The 'multi-carrier' approach multiplexes

must match accordingly. The '-m' option enables this configuration.
Could you give an example of necessary openbsc and osmo-bts
configuration for both cases?
Config files and README are attached. Note that the osmo-trx
multi-carrier '-m' option requires UHD master. I'm still backporting
the needed settings.
Also note that
the above configurations cannot be combined.
So I should not run "./Transceiver52M/osmo-trx -c 2 -g -m"?
Only "./Transceiver52M/osmo-trx -c 2 -g" or "./Transceiver52M/osmo-trx
-g -m"?
Or you referring to the incompatibility of configuration of openbsc? Or
Osmobts?
You cannot support, for example, 6 ARFCN operation on B210 using 3 TRX
on side A and another 3 TRX on side B.
Whether you use '-c 2 -m' or just '-c 2' depends on whether you want
to feed two ARFCN channels through 1 or 2 PA's respectively.
