13.1.2 Micro-BTS Integration Solution

Thanks to above improvements on the micro-BTS, the integration solution now poses
as an even simpler one with more flexible configuration available. With the solution of
the micro-BTS integrated with the backup power supply and transmission, the user's
requirements are taken as the first priority. There comes two basic integration solutions
for selection:
1.
indoor T150 board for the transmission of this part. The indoor and outdoor
T150 boards are the same except for the interface connector, that is to say, they
are basically the same in terms of performance and reliability. Support of power
supply: 24V and –48V input;
Improvement on cabling process: Consistent internal T1 cabling, that is, the
same cabling can be inserted either to the BDM or the to built-in SDH to make
upgrade and networking configuration more more convenient and flexible;
internal cabling for the monitoring part;
Improvement on pinboard (bottom plate): Add a standalone built-in SDH power
connector interface. The type of pinboard is settled on the 10W and 20W
micro-BTS pinboard, 40W micro-BTS main cabient pinboard and 450M
micro-BTS pinboard;
Add the lightning protection (class II) function for the monitoring part inside
the cabinet with some lightning protection design on the board; furthermore,
install an additional RS485/dry contact lightning protection board at the
monitoring interface of the cabinet;
Modification of T1 lightning arrester: Because of the changed T1 cabling inside
the cabinet, a longer coaxial cable may be needed for the T1 lightning arrester;
in addition, codes of the T1 lightning arrester needs changing;
Improve the door panel structure of the micro-BTS, to build the SDH into the
door panel of the micro-BTS.
