I don't know if that's valid by the spec or not, but it's part of a
pretty standard configuration in IMSI-catchers: CCCH+SDCCH4 +
6*SDCCH8 + TCH/F. That maximizes location updating capacity and
leaves one TCH/F for other ... mischief. Most of those IMSI-catchers
are based on commercial mini/nano-BTS equipment.
Thanks for this input. I think this a limitation of the BS11 only,
I have read that there are some limitations related to the SDCCH/8
of the BS11:
- only one SDCCH/8 per TRX
- not allowed together with SDCCH/4 on BCCH-TRX
Maybe the BS11 does not have enough processing power to handle it ? Of
course it could be that the documentation is wrong and it would work, I
have not yet tried it.
Best regards,
Dieter
