Ukwehluleka unomphela:
Ukuze uthole amaphutha ahlala njalo, iluphu ingasetshenziswa ekugcineni, kanti enye ekugcineni ingaboniswa kusuka kushintsho noma isigaba esahluliwe ngesigaba kanye nesendlalelo ngesendlalelo nge-analyzer yokudlulisela.

1. Ama-alamu okudlulisa avela ngamabili. Isibonelo, uma i-RJA (i-alamu ekude) ivela ohlangothini luka-A, khona-ke uhlangothi lwe-B lungase lube i-LFA (uhlaka oluphuma ku-alamu yokuvumelanisa) noma i-AIS (thola i-alamu), futhi ngezinye izikhathi zombili izinhlobo zama-alamu zikhona; enye i-alamu ye-LS (Signal loss).

Esinye sezizathu zokwehluleka:Kunenkinga ngesiginali ethunyelwe i-A-side DM, okungukuthi, isignali engu-2Mb/s ethunyelwe iphutha noma ukuphazamiseka.
*Indlela yokwahlulela: buyela emuva ekugcineni A nge-DDF yesiphetho A. Uma kukhona i-alamu ye-LS noma ye-AIS ekugcineni A, kuyiphutha.
*Isixazululo: Cela abasebenzi abasegumbini lekhompiyutha ukuthi baqale kabusha noma balayishe kabusha imojula yokudlulisa ukuze basule i-alamu.

Isizathu sesibili: Inkinga yenzeka eqenjini le-oda eliphansi ukusuka ekugcineni kuka-A ukuya ekugcineni kuka-B endaweni ethile, okubangela iphutha lesiginali engu-2Mb/s noma ukuphazamiseka.
*Indlela yokwahlulela: Uma kunenkinga ukusuka ku-A ukuya ku-B phakathi kwamaqembu ane-oda eliphansi kuzo zombili iziphetho zika-A no-B, i-alamu ye-AIS noma ye-LFA izoboniswa ekugcineni kuka-B. Uma isignali esuka eqenjini le-oda eliphansi ukuya ku-DM ekugcineni kuka-B iphazamiseka, isiphetho sika-B sibonisa i-alamu ye-LS.
*Isixazululo: Ngokwezithiyo ezitholiwe, noma wenze kabusha ikhanda ku-DDF, noma shintsha i-U-Link, noma shintsha idiski yomshini ukuze ufeze injongo yokubuyisela isekethe.

2. Ama-alamu okudlulisa awaveli ngamabili. Isibonelo, ama-alamu e-AIS kanye ne-RJA avela ngesikhathi esifanayo ekugcineni A, noma ama-alamu e-LFA avela ngesikhathi esifanayo, kodwa ayikho i-alamu ekugcineni okuphambene, futhi ucingo alukwazi ukwenziwa ngalesi sikhathi (thatha i-S1240 switch njenge-alamu. isibonelo).
Isizathu siwukuthi imojula yokudlulisela (DM) ohlangothini luka-A ifile. Ngalesi sikhathi, ama-DM kuzo zombili iziphetho adinga ukwenziwa asebenze futhi. Lokhu kungase kubuyisele isifunda, noma isimo sokuqala singenzeka. Uma kwenzeka isimo sokuqala, vele ulandele indlela echazwe ngenhla.

Ukwehluleka kwezikhawu:

1. Ama-alamu embobo angu-2Mb/s akhiqizwa khona manjalo ngenxa yokwehluleka ngezikhathi ezithile, futhi imojula ye-DM eshintshwayo inomehluko ngesikhathi sokuhlonza ama-alamu, ngakho-ke kungase kwenzeke ama-alamu angapheli. Ngalesi sikhathi, ingaxazululwa ngokubhekana namaphutha ahlala njalo. Kodwa kungcono ukungasebenzisi indlela ye-loopback ye-DDF, ukuze ungaphazamisi isifunda.

2. I-alamu yembobo yeqoqo engu-2Mb/s
(1) Amamojula we-alamu agxile embobeni engu-34Mb/s noma imbobo engu-8Mb/s yezinto zokusebenza zokuphindaphinda. Lokhu kungase kube inkinga ngeqembu le-oda eliphezulu, noma inkinga ngentambo ye-adaptha ye-DDF, noma inkinga ngediski yomshini. Ngalesi sikhathi, ingatholwa ngendlela yokwehluleka unomphela.
(2) Ama-alamu amaningana e-DM weqembu le-trunk, lokhu kungase kube inkinga yokushintsha. Isibonelo, le nkinga yenzeka kanye ehhovisi lethu, futhi kwatholakala ukuthi ibangelwa umsebenzi onzima werejista yama-multi-frequency. Ngaleso sikhathi, ihhovisi lethu lasebenzisa ukusayinda okuhlobene nesiteshi, futhi inani lamafoni anethoni ekabili kubasebenzisi landa kancane kancane, okwabangela umthwalo osindayo wamarejista wamafrikhwensi amaningi. Kamuva, lapho kusetshenziswa uphawu lwe-No.7 phakathi kwamahhovisi, inkinga yaxazululeka.

3. I-alamu ekhethekile ijwayelekile ukuthi isixhumanisi ngasinye sokudlulisela esingu-2Mb/s sihlolwe ngokwehlukana, okungukuthi, iphuzu ngalinye ku-DDF alinayo i-alamu yokushintsha izihibe kuzo zombili iziphetho, futhi isilinganiso se-U-Link esine-multimeter siyinto evamile. , kodwa i-U- When Link ixhunywe kuswishi, kuvela i-alamu futhi ayikwazi ukusetshenziswa. Ngalesi sikhathi, yenza iluphu ohlangothini lokudlulisela lweqembu le-oda eliphansi kunoma yikuphi ukuphela kuka-A no-B, futhi uhlole nge-transmission analyzer endaweni efanayo ngakolunye uhlangothi. Kutholakala ukuthi i-ES ibonakala futhi sonke isixhumanisi sisesimweni esibucayi.
Indlela yokwelapha ukuhlola isigaba ngesigaba ngemitha kuze kutholakale isithiyo futhi isifunda sibuyiselwe.
