GuestCAN ANY BODY TELL ME ABOUT BTS ALARM AND AND THIER CONNECTION
sairam
Guestrabindra sir,
i got an alarm at a site ,
BTS operation degraded:RX level differ bet. main & diversity.i thought its the VSWR problem but i got reading 1.21&1.19 at main & divercity end respectively,
i changed the trx and tightend the SMA connectors,i changed the combiners too still i m having the same alarm .
can any one help me out?Yogesh
Guesthi sairam,
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;

GuestThanks Patrick, the cause of continuous restarts was unstable voltage… 🙂

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.

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.)
