7
ERR009
Alarm code as generated by the PBX.
The format is variable
depending on the PBX. The MDR-2000 outputs codes in the form
M2Kxxx: for internally detected alarm conditions.
8
Pwr
. Failure
Alarm description in freeform as output by the PBX.
The Alarm Code and description fields will contain the exact string that caused the alarm. The Site
Number
field is used in cases where the receiving application
may
wish to poll the MDR-2000.
This enables the application to determine the files in which to store the alarm data.
Note that this record format is compatible with
MDR
's Maintenance and Alarm Reporting System
(MARS) which is the downstream processing module used with the MDR-2000 alarm features.
The MDR-2000 follows a specific algorithm in reporting its alarms and the host system
(MARS)
must accommodate this algorithm.
When
an alarm occurs the MDR-2000 determines
if
an alarm is already being reported.
If
there is
one in progress then the second alarm is not reported. The theory is that
if
one alarm is being
reported for a
PBX
then successive messages within a short timeframe need
not
be annunciated.
If
their recording is important then image collection
must
be enabled.
If
no alarm reporting is in progress then the
MDR-2000
checks the Primary Phone
Number
field,
and
if
valid begins the dialing process.
When
the line is busy
or
some other error is detected the
MDR-2000 will retry autodialing up to the number
ofretries
specified in the
'Set
Retries'
command
(default 5).
If
the Primary Phone
Number
field is empty then it assumes a direct connection and
simply sends the alarm record in the format previously listed with the appropriate protocol layer
(see the Protocol section later in this document for details).
When
the record has been sent as determined by the Primary Phone Number, it then directs its
attention to the Secondary Phone
Number
. The
MDR-2000
uses the Secondary Phone
Number
in
3-7
