AT&T Technologies has implemented hardware and software components that will provide an economical Local Area Data Transport (LADT) service. The AT&T Technologies LADT Generic 1.0 is composed of a No. 1 PSS packet switch, one or more statistical multiplexers called Data Subscriber Interfaces (DSIs), and an Administrative Processor (AP) responsible for the administrative functions of the network. This paper describes AT&T Technologies LADT Generic 1.0 hardware and software architectures of the DSI and AP components of the network.
