6) Connect the fiber between MTRM and MBPM (The silkscreen "UP_FIBER" i s
made on the fiber interface at the bottom of MTRM). If fiber cascading is necessary,
connect the fiber cascading connector to the cascading fiber interface of the
MTRM (The silkscreen "DOWN_FIBER" is made on the bottom of the cascading
fiber interface);
7) When E1 cable is used for transmission, connect the E1 trunk cable to the E1
interface of MBPM; when fiber is usded for transmission, connect the pigtail of the
fiber to the fiber interface of MBPM;
8) Connect GPS cablesd under MBPM and take waterproof measures for the
connector via three types of tapes;
9) Connect power cables to MAPM;
10) Connect grounding cables between the cabinet and the PGND bar.
Caution:
If fibers are used for transmission, the optical transmission fiber connector at the bottom of the MBPM
should be connected. That is, connect one end of the connector to MBPM and extend four pigtails (marked
as WTX, WRX, ETX, and ERX respectively) from the other end. Connect the pigtails "WTX" and "WRX" to
the upper-level BTS or BSC, and pigtails "ETX" and "ERX" to the lower-level BTS. Note the marks on the
fibers and connect them correctly.
III. Procedures to distribute the waterproof fibers at the bottom of MTRM
During the distribution, be careful not to break the core wire of the fiber connector.
