[asterisk-users] (OT) DS3 Barrel/T-connector/Adtran MX2800 Problems

[Jerry Jones]

The MUX will give you stats for every line running through it, DS1,  
DS2, and DS3. Start there. What errors is it reporting?

Actually I did that backwards, start with DS3 then do DS1, if 3 has  
issues so will everything else.
