Co-Directional 64K-FE Converter JHA-CE1tF1

Kakaretso

Khokahano ea G.703 (Co-Directional G.703) e arola potoloho ea 64Kbps ka linako tse 4 tsa li-unit, e sebelisa "0101" e emela "0", "1100" e emela "1".Ka ho fapanyetsana polarity ea phetoho ea sebaka se haufi, matšoao a binary a fetola matšoao a mararo.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 ka holimo, lets'oao la G.703 la co-directional 64Kbps le ka khona ho fetisetsa 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 sehokelo se le seng sa Ethernet ho fihlella phetiso ea data ea 10/100Base-T Ethernet mocheng 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;
