A.4 nomoro ea cheke ea CRC ea linomoro tse 16
Moamoheli kapa komporo ea lekhoba e ka ahloloa ka khoutu ea ho hlahloba hore na tlhahisoleseling e fumanoeng e nepahetse kapa che. Ho sitisoa ke lerata la elektroniki kapa lintlha tse ling ho ka baka liphoso nakong ea phetiso ea tlhahisoleseling.
Khoutu ea cheke ea CRC ea linomoro tse 16 e baloa ke moamoheli, e teng qetellong ea foreimi ea tlhaiso-leseling e fetisang. Lekhoba le bala hape lintlha tse amohetsoeng tsa CRC ebe le bapisa haeba CRC e baloang e tsamaisana le CRC e amohetsoeng, haeba ho se joalo, ho na le phoso. Ke li-data tse 8 feela tse sebelisoang nakong ea lipalo tsa CRC, li-bits tsa ho qala le li-stop bits ha li amehe palong. Mokhoa oa ho bala oa khoutu ea tlhahlobo ea CRC o boletsoe ka tsela e latelang:
