Specifications
Relays in the COLU and RT under control of the PG-Plus Alarm Unit (PAU) or PG-Plus Management Unit
(PMU) provide a path for subscriber drop test and metallic fallback operation. These relays are used to establish
a path to channel 1 of the LS/GS RT during fault conditions and to provide for drop testing of the selected
subscriber line from the CO location.
