Chapter 5 Troubleshooting

FRU-Specific Problems

Modems train at a low bit rate,
modems retrain continuously, or
the line experiences too
many errors (continued).

4.

If errors or retraining occurs while the line is ringing, use the

dmt interleaving-delay

command to turn on interleaving.

5.

In interface configuration mode, reset the port by executing the

shutdown

command

followed by the

no shutdown

command.

6.

Connect the customer to a different port on the Cisco 6260. If the modems train,
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 5-11

.

8.

Replace the line card.

Card cannot be fully inserted
into its slot.

1.

Remove the card and reinsert it, pushing firmly on both the top and the bottom of the
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.

Card experiences problems in
one slot but operates normally
in another.

There may be a fault in your backplane. Contact the Cisco TAC.
