Abstract

En fremgangsmåte og utstyr for multipleksering av tale og datainformasjon inn på minimum en overfør- ingslinje av en første type i et koitununikasjons- system, idet den omtalte metode inneholder trinnene: dele overføringslinjen inn i en mengde med kanaler, komprimere og/eller dele taleinformasjonen inn i en eller flere strømmer, idet hver strøm sendes med en hastighet tilsvarende til overføringskapasiteten for en av de inndelte kanaler fra overføringslinjen, deling av datainformasjonen inn i en eller flere strømmer, idet hver strøm sendes med en hastighet tilsvarende til overføringskapasiteten for en av kanalene fra overføringslinjen, og dynamisk alloker- ing og fra-allokering av strømmene med tale og data- informasjon til kanalene fra omtalte overførings- linje avhengig av behov.A method and equipment for multiplexing speech and data information into at least one transmission line of a first type in a co-communication system, said method comprising the steps of: dividing the transmission line into a plurality of channels, compressing and / or dividing the voice information in one or more streams, each stream being transmitted at a rate corresponding to the transmission capacity of one of the divided channels from the transmission line, dividing the data information into one or more streams, each stream being transmitted at a rate corresponding to the transmission capacity of one of the channels from the transmission line, and dynamic allocation and sub-allocation of the streams with voice and data information to the channels from the said transmission line depending on need.
