Abstract

Det er oppfinnelsens oppgave å fremskaffe en fremgangs- måte og en anordning som med en minimert båndbredde tillater å øke rekkevidden til transmisjonsbanen mellom ISDN-abonnentlinjens funksjonsenheter i forhold til et ISDN-grensesnitt. Ifølge oppfinnelsen blir oppgaven løst ved en fremgangsmåte hvor (a) datasendingen på nettsiden og også på terminalsiden foregår slik at ISDN-spesifikt kodede data ved hjelp av en kodeomformer blir omformet til binærkodede data, (b) B-kanalenes an- kommende data blir klarstilt for Bl- og B2-kanaldata i like lange avsnitt i en lagringsanordning og deretter tilført overføringsmidlet og via dette formidlet til mottakersiden, idet dataene som kommer fra lagringsan- ordningen, blir undersøkt med hensyn til datalikhet og blir komprimert; (c) det fra D-kanalens ankommende data blir dannet blokker som blir ført til overføringsmidlet for formidling til mottakersiden, (d) den ISDN-spesi- fikke takt ved hjelp av et taktgjenvinningsmiddel på terminalsiden henholdsvis nettsiden blir gjenvunnet fra de overførte databiters tidsmessige rekkefølge, og (e) de mottatte databiter blir analysert, gjenkjente D- kanalblokker blir løst opp og direkte tilført en kode- omf ormer, og gjenkjente B-kanaldata blir dekomprimert og de binærkodede data omformet til ISDN-spesifikt kodede data.It is the object of the invention to provide a method and a device which, with a minimum bandwidth, allows to increase the range of the transmission path between the functional units of the ISDN subscriber line relative to an ISDN interface. According to the invention, the task is solved by a method in which (a) the data transmission on the website and also on the terminal side takes place so that ISDN-specifically encoded data is converted to binary-encoded data by means of a code converter, (b) the upcoming data of the B-channels is made clear for B1 and B2 channel data in equal lengths of a storage device and then fed to the transmission means and via this transmitted to the receiver side, the data coming from the storage device being examined for data similarity and being compressed; (c) blocks arriving from the D-channel are formed which are passed to the transmit means for transmission to the receiving side; and (e) the received data bits are analyzed, recognized D-channel blocks are dissolved and directly supplied to a code encompassing worms, and recognized B-channel data are decompressed and the binary-encoded data is converted to ISDN-specifically encoded data.
