We have Mx-One 4.1 SP3 and had been experiencing :
1. poor quality speech (crackle / static interference for short intervals during conversation). We have just upgraded to the R9 FW for the cards and corresponding FW for the base stations and are monitoring calls before deciding whether the problem is fixed.
2. synch ring faults on ELU31/3 using ACDM.
We have been told that our synch ring cable length is too long although we have been using the same synch ring for many years through BC10, BC11, BC12 and BC13 with no problems. It shows up as 58 ACDM delay units on CXCFP. Is this too long, too much delay?
3. blocking of all five ELU31 cards in one of our LIMs if the MGW restarts. We need to loopback the synch ring to clear the blocking when this occurs.
4. Is the document published 16th Feb and referred to above, available here in English? We do not have access to Info Channel.
