Data Loss Resolution

Once you isolate a specific SONET section, line, or path, follow these steps to resolve

the problem:

1. Check the fiber cabling for damage or improper use. For example, SONET cables

may be turned beyond their bending radius.

2. Check for signal degradation.

3. Check fiber optic connectors for damage, and make sure they are clean.

4. If you have examined all possible SONET problems, and believe the problem is

related to the PPP link, refer to Chapter 5 for information on troubleshooting the

PPP link.
