Trunk Conditioning Write security: 3; Read security: 5

Sets known values in the signaling bits and the data field for outgoing DS0s which are cross-connected to a T1 port experiencing alarms. The trunk conditioning process consists of a 2.5-second transmission (indicating call termination), followed by a continuous transmission signaling the final condition as chosen by the user.

Trunk conditioning only applies to RBS T1s in the dedicated map.

Fault Signaling Defines to ATLAS the type of signaling being used on the trunk: E&M, LS/ GS Network or User, SW56, or Custom.

Fault signaling is only visible when RBS is turned on.

Fault State Defines the final fault signaling state:

Idle Used for one-way trunks; that is, for outgoing or incoming calls only—not both.

Seized Used for two-way trunks. Prevents the PBX from attempting to use a failed trunk for an outgoing call.

Custom Permits users to define the fault signaling to use in the form of A/B set to 1/0.
