5.2.2 Loop-start Lines for 216 Base KSU (Figure 5-2)
The DCS-816 system requires MDF connection for analogue trunk (loop-start) lines. Ten (10)
analogue trunk lines can be connected to the system if an 8TRK card is installed in the expansion
slot. All connections for loop-start lines can be done through the champ connector on the base
board. See Figure 2-3 and refer to section 2.5 (MDF Cabling).
Use one pair twisted wires and connect each loop-start C.O. line to the trunk port you choose via
the champ connector on the base board.
