Fault location
There may be situations when there are problems with a specific
external line or other interference to equipment failure. There are
two ways to verify faulty external lines:
If static or other interference is noticed while connected to an
external party, make note of the route number, line module
numbers and the external line number.
If all external lines are busy more frequently than seems reasonable,
or there is any reason to suspect a problem in a specific external
line, each one may be checked, individually, using the procedure
described in section “Via a specific external line” on page 75.
When reporting the fault, consider the following
• Location
• Route number, line module numbers and external line number
• Person reporting the trouble
• Date and time reported
• Person correcting the problem
• Date and time corrected
• Fault reported
•Fault found
