I have been monitoring the effect of this alarm in some cells.
In one cell, CSSR and CDR was very bad but we couldn’t find any radio related issue. During drivetest it was found that some 2 of the 4 trx are transmitting with very bad rx_qual and low c/i, but with good rx_lev (similar to interference, but to problem freq was found). After changing both CU everything became normal. In this particular case, alarm 7743 was being shown for 4-12 hours.
In some other case this alarm causes no severe degradation in KPI.
