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.
Fault Signaling Defines to ATLAS the type of signaling being used on the trunk: E&M, LS/
GS Network or User, SW56, or Custom.
Trunk conditioning only applies to RBS T1s in the dedicated map.
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.
