Data Collection
minimum constraints but are otherwise in the correct format are not collected by the image collec-
tion when discarded, only records that did not meet the PBX's CDR format are saved.
3.1.3 Data Translation
The actual process
of
translating PBX specific records into Expanded
MDR
Standard Format is
relatively straight forward. Each field
of
an incoming record is analyzed as necessary to derive the
information for the output record. The translation is dependent on the PBX being supported. Any
fields which are not present, that can be defaulted, are set to specific values.
The customer number is defaulted to '00', the record number is assigned a sequential 3 digit
number, and the auxiliary
ID
is defaulted to spaces.
In
addition, incomplete fields, such
as
a time
field with no seconds, has the seconds field set to '00'.
Finally, the originating and terminating
ID
fields are right justified and zero filled
if
they are shorter
than the maximum size. The digits dialed/account code field is terminated by a Carriage-
Return/Linefeed pair.

Alarm Annunciation
When alarms are enabled the Alarm Table (see Interactive Monitor, Set Alarm, Set Primary Phone,
Set Secondary Phone and Alarm Table commands for details) is scanned for each image record that
is processed. When an entry in the table matches the starting characters
of
the image record then
the repeat count for that entry is decremented. When the repeat count reaches zero it is reset and an
alarm is raised. The MDR-2000 will then use the telephone number stored with the Set Primary
Phone and Set Secondary Phone commands to dial a Hayes compatible modem and then dump an
alarm message.
Note that these records are only retained in the MDR-2000's buffer
if
image collection is enabled
(See Set Image command).
In order to successfully use this capability there must be a dedicated modem and computer at the
receiving end to accept the alarm message. The MDR-2000 will output the formatted message
when the modem at the receiving end answers the telephone.
The message is output with the standard MDR-2000 protocol layered around the alarm message as
follows:
