hi all,
we have one frame relay link to customer with the following connection
router -----csu/dsu(lease line)--------frame relay node/cloud
the problem is on serial0/0(connected to csu/dsu) the input errors and
interface reset is increasing tremendously, ping test resulted in 6 packets
dropped out of 1000.
service provider isolation test on the lease line found no error detected.
then we did a loopback on csu/dsu facing router, the result is as below,
where
after a while we still receive input errors and interface reset.
could it be because router problem or csu/dsu..?
prompt response needed since this customer is currently running on ISDN
backup.
thanks
