Abstract:

A switch matrix for connecting any one of a large number of communications lines, transmitting a message header, with any other non-busy one of the lines. A plurality of connection links are provided. A message header identifies a transmitting line carrying a request-to-send signal, and the address of a desired receiving line. Means responsive to a received header determines the availability of an unconnected link and the not-busy condition of the desired receiving line, and connects a selected link from the transmitting line to the desired receiving line, whereby to permit the transfer of information. A link-activity checker operates automatically to disconnect a link when transmission of data through the link ceases.
