3.1 HDT300 STATION COMPONENTS
The main hardware components that make up the HDT300 base station include the following:
Transceiver Shelf
Fan Shelf
Channel Unit
Base Station Controller Unit
Power Supply Unit
Extended Interface Board
The transceiver shelf, part number HD-TM1E, houses the station modules, provides interconnection
points to additional transceiver shelves, and to the Extended Interface Board.
points to additional transceiver shelves, and to the Extended Interface Board.
The CHannel Unit (CHU) provides a 12.5 kHz RF channel with a 2-timeslot TDMA call capability. Each
transceiver shelf may be populated with up to four (4) CHUs.

The Power Supply Unit (PSU) provides conversion from 110/240 VAC to the DC voltages required to
power the station equipment. Each PSU provides DC power to both BSCU modules while PSU1 powers
CHU1 and CHU2 and PSU2 powers only CHU3 and CHU4.
