Thanks Neels.
Where we can get more information on this? We would like to use this
loopback for BER measurements.
Is it suitable to do that?

One more query regarding loop-back call :
"bts <0-0> trx <0-0> ts <0-7> lchan <0-1> loopback",
we tried this command to start loop-back call once MS is registered to
the
network.
But we are not seeing any loop-back call happening in nitb and osmo-bts
logs.
This command only sets a loopback flag on a given lchan and does not
actually
initiate a call. IIUC after setting the loopback, the loopback should
happen
when you make a voice call using that time slot and lchan.
It might make more sense to start a call and set the loopback on the lchan
while the call is active. So this does not replace the other MS.
From the code it seems the loopback flag is not cleared before / after a
voice
call, so it looks like the given lchan will remain a loopback for any
number of
calls (that end up on that lchan).
I'm not 100% sure though, only skimmed the code briefly,
I've never used this before.
