Hello everybody….!
please, can somebody helpme with the meaning of this alarm in Nokia BSC
1. 7743 MEAN HOLDING TIME BELOW DEFINED THRESHOLD
00 00 00 00 01 01 00 00 05 02 4dThanks a lot….!
of course… please I need something more than the NED answer…..!
thss alarm tells you that average time of busy RF timeslot is below treshold, last value in alarm shows the average time, so 4 sec. in your example, so this 7743 alarm is just a notice for you that probably something wrong with this cell because call duration is too short, may be they are dropped because of interference or transmission problem, in many times alarms 7745 occures together with 7743…

http://www.dx200.bizIf the alarm come back all the time, every days, then there is a really problem.
If you have 7743+ 7745 => check your TRX, câble, copler or antenna.
If it not hardware => Check Bcch, you have probaly same or adjacent frequence in area.
good luck.
i was told by one of the nokia trainers that if u have halfrate enabled in the cells then the chances of getting this alarm is high, thats because during the peak hours the halfrate transcoders could be completly full and hence that half rate call can be dropped due to transcoder pool cong. So u need to work on the half rate transcoder pool and check if there is any congestion.This could be one of the reasons apart from what has been mentioned already.

PLEASE HELP ME TO CLOSE THE TRE IN NOKIA SYSTEM
ALAWAYS I AM FACING THE LOOP PROBLEM & UNWANTED TRE AT BCSF NUMBER.
PLEASE HELPI 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.Please advice how to rectiy 7743 alarm from nokia bsc…
