All connections to the DS 616 system are made by the way of a main distribution frame
(MDF) except for the 120 VAC power and backup battery. All cabling to and from the
MDF should be made using ACA approved 0.4mm or 0.5mm twisted pair cable.

an amphenol type connector on one end and a 25 pair 66m/50 block on the other. The
amphenol connector inserts into socket P4 on the KSU motherboard.
The first 20 pins of the amphenol connector are assigned to connections of trunk
interfaces on a trunk interface card. The next 6 pins are for connections of
miscellaneous circuits and the last 24 pins are assigned to connections of 12 DLI ports
on the mother board.

RJ45 connector plugs into socket P5 on the KSU.
Connection for the SLTs is via a 4-pair modular jack (RJ-45) on the motherboard.
