Case F
External alarms
Case F architecture does not provide any external alarms control.
Power supply:
Case-F Remote Unit is available in two versions: one feeded by universal mains (85 to 265 Vac),
the other by negative power supply (-72 to -36 Vdc): in fi gure 3.6.3, the 85/220 Vac connector
and the -72/-36 Vdc connector are described. Power feeder is always internal. The power
cable is always included in the Case-F Remote Unit kit.
RF ports:
• 1 RF antenna port, transmitting/receiving signals to/from distributed antennas. This RF
antenna port is a duplexed N-female connectors. The port can be connected to the
antenna either directly (ie. through RF jumper cables) or through splitters, thus allowing
more antennas to be fed.
• 1 RF auxiliary input and 1 RF auxiliary output (designed to receive and transmit additional
signals). Auxiliary input and output ports are SMA-female connectors.
Optical ports:
• 1 optical output port, transmitting UL signals to TFLN master optical TRX;
• 1 optical input port, receiving DL signals from TFLN master optical TRX.
Visual alarms:
Two control LEDs are provided on the Case-F upper side (fi g. 3.6.2).
The green LED describes the power supply status, while the red LED describes the major
Remote Unit failures (Table 3.6.1).
