Le ntambo yedatha yenziwe ngezinto ezisezingeni eliphezulu, eziqinile futhi ezihlala isikhathi eside. Futhi kulula ukuyifaka, ifanele izinhlobo ezihlukahlukene zemishini.Intambo ngayinye yekhebula eliyisicaba ihlolwe ngokuqinile ukuze imelane nokuphazanyiswa kwesignali kanye nokuvikela amagagasi kagesi ukuze kuqinisekiswe ukudluliswa kwedatha okuzinzile.

Le ntambo yedatha yenziwe ngezinto ezivikela izilwane ezifuywayo kanye nocingo lwethusi olunamekwe ngothayela oluyisicaba, olucindezelwa ndawonye ngomugqa wokukhiqiza wezinto ezizenzakalelayo. Inezinzuzo zokuqina okuthambile, okuncane kanye nevolumu encane.
