5 Fault tracing
5.1 Using information on
the built-in MMI
If an internal fault has occurred, the built-in MMI displays information
under:
Terminal Status
Self Superv
Here, there are indications of internal failure (serious fault), or internal
warning (minor problem).
There are also indications regarding the faulty unit, according to Table 1.
You can also connect the internal signals, such as INT--FAIL and INT--
WARN to binary output contacts for signalling to a control room.
In the Terminal Status information, you can view the current information
from the self-supervision function. Indications of failure or warnings for
each hardware module are provided, as well as information about the
external time synchronization and the internal clock, according to Table 1.
Recommendations are given on measures to be taken to correct the fault.
Loss of time synchronisation can be considered as a warning only. The
terminal has full functionality without time synchronisation.
5.2 Using front-connected
PC or SMS
Here two summary signals appear, self-supervision summary and CPU-
module status summary. These signals can be compared to the internal
signals as:
