Troubleshooting
Introduction
In the process of establishing a link, various problems may arise, either single link problems or
•Two units are connected but there is no radio link between them
•Poor performance of a radio link
•There is a radio link but the LIU does not operate or is not synchronized
•There is a radio link and the LIU operates, but the end equipment does not synchronize
•The radio link is stable, but the error rate on the end equipment is unacceptable
•The radio link is fine, but the voice quality/data rate is poor, or the end equipment loses synchronization from time to time
•The system resets with an error message
•One or more links function (are synchronized), but when adding another link performance degrades
•The Fractional E1/T1 link is synchronized, but one or some systems that are connected to the end equipment (i.e. telephone, fax, voice mail) is not working properly
This chapter helps you to identify the source of the problems, and provides a recommended solution.
Use this chapter as guidelines to troubleshooting, but remember that at any given site more than one of these problems can arise, and in different variations.
