Setting Cable Loss Values
Cable loss values for the TX and RX test cable configurations are
normally set by accomplishing automatic cable calibration with use of
the applicable test equipment. The resulting values are stored in the cable
loss files. The cable loss values can also be set/changed manually.
Cable loss values must be manually entered in the LMF
database if manual cable calibration was performed.
Failure to do this will result in inaccurate BTS calibration
and reduced site performance.
