2019 Ikhwalithi ephezulu Rs232 Kuya ku-Rs485 - I-Co-Directional 64K-FE Converter JHA-CE1tF1 - JHA

Uhlolojikelele

Isixhumi esibonakalayo se-G.703 (Co-Directional G.703) sihlukanisa umjikelezo ongu-64Kbps ube yizikhawu zamayunithi angu-4, sisebenzisa okuthi “0101” simele u-“0”, “1100” simele “1″. Ngokushintshanisa i-polarity yebhulokhi eseduze, amasignali kanambambili aguqula amasignali anamazinga amathathu. Kulelo nalelo qembu lesi-8 libhubhise ibhulokhi ye-polarity eshintshanayo, ngaleyo ndlela ukudlulisa isignali yesikhathi engu-8KHz. Ngombhalo wekhodi ongenhla, isignali ye-G.703 ye-co-directional 64Kbps ingafinyelela ukudlulisa isignali yesikhathi engu-64KHz no-8KHz kanye no-64KHz kanye nesignali yedatha engu-64Kbit/s ohlangothini olufanayo nolayini olinganiselayo.
Lesi siguquli esibonakalayo sinikeza isixhumi esibonakalayo se-G.703 esihlangene kanye nesixhumi esibonakalayo esisodwa se-Ethernet ukuze kuzuzwe ukudluliswa kwedatha ye-Ethernet engu-10/100Base-T esiteshini se-G.703. Iwukusebenza okuphezulu, ibhuloho le-Ethernet lokuzifundela. Le divayisi iyidivayisi enwetshiwe ye-Ethernet, isebenzisa inethiwekhi (i-PDH/SDH/Microwave) ehlinzeka ngesiteshi se-G.703 ukuze kufinyelelwe ekuxhumekeni kwe-Ethernet yasendaweni nesilawuli kude nezixhumi ezibonakalayo ze-serial ngezindleko eziphansi. Idivayisi inomsebenzi wokuhlola i-inter-set loop ukusiza ukuqaliswa kwephrojekthi nokugcinwa kwansuku zonke.

Isithombe Somkhiqizo

• Ingakwazi ukuhlukanisa isizathu se-Co-directional G.703 yokulahlekelwa isignali ukuthi idivayisi yesilawuli kude inqanyuliwe noma ulayini we-G.703 wesiqondisi uphukile uphukile
• I-Ethernet interface isekela i-10M/100M, isigamu/egcwele i-duplex eguquguqukayo, isekela i-VLAN
• Isixhumi esibonakalayo se-Ethernet sisekela i-AUTO-MDIX (umugqa onqanyuliwe kanye nomugqa oxhumeke oqondile ozivumelanisa nezimo);
• Nikeza izinhlobo zamawashi ezi-2: Iwashi eliyinhloko le-Co-Directional G.703 kanye newashi lomugqa we-G.703;
• Idivayisi yasendaweni ingaphoqa ukuthi izinga ledivayisi elikude liyilandele (uma idivayisi iyimodi engafakwanga uzimele, lokho akuvumelekile)
• Iba ne-Loop Back Mode emithathu: G.703 interface Loop Back (ANA),Isixhumi esibonakalayo se-Ethernet Loop Back(DIG),Yala isixhumi esibonakalayo se-Ethernet esikude Loop Back(REM)
• Sekela ibhalansi ekwazi ukuzivumelanisa nezimo engu-120 Ohm;
