Most likely physical layer issues.  Wet copper cable pairs (T-1), dirty
fiber (optical), etc.  Can you be more specific as to the nature of the
link such as speed, internal cable or purchased WAN link from a carrier,
etc.?

You'll likely have to take it out of service and run loopback tests to
isolate and repair the problem.

If this is a new circuit turn-up it could be a configuration issue such
as framing, linecode, clocking, etc.
