NEC UNIVERGE SV8300 System Maintenance Manual page 24

NOTE 4: Confirm the following fault information, when you check Remote Unit operations by survival
mode as fault information from PCPro/CAT in Remote UNIT over IP.
001: System Reset
042: Communication error occurrence between Main Unit and Remote Unit
052: Communication error restoration between Main Unit and Remote Unit
When Remote Unit starts the survival mode operation, the fault information "Reset by CAT or
PCPro" (Fault occurrence kind No. 001) is registered to the CPU blade of Remote Unit.
In addition, "Communication error occurrence between Main Unit and Remote Unit" (Fault
occurrence kind No. 042) is registered to the CPU blade of Main Unit at 20 seconds later from
the predetermined time set by CM0B Y=1XX>80.
Remote Unit on survival mode checks at every 30 seconds if the communications to Main Unit
are possible. When the Remote Unit regards that the communications are possible, "Commu-
nication error restoration between Main Unit and Remote Unit" (Fault occurrence kind No.
052) is registered to the CPU blade of Main Unit at 20 seconds later from the predetermined
time set by CM0B Y=1XX>80.
NOTE 5: About long call duration of trunk call (fault kind: 04A)
• When Long call duration failure occurs, "Failure occurred" is displayed on the PCPro.
• After a trunk is seized, when the trunk is seized longer time than the monitoring time (1-60
hours) set by CM42>182, the call is registered as long call duration failure. However, there
is a tolerance up to 30 minutes between monitoring time set by office data and actual time to
be registered.
NOTE 6: When SRAM memory is unsettled at the time that the system is started up, this fault information
can be output.
(The SMDR data in SRAM memory cannot be guaranteed to save when the system is power-off
for over a week, because the battery of SRAM runs down about a week later.)
NOTE 7: Failure cannot be judged correctly when SRAM data all clear by CM00>02 is never executed.
NOTE 8: The External Alarm Kind for "Number of lockout stations was less than predetermined num-
ber" is fixed to No Alarm. In the case of this office data, even if the 2nd data is set to 0/1/2/3, it
simply means that the fault information is to be registered into Fault Memory. In this case, Ex-
ternal Alarm Kind cannot be changed.
