8E1-4FE ujongano lokuguqulelaJHA-CE8F4

(Ukwahlukaniswa okusengqiqweni)

Isishwankathelo

Isixhobo sisebenzisa itekhnoloji ye-reverse direction multiplexing ukudibanisa kwiisekethe ezininzi ze-E1 ukuhambisa idatha ye-Ethernet ye-4Channel 100BASE-TX. Iyakwazi ukuqonda ukuguqulwa phakathi kwe-1 ~ 8 itshaneli ye-E1 kunye ne-Ethernet ujongano olubonakalayo, ukwenza iziteshi ze-E1 ezidityaniswe ne-Ethernet interface optical. Ukusebenzisa i-GFP encapsulation, xhasa i-LCS (isikimu sokulungelelanisa umthamo) kunye neprotocol ye-LAPS.

Esi sixhobo sinokuxhasa ubumbeko lwetshaneli ye-1-8 yeChaneli E1, inokubona ngokuzenzekelayo inani le-E1 kwaye ukhethe i-E1 ekhoyo. Ivumela i-E1 imigca yokuhambisa ixesha, i-1channel/4channel/8channel Ethernet bandwidth is1984Kbit/s, 7936Kbit/s, 15872 Kbit/s.
Isixhobo sibonelela ngomsebenzi we-alamu. Umsebenzi unokwethenjelwa kwaye uphantsi kokusetyenziswa kwamandla, ukudibanisa okuphezulu, ubungakanani obuncinci. Inkxaso Ulawulo lweNethiwekhi , Umsebenzi oyintloko wenkqubo yolawulo lwenethiwekhi kukuzalisekisa uphando lwezixhobo zendawo kunye nezikude kunye nolawulo loqwalaselo olubandakanya ukubuza ubume be-alarm kumgca we-E1, isimo sokusebenza se-Ethernet, kunye nokulawulwa kwe-loopback njl.

Iimbonakalo

• Ukuhanjiswa okucacileyo kwedatha ye-Ethernet kwi-1 ukuya kwi-8 yeesekethe ze-E1;
• Inokuxhotyiswa nge-Ethernet emine yokutshintsha ujongano lombane ukuze umsebenzisi agcine iswitshi ye-Ethernet;
• I-Ethernet 10/100M, i-duplex epheleleyo / isiqingatha iguquguquka ngokupheleleyo, inkxaso yeprotocol yeVLAN;
• Ichweba ngalinye lixhasa inkxaso ye-Ethernet ye-AUTO-MDIX (ikhebula le-crossover kunye ne-straight-line adaptation);
• I-interface ye-Ethernet nayo i-optical interfaces yokuzikhethela ukuphumeza ukuhanjiswa kwedatha ye-Ethernet ngokudibanisa i-E1 kude;
• I-8-channel E1 imigca, umahluko omkhulu wokulibaziseka phakathi kwazo naziphi na ezimbini unokufikelela kwi-220ms; xa ukulibaziseka ukulibaziseka ngaphezu kwe-220ms, ukulibaziseka kuya kuvelisa i-alarm engafanelekanga, ngelixa ukuphazamiseka kwezoshishino;
• Uluhlu lwedilesi ye-Ethernet ye-MAC eyakhiwe ngamandla (4096), kunye nomsebenzi wokucoca isakhelo sedatha yendawo;
• I-interface ye-E1 ihambelana ne-ITU-T G.703, G.704 kunye ne-G.823, ayixhasi ukusetyenziswa kweendawo zokubonisa;
• Imowudi yexesha, ixesha elikhethiweyo lendawo kunye nokulandelela ixesha lomgca we-E1, umthombo wexesha lomgca we-E1 unokutshintshwa ngokuzenzekelayo ngokomgangatho wesignali. Njengenkqubo yomthombo wexesha le-E1 kwiNdlela yokuqala ye-E1, xa ukusilela kwe-E1 yokuqala (isilumkiso esinzulu LOS/AIS/LOF/CRC4 okanye isiginali yokuvelisa iluphu) kunye nomendo wesibini u-E1 usebenza ngokufanelekileyo, inkqubo iya kutshintshela ngokuzenzekelayo kumzila. Indlela yesibini E1; ukupheliswa kwesiphoso, inkqubo emva koko ibuyele ngokuzenzekelayo kwindlela yokuqala ye-E1;
• Ukuthotyelwa kweprotocol ye-ITU-T esemgangathweni, isiphakamiso se-GFP-F ye-encapsulation G.7041, i-VCAT yokudibanisa i-virtual kunye ne-LCAS Link Capacity Adjustment iingcebiso G.7042, i-Ethernet mapping ukuya kwi-nxE1 ncomo G.7043, i-Ethernet ukuya kwi-E1 enye ingcebiso yemephu G. 8040;
• Xa i-bandwidth yokudlulisa inyuka, ayiyi kulimaza idatha ye-Ethernet; Ukuhanjiswa kwe-bandwidth kuncitshiswe ngokwenziwa, kunokuqondwa ngaphandle kokonakalisa inethiwekhi yedatha ye-Ethernet;
