01 Co-Directional 64K Converter JHA-CE1tV1
Co-Directional 64K-V.35 Converter JHA-CE1tV1 Chidule Mawonekedwe a G.703 (Co-Directional G.703) amagawaniza kuzungulira kwa 64Kbps mu magawo anayi a mayunitsi, amagwiritsa ntchito "0101" kuyimira "0", "1100" kuyimira "1 ". Posintha masinthidwe a polarity wa block yoyandikana, ma siginecha a binary amasintha ma siginali atatu. Gulu lachisanu ndi chitatu linawononga chipika cha polarity alternating, motero kutumiza chizindikiro cha nthawi ya 8KHz Polemba zomwe zili pamwambapa, chizindikiro cha G.703 cha 64Kbps chikhoza kutumiza chizindikiro cha nthawi ya 64KHz ndi 8KHz ndi 64KHz ndi chizindikiro cha data cha 64Kbit/s. malangizo omwewo ndi mzere woyenerera 64k-V.35 / V.24 chosinthira mawonekedwe ITU-T co-64K G.703 mawonekedwe amtundu wa E1 ndi mawonekedwe osinthika a V.35 pakati pa wosanjikiza wakuthupi / V.24 Network kuti apereke mauthenga otetezeka pakati pa zipangizo zosiyana siyana, gawo lopanda malire la E1 likugwiritsidwa ntchito pofalitsa zida zomwe zilipo, komanso kufunikira kotumiza deta kupita ku V35 / V24 yokha yotumizidwa pamwambowu, mawonekedwe amtundu wa data ndi DCE, yokhala ndi DTE kapena DCE yolumikizira. Zina mwa Mtundu Wachithunzi Chaching'ono Chopangidwa ndi IC; Perekani mitundu ya wotchi ya 2: Co-Directional G.703 master clock ndi G.703 line clock; Khalani ndi njira ziwiri za Loop Back: G.703 mawonekedwe Loop Back , V.35 mawonekedwe Loop Back; Khalani ndi pseudo mwachisawawa kuyesa code ntchito, yosavuta kukhazikitsa; Thandizani 120 Ohm bwino; V.35 mawonekedwe amathandiza otentha pulagi; Perekani mitundu ya wotchi 3: Wotchi yamkati, wotchi yakunja, wotchi ya E1; AC 220V, DC-48V, DC+24V, DC Mphamvu ndi Polarity-Free.
