Definitions

  • the subject matter of the application relates to a method for secure dynamic bandwidth allocation in multichannel transmission systems, in particular time division multiplex or frequency division multiplex transmission systems, in which digital information is transmitted in frames.
  • Future multi-channel transmission systems such as. B. SDSL (Symmetry Digital Subscriber Line) subscriber connections in telecommunications switching systems will adapt flexibly to the transmission channel and also dynamically adapt to
  • the object of the application is based on the problem of specifying a method for a multichannel transmission system in which dynamic bandwidth allocation is ensured even when bit errors occur during transmission. ⁇ > tt h- 1 P 1 Ji O t ⁇ o Cn o Cn
  • the frame shown in Fig. 1 is characterized by a constant duration of 6 ms.
  • the payload is divided into 4 groups of 12 variable user data blocks and supports (0 ... 7) so-called Z channels with 8 kBit / s each and (3 ... 36) B channels with 64 kBit / s each.
  • the "Bandwidth Allocation Field” (bits 1 to 32) shows the status of the channel assignment. All B channels used for voice services (ISDN BRA (Basic Rate Access) or POTS (Piain Old England Service)) are identified by a 1 value at the corresponding bit position. All B channels marked with an O value are made available for the data pipe until the maximum number of channels supported by the SDSL system is reached.
  • the remaining 8 bits are reserved for further tasks.
  • an "embedded signaling channel” is thus set up, via which messages and data exchange between line termination and network termination are processed.
  • the data pipe can be subdivided, for example to support ATM traffic in addition to Ethernet-based traffic or to distribute the data traffic to different providers.
  • the necessary information for bandwidth allocation can be transmitted jointly for the entire frame or individually within the various user data blocks.

Abstract

L'invention vise à mettre en oeuvre une attribution de bande dynamique sécurisée dans un système de transmission multicanal tel qu'un système de transmission multiplexé en temps ou en fréquence, en particulier dans un système de transmission SDSL (ligne numérique à paire symétrique) dans lequel des informations numériques sont transmises par trames. A cet effet, l'information complète d'attribution de bande est transmise de manière sécurisée à l'intérieur de chaque trame. Par ailleurs, il est possible de déterminer de manière univoque, pour chaque trame, quel canal est attribué à quel service. En cas de modification de l'attribution des canaux, les informations prégnantes sont disponibles suffisamment tôt côté récepteur, de manière que l'attribution de bande modifiée peut être prise en compte dès réception de la trame suivante.
