Hello Rex,
Do not forget that this Parameter (TX_Integer) is working with S parameter that depend on the type of your CCCH Combine type; if you have CCCH combined or not,
any way try and inform us with the result,

Regards

Probably not... but you can try :)

Rex - 21st August 2009  (10:06 GMT)

Anyone?

Rex - 19th August 2009  (18:54 GMT)

Hi,
the default parameter in our network of param TX_INTEGER is 50. In cells located in mountains with high SDCCH Assignment Failures, if we reduce the value of TX_INTEGER to 32, will that decrease SDCCH Assignment failures?
Regards,
Rex
