13 Installing the Integrated Micro-BTS
13.1 Introduction to the Solution of Micro-BTS Integration
13.1.1 Implementation of the Micro-BTS Integration
The micro-BTS integration solution integrates the transmission, power and micro-BTS
technologies and devices to provide users with an integrated networking solution. The
core of the CDMA micro-BTS integration of ZTE Corporation lies in the built-in SDH.
Through improvement on the structure and cabling process of the micro-BTS and
change of related boards, the SDH board is built into the micro-BTS. In addition, the
integrated UPS is added to the micro-BTS to provide the micro-BTS with the
interfacing and monitoring functions over the backup power supply (UPS power supply
and combinational power supply) and other devices. Meanwhile, the functions of
secondary power-off and dry contact monitoring are added to address new
requirements. The built-in SDH and integrated UPS are optional for micro-BTS
configuration. The following modifications to the micro-BTS are required if this
function is to be added to the micro-BTS:

Summary
BDM modification: Add the half-duplex RS485 monitoring interface and three
dry contacts (input), no longer support the RS232 monitoring interface;
RFM modification: Add six dry contacts (input), not to support the RS485 and
RS232 monitoring interface;
SDH selection: For the consistency of internal cabling, the CC4 connector is to
be used for the T1 interface on the built-in SDH board, corresponding to the
