Ukusilela okusisigxina:
Ngeziphoso ezisisigxina, i-loop ingasetyenziselwa ekupheleni kwesinye, kwaye enye isiphelo ingabonakaliswa ukusuka kutshintshi okanye icandelo eligwetyiweyo ngecandelo kunye noluhlu ngoluhlu kunye ne-analyzer yokudlulisa.

1. Ii-alam zothumelo zivela ngababini. Ngokomzekelo, ukuba i-RJA (i-alamu ekude) iyenzeka kwicala le-A, ngoko ke icala le-B lingaba yi-LFA (isakhelo esiphuma kwi-alarm yokuvumelanisa) okanye i-AIS (ifumana i-alamu), kwaye ngamanye amaxesha zombini iintlobo ze-alamu zikhona; enye yi-LS ( Ukulahleka komqondiso) i-alarm.

Esinye sezizathu zokungaphumeleli: Kukho ingxaki ngomqondiso othunyelwe yi-DM ye-A-side, oko kukuthi, i-2Mb / s isignali ethunyelwe yimpazamo okanye ukuphazamiseka.
*Indlela yesigwebo: buyela umva ukuya kwisiphelo A kunye neDDF yesiphelo A. Ukuba kukho i-alarm ye-LS okanye ye-AIS kwisiphelo A, iyimpazamo.
*Isisombululo: Cela abasebenzi abakwigumbi lekhompyuter ukuba baqale ngokutsha okanye balayishe kwakhona imodyuli yokudlulisela ukucima isivusi.

Isizathu sesibini: Ingxaki yenzeke kwiqela eliphantsi ukusuka kwi-A ukuya kwi-B ekupheleni kwenye indawo, ibangela impazamo ye-2Mb / s yesignali okanye ukuphazamiseka.
*Indlela yesigwebo: Ukuba kukho ingxaki ukusuka ku-A ukuya ku-B phakathi kwamaqela aphantsi-phantsi kwiziphelo zombini ze-A kunye ne-B, i-alarm ye-AIS okanye ye-LFA iya kuboniswa kwi-B end. Ukuba isibonakaliso esivela kwiqela eliphantsi ukuya kwi-DM kwi-B end iphazamisekile, i-B end ibonisa i-alarm ye-LS.
*Isisombululo: Ngokwemiqobo efunyenweyo, okanye wenze kwakhona intloko kwi-DDF, okanye utshintshe i-U-Link, okanye utshintshe idiski yomatshini ukufezekisa injongo yokubuyisela isiphaluka.

2. Ii-alam zothumelo azibonakali ngababini. Ngokomzekelo, ii-alamu ze-AIS kunye ne-RJA zivela ngexesha elinye ekupheleni kwe-A, okanye i-alamu ye-LFA ibonakala ngaxeshanye, kodwa akukho alamu kwelinye icala, kwaye umnxeba awunakwenziwa ngeli xesha (thatha i-S1240 switch njenge umzekelo).
Isizathu kukuba imodyuli ye-relay (DM) kwicala le-A ifile. Ngeli xesha, ii-DMs kuzo zombini iziphelo kufuneka ziphinde zisebenze. Oku kunokubuyisela isiphaluka, okanye imeko yokuqala ingenzeka. Ukuba imeko yokuqala iyenzeka, landela nje indlela echazwe ngasentla.

Ukusilela okwethutyana:

1. I-alamu ye-2Mb / s nganye ye-port iveliswa ngokukhawuleza ngenxa yokungaphumeleli kwangethuba, kwaye imodyuli ye-relay yokutshintshela i-DM inomahluko kwixesha lokuchongwa kwee-alamu, ngoko ke ii-alamu eziphelileyo zingenzeka. Ngeli xesha, inokusonjululwa ngokujongana neziphene ezisisigxina. Kodwa kungcono ukuba ungasebenzisi indlela ye-loopback ye-DDF, ukuze ungaphazamisi isiphaluka.

2. I-Batch 2Mb / s i-alamu ye-port
(1) Iimodyuli ze-alamu zigxininiswe kwi-port ye-34Mb / s okanye i-8Mb / s port yesixhobo sokuphindaphinda. Oku kunokuba yingxaki kwiqela le-oda eliphezulu, okanye ingxaki ngentambo yeadaptha ye-DDF, okanye ingxaki ngomatshini wediski. Ngeli xesha, inokubonwa ngendlela yokusilela ngokusisigxina.
(2) Ii-alamu ezininzi ze-DM zeqela le-trunk, oku kunokuba yingxaki yokutshintsha. Ngokomzekelo, le ngxaki yenzeke kanye kwiofisi yethu, kwaye yafumanisa ukuba ibangelwa ngumsebenzi onzima werejista ye-multi-frequency. Ngelo xesha, iofisi yethu yayisebenzisa umqondiso ohambelana netshaneli, kwaye inani leefowuni zethoni ezimbini zabasebenzisi zanda ngokuthe ngcembe, nto leyo eyabangela umthwalo onzima kwiirejista ezininzi. Kamva, xa umqondiso onguNo.7 wasetyenziswa phakathi kweeofisi, ingxaki yasonjululwa.

3. I-alarm ekhethekileyo iyinto eqhelekileyo kwikhonkco nganye ye-2Mb / s yokuhanjiswa ukuze ivavanywe ngokwahlukileyo, oko kukuthi, indawo nganye kwi-DDF ayinayo i-alamu yokutshintsha iziphelo zombini, kwaye ukulinganisa kwe-U-Link nge-multimeter nayo iyinto eqhelekileyo. , kodwa i-U- Xa ikhonkco iqhagamshelwe kwiswitshi, i-alam iyenzeka kwaye ayinakusetyenziswa. Ngeli xesha, yenza i-loop kwicala lokudluliselwa kweqela eliphantsi kwinqanaba le-A kunye ne-B, kwaye uvavanye nge-analyzer yokudlulisela kwindawo efanayo kwelinye icala. Kufunyenwe ukuba i-ES ibonakala kwaye yonke ikhonkco ikwimeko enzima.
Indlela yonyango kukuvavanya icandelo ngecandelo kunye nomitha de kube umqobo ufunyenwe kwaye isiphaluka sibuyiselwe.
