"multi-TRX" in this context simply means that you can stack multiple unit
to behave like one BTS with multiple TRX rather than multiple BTS with one
TRX each.

We don't have explicit support for it in OpenBSC so far, but I think there
should be nothing major missing either, as we already support multiple TRX
in the E1 case.  All we have is suddenly two TCP connections with RSL rather
than one.

It probably boils down to somebody testing it and tracing any remaining bug,
but there's no fundamental part of the code that needs massive changes to
support this.

I'm in the process of building one of those custom modified RJ69 cables that
you need to stack them.  I'm busy with lots of other work, and it is not of
very high importance, though.

Regards,
	Harald
