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.

 Ubwoko bwa Mini

Ibiranga

• Bishingiye ku kwikorera uburenganzira bwa IC
• Irashobora Kumenyekanisha amakuru ya Ethernet muburyo bumwe bwa G.703
• Inter-set dinamike ya Ethernet MAC aderesi (4,096) hamwe namakuru yimbere yo gushungura
• Igikoresho cyaho gishobora kuyobora igikoresho cya kure
• Gira imikorere ya G.703 gusubiramo inyuma, hanyuma werekane kuri LED
• Irashobora gutandukanya impamvu ya Co-icyerekezo G.703 gutakaza ibimenyetso ni uko igikoresho cya kure amashanyarazi-kizimya cyangwa icyerekezo G.703 cyacitse
• Imigaragarire ya Ethernet ishyigikira 10M / 100M, igice / cyuzuye duplex auto-adaptable, ishyigikira VLAN
• Imigaragarire ya Ethernet ishyigikira AUTO-MDIX (umurongo wambukiranya kandi umurongo uhujwe neza-wihuza);
• Tanga ubwoko 2 bwamasaha: Co-Directional G.703 isaha nini na G.703 isaha;
• Igikoresho cyaho kirashobora guhatira igipimo cyibikoresho bya kure kugikurikiza (mugihe igikoresho kidafite uburyo, ibyo bikaba bitemewe)
• Kugira uburyo butatu bwo gusubira inyuma: G.703 Imigaragarire Yinyuma (ANA)、Imigaragarire ya Ethernet Yisubire inyuma (DIG)、Tegeka interineti ya kure ya Ethernet Loop Back (REM)
• Shyigikira kwimenyekanisha 120 Ohm iringaniye;
