5.5.2 EAC-2100 Originating (Continued)
Successful Call Sequence. When an auto-dial call is made, the following
sequence occurs:
1. As the call is auto-dialed, the local console displays DIALING REMOTE
LINK. (<CR> from the local link at this point will abort the attempt.)
2. After the number is dialed, the EAC-2100 waits up to 90 seconds for a
remote modem to answer and establish a connection.
3. Five seconds after connect, the EAC-2100 automatically lists the alarm
report. The report is echoed locally.
4. If the connection stays up for the duration of the report listing, the attempt
is considered successful. The EAC-2100 disarms itself after a successful
call to prevent duplicate reports.
5. After the report, the system waits up to 60 seconds for a <CR>. If a
<CR> is received, a normal interactive session begins. Otherwise, the
EAC-2100 ends the call.
6. If a second dial-up phone number is programmed, the sequence will be
repeated using the second number.
Unsuccessful Call Attempts. The system will abort the call and consider the
attempt a failure if either of the following occurs:
• The modems do not connect within a set period of time (the programmed
"Max Auto-Dial Trial Period" parameter, default 90 seconds).
• The modems connect, but lose the connection before the entire report is
listed.
After a failed attempt, the system will display the message ORIGINATION
ATTEMPT FAILED on the local console. It will then wait a specified period of
time (the programmed "Delay Between Auto-Dial Retries" parameter). If all
the conditions for making the call are still in effect, another attempt will be
made.
One way to test the call origination feature is to artificially create an alarm by
setting the +28 Volt Supply - Low Alarm Point to +35 Volts.
