2019 Wapamwamba kwambiri Rs232 mpaka Rs485 - Co-Directional 64K Converter JHA-CE1tV1 - JHA

Co-Directional 64K-V.35 ConverterJHA-CE1tV1

Mwachidule

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". Mwa kusintha kusintha kwa polarity ya block yoyandikana, ma signature a binary amasintha ma sign atatu. Pagulu lililonse lachisanu ndi chitatu linawononga chipika cha polarity alternating, motero kufalitsa chizindikiro cha 8KHz. Potengera zomwe zili pamwambapa, chizindikiro cha G.703 chogwirizana ndi 64Kbps chitha kutumiza chizindikiro chanthawi ya 64KHz ndi 8KHz ndi 64KHz ndi chizindikiro cha data cha 64Kbit/s mbali imodzi yokhala ndi mzere wokhazikika.
64k-V.35 / V.24 mawonekedwe Converter amapereka ITU-T co-64K G.703 muyezo E1 mawonekedwe ndi muyezo V.35 kutembenuka mawonekedwe pakati pa wosanjikiza thupi / V.24. Network kuti apereke kulumikizana kotetezeka pakati pa zida zamitundu yosiyanasiyana, kulumikizana kopanda msoko. Chigawo cha Equipment E1 chimagwiranso ntchito pazida zotumizira zomwe zilipo, komanso kufunikira kotumiza deta kupita ku V35 / V24 kokha kutumizidwa pamwambowu, mawonekedwe a mawonekedwe a data ndi DCE, okhala ndi DTE kapena DCE polumikizira.
