Each BTS gets its own E1 line data structure. They are meant to bind
each to their own (virtual?) mISDN device.
BTS0 uses TS01 (siganlling) and TS02/03 (TRX0), TS04/05(TRX1)
BTS1 uses TS11 (siganlling) and TS12/13 (TRX0), TS14/15(TRX1)
BTS2 uses TS21 (siganlling) and TS22/23 (TRX0), TS24/25(TRX1)
* remove old HAVE_TRX1 definition, replace it with '-1' commandline argument
* make sure we actually configure the OML TRX attributes with a different
ARFCN than TRX0
* make sure we configure timeslot 0 of TRX1 also in TCH/F mode
This code is untested, but if you have a dual-trx BS-11, and the second TRX
is activated, you should be able to run bsc_hack with the -1 option to enable
and use the second trx. It works like this:
* TRX1 shares E1 timeslot 0 for signalling
* TRX1 RSL link uses TEI2 (TRX0 uses 1)
* TRX1 on ARFCN+2, i.e. if you have TRX0 on 122, TRX1 will be 124
