Is it possible to use Three phones to support more than 2 timeslots?Do you use another branch? I cannot find tjhat info anywhere in the network-from-scratch page, two phones ,however work ok. And in the help output from transceiver app I find only the -2 option explicitly mentioned.
However a third socket, osmocom_l2.3 is established after connecting third phone and launching the trx-firmware, but transceiver says:
invalid option -- '3'.

I tried all suggestions and I still have a question "how to connect 3 phone
to transceiver ?"
1. phone - # osmocon -p /dev/ttyUSB0 -m c123xor -c path_to/trx.highram.bin
-r 99 
2. phone - # osmocon -p /dev/ttyUSB1 -s /tmp/osmocom_l2.2 -m c123xor -c
path_to/trx.highram.bin -r 99
3. phone - # osmocon -p /dev/ttyUSB2 -s /tmp/osmocom_l2.3 -m c123xor -c
path_to/trx.highram.bin -r 99

and transceiver -e 5 -r 99 -3

what I need to change in osmocom-bb2/src/host/layer23/src/transceiver/, 
to get it working???

thank you all !!!
