Setiap frame pada layer baseband bisa berupa satu diantara tiga jenis mekanisme hopping yaitu one-slot,

three-slot, or five-slot .

Setiap slot mempunyai waktu 625 mikrodetik, sedangkan hoping membutuhkan waktu 259 mikrodetik, jadi

Waktu satu slot = 625 259 = 366 mikrodetik

Waktu tiga slot = 3 x 625 - 259 = 1616 mikrodetik

Waktu lima slot = 5 x 625 - 259 = 2866 mikrodetik
