Title (EN) TRANSMISSION SYSTEM
(FR) SYSTEME DE TRANSMISSION
Abstract:
(EN) The continuity of divided multiplex signals is maintained and an original large-capacity multiplex signal is restored to realize efficient large-capacity transmission. A signal dividing means (11) divides a multiplex signal and generates a plurality of division signals of STS or STM transmission interface type. An assurance information adding means (12) adds assurance information which assures the continuity of the division signals to the division signals to generate a transmission signal. A signal transmitting means (13) transmits the transmission signal via a transmission path of a transmission interface type. A signal receiving means (21) receives the transmission signal. A signal restoring means (22) assembles the division signals in accordance with the assurance information and restores the multiplex signal.
(FR) Selon l'invention, on maintient la continuité de signaux multiplexés par répartition en fréquence et on restaure un signal d'origine, multiplexé, à grande capacité, afin d'effectuer une transmission grande capacité idéale. Des moyens diviseurs (11) de signal divisent un signal multiplexé et produisent plusieurs signaux de division du type pour interface de transmission de signaux de transport synchrones ou de module de transport synchrone. Des moyens d'ajout (12) d'informations d'assurance ajoutent de telles informations, lesquelles assurent la continuité entre les signaux de division pour produire un signal de transmission. Des moyens émetteurs (13) de signal émettent le signal de transmission, par l'intermédiaire d'un trajet de transmission du type interface de transmission. Des moyens récepteurs (21) de signal reçoivent le signal de transmission, et des moyens de restauration (22) de signal assemblent les signaux de division en fonction des informations d'assurance et restaurent le signal multiplexé.
