2019 Isiguquli Sekhwalithi Enhle Ye-Serial To Ethernet - I-Frame E1-V.35 Isiguquli se-JHA-CE1fV1 - JHA

Isiguquli esibonakalayo se-E1-V.35 esizimeleI-JHA-CE1fV1

Uhlolojikelele

Lesi siguquli se-interface sinikeza isixhumi esibonakalayo esisodwa se-E1 kanye nesixhumi esibonakalayo esisodwa se-V.35 ukuze kuzuzwe isixhumi esibonakalayo se-E1 esinohlaka sidluliselwe kusixhumi esibonakalayo se-V.35. Izinga lesiteshi sedatha ngu-2.048Mbps. Idivayisi inomsebenzi wokuhlola i-inter-set loop ukusiza ukuqaliswa kwephrojekthi nokugcinwa kwansuku zonke.

Isithombe Somkhiqizo

Uhlobo Oluncane

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• Yiba nesikhombi lapho idivayisi icishiwe noma ulayini we-E1 uphukile noma ulahlekelwa isignali;
• Idivayisi yasendaweni ingaphoqa isilinganiso sedivayisi esikude siyilandele (ivumelekile uma ifreyimu)
• I-Hardware ibona noma iyiphi ye-31 ye-slot yesikhathi nganoma yisiphi isikhathi ngokuzikhethela (ivumelekile uma ifreyimu)
• Nikeza ama-impedances angu-2: 75 Ohm ukungalingani kanye nebhalansi engu-120 Ohm;
• Ngemuva kokuhlolwa okuqinile kanye nohlelo lokuqinisekisa olusebenzayo, thobela ngokuphelele umthetho olandelwayo ITU-T V.35, G.703, G.704
• Iba ne-Loop Back Mode emithathu: i-E1 interface Loop Back (ANA),I-V.35 interface Loop Back(DIG),Yala i-V.35 interface Loop Back(REM)
• Yiba nomsebenzi wokuhlola wekhodi okungahleliwe mbumbulu, ulayini ovulwe kalula, ungasetshenziswa njengesihloli se-2M BER
• I-interface ye-V.35 isekela ipulaki eshisayo, isekela uxhumano lwedivayisi ye-DTE noma ye-DCE
• Nikeza izinhlobo zamawashi ezi-3: Iwashi langaphakathi, iwashi langaphandle, iwashi lomugqa we-E1;
• I-AC 220V, DC-48V, DC+24V, DC Power and Polarity-Free
