the AMO TACSU, AMO TDCSU and AMO TSCSU to the memories of all line circuits assigned to this trunk group.

Outgoing routes are defined with the AMO RICHT and THE LCR AMOs.

A trunk group may be assigned to several routes.

However, a line circuit or a B channel group may only be assigned to one trunk group.

AMO TACSU

The AMO TACSU handles all analog trunk circuits, tie-line circuits and satellite PABX tie trunks.

AMO TDCSU

The AMO TDCSU handles the digital circuits (S0, S1 or S2).

AMO TSCSU

The AMO TSCSU edits all line circuits for special configurations (APSE).
