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.
Ihinduramiterere rya interineti ritanga icyerekezo kimwe cya G.703 hamwe na interineti imwe ya Ethernet kugirango ugere kuri 10 / 100Base-T Ethernet yohereza amakuru kumuyoboro wa G.703. Nibikorwa bihanitse, kwiyigisha-Ethernet ikiraro. Iki gikoresho nigikoresho cyo kwagura Ethernet, ukoresheje umuyoboro (PDH / SDH / Microwave) utanga umuyoboro wa G.703 kugirango ugere kumurongo wa kure na kure wa Ethernet uhuza hamwe na seriyeri ku giciro gito. Igikoresho gifite inter-set loop test yo korohereza umushinga gutangiza no kubungabunga buri munsi.
