reported over the IP back haul. Fault and alarm information may be accessed using the

FlexWave OMC-R management solution.

1.2.4 IP Backhaul Connection

The IP back haul cable connection is through an Ethernet port that consists of a single bot-

tom-mounted hardened RJ-45 female connector. The IP back haul cable carries the voice and

data traffic plus all OMC-R provisioning, alarm, and performance monitoring communications

between the microBTS and the BSC. The IP back haul connection also provides DC power

(POE) to the IP back haul device with a 15 watt maximum power output at 48 VDC. The

maximum drop cable length is 300 feet (91.4 m).

1.2.5 Network Listen Antenna Connection

The Network Listen antenna connection is through a single top-mounted NMO (female) RF

connector. The Network Listen antenna attaches directly to the NMO connector.

1.2.6 Base Station Antenna Cable Connection

The base station antenna cable connection is through one 50 Ohm N-type female connector.

The microBTS includes an internal duplexer which allows a single antenna cable to carry both

forward and reverse path RF signals between the base station antenna and the microBTS.

An externally-mounted lightning protector is available as an accessory. The surge/antenna

connector on the lightning protector is an N-type female connector. The microBTS enclosure

must be properly grounded for the lighting protector to function properly.

1.2.7 Powering

The microBTS is powered by 90 to 265 VAC (nominal 120 or 240 VAC), 47 to 63 Hz power

or as an option -48 VDC. The AC or DC power is supplied through a 20-foot three-wire power

cable that is provided with the enclosure. The power cable connects to a mini 3-pin AC or DC

power connector mounted on the bottom of the microBTS enclosure. The power cable is rated

for indoor or outdoor use and must not be placed within electrical conduit as this will impede

the cooling of the cable during usage. Power cables in lengths of 40, 60, or 100 feet are avail-

able separately.

The stub end of the power cable must be routed to an external junction box (not provided) for

connection to the AC power source. A circuit breaker rated at 15 amps (120 VAC) or 5 amps

for 48 VDC applications should be used to provide overcurrent protection for the microBTS

power circuit. It is also recommended that an external AC outlet (not provided) be installed

near the microBTS enclosure to power test equipment and power tools.

1.2.8 Grounding

A grounding terminal (hex socket capscrew and washer) is provided on the bottom of the

enclosure for connecting a grounding cable to the enclosure. A 1.5 meter #6 stranded copper
