[Openbts-discuss] OpenBTS Osmo-TRX high noise value

[Mona L. <mon...@gm...>]

Hi all,

I am a student currently studying OpenBTS. I have an Ettus USRP E110.
I have installed OpenBTS 5.0 according to the steps listed on the OpenBTS
wiki:

http://openbts.org/w/index.php?title=E3x0#USRP_E310_and_E100.2FE110
and
http://openbts.org/w/index.php?title=BuildInstallRun#Building.2C_Installing_and_Running_OpenBTS

I have successfully attached 2 MS to the BTS and placed a call to the 600
extension on asterisk and also between them. The problem is that there is
no sound between the 2 MS.


The output of the noise command is strange and I think it has something to
do with it:

OpenBTS> noise
noise RSSI is -2147483647 dB wrt full scale
MS RSSI target is -50 dB wrt full scale
INFO: the current noise level is acceptable

OpenBTS> power
current downlink power -10 dB wrt full scale


Also, OsmoTRX starts with the following message which is repeated
periodically. Is this normal or something to worry about?

NOTICE 111716960 10:39:28:3 Transceiver.cpp:404:pushRadioVector: dumping
STALE burst in TRX -> USRP interface.

Can anyone help me? If you need additional info, I will provide it.
