2019 Ikhwalithi ephezulu ye-Rs232 ukuya ku-Rs485 - 4E1-4FE Isiguquli Sesixhumi esibonakalayo JHA-CE4F4 (I-Logical lsolation) - JHA

Uhlolojikelele

Lesi siguquli esisebenzisanayo sisekelwe ku-FPGA, sisebenzisa ubuchwepheshe bokuphindaphinda kokuqondisa okubuyela emuva ukuze kuhlanganiswe amasekhethi amaningi e-E1 ukuze kudluliselwe idatha ye-Ethernet ye-4Channel 100BASE-TX. Ingakwazi ukubona ishaneli engu-1~4 E1 ukuze iguqule phakathi kwesixhumi esibonakalayo se-Ethernet. Le divayisi ingadlulisela indawo yesignali ye-transceiver ukuze ikhombe ku-Ethernet optical interface ukuze yenze amashaneli e-E1 axhumeke nge-Ethernet optical interface. Ngokungafani nebhuloho lenethiwekhi elikude elivamile, lolu cingo lungasekela ukumiswa kwesiteshi se-1-4Channel E1, lukwazi ukubona ngokuzenzakalelayo inombolo ye-E1 bese lukhetha i-E1 etholakalayo. Ivumela umehluko wesikhathi sokulibaziseka wokudlulisa imigqa ye-E1.

• Ngokusekelwe ku-IC ye-self-copyright
• Ukuze kuzuzwe Ethernet idatha transparent transparent kumasekethe 1-4E1
• Ingabona ukusetha kabusha idivayisi yendawo nesilawuli kude
• I-Ethernet Interface yi-100BASE-FX, isekela iphrothokholi ye-VLAN
• Ikheli le-Inter-set eliguqukayo le-Ethernet MAC (4,096) elinomsebenzi wokuhlunga uhlaka lwedatha yendawo
• Izinga lemigqa yesiteshi esisodwa ngu-1984Kbit/s, 4Channel Bandwidth ifika ku-7936Kbit/s
• Isixhumi esibonakalayo se-Channel 10M/100M Ethernet singahlukanisa ukuze kubonakale ukuxhumana ngokuzimela
• I-Ethernet interface isekela i-10M/100M, isigamu/egcwele i-duplex ekwazi ukuzivumelanisa nezimo kanye ne-AUTO-MDIX (umugqa oweqa futhi umugqa oqondile ozivumelanisa nezimo)
• Umkhawulo we-alamu ozenzakalelayo we-CRC ungasethwa ukuze uhlukanise imigqa yokudlulisela yekhwalithi embi futhi kunqanyulwe indlela eyodwa. Uma izinga lephutha lesifunda segatsha le-2M lidlula umkhawulo, ukunqamula leli cala kolunye uhlangothi akuthinteki; okusho ukuthi, zombili i-Ethernet directiontransmission ingaba i-asymmetric
• Vumela umehluko wesikhathi sokulibaziseka we-4-Channel E1 ongu-100ms. Uma imajini idlula ibanga elivunyelwe, isistimu ingama ngokuzenzakalelayo ku-E1 ukuthi ukubambezeleka kukhulu kakhulu ukuthumela idatha
• I-E1 interface ihambisana ne-ITU-T G.703, G.704 ne-G.823, ayisekeli ukusetshenziswa kwesiginali yesikhathi sesikhathi
• Imojula yesixhumi esibonakalayo ye-E1 enesekhethi yokutakula iwashi eliphakathi-set kanye nesifunda sekhodi ye-HDB3
• Sekela i-hot-plug yesiteshi se-E1 kudivayisi, futhi ithola ngokuzenzakalelayo isiteshi se-E1 esisebenzayo futhi ngeke iphazamise ukudluliswa kwedatha
• Ingakwazi ukusekela ukucushwa kwesiteshi se-1-4Channel E1, ingathola ngokuzenzakalelayo inombolo ye-E1 bese ikhetha i-E1 etholakalayo;
