Commissioning Procedure
This describes the commissioning procedure of the BTS. According to the transmission situation between the BSC and BTS, the commissioning procedure of the BTS can be classified into two types: commissioning procedure in transmission available scenario and commissioning procedure in transmission unavailable scenario.
Context l l
To solve common problems that occur during the commissioning, see
In this document, RFUs are classified into two types: DRFUs and GRFUs.
Procedure l Commissioning procedure in transmission available scenario
In the transmission available scenario, the transmission cables between the BSC and the
BTS are properly connected before the commissioning. Generally, the commissioning is performed on the BSC6000 LMT. If the commissioning can not be performed on the LMT independently, contact engineers on the BTS side to perform the commissioning task.
