CHAPTER THREE: COMMUNICATION PARAMETERS
3.1 INTRODUCTION
This chapter explains the setup required for communicating alarm messages and
status reports over the telephone lines. For example, the user can dial into the Agri-
Alert system and obtain status reports over the phone 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. In order for these features to work
properly with your phone system, care must be taken to assign the proper values to
the communications parameters.
Dialout Sequence:
This is a sequence of telephone numbers that are called in a speci-
fied order when an alarm has been validated by the system. When a phone number is
called, the Agri-Alert can perform different functions: deliver a voice message, send
a pager message, etc. The dialout sequence can be stopped at any time by acknowl-
edging the alarm (see Section 1.8). Otherwise, it will continue until all the phone
numbers have been called and until the entire sequence has been called a set number
of times (equal to #of call repetitions parameter). When a busy signal is returned on a
line, the phone number is placed at the end of the sequence. If the Busy Line Tries
parameter is not zero, the system redials the busy numbers once all of the other
numbers have been called. This is repeated according to the value of Busy Line Tries.
Once the sequence is finished, the entire process is repeated until it has been com-
pleted a number of times equal to the #of call repetitions parameter. If new alarms
are detected during a dialout sequence, the entire dialout sequence is restarted.
START OF DIALOUT SEQUENCE # 1
Example:
Number of telephone numbers = 5
#of call repetitions = 2
Busy Line Tries = 2
Phone number #1
Phone number #2
Phone number #3
Phone number #4
Phone number #5
connect

busy

Phone numbers #3 and #4 are busy. They are placed at the end of the list and
redialed since Busy Line Tries = 2.
