hi john,
AO TX I1A:0 RBS 2206
Fault Name: TX offending
Remark: Only CDU-F
Description: This fault arises when the BSC has configured two TXs on the same frequency or if the frequency separation is below the guard band (600 kHz in GSM 900 and 1 MHz in GSM 1800). The TX will be disabled in order to protect the CDU-F from overheating.
Possible reasons: BSC wants to move a frequency from one TX to another TX and “forgets” to disable the first TX before configuring the second TX. The TX will be automatically disabled and reconfigured to a non-offending frequency.
Action: The frequency planning is wrong (check Data Transcript for this cell).
