Troubleshooting Guide
The following guide is set up as a series of possible conditions, causes
and suggested fixes or steps in finding the failing unit. Because of the
different manufacturer's equipment involved in typical multiplexer
networks, you may encounter "finger pointing" as to who is at fault. Who
is at fault is not as important as getting you back on line as soon as
possible. The intent of the following guide is to indicate the most
probable cause of specific error conditions, but, since similar conditions
may account for a number of different failures, the following guide is just
that: a guide to troubleshooting.
The parts of your mux network are:
•
Channel devices (printers, terminals, pc's, etc.)
•
Channel Communications (RS232 cabling,synchronous
modems, etc.)
•
MultiMux control units
•
Synchronous link modems (internal Multi-Tech or external)
•
Composite link communications line (2-wire or 4-wire leased
line with internal or external modems)
•
Dial-up composite link communications line with internal or
external modem
•
Digital composite link communications line with internal or
external DSU
Once you have found the probable cause of your problem, refer to the
specific manual chapter for additional help or contact our Technical
Support, refer to Chapter 8.
