COMMUNICATION PA-
4.
RAMETERS
Introduction
4.1.
This chapter shows how to configure your
Agri-Alert system so that it can transmit
alarm or status reports over the phone line.
For example, the user can call the Agri-Alert
system in order to obtain a status report in
the form of voice messages. The system can
also be programmed to dial a series of phone
numbers and deliver a voice message when an
alarm situation occurs. Make sure to set your
communication parameters properly for these
features to work with your phone system.
Phone communication is only possible if
a plug-in card is inserted in the “PHONE
CARD” port of the Agri-Alert (sec. 1.4.8).
This card is optional.
4.2. Dialout Sequence
When an alarm is set off, the Agri-Alert
launches the dialout sequence (sequence of
phone numbers that are called in case of an
alarm). After a call is answered, the Agri-Alert
either delivers the alarm message as a voice
message or as a pager code.
The system puts an end to the dialout se-
quence when the alarm is acknowledged by
a user (see section 2.4). Otherwise, it keeps
dialing and repeats the dialout sequence fol-
lowing the number of repetitions defined by
the user.
If a phone number is busy, the Agri-Alert puts
it at the bottom of the list and calls all busy
numbers at the end of the sequence (the
number of time busy numbers are called is
defined by the user).
Dialout Sequence Example
Settings:
# of phone numbers = 5;
Call repetitions = 2;
Busy tries = 2
Start of Dialout Sequence 1
Phone number 1
connect
Phone number 2
connect
Phone number 3
busy
Phone number 4
busy
Phone number 5
connect
The Agri-Alert calls all phone numbers
and places busy numbers at the bottom
of the list. It calls back all busy numbers
at the end of the sequence (Busy Tries
parameter=2).
Phone number 3
connect
Phone number 4
busy
Since phone number #4 is still busy and
the Busy Tries parameter is set to 2, the
Agri-Alert calls phone number #4 once
again.
Phone number 4
busy
Phone number #4 is still busy. It is not
redialed since the number of busy line
tries has been reached.
Since the number of call repetitions is
set to 2, the Agri-Alert repeats the whole
dialout sequence from the start:
Start of Dialout Sequence 2
Phone number 1
busy
Phone number 2
connect
Phone number 3
busy
Phone number 4
connect
Phone number 5
connect
The Agri-Alert calls all phone numbers
and places busy numbers at the bottom
of the list. It calls back all busy numbers
at the end of the sequence (Busy Tries
parameter=2).
Phone number 1
connect
Phone number 3
connect
End of Dialout Sequence
The Agri-Alert puts an end to the dialout
sequence when the number of call repeti-
tion is reached or if someone acknowl-
edges the alarm (the alarm can either
be acknowledged on the phone or on
site). If no acknowledgment is received
for the alarm at the end of the dialout
sequence, the Agri-Alert automatically
acknowledges it.
