Abstract

En prosess for transmisjon av hjelpeinformasjoner på en bidireksjonell forbindelse for transmisjon av numeriske HDLC-data under dannelse av en primær transraisjonskanal for et numerisk opprinnelsessignal mellom et lokalpunkt og et fjernt punkt, en forbindelse på hvilken det avsendes minst en suksessjon av signaler i henhold til HDLC-protokollen og der de numeriske data transmitteres mellom to eller flere suksessive opprinnelsessignaler og et svarsignal eller en følge av signaler trans- mitteres på primærkanalen l fravær av transmisjon av numeriske data, omfatter, l det minste på det lokale og/eller fjerne punkt, med henblikk på å danne en sekundær transmisjonskanal for hjelpeinformasjoner, - å transkode minst et av opprinnelsessignalene ut fra de nevnte hjelpeinformasjoner som skal transmitteres for å danne minst et transkodet signal, - å transmittere, mot det fjerne punkt og/eller lokale punkt, på forbindelsen, det transkodede signal og de numeriske data, for å .danne et transkodet numerisk signal, og på det fjerne og/eller lokale punkt, - å dekode det transkodede signal for å restituere og å tolke hjelpeinformasjonen, inverst å transkode det transkodede signal for å rekonstituere opprlnnelsessignalet, og å transmittere det rekonstltuerte opprinnelsessignal og de numeriske data for å rekonstituere det numeriske opprinnelsessignal mot en anvendelse på det lokale eller fjerne punkt, noe som tillater på den ene side å sikre transmisjon av de numeriske data i transparens mellom det lokale punkt og det fjerne punkt eller omvendt, og, på den annen side, transmisjon og interpretasjon av hjelpeinforma- sjonene mellom det lokale punkt og det fjerne punkt, eller omvendt, på sekundærkanalen.A process for transmitting auxiliary information on a bidirectional connection for transmitting numerical HDLC data to form a primary transcription channel for a numeric origin signal between a local point and a distant point, a connection on which at least one successor of signals according to HDLC is transmitted The protocol and where the numeric data is transmitted between two or more successive origin signals and a response signal or a sequence of signals transmitted on the primary channel in the absence of transmission of numerical data comprises, at least at the local and / or distant point, with to form a secondary transmission channel for auxiliary information, - to transcode at least one of the origin signals from said auxiliary information to be transmitted to form at least one transcoded signal, - to transmit, towards the distant point and / or local point, on the connection, the transcoded signal and the numeric data, to form a transcoded numeric signal, and at the remote and / or local point, - to decode the transcoded signal to recover and interpret the auxiliary information, inversely to transcode the transcoded signal to reconstitute the origin signal, and to transmit the reconstructed origin signal and the numeric data to reconstitute the numeric origin signal against an application to the local or remote point, which allows, on the one hand, to ensure transmission of the numerical data in transparency between the local point and the distant point or vice versa, and, on the other hand, transmission and interpretation of the auxiliary information between the local point and the distant point, or vice versa, on the secondary channel.
