The Management Ports screen (Figure 4-16) sets the fol-
lowing parameters for the Call On Alarm (COA) connection
on the SUPV port.
Element ID: This field allows the entry of an ASCII string
(up to 29 characters long) which identifies the unit to the
device receiving the alarm notification messages.
Call on alarm messages are reported in the following format
in the Dial or Direct modes only:
Element ID HH:MM:SS MM/DD/YY <CR> <LF>
NET Alarms: alarms <CR> <LF>
DTE Alarms: alarms <CR> <LF>
where (alarms) is a string consisting of some or all of the
identifiers LOS, OOF, RAS, AIS, UAS, ERRS, or NONE.
The following is an example:
Joesunit 17:24:55 08/04/93
NET Alarms: LOS AIS ERRS
DTE Alarms: LOS Port1
The user-programmable Element ID string is transmitted
first to allow the COA function to send a message with a
specific meaning to some host (such as a log-on message).
The identifier ERRS represents an alarm that is
caused by ES, SES, and /or BPV errors.
COA Connection: This field controls the remote alarm
reporting. The ASCII alarm report type is set by the follow-
ing choices:
DISABLED - Alarm reporting is disabled.
DIAL - Sends reports through an attached AT command set
compatible modem connected to the SUPV serial port,
which must dial out to a remote modem. The message for-
mat is described in the Element ID field.
DIRECT - Sends reports to a printer or terminal connected
directly to the supervisory port.
Primary Dial String, Secondary Dial String: These fields
are ASCII strings for the primary and secondary call on
alarm phone numbers used in the DIAL mode. The strings
must include the ATDT command prefix.
The unit makes three attempts to connect using the primary
number. If all three attempts fail, the unit makes three
attempts to connect using the secondary number (if it is not
blank). If the secondary number fails, the unit waits five
minutes and then attempts to communicate using the pri-
mary number again. When a connection is detected, the unit
outputs the notification message and disconnects.
