Greetings,

we have three spans (Aspect) set up with the Telco as NFAS. No issues with the Primary or Secondary span. Ongoing issue with third span where the span on the Aspect alarms, sometimes drops but stays up for the most part. We replaced the card (had two spans on it, no issue with other span on it), the cabling and the paddleboard. Telco replaced a card on their end and ran clean for close to two months. Problem came back, telco replaced some wiring the found faulty. Span completely dropped a couple of hours after the wiring was fixed and has continued to drop whenever we turn our end back up. Any thoughts as to what might be causing the issue?
Thanks
Dan
