Solution
Check fiber-optic link connections and go to
Procedure 42 "Checking the superloop and the
fiber-optic link status" (page 135)
the status. Then go to
the superloops and the fiber-optic link" (page
137) and Procedure 44 "Testing the superloop"
(page 138) to test the equipment.
Check the link cable connections to the
Fiber Remote Multi-IPE Interface unit. Go to
Procedure 43 "Testing the superloops and the
fiber-optic link" (page 137)
"Testing the fiber-optic link" (page 140)
the fiber-optic link.
Enable the alarms, if disabled. Wait for the test
to complete and analyze the results of the test.
Otherwise terminate the off-line test by entering
S (stop) command at the MMI terminal.
Define a unique address correctly. Observe
the XMI messages on the MMI terminal and
check the description of these messages
listed in Software Input Output Administration
(NN43001-611) () . Use this information to
locate and correct the fault.
Go to Procedure 39 "Checking the Peripheral
Controller card tracking status" (page
and 8 to check tracking and loopback. Also
refer to "Peripheral Controller HEX codes and
cable connection diagrams" (page 149)
list of codes. Based on the test results and
maintenance display codes description, take the
appropriate action and resolve the problem.
Note various error messages. Refer to Software
Input Output Administration (NN43001-611)
() for a list of these messages and their
description. Based on the code's description,
take the appropriate action to resolve the
