We have an MGC-50 connecting to an Adtran Atlas 890 then out to the VC world. When monitoring conferences, at times the "!, Faulty Connection" appears for a site. When we look at the properties on the Connection Info 1 tab in the H221 Counters area we see various versions of all 4 check boxes checked and increment numbers increasing for the L&R Sync Loss and L&R Video Sync Loss.
What I need to know/find out is what that means. The references I can find states that there is a either General or Video synchronization issue with the MCU or participant site. Where do I look for issues to resolve?
