124 Remote IPE maintenance
On-line diagnostic test are performed with the Microlink up and are not
traffic affecting. If the Microlink is down, the system assumes that there is
a loopback condition.
The off-line commands are:

On-line diagnostic tests:
The on-line diagnostic tests are conducted with the Microlink up and are
not traffic affecting. Such a test is TEST FIBER (T FI). It tests near-end
Fiber Remote Multi-IPE Interface, the fiber-optic link, and the far-end Fiber
Remote Multi-IPE Interface. This test may become traffic affecting if during
the test the redundant fiber-optic link fails.
Isolating and correcting faults
Based on whether Remote IPE equipment has just been installed and is
not yet operational or has been operating correctly and is now faulty, the
most probable cause of failure can be determined.
Types of faults
Problems can occur in the following areas:
•
•
•
The types of faults to isolate and correct depend on when the faults occur
during installation or in a previously operating system. For example, in a
newly installed system, the fault can be in any or all of the three areas;
however, in a previously operating system, the fault is probably in the
hardware.
