Clear the stats on the interface.
If you see input CRC count rising the
report the T1 to the carrier (telco).
It appears that you still have carrier (DCD)
so you still have a T1. But I cannot tell if it is bad
since the counters were cleared 18 hrs ago, and
I don't know what type of testing that may have been
done that might have caused the errors being seen.
