ECM Interface Topology and Connectors
The ECM PWR- GRI PCBA provides the interface between cabinet sensors,
APU control, and power conditioning to the ECM. The interface also supplies all
the necessary signals, alarms, logic power, and analog voltages required for
telemetry to the cable head end, central office, or network manager, and allows
the Alpha Systems control module to start and stop the Engine alternator as
part of network controlled periodic tests and exercises.
