摘要

The invention relates to a local communication network in a loop conveying at the times the clinical and in the form of speech signals telephone, 1984. / p & & p & this network comprises a loop l formed by sections of the line 1, placed in series by repeaters r1 to rn allowing access to the loop of the stations s1 to sm and closed on it - even by a loop control unit ucb introducing a synchronization signal periodic and the delay necessary to form a frame having a first segment used in "packet" and a second segment used in "circuits". In order to increase the volume of traffic convenience, the loop is purgee of the bytes in "circuits" by several points by bridges p1 to p4 which draw the bytes of the second segment circulating in the sector of upstream and fit the bytes circulating in the sector of downstream, a time-division ct ensuring the interconnection between the sectors and with the packaging. / p & & p & the invention applies to the multiservice local arrays.
