OEM/ODM China Protocol Gateway - Co-Directional 64K-FE Converter JHA-CE1tF1 – JHA

Kakaretso

Khokahano ea G.703 (Co-Directional G.703) e arola potoloho ea 64Kbps ka linako tse 4, e sebelisa "0101" e emela "0", "1100" e emela "1". Ka ho fapanyetsana polarity ea phetoho ea block e haufi, matšoao a binary a fetola matšoao a mekhahlelo e meraro. Sehlopheng se seng le se seng sa bo8 se sentse boloko ba polarity e fapanyetsanang, kahoo ho fetisa lets'oao la nako la 8KHz. Ka likhoutu tse kaholimo, lets'oao la G.703 la 64Kbps le ka fihlella ho fetisa lets'oao la nako la 64KHz le 8KHz le 64KHz le lets'oao la data la 64Kbit/s ka nqa e ts'oanang ka mohala o leka-lekaneng.
Sesebelisoa sena sa ho fetola sebopeho se fana ka sebopeho se le seng sa G.703 le sebopeho se le seng sa Ethernet ho finyella phetiso ea data ea 10/100Base-T Ethernet ho mocha oa G.703. Ke ts'ebetso e phahameng, borokho ba ho ithuta ba Ethernet. Sesebelisoa sena ke sesebelisoa sa katoloso sa Ethernet, se sebelisang marang-rang (PDH/SDH/Microwave) se fanang ka mocha oa G.703 ho finyella Ethernet ea sebaka le e hōle e hokahanyang le li-interface tsa serial ka theko e tlaase. Sesebelisoa se na le ts'ebetso ea tlhahlobo ea li-loop tsa inter-set ho thusa ho qala projeke le tlhokomelo ea letsatsi le letsatsi.

Likaroloana

• E ipapisitse le IC ea boinotšing
• E ka Lemoha phetiso ea data ea Ethernet ho potoloho e le 'ngoe ea Co-directional G.703
• Inter-set dynamic Ethernet MAC address (4,096) e nang le filtara ea data ea lehae
• Sesebelisoa sa lehae se ka laola sesebelisoa se hole
• Eba le ts'ebetso ea G.703 loop back check, 'me u bontše ho LED
• E ka khetholla lebaka la ho lahleheloa ke lets'oao la Co-directional G.703 ke hore sesebelisoa se hole sa tima kapa mohala oa G.703 o robehile.
• Sehokelo sa Ethernet se tšehetsa 10M/100M, halofo / e felletseng ea duplex e ikamahanyang le maemo, e tšehetsa VLAN
• Sehokelo sa Ethernet se ts'ehetsa AUTO-MDIX (mohala o tšetsoeng le mohala o hokahaneng ka kotloloho o ikamahanyang le maemo);
• Fana ka mefuta ea oache ea 2: Co-Directional G.703 master clock le G.703 line clock;
• Sesebelisoa sa lehae se ka qobella sekhahla sa sesebelisoa se hole hore se se latele (ha sesebelisoa se sa hlophisoa, seo ha se sebetse)
• Eba le tse tharo tsa Loop Back Mode: G.703 interface Loop Back (ANA),Ethernet interface Loop Back(DIG),Laela sehokelo sa Ethernet se hole Loop Back(REM)
• Tšehetsa ho ikamahanya le maemo 120 Ohm ho leka-lekana;
