Stephen, Also, what has the carrier told you about this circuit? Most "carrier-class" transport equipment can report the types of errors being incurred and where they first appear in the network. For instance, coding violations, framing errors/violations, simple FCS failure, etc.
Also, did your "receive frequency" correct to within +/-900 bps of 44.736 mbps on each end when you set the 7500 for internal clock?
