Izibani zethrafikhi zelanga zisebenza ngamaphaneli elanga, ashesha ukufakwa futhi kulula ukuwahambisa. Zisebenza ezindaweni ezisanda kwakhiwa ezinendawo enkulu yokuhamba kwethrafikhi kanye nesidingo esiphuthumayo somyalo wesignali entsha yethrafikhi, futhi zingahlangabezana nezidingo zokuphazamiseka kukagesi okuphuthumayo, ukuvinjelwa kukagesi kanye nezinye izimo eziphuthumayo. Okulandelayo kuzochaza isimiso sokusebenza kwezibani zethrafikhi zelanga.
Iphaneli yelanga ikhiqiza amandla kagesi ngokukhanya kwelanga, futhi ibhethri lishajwa yisilawuli. Isilawuli sinemisebenzi yokuxhumana okulwa nokubuya emuva, ukushaja okulwa nokubuya emuva, ukushaja okulwa nokuphuma ngokweqile, ukushaja ngokweqile, ukuvikela ukugcwala ngokweqile kanye nokuvikela okuzenzakalelayo kwe-short-circuit, futhi sinezici zokuhlonza ngokuzenzakalelayo imini nobusuku, ukutholwa kwamandla kagesi okuzenzakalelayo, ukuvikelwa kwebhethri okuzenzakalelayo, ukufakwa okulula, ukungangcoliswa, njll. Ibhethri likhipha i-annunciator, i-transmitter, i-receiver kanye nesibani sesignali ngesilawuli.
Ngemva kokuthi imodi esethiwe ye-annunciator isilungisiwe, isignali ekhiqizwe ithunyelwa kumthumeli. Isignali engenantambo ekhiqizwe ngumthumeli idluliselwa ngezikhathi ezithile. Ubuningi bokudlulisa kanye nokuqina kwayo kuhambisana nemithethonqubo efanele ye-National Radio Regulatory Commission, futhi ngeke kuphazamise amadivayisi anezintambo kanye nomsakazo azungeze indawo yokusetshenziswa. Ngesikhathi esifanayo, kuqinisekisa ukuthi isignali edlulisiwe inekhono elinamandla lokumelana nokuphazamiseka kwamasimu anamandla kazibuthe (imigqa yokudlulisa enamandla aphezulu, izinhlansi zezimoto). Ngemva kokwamukela isignali yokudlulisa engenantambo, umamukeli ulawula umthombo wokukhanya kwesibani sesignali ukuze aqaphele ukuthi izibani ezibomvu, eziphuzi neziluhlaza zisebenza ngokwemodi esethiwe. Uma isignali yokudlulisa engenantambo ingavamile, umsebenzi wokukhanyisa ophuzi ungabonakala.
Imodi yokudlulisa engenantambo iyasetshenziswa. Ezibanini ezine zesignali endaweni ngayinye yokuhlangana, i-annunciator kanye ne-transmitter kuphela okudingeka zisethwe endaweni yokukhanya yesibani esisodwa sesignali. Lapho i-annunciator yesibani esisodwa sesignali ithumela isignali engenantambo, abamukeli ezibanini ezine zesignali endaweni yokuhlangana bangathola isignali futhi benze izinguquko ezifanayo ngokwemodi esethiwe. Ngakho-ke, asikho isidingo sokubeka izintambo phakathi kwezibani zokukhanya.
