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 -- Dieter Spaar, Germany spaar at mirider.augusta.de
