Fault isolation and correction using MMI maintenance commands
Testing and troubleshooting of the Fiber Remote Multi-IPE Interface
units and Remote IPEs can be performed from a local or a remote MMI
terminal by typing MMI commands on the terminal without loading system
diagnostic programs (overlays).
These commands provide current equipment status, perform superloop
and link testing, check equipment performance, print messages from log
files, and clear alarm and error logs.
Procedure 41
Displaying alarm and error logs to check the performance history
Step
This procedure uses MMI commands to display the superloop and the fiber-optic
link performance history.
