FAILURE IN CONNECTION TO FREQUENCY HOPPING DATA TRANSFER FAILURE IN FREQUENCY HOPPING DETECTED BY TRX
The DSP is unable to send data to the F-bus. The DSP has received corrupted data from the F-bus. During the supervision period, the TCH time slot has suffered excessive interference in idle mode that is equal to or higher than the operator-defined alarm threshold percentage. The TX power level has decreased from the given value because of an HW-fault in the RFU. This alarm indicates that the SWR level in the TRX TX interface is too high. It is caused by the cabling or the combiner fault. A major fault (or faults) has occurred in the base station. Check the fault reason from the supplementary text field of the alarm. Major fault (or faults) has occurred in a unit (or units) that belong to the sector indicated in the alarm. Critical fault has occurred in a TRX. Critical fault has occurred in a TRX
Calls have been cleared repeatedly on the same A interface circuit due to BTS and transcoder unsynchronisation and the number of successive releases has exceeded the limit defined in the PAFILE alarm parameter

The Abis frequency is too high or too low, or it fluctuates so much that the master clock tune is unreliable and tends to oscillate too much. Another reason for this alarm can be that the oven adjustment OSCILLATOR ADJUSTING TEMPORARILY scenario has tuned the oven too near the edge. INTERRUPTED When the tune is stopped, the master clock can go by itself out of specification and therefore calls may drop after several hours or days. LAPD FAILURE The alarm concerns the LAPD link of the TRX. A failure has occurred in sending the system information to the BTS site after the recovery measures or configuration changes of the BSS radio network. The TRX in question or the whole cell may be unable to transmit traffic. The same radio network alarm has changed its alarm state (start/cancel)20 times consecutively, always during informing or cancelling delay,and has thus been filtered by the alarm system.
Mean holding time on a channel is below the operator-defined minimum during the measurement period. The alarm is used to supervise the functioning of traffic channels and to detect the possible faulty channels. The rate of calls terminating in failure on a channel is above the threshold value set by the operator. The alarm is used to supervise the functioning of traffic and signaling channels, and to detect the possible faulty channels. The BCF controls the frequency of the 13 MHz oven oscillator within a certain range. Difference of Rx signal strength between main and diversity antennas is higher than the limit value (default 10 dB). 01 no successful SDCCH seizures 02 no successful TCH seizures 03 no successful SDCCH nor TCH seizures 10 no successful GPRS transactions 11 no successful SDCCH seizures and no successful GPRS transactions 12 no successful TCH seizures and no successful GPRS transactions 13 no successful SDCCH nor TCH seizures nor GPRS transactions
