Document Type and Number:
Japanese Patent JP3010586
Kind Code:
B2
Abstract:
Integrated digital communication system for an integrated services time-division telephone installation interconnecting a plurality of input/output units (2, 3, 6, 7) of line or junction equipment type, for establishing communications between telephone sets or terminals (4, 5) by means of a control unit (12) and possibly one or more auxiliary units (13). This system comprises a serial bus and a parallel bus to which all the units are identically connected via interfaces (14). Each interface is able to make use of one or other of the buses for its transmissions, either in isochronous form by way of at least one isochronous channel which is then reserved for it from the parallel bus, or in asynchronous form on the paths then available from one or other of the buses whose availability this interface has temporarily obtained through a procedure of contention between interfaces.
