can any one help me out?18th January 2007 at 11:39 #42560YogeshGuest
pls check these: 1.parameter RDIV should be ON.
2.it might be possible only RX Cable swap from other sector.
3.check all cable inside the BTS one point to other, it may be swap.
Reason:this alarm can come when diversity may go beyond 5 So any of the cable inside BTS Gt. swapped.

“What might be the reason of 7715 CONTINUOUS RESTARTS OF BCF”
Because your BTS reset 3 or 4 times in less than 5 minutes.
I don’t remember exactly but too reset in little times.
It is not a critical alarm. You can reset by ZEOR:bcf:n°alarm;26th January 2007 at 15:52 #42564AzamatGuest
Thanks Patrick, the cause of continuous restarts was unstable voltage… 🙂27th January 2007 at 10:54 #42565JadeeGuest

There is disturbance in the serial DL bus or bus is broken.

Patrick – Feb 1,2007
Thank you so much for the suggestion.
I got another question.
Is the RRI of Metrosite, compatible to Ultrasite? Can u use that module directly to Ultrasite? By re-mapping it at Traffic Manager?
Many thanks.8th February 2007 at 16:23 #42572patrickGuest
Jadee – 8 Feb 2007
We don’t have RRI for ultrasite. We have FXC ET1/T1.
4 PCM in/out
On traffic manager
– Select unit (FXC or RRI)
– select interface (PCM 1 …4)
– place Tch, TRXsig, OMUsig, Edap, on your abis allocation for BTS.
(Warning: Metrosite don’t work with hubmanager.)
