Function of PDM

PDM distributes the -48 V power to CMBs,

DTRUs and FCMs, and provides overload

protection via circuit breakers. In addition toa circuit breaker for each module, a main

switch circuit breaker is placed at the -48 V

input end on the top of the BTS cabinet.

Function of AEM

Combines the transmit signals of multiple carriers.

Provides bidirectional signal channels from the

BTS to the antenna for the transmitting band and

from the antenna to the BTS for the receiving band.

Gives an alarm when the VSWR of the antenna

port deteriorates.

Suppresses the interference out of the workingband and spurious emission.

Flexibly configures carriers.

Implements diversity receiving.

All the nodes are connected in closed loop, it can span larger distancesthen other types of networks. The reliability is higher; as it strays connectwith the BSC through the other end, if the link is broken from one place.

It can deployed in suburb and rural places
