Guhuza Icyerekezo 64K-V.35 GuhinduraJHA-CE1tV1

Incamake

Imigaragarire ya G.703 (Co-Directional G.703) igabanya uruziga rwa 64Kbps mu bice 4, ikoresha “0101” igereranya “0”, “1100” igereranya “1 ″. Muguhinduranya impinduka polarite yumurongo wegeranye, ibimenyetso bibiri bihindura ibimenyetso byinzego eshatu. Muri buri tsinda rya 8 ryasenye guhagarika guhinduranya polarite, kugirango wohereze ibimenyetso byigihe 8KHz. Ukoresheje code yavuzwe haruguru, ikimenyetso cya G.703 icyerekezo 64Kbps gishobora kugera ku kohereza ibimenyetso byigihe cya 64KHz na 8KHz na 64KHz hamwe namakuru yamakuru ya 64Kbit / s mu cyerekezo kimwe n'umurongo uringaniye.
64k-V.35 / V.24 Ihinduramiterere itanga ITU-T co-64K G.703 isanzwe ya E1 hamwe na interineti isanzwe ya V.35 ihinduka hagati yumubiri / V.24. Umuyoboro kugirango utange itumanaho ryizewe hagati yibikoresho byintera zitandukanye, ihuza ridafite. Ibikoresho E1 igice cyerekeranye nibikoresho byoherejwe biboneka, kandi bikenewe kohereza amakuru kuri hamwe na V35 / V24 yohereza ibicuruzwa gusa, uburyo bwimikorere yamakuru ni DCE, hamwe nibikoresho bya DTE cyangwa DCE.
