Uhlolojikelele Lesi siguquli esibonakalayo sisekelwe ku-FPGA, sisebenzisa ubuchwepheshe bokuphindaphinda kokuqondisa okubuyela emuva ukuze kuhlanganiswe amasekhethi amaningi e-E1 ukuze kudluliselwe idatha ye-Ethernet ye-100BASE-TX. Ingakwazi ukubona isiteshi esingu-1-8E1 ukuze iguqule phakathi kwe-Ethernet optical interface. Le divayisi ingadlulisela indawo yesignali ye-transceiver ukuze ikhombe ku-Ethernet optical interface ukuze yenze amashaneli e-E1 axhumeke nge-Ethernet optical interface. Ihluke ngebhuloho lenethiwekhi elikude elivamile, lolu cingo lungasekela ukucushwa kwesiteshi se-1-8Channel E1, lukwazi ukubona ngokuzenzakalelayo inombolo ye-E1 bese lukhetha i-E1 etholakalayo. Ivumela umehluko wesikhathi sokulibaziseka wokudlulisa imigqa ye-E1. ukulibaziseka umehluko. Isithombe Somkhiqizo 19inch 1U Uhlobo Izici Ezisekelwe kubunikazi bobunikazi be-IC Ukuze ufinyelele ukudluliswa kwedatha ye-Ethernet esobala kumasekhethi angu-1-8E1 Ingakwazi ukubona ukusetha kabusha idivayisi ye-Ethernet Interface yasendaweni nekude yi-100BASE-FX, isekela iphrothokholi ye-VLAN I-Inter-set dynamic Ethernet MAC ikheli ( 4,096) ngomsebenzi wokuhlunga uhlaka lwedatha yendawo Izinga lemigqa Yesiteshi Esisodwa ngu-1984Kbit/s, 4Channel Bandwidth kufika ku-7936Kbit/s Sekela yonke isethi ye-alamu ye-Ethernet Work Mode CRC ingasethwa ukuze ihlukanise izintambo zokudlulisela zekhwalithi embi futhi kunqanyulwe indlela eyodwa.
