nanoBTS Multi-TRX configuration?

Hi! Does anyone on this list have experience with nanoBTS Multi-TRX configurations? I've built a TIB cable (10pin RJ69 to 10pin, 1:1 wiring, i.e. pin1 is pin1 on the other plug, pin2 is pin 2, etc.) and connected the two BTS. When I power them up simultaneously, they still come up as two individual BTS with each their own unit ID. I've tried to set the unit ID to something like 1801/0/0 on the first one, and 1801/1/0 on the second. However, any non-zero TRX ID of the unit ID is rejected by the BTS. Any hint how I can make them behave like one BTS with two TRX is appreciated. I'm expecting only one OML Link but of course two RSL links (one for each TRX).
