4.5 DCOMThe Combining Unit for DTRU BTS (DCOM) is placed in the DAFU subrack. It can be inserted
in the DAFU subrack with the DDPU. The DCOM is optional and up to three DCOMs can be
configured. The precondition for configuring the DCOM is that the wideband combination
function in the DTRU must be used when there is an additional requirements for the combination
of signals.
4.5.1 Functions of the DCOM
This describes the functions of the DCOM. The DCOM combines two routes of TX signals fromthe DTRU, and then sends them to the DDPU.
4.5.2 Working Environment of the DCOM
This describes the working environment of the DCOM. The DCOM receives two routes of DL
signals from the DTRU and combines them into one route. Then, the DCOM transmits the
combined signals to the DDPU, which sends the signals to the antenna for transmission.
4.5.3 Working Principles of the DCOM
This describes working principles of the DCOM. The DCOM consists of a 3 dB electrical bridge
and a high-power load.
4.5.4 Ports on the DCOM
This describes the ports on the DCOM panel. There are four ports on the DCOM: ONSHELL,TX-COM, TX1, and TX2.
