MERLIN LEGEND Communications System Release 5.0
Installation 555-650-140
Installing the Control Unit
Installing the Modules
NOTE:
DIP switches 1, 2, 6, and 7 determine whether the tie trunks are protected
or unprotected. DIP switches 3, 4, 5, 8, 9, and 10 determine the mode.
Simplex mode is always protected. Therefore the Protected/Unprotected
settings for DIP switches 1, 2, 6, and 7 have no effect.
The successful implementation of a tie trunk format is dependent upon
matching the characteristics of both PBX systems it connects. The
preferred signaling formats for a tie trunk originating in the system are
shown in
Table 2-5. Signaling Formats for the 400EM (Tie Trunk) Module
