SHELTER BTSSHELTER BTS


SHELTER BTS SPECIFICATIONSSHELTER BTS SPECIFICATIONS

• The ZXG10 SBTS normally holds the ZXG10-BTS(V2) rack and matched device, so the ZXG10 SBTS supports all the features of the ZXG10-BTS(V2).

• It can hold 1, 2 or 3 ZXG10-BTS(V2) racks respectively. The largest capacity is 36 TRXs. The shelter of the ZXG10 SBTS can also contain the ZXG10-BSC and the ZXG10-BTS(V2) simultaneously.

• Standard configuration consists of two accumulator sets with a total capacity of 400 AH (Max. 800AH). This configuration ensures a power supply of 4~8 hours.


SHELTER BTS SPECIFICATIONSSHELTER BTS SPECIFICATIONS

•The ZXG10 SBTS provides integrated power and environment monitoring system and the monitor of the base station system involves no additional transmission resource.

• The Shelter may be applied in transmission of Microwave, SDH, PDH, and other modes of transmission.

• Two conditioners mounting on the wall work in timed shifts. This secures an operation temperature of 25 C 5C.
