Ukuthengiswa okushisayo kwe-E1 Converter - 8E1+4FE PDH Multiplexer JHA-CPE8F4 – JHA

8E1+4FE PDF MultiplexerJHA-CPE8F4

Uhlolojikelele

Le divayisi inikeza isixhumi esibonakalayo esingu-1-8*E1, isixhumi esibonakalayo esingu-1-4*10M/100M Ethernet (Isivinini socingo 100M) nesixhumi esibonakalayo esinwetshiwe esingu-2. 4* I-Ethernet interface iwukushintsha isikhombimsebenzisi, ingasekela i-VLAN. 2 isikhombikubona esinwebekayo singasetshenziswa njengesiteshi sokudlulisa se-RS232/RS485/RS422 idatha ye-asynchronous. Ivumelana nezimo kakhulu. Inomsebenzi we-alamu. Umsebenzi unokwethenjelwa, uzinzile, futhi ukusetshenziswa kwamandla aphansi, ukuhlanganiswa okuphezulu, usayizi omncane.

Isithombe Somkhiqizo

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• I-Modular wide dynamic optical detector
• I-Ethernet (Ijubane Lomugqa 100M) izinga lokuxhumanisa ngu-10M/100M, uhhafu/ogcwele i-duplex Auto-Nego
• I-E1 interface ithobelana ne-G.703, yamukela ukutholwa kwewashi ledijithali kanye nobuchwepheshe bokukhiya besigaba obushelelezi
• Isebenzisa ucingo olujwayelekile olu-2 (izibambo okungezona ezocingo) ezisethwe njengenombolo yocingo yocingo ye-oda lobunjiniyela(kuyakhetheka)
• Nikeza isixhumi esibonakalayo esinwetshiwe esi-2 singasetshenziswa njengesiteshi sokudlulisa se-RS232/RS485/RS422 idatha esynchronous
• Uma isignali yokubona yokulahlekelwa, ingathola ukuthi idivayisi eyirimothi ivaliwe noma i-fiber inqanyuliwe, futhi ibonisa i-alamu nge-LED.
• Idivayisi yasendaweni ingabuka isimo sokusebenza kwesilawuli kude
• Nikeza umyalo wesixhumi esibonakalayo esikude Loop Back, lula ukulungisa umugqa
• Ibanga likagesi lifika ku-2-120Km ngaphandle kokuphazamiseka
• I-AC 220V, DC-48V, DC24V ingakhethwa
• I-DC-48V/DC24V umsebenzi wokuthola i-polarity wokunikezwa kwamandla, I-Polarity-Free
