FAULT MESSAGES
General Description
This feature stores fault information into the Fault Store Memory, and displays the fault
information on the Maintenance Administration Terminal (MAT) or the Customer Administration
Terminal (CAT).
The display format is shown below:
(1) Display Format on CAT/MAT by Command Operation
The fault information is separated intofour parts, and displayedon four screens.

(2) Display Format for users with MATWorX or MATWorX Studio:
Fault information is available via MATWorX or MATWorX Studio. The fault information is
displayed in the order thatfaults occur. For additional information, please consult theOnline
Help included with MATWorX and MATWorX Studio.
Service Conditions
(1) Print out of fault information is possible through the printer connected to the MAT.
(2) A maximum of 64 faults can be stored. If the stored information exceeds 64 faults, the
storing method (either overwriting new data or not storing new data) can be selected by
CM08 >451.
(3) For providing external alarm indication, equipment such as an Alarm Display Panel must be
installed. External alarm indication is provided using a contact to ground at the main
distribution frame. One contact is needed for minor alarms, and one contact is needed for
major alarms.
(4) The alarm kind (Major Alarm, Minor Alarm or No Alarm Indication) can be programmed by
CMEA Y=2 or set by Fault Storage Add-In of MAT for each fault kind.
Programming Procedure
(1) To set the fault information storage from the CAT/MAT by Command Operation:

NOTE 1: Even if the external alarm is set as MN orMJ alarm for system initialized (1st data=01),
no alarm is output in the case of Power ON, Reset key operated, initialization from the
MAT/CAT, and initialization by MP SW3 switch selection.
NOTE 2: The External Alarm Kind for “Number of faulty trunks was more than predetermined
number” is fixed as MN or MJ by CM42>06, 07. When CM42>06, 07 is assigned, the
2nd data of CMEA Y=2 simply means the fault informationis to be registered into Fault
Memory. In this case, External Alarm kind cannot be changed.
NOTE 3: The External AlarmKind for “Number of lockout stations was more than predetermined
number” is fixed as MN. The 2nd data of CMEA Y=2 simply means the fault information
is to be registered into Fault Memory.
In this case, External Alarm Kind cannot be changed.
NOTE 4: The External Alarm Kind for “Number of faulty trunks was less than predetermined
number” is fixed to No Alarm. The 2nd data of CMEA Y=2 simply means that the fault
information is to be registered into Fault Memory. In this case, External Alarm Kind
cannot be changed.
NOTE 5: The External Alarm Kind for “Number of lockout stations was less than predetermined
number” is fixed to No Alarm. The 2nd data of CMEA Y=2 simply means that the fault
information is to be registered into Fault Memory. In this case, External Alarm Kind
cannot be changed.
DESCRIPTION DATA
Assign the number of stations in line
