Software Configuration 35
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 format is described in the Element ID field.
DIRECT: Sends reports to a printer or terminal connected directly to the
supervisory port.
COA messages are reported in the following format in the DIAL or DIRECT
modes only:
Element ID HH:MM:SS MM/DD/YY
NET Alarms: alarms
DTE Alarms: alarms
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
DTE Alarms: DTR
The user-programmable Element ID string (see Utilities Screen on page 37) 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).
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 primary number again. When a connection
is detected, the unit outputs the notification message and disconnects.
Initialization String. The modem initialization string is entered in this field. Refer to
the modem’s documentation for further information. The default setting is
ATEQ0V1.
Disconnection String. This field identifies the character string to be output when
the modem session is terminated. The default setting is ATH.
