Abstract

Gives data link layer message structure, formats and transmission procedures which should be used at standard serial data interfaces in alarm transmission systems where the transmission network employed does not offer a standard protocol. Equally applicable to the transmission of alarms and other messages to/from intrusion, fire, access control and social alarm systems and to the transmission of information to/from other similar systems.
