    摘要: in a network of communication rings (Rl ... R7, BB) interconnected by bridges (B1 ... B4), access to each ring is regulated by a circulating token which is normally issued at irregular intervals depending on occurence and length of messages. To enable communication of messages which have to be transmitted synchronously, i.e. at regular intervals, each ring has a synchronous bandwidth manager SBM which periodically issues a token for only synchronous information. Each SBM is located in a bridge node (13, 15) but only one of them which is located in a particular bridge node (15) is the master SBM from which all other SBM's are synchronized, using a synchronous token and/or special synchronization circuitry in each bridge. This allows to have a common period in the whole network for handling synchronous information, even if all rings have different bit rates.

    摘要: 5 Das Übertragungssystem weist eine mit einer Vermittlungseinrichtung (EX) verbindbare Vermittlungsanschlußeinrichtung (COT) auf, die über zwei optische, parallel angeordnete Leitungen (RL1, RL2) mit mehreren abgesetzten Stationen (RT1...RT3) verbunden ist. In der Vermittlungsanschlußeinrichtung (COT) ist eine ankommende optische Verbindung (RL1) im Sinne des Bildens eines gefalteten Ringnetzes (FRN) auf die weitere, abgehende optische Leitung (RL2) geführt. An die abgesetzten Stationen (RT1...RT3) sind einzelne Kommunikationsendgeräte des Kommunikationsnetzes anschließbar. Mit Hilfe von im Übertragungssystem angeordneten Schaltmitteln (LB1...LB3) und Steuerungen (ZS, ST) kann das gefaltete Ringnetz (FRN) bei Störungen der optischen Leitungen (RL1, RL2) bzw. der übertragungstechnischen Komponenten (OR, OT) aus den noch intakten Ringnetzteilen erneut ein gefaltetes, konfiguriertes Ringnetz gebildet werden. Das Übertragungssystem ist besonders vorteilhaft in weiträumigen Kommunikationsnetzen einsetzbar und kann in Abhängigkeit von der Anzahl der anzuschließenden Kommunikationsendgeräte hinsichtlich der erforderlichen Übertragungssicherheit angepaßt werden.

RT3)。 在光线路(RL1,RL2)或传输中涉及的技术组件(OR,OT)发生故障的情况下,可以从仍然完整的环网部分重新构建折叠配置的环网络,借助于 开关装置(LB1 ... LB3)和控制器(ZS,ST)。 传输系统可以特别有利地在广域上延伸的通信网络中使用,并且可以根据要连接的通信终端设备的数量来适应所需的传输可靠性。

    摘要: The present invention relates to a communication system comprising a plurality of communication units (1, 2, 3) which are coupled together by coupling means (4), for example in the form of a physical conductor. Each unit is provided with first means (10) for receiving auditive information and/or second means (11) for transmitting auditive information. Certain units are allotted a group assignment and are arranged to establish a confer­ence call facility, where an analogue signal deriving from transmitted auditive information is subjected to a sampling process. For the purpose of transmitting audi­tive information and/or for receiving auditive informa­tion, all units (1, 2, 3) associated with the group are arranged to utilize one and the same time slot (t3) in a time frame used for the sampling process, such that when information is transmitted simultaneously from two or more units (1, 2) the sampling contributions are summated within time slots (t3) via the unit-interlinking-means (4), so that a plurality of information signals can be evaluated simlutaneously via the first means (10) of the unit (3).
