Amber & Sarosh,
According to the GSM Standard, only TRX0 has to transmit constantly.
Secondary TRX's can transmit only when there is actual data to
transmit.
So if you want to see transmission on the TRX1 you should either:
1. have more than 6 active call legs (more than 3 acive calls), or
2. make TRX0 SDCCH only and leave TCH only on the TRX1 and make a call.
In either case you'll see that the transmission on TRX1 is not
continuous, unless you have all TCH's on TRX1 busy.

Hi
We have configured OsmoNITB, OsmoBTS and OsmoTRX to run two transceivers
using UmTRX. But somehow when the spectrum is monitored, the only frequency
that is detected is the one TRX0 is tuned to. ARFCN set for TRX1 is not
detected i.e. TRX1 does not seem to be transmitting on the specified
frequency.
Can anyone please tell what possibly could be the issue?
Thanks & Regards,
