Nokia BTS O&M Link down

majid - 6th February 2019  (23:27 GMT)

my issue: o&m be done down after few minute O&m is up, but my bts is remain in hault state and we do not have covrage, i reset FSMFA and FXDB but i do not have covrage after link is up, we must send engineer on site to visit site and set warm reset.

Hi Atesz,
For Nokia , if O & M is BL and all thr TRXs are WP state then use ZDTI:NAME=BC040 ( 040 is the last 3 digit of the BCF. If it is BL-USR then use the below command to unlock it -> ZDTC:BC040:WO ;

Thanks
Shahria

sometimes it shows BL-SY but in this case you can retest the o&m, through this command ZEFR:12:L/U;
Also you can resett the ET throught this command, ZEFS:ET,256:BL/NU/TE/BL/WO;

keep try it.

It is not possible:

When you have

7706 BTS O&M link failure, your BTS is out

But alarm 7704 PCM Failure can stay in memorie. ZEEI => all is working but you have 7704. I think, it is a bug.

if LINK CHANNEL STATE is BL ZEEI, you BTS is failure with alarm 7706

Hello Guys,

Very often i meet the following problem: O&M Link of the BTS is goes down to BL, but the site is working and carry the traffic.

Is there any other chance to bring back the O&M Link without site visit and local BCFA reset ?

Thanks a lot,

Atesz
