While we are still on this topic. I have succesfully implemented SFH on 1800 few months ago. Now it’s time that I do the same for 900, but we had a very big problem with CSSR. We have mixed EGSM and PGSM frequency on one MA list. Does anybody know if mixing these frequencies is a problem and if it is why? We are using Siemens PD DUAMCOs and FDUAMCOs.
