3. Observe that zero errors are indicated on the receive side of the test set.
If an error count occurs, check all option selections and repeat steps 1 through 3.
If the error count persists, check the following:
a. Make sure the test set is correctly set up.
b. Make sure the test set cable is correctly connected.
c. Make sure the module under test is correctly installed.
d. Make sure the cable assembly is firmly and correctly connected.
If the error source is localized to the module or the cable assembly, return the
defective component to RFL for repair. If an error count persists after these steps
have been taken, check for an outside error source.
TROUBLESHOOTING
If there is an apparent malfunction, first check that the configuration is appropriate for the transmission
system in use, and that the transmit and receive configurations are identical.
Problems may occur at the common equipment or facility level that may affect the operation of this
module. Refer to the “Maintenance” section in your multiplexer manual for system analysis
procedures.
Use the following procedure to determine whether a problem is being caused by the OCUDP or
by some other part of the system.
1. If more than one module is on the same time slot, remove those modules that are known to be
good.
2. Perform a local loopback test, as described in steps 1 through 3 of the Local Loopback test
procedure.
3. If the loopback test indicates that the module is functioning properly, then check that the
terminal equipment is functioning properly. If so, then the test is complete. If not, then check
for an outside error source.
4. If the error count persists, then swap modules. Replace the module with another that is known
to be functioning properly. If the replacement module is OK, then use the Repair/Return
procedure in the General Information Section of the manual to return the defective module to
RFL for repair.
5. If proper function is not obtained, perform individual multiplex tests as described in the
multiplexer manual. If an error count still persists after these steps have been taken, then check
for an outside error source.
