A short answer is "yes, after a software update".
A longer answer is that hardware supports dual-TRX operation, but
software support is not there yet. We might be able to fix software
before we ship beta units, but even if not - you will be able to get
the software update later.
Also keep in mind, that UmTRX should be able to run multi-ARFCN
OpenBTS and in this case it'll be able to handle much more calls. We
haven't tested this mode of operation extensively yet, but
theoretically we might be able to support 14ARFCNs (2x7ARFCN) which
equals to (14*8-1)=111 calls. At this scale you're most likely limited
by computing power of your PC rather then UmTRX hardware. Whether we
could get UmTRX in Multi-ARFCN mode through certification or not is
still a question, but it should be fine for lab testing.
