The communications power supply (BS+ and BS-) is connected to the com-
munications power supply connector on the Master Unit. Doing so will supply
communications power to the Slave Units on the trunk line from the Round
Cable II, Flat Cable I, or Flat Cable II.
(1) Connect the communications power supply at only one location for the
trunk line and each sub-trunk line.
(2) Connect the communications power supply to the downstream port com-
munications power supply connector on the Repeater Unit to supply pow-
er to a sub-trunk line.
