Isandisi senethiwekhi iyisisetshenziswa esinganweba ngempumelelo ibanga lokudlulisa inethiwekhi.Umgomo uwukushintsha isignali yedijithali yenethiwekhi ibe isignali ye-analog ngocingo, ukupheya okusontekile, ulayini we-coaxial ukuze udluliselwe, bese wehlisa isignali ye-analog ibe isignali yedijithali yenethiwekhi ngakolunye uhlangothi.I-extender yenethiwekhi ingakwazi ukweqa umkhawulo webanga lokudlulisela le-Ethernet elivamile phakathi kwamamitha angu-100, futhi inganweba isignali yenethiwekhi ibe amamitha angu-350 noma ngaphezulu.Yelula umkhawulo webanga lokudlulisa inethiwekhi ukusuka kumamitha ayi-100 ukuya kumakhulu amamitha noma ngaphezulu, futhi ingabona kalula ukuxhumana phakathi kwamahabhu, amaswishi, amaseva, amatheminali namatheminali akude.
