Firstmakesurethatyou haveinsertedthepoweradapteroftheZXDSL
831/831B/831II/831BII intoaworkingpowersocketandthattheZXDSL
831/831B/831II/831BII hasbeenpoweredon (theswitchbutton ispresseddown).If
theindicatorsarestill offafterconfirmationoftheaboveitems,thehardwareis
damagedprobably.You maycontactlocaloperatorsformaintenance. Never
dismantle the equipmentby yourself.
2WillADSLaffectthetelephoneconversationquality?Willmakingphonecalls
cause aslowonlinerate?
ADSLseparatesvoicesfromdatathroughthefrequencydivisionmultiplexing
technology.Therefore, voicesanddatarun indifferentpathswithoutmutual
interference. Neithertheaccessratenorconversation qualitywill fall evenifyou are
ina call andon line simultaneously.
3 Howtoproperlyinstall telephone extensionsorotherdevicesontheADSLline?
Itisrecommendedtofirstconnectthe ADSLsplittertothe incomingcustomerend of
thetelephonecable, andthenconnectthephonesetstothesplitterinterfaces.
Installing atelephonedirectlybeforethesplitterwill leadtoafailureofconnection
betweentheZXDSL831/831B/831II/831BIIandthedevice atcentraloffice side, or
afailureofaccessintotheInternet,oraslowconnection speed.Connecting some
otherelectronicdevicesbetweentheincomingcustomerendandsplittermayaffect
theADSLcommunications(since ADSLhasahigherrequirementfortheline

requiredtobeconnectedbeforethesplitter,youshouldseriallyconnectthefilter
MicroFilterbeforethephonesets(Generally,tominimize interference, onlyone
filterMicroFiltercanbe hangbefore thesplitter).
4 Sometimes, theADSLuserscannotgainaccess tothe Internetnormally
FirstcheckwhethertheZXDSL831/831B/831II/831BIIisinthenormalstate
(Checktheindicatorswiththisusermanual).Ifyes,thecomputerorapplication
networkmaybefaulty,whichisunrelatedwithADSL.If theADSLModemis
abnormal, checkthe statusofindicatorsoneby one toremove the fault.
Youaresuggestedtofirstmakesurethefollowing itemsbeforeseekinghelpfrom

6WhatarereasonsforADSLsynchronizationfailure(alsoreferredtolinkdown
orlinkestablishmentfailure)?
If theADSLsuddenlyfailstobesynchronized(linkdown)duringapplication,
usuallythe DSLindicatorofthe MODEMwill notbesolidon. You aresuggestedfor
checkup inthe followingsequence:
1. Firstcheckthe qualityofincomingcablesandincoming cable connectors.
2.Install theADSLModemcorrectlybasedon theuserguide, tominimizethe
numberoftaps.
3.CheckwhetherthetelephonecablesandADSLareingoodcontactorwhetherthe
telephone cablesarenormal.
4.TrytodisconnectthesplitteranddirectlyconnecttheADSLModemtothe
incomingcustomercableendtoensurethattheproblemisnotduetoimproper
installation orincomingcustomerlinequality.IftheADSLcanbesynchronized
again,it meansthatinstallation oftheincoming customerpartisimproper.Please
reinstall it according tothe userguide.
5.IftheADSLstill failstobesynchronizedaftertheADSLModemhasbeen

whetherit isdue toexternalline failure orModemfailure.
6.Ifthesplitterproblemisdetermined,call theoperatorsformaintenanceor

7.Theproblemmaybealsoduetotheendoffice equipmentfault oftheoperator.
Call the operatortoconfirmit.
8. Too longconnectioncablebetweenthesplitterandADSLModemmaycausepoor
anti-interference performance andsynchronization difficulty.Therefore,the
connection cableshouldnotbe toolong.
