Client Cannot Reach Dslam, Layer 1 ± Physical | Paradyne 8510 RADSL

Diagnostics and Troubleshooting

Client Cannot Reach DSLAM

This section examines the Service Node-to-DSLAM segment of the network.

NOTE:

On the DSLAM, verify that the DSL link is up and that there is a MAC address for the client (screen B-E-B).

ÐIf the MAC address appears, and all items in the previous section have been examined, it is safe to assume that this network segment is functioning. Skip this section and go to Table 6-6,DSLAM-to-IPC Segment.

ÐIf a MAC address does not appear, check the items in Table 6-5.

Solution

Layer 1 ± Physical

1.On either the Service Node or Access Node, if the ALM LED is on, power the system off and then on again. Conduct a self-test from screen D-A. Go to screen D-Bto learn more about the cause of the alarm.

2.Perform a Service Node self-test at the DSLAM (screen D-D) to test memory and start up parameters.

3.If the PWR, ALM, LINE and TST LEDs remain lit, make sure the correct power adapter is being used and that the correct firmware is on the Service Node (screen B-F). Make sure the correct port is selected.

4.Go to screen B-A-Cto view the system log.
