    摘要: For protecting traffic from a source client entity (CE1) to a destination client entity (CE2) via an optical transport network and attachment circuits at ingress (A,B) and egress (C,D) nodes, there are multiple paths within the OTN, and the attachment circuits are dual homed. By sending (120) an indication of operational status of the dual homed attachment circuits within overhead associated with the traffic and sent with the traffic through the network, a selection can be made (130) of which of the provided paths and attachment circuits to use for the traffic, based on the indicated operational status, and on OTN fault detection, to protect against a fault. Thus protection can extend across the edge nodes without interworking of separate protection schemes and without a control plane. Traffic flows can be multiplexed at the ingress, with the indication in the overhead having separate indications for each of the traffic flows.

    摘要: A received RF signal can include data information intended for transmission over a wireless communication link (160). The data information of the signal can be processed at a node (130) to produce overhead bits supporting a serial transmission of the data information over a communication medium (140) to another node (150). For example, the data information of the received signal and overhead bits can be combined or framed according to a serial transport protocol for transmission over the communication medium (140) to a target receiver (150), where the original RF signal can be reconstructed.

    摘要: Die Erfindung betrifft ein dienstintegriertes, digitales Nachrichtenübertragungssystem, in welchem an eine Zentrale (Z) eine Vielzahl von Teilnehmern (Tln 1 ...Tln m ) angeschlossen sind. An die Teilnehmer werden mehrere Breitband-Hauptkanäle und ein Breitband-Zusatzkanal übertragen, indem aus diesen Kanälen in teilnehmerindividuellen Breitband-Multiplexern Breitband-Multiplexsignale gebildet werden. In den Breitband-Hauptkanälen werden Fernsehprogramme (FS 1 ...FS n-1 ) oder Bildfernsprechsignale (B an ) übertragen; im Breitband-Zusatzkanal Ton-Rundfunkprogramme und Schmalbandsignale (SD an ). Die Ton-Rundfunkprogramme werden von einer Antennenanlage (Ant) empfangen und in einer Ton-Aufbereitung (Ton-A) zu einem Ton-Multiplexsignal (ST) aufbereitet. In teilnehmerindividuellen Zusatzkanal-Multiplexern wird aus dem Ton-Multiplexsignal (ST) und den Schmalbandsignalen (SD an ) der Breitband-Zusatzkanal gebildet.
    In der Gegenrichtung wird ein Breitband-Rückkanal übertragen, welcher in teilnehmerindividuellen Rückkanal-Demultiplexern in ein Bildfernsprechrücksignal (B ab ) und Schmalbandrücksignale (SD, b ) zerlegt wird.
    Die Zusatzkanal-Multiplexer und die Rückkanal-Demultiplexer sind gleich aufgebaut. So ergibt sich eine große Stückzahl gleicher Bauelemente, welche preisgünstig hergestellt werden können.
