In order for successful communication to take place, both
the source of the data (the Digital Communicator) and its
destination (the Central Station Receiver) must "agree" on
the
protocol
being used. In the early days of digital
communication, Central Station Receivers used separate
Line Cards, each specifically designed for a single reporting
format – a format the Central Station chose to process.
Thus, a typical receiver might be equipped with a
"
Radionics
-only" Line Card, a "
SESCOA
-only" Line Card,
and an "
ADEMCO
-only" Line Card. Furthermore, all
subscriber accounts using a particular reporting format
would have to be programmed to dial the "phone number"
corresponding to the appropriate Line Card – otherwise the
successful communication of alarm reports would be
impossible.
