Title: Method of integrating the simultaneous transmission of data and speech in a local ring network.
IPC: H04L12/43
Filed: 1985-05-13
Abstract: Method of integrating the simultaneous transmission of data and speech in a local ring network. The method rests upon a variable number of channels for data and for speech travelling over a self-synchronised local ring network and allowing a considerable improvement in the efficiency of transmission. These channels are grouped into frames which travel continuously and simultaneously around the ring and can take only three necessary and sufficient states. The network is plesiochronous, each station having its own synchronism and the obligation to transmit each channel regularly. The performance is determined essentially by the pass band of the system which determines the number of channels obtained through a time division, given that the duration of transmission of the collection of channels is limited to 125 microseconds. The method according to the invention is particularly intended for local area ring networks which require the integrated transmission of data and telephone information.
