Analogue extensions don't ring 1

[francescod]

Good day everyone,

I have a problem with a MD110 PBX version CXP1010015/5/BC11SP11/R1A
This PBX has 1 LIM with 2 Magazines
In the MAG 0 there is 1 ELU29 in position 1-0-60 whose extensions work regularly.
In the MAG 1 there are 3 ELU29 in position 1-1-50, 1-1-52 and 1-1-60;
the first 8 analogue extensions of the ELU29 in position 1-1-50 work regularly while the others don't ring.
I already changed DSU board and RG5DC in the MAG 1, but no results.
At the moment there are these alarms:

Could the alarm on the DSU board in MAG 0 be the cause of the malfunction?

Thank's for help.

Fixed, the problem consisted in an incorrect setting of the dip switches in RG5DC board
Thank's!
