Chapter 3: Electrical Operation

3.1 Power 

The BCS 4R equipment is passive with the exception of the repeater and Vector OTM card 
modules. The DSX chassis accept -48V office battery power to light the tracer lamps (TL) LED on 
the front of DSX and repeater cards and LEDs on the rear of the chassis. 

Power connects to the Power/Alarm Terminal Strip on the back of each DSX chassis. The strip 
terminates a bus on the chassis backplane; all DSX card connectors on the backplane tap into 
the signal lines of this bus. Power for the rear TLs passes from the bus on the backplane, through 
the DSX card, to a small PCB also on the backplane.
