摘要： Data to be switched is preceded by a header containing routing information for establishing a connection via a switch, and is accompanied by additional information which indicates the start of the header, in response to which a connection is established, and the end of the data, in response to which the connection is terminated. The switch is a non-saturating, non-blocking, full matrix time switch which uses the routing information to establish a connection within one tdm frame, whereby connections for data of any type (including switch control information) and of arbitrary duration can be handled efficiently. An incoming channel can be connected to any free channel or to a specified outgoing channel of any output port, and contention resolution is provided for simultaneous requests for connection to a single outgoing channel. Interconnections among crosspoint nodes are reduced and simplified using token ring and systolic interconnection techniques.
