Ckib/Csib Wiring - Vodavi Starplus Triad-S Installation Manual

CKIB/CSIB Installation
Each CKIB or CSIB has 3 loop start CO line interfaces. The loop start
CO/PBX lines are connected to RJ-11 connectors on the right side of each
board.

CKIB/CSIB Wiring

There is one 50-pin female amphenol connector on the left side of the
board. This enables the system to be cabled to the main distribution
frame (MDF). A 25-pair telephone cable must be prepared with mating
connectors to extend the interface circuits to the MDF. The cables should
be routed through the cable clamps at the bottom of the KSU to the MDF.
These cables are terminated on industry standard 66MI-50 type punch
down blocks. It is recommended that 66MI-50 split blocks with bridging
clips be used to simplify troubleshooting and to quickly isolate any faults.
