Programming Procedures
Type of Trunk
Use this procedure to specify the type of trunk—loop-start (LS) or ground-start
(GS) — for each outside trunk connected to one of these modules:
400 GS/LS
408 GS/LS
800 GS/LS
408 GS/LS-MLX
Any combination of trunk types (all loopstart, all groundstart, or some of each) is
permissible.
This procedure is not used for a system registered with a KF registration number
(Key or Behind Switch). Ground-start trunks are allowed only for systems with
an MF (Hybrid) or PF (PBX) registration number.
