Hi,
We recently experienced in our network that expanding a cell to 8 trx’s by combining a FDUAMCO+COMACO in 8:2 config leads, if the any FCU is connected to that COAMCO, to bad CSSR unless we connect the FCU to the FDUAMCO and the simple CU to the COAMCO ( eg 2 FCU through FDUAMCO and simple CU to COAMCO is ok , but FCU and 1 CU to COAMCO and 1 FCU and 1 CU to DUAMCO nok) .
Does any have seen that recently ? for nsn it is still under investigation.
Regards
