Data exchange for meter reading, tariff and load control - Direct local data exchange

Specifies hardware and protocol specifications for local systems. Deals with direct local systems, in which the hand held unit is connected to one tariff device only at a time. Connection can be permanent or disconnectable through an electrical or optical coupling. The protocol took as its basis the basic reference model for communication between open systems (OSI).
