This paper proposes a network architecture consisting of transport core systems and service adaptation systems for realizing a multi-service network based on asynchronous transfer mode (ATM) technology.
The key service switches and service interfaces of the network are described.
In addition, the paper discusses the network's multi-service operation feature, along with a detailed summary of the specific operations and functionalities already developed.
A brief introduction of ATM Multiplexer/Switching System 5000 series, which are designed around this architecture, is also given.
