The Combining Unit for DTRU BTS (DCOM) is specially
developed in compliance with the TRX combining requirement for the double-transceiver
BTS3012. It combines two paths of DTRU transmit signals into one path and
outputs the combined signal to the DDPU. It is typically applied when three to four TRXs need to be
combined, for example, in case of S5–S8 configuration. The frequency band of
the combiner includes the downlink frequency band (921 MHz to 960 MHz) of the RGSM.
The DCOM consists of a 3-dB electrical bridge, a 2-in-1
combiner with large power, and an in-place detection DB26 interface circuit.
The 3-dB electrical bridge combines two paths of input
signals into one path. The DCOM is optional. There are up to three DCOMs under
full configuration. The DCOM configuration principle is to use the 2-in-1
function of the TRX preferentially, and configure one or more DCOMs if
necessary.
The in-place detection mechanism for the boards in the DAFU
subrack is as follows:
The boards in the DAFU subrack are divided into
two groups: DAFU0–DAFU2 and DAFU3–DAFU5. The template of the active DAFU is
used to check the DCOM in the same group. If you configure a DDPU in slot 2 and
a DCOM in slot 3, and leave slots 4 and 5 empty, the in-place detection of the
DCOM in slot 3 will fail.
