54 High BTS signal 0x0030 Error BIU
Description
The received RF signal from the BTS is above the alarm threshold. The alarm
threshold can be set at commissioning time.
NOC Actions
Check with engineers and adjust by remote to proper levels in BIU card. If input
is too high for the card to handle, dispatch field tech to insert attenuator
between BTS and BIU card.
Field Actions
Readjust or attenuate the BTS signal properly. Readjust the DL and UL for the
sector when done with the attenuation.
