Abstract

I sentralstyrte nettreserve-svitsje-systemer blir sentralene bare informert. av digitalsignalfordelere om mottagelsen. av AlS-signaler eller konstateringen av. mangler ved digitalsignelene, men ikke av. det øvrige linjeutstyr. Da digitalsignal-fordelerne ikke kan registrere hvor et. AlS-signal ble matet inn, blir like. meldinger etter omstendighetene gitt. flere ganger, uten at sentralene er. istand til å vite om det foreligger ett. eller flere feilsteder langs linjen.Det blir innfart et modifisert AlS-signal. som består av det kjente normerte. AlS-signal i form av et varig enersignal. og en merking. Denne består enten av med. lik avstand innføyede enkelte nuller med. en hyppighet på mindre enn IO-eller er. et tilleggssignal. Når digitalsignalfor-deleren (8) mottar et normert AlS-signal. eller registrerer en annen mangel, mater. den et modifisert AlS-signal inn i den. utgående linje (15). Bare de etterføl-gende digitalsignalfordelere (9,10,11,12). registrerer modifikasjonen og mater på. sin side et slikt videre og gir avkall på. en melding til en regional sentral (3,4).Nettstyringssentralen (1) svitsjer på grunn av meldingen fra digitalsignalfor-deleren (8) en reservelinje (16).Oppfinnelsen kommer til anvendelse i sentralstyrte nettreserve-svitsj e-systemer.
