4.2 Installing RF Cables
The RF cables to be installed on site include:
GPS/GLONASS clock RF cables
RF cables between CDDU/CHPA/CTRM (single-channel)
RF cables between CDDU/CMPA/CMTR (multi-channel)
RF cables include the GPS/GLONASS clock RF cables, RF
cables connected to the CDDU, and jumpers for multi-channel
configuration.
Grounding cables include PGND cables of the cabinet and GND
cables for cabling racks. Grounding cables for cabling racks
include GND cables for indoor cabling racks and for outdoor
cabling racks.
The –48 V DC power is led to the terminal block on top of
BTS3606 through the power cable to supply power for the whole
BTS.
Optical fibers connect the CCPM/CECM of the BTS baseband
subrack and the MTRM of the soft site.
Optical fibers of combined cabinets transmit signals between the
basic cabinet and extension cabinet.
A transmission cable is made up of E1/T1 trunks (Generally, a
transmission cable contains four E1/T1 trunks). It provides trunk
connection from BTS to the BSC or other BTSs.
Cables connecting the EAC and the BTS3606 cabinet include a
data cable and a shared grounding cable.
The EAC report environment alarm information collected to the
BTS through the data cable. The EAC shares the same ground
with the BTS through the shared grounding cable.
RF cables and optical fibers connect the basic cabinet and
extension cabinet when BTS3606 cabinets are combined to
realize communication between them.
