OL-2365-01
Steps to Take
If errors or retraining occurs while the line is ringing, use the dmt interleaving-delay
4.
command to turn on interleaving.
In interface configuration mode, reset the port by executing the shutdown command
5.
followed by the no shutdown command.
Connect the customer to a different port on the Cisco 6260. If the modems train,
6.
replace the line card with the faulty port.
7.
Troubleshoot the CPE device and the loop as described above under the symptom
"You suspect a problem with the CPE or the subscriber loop." section on page
Replace the line card.
8.
Remove the card and reinsert it, pushing firmly on both the top and the bottom of the
1.
faceplate. (The card might jam in the slot if you apply pressure to the top only.) If the
chassis is full, you might need to push sideways to insert the card.
2.
Inspect connectors on both the card and the backplane, looking for obstructions, bent
pins, or other damage. If you find damage to a line card connector, replace the line
card. If you find damage to a backplane connector, contact the Cisco TAC.
There may be a fault in your backplane. Contact the Cisco TAC.
