Kukundikana zvachose:
Nokuda kwezvikanganiso zvechigarire, loop inogona kushandiswa kune imwe mugumo, uye imwe mugumo inogona kuratidzwa kubva kune chinja kana kutongwa chikamu nechikamu uye layer ne layer ine transmission analyzer.

1. Maaramu ekutakurisa anoonekwa ari maviri maviri. Somuenzaniso, kana RJA (aramu iri kure) ikaitika kudivi reA, ipapo rutivi rweB runogona kunge rwuri LFA (frame out of synchronization alarm) kana AIS (kugamuchira aramu), uye dzimwe nguva marudzi maviri earamu aripo; imwe yacho iLS (Signal loss) alarm.

Chimwe chezvikonzero zvekutadza:Pane dambudziko nechiratidzo chakatumirwa neA-side DM, kureva kuti, 2Mb/s chiratidzo chakatumirwa kukanganisa kana kukanganisa.
*Nzira yekutonga: loop back to end A neDDF yekugumisira A. Kana paine alarm yeLS kana AIS pamagumo A, imhosva.
*Solution: Bvunza vashandi vari mukamuri rekombuta kuti vatangezve kana kurodhazve modhi relay kuti vabvise alarm.

Chikonzero chechipiri: Dambudziko rinoitika muboka rakaderera kubva kuA kusvika kuB kuguma kune imwe nzvimbo, zvichikonzera kukanganisa kwechiratidzo che 2Mb / s kana kukanganisa.
*Nzira yekutonga: Kana paine dambudziko kubva kuA kusvika kuB pakati pemapoka akaderera-kumigumo ese A neB, alarm yeAIS kana LFA icharatidzwa paB end. Kana iyo chiratidzo kubva kune yakaderera kurongeka boka kuenda kuDM kumagumo eB ikakanganiswa, iyo B yekupedzisira inoratidza alarm yeLS.
*Solution: Zvinoenderana nezvipingamupinyi zvakaonekwa, kana kugadzirazve musoro paDDF, kana kutsiva U-Link, kana kutsiva dhisiki yemuchina kuti uwane chinangwa chekudzoreredza dunhu.

2. Maaramu ekutumira haaoneki ari maviri maviri. Semuyenzaniso, maaramu eAIS neRJA anoonekwa panguva imwe chete kumagumo A, kana maaramu eLFA anoonekwa panguva imwe chete, asi hapana alarm kumagumo, uye kufona hakugone kuitwa panguva ino (tora S1240 switch se muenzaniso).
Chikonzero ndechekuti relay module (DM) kudivi reA yakafa. Panguva ino, maDM ari kumativi ese ari maviri anoda kuvhurwazve. Izvi zvinogona kudzorera dunhu, kana mamiriro ekutanga anogona kuitika. Kana mamiriro ekutanga akaitika, ingotevera nzira inotsanangurwa pamusoro apa.

Kukundikana kwepakati:

1. Munhu mumwe nomumwe 2Mb / s maaramu emagetsi anogadzirwa pakarepo nekuda kwekukundikana kwepakati, uye switching relay module DM ine mutsauko munguva yekuzivikanwa yearamu, saka mazamu asina kupera anogona kuitika. Panguva ino, inogona kugadziriswa nekutarisana nezvikanganiso zvekusingaperi. Asi zviri nani kusashandisa nzira yeDDF loopback, kuitira kuti usakanganise dunhu.

2. Batch 2Mb/s port alarm
(1) Iyo alarm module yakanangidzirwa pane 34Mb / s chiteshi kana 8Mb / s chiteshi chemidziyo yekuwanda. Izvi zvingava dambudziko neboka repamusoro-soro, kana dambudziko neDDF adapter cable, kana dambudziko nemuchina disk. Panguva ino, inogona kuonekwa nekusingaperi kukundikana nzira.
(2) Akawanda maDM maalarm eboka retrunk, iyi inogona kunge iri dambudziko rekuchinja. Semuenzaniso, dambudziko iri rakaitika kamwechete muhofisi yedu, uye yakawanikwa kuti yakakonzerwa nebasa rinorema re-multi-frequency register. Panguva iyoyo, hofisi yedu yakashandisa kusaina kwakabatana nechiteshi, uye nhamba yemafoni maviri-toni yevashandisi yakawedzera zvishoma nezvishoma, izvo zvakakonzera kuremerwa kwemabasa kune akawanda-frequency marejista. Gare gare, apo chiratidzo cheNo.7 chakashandiswa pakati pemahofisi, dambudziko rakagadziriswa.

3. Alarm yakakosha yakajairika kune yega yega 2Mb/s transmission link kuti iedzwe yakaparadzana, kureva kuti, imwe neimwe paDDF haina alarm ye switching loops kumagumo ese, uye iyo U-Link kuyerwa ine multimeter zvakare yakajairika. , asi iyo U- Kana Link yakabatana kune switch, alarm inoitika uye haigone kushandiswa. Panguva ino, gadzira loop padivi rekutapurirana reboka rakaderera pane chero kumagumo kweA neB, uye edza neainalyzer yekutapurirana panzvimbo imwechete kune imwe mugumo. Inowanikwa kuti ES inoratidzika uye iyo yose link iri mumamiriro ezvinhu akaoma.
Nzira yekurapa ndeyekuedza chikamu nechikamu nemamita kusvikira chipingamupinyi chawanikwa uye dunhu radzorerwa.
