■ PIGGY-BACKING TO PBX
SBS can be connected to the extension circuits of another PBX. In this case the PBX must
be approved as a host PBX system.
The connection of PBX extension to SBS is made in the same way as PSTN connection and
terminated at exchange line ports on the CCU.
NOTE : In this manual “T” and “R” on the PCB have been replaced with “A” and “B”, respectively, in the description.
