MML command: DSP RFDESPARAM / DSP DESENS

MML command: LST RXATTEN

Check the TMA gain(if TMA used)

MM command: LST TMAGAIN

whether nearby sites also have the same high RTWP feature

Describe the RTWP feature (like it is always high or some times high ). What is the RTWP range

MML command: STR RTWPRTTST (NodeB LMT)real time RTWP monitor (both primary and secondary RTWP)

compare the traffic load with the RTWP. Check whether high traffic or interferece cause the high RTWP.

MML command: SET TXSWswitch off the downlink tansmit power and monitor whether interference disapper or not

Whether 3G system shared antenna with 2G or not? Whether TMA used or not? Whether repeater is located nearby?

whether primary and secondary RTWP are both have high

swap the primary feeder with the secondary feeder to check whether high RTWP swap or not.

differentiate internal or external interference

Disconnect the jumper from the cabinet and then monitor the RTWP.
