HOW TO READ THIS CHAPTER
In the programming procedure, the meaning of (1), (2), and marking are as follows:
(1): 1st Data
(2): 2nd Data
: Initial Data
With the system data clear command (CM00, CM01), the data with this marking is 
automatically assigned for each command.

FAULT MESSAGES
General Description
This feature stores fault information into the Fault Store Memory and displays the fault informa-
tion 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 into four parts and displayed on four screens.

(2) Display Format using MATWorX Studio
The fault information displays in the order that faults occur. 
Service Conditions
(1) Printout of fault information is possible through the printer connected to the MAT.
(2) The maximum number of fault information that can be stored is 64. If the stored information 
exceeds 64, the storing method (either overwriting new data or not storing new data) can 
be selected by CM08>451.
(3) To provide 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 for each fault kind.

Programming Procedure
DESCRIPTION DATA
Enable the fault information storage 
feature.(1)
(2)450
1 : To be provided
Specify the processing at the time of 
fault storage memory overflow.(1)
(2)451
0 : No fault information is registered 
in case of fault memory overflow
1  : Fault information is overwritten in 
case of fault memory overflow
Assign which kind of fault information 
is stored into the fault information 
memory, and which kind of fault indi-
cates an alarm.
NOTE 1:Even if the external alarm
may be set as MN or MJ
alarm for system initialized
(1st data=01), no alarm is
output in the case of Power
On, Reset key operated, ini-
tialization 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 predeter-
mined number” is assigned
by CM42>06, 07. When
CM42>06, 07 is assigned,
the 2nd data of CMEA Y=2
simply means the fault infor-
mation is to be registered
into Fault Memory. In this
case, Alarm Kind cannot be
changed.•

DESCRIPTION DATA
NOTE 3:The External Alarm Kind for
“Number of lockout stations
was more than predeter-
mined number” is fixed as
MN. The 2nd data of CMEA
Y=2 simply means the fault
information is to be regis-
tered into Fault Memory.
In this case, Alarm Kind
cannot be changed.
NOTE 4:The External Alarm Kind for
“Number of faulty trunks
was less than predeter-
mined 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, Alarm
kind cannot be changed.(1) 25 : Number of lockout stations was 
more than predetermined number

NOTE 5:
The External Alarm Kind for

To clear the MJ/MN alarm by external key, perform the following programming.
DESCRIPTION DATA
Assign the card number for external 
key interface (PN-DK00) to the 
desired LEN.
NOTE 1:The card number of the ex-
ternal key interface (PN-
DK00) must be assigned to
the first LEN (LEVEL 0) and
third LEN (LEVEL 2) of each
card slot.
