SR820acLANChoices
Youcanconnectupto252clientcomputerstotheSR820acusingoneoranycombinationofthefollowing
networkconnections:

Wi‐FiwirelessLAN(WLAN) 


Ethernetlocalareanetwork(LAN) 
WirelessLAN
Wirelesscommunicationoccursoverradiowavesratherthanawire.Likeacordlesstelephone,aWLAN
usesradiosignalsinsteadofwirestoexchangedata.Awirelessnetworkeliminatestheneedforexpensive
andintrusivewiringtoconnectcomputersthroughoutthehomeoroffice.Mobileuserscanremain
connectedtothenetworkevenwhencarryingtheirlaptoptodifferentlocationsinthehomeoroffice.
EachcomputerorotherdeviceonaWLANmustbeWi‐Fienabledwitheitherabuilt‐inorexternal
wirelessadapter.
Laptops—Useabuilt‐inwirelessnotebookadapter,awirelessPCMCIAslotadapter,orawirelessUSB
adapter.
Desktops—UseawirelessPCIadapter,wirelessUSBadapter,orcompatibleproductinthePCIslotorUSB
port,respectively
SampleWirelessNetworkConnections(SR820acmodelshown)


Yourmaximumwirelessoperationdistancedependsonthetypeofmaterialsthroughwhichthesignal


mustpassandthelocationofyourSR820acandclients(stations).ADTRANcannotguaranteewireless
operationforallsupporteddistancesinallenvironments.
Note:Togetbetterwirelesscoverage,pleaseputyourSR820ac

WiredEthernetLAN
YoucaneasilyconnectanyPCwithanEthernetcabletotheSR820ACEthernetport.BecausetheSR820ac
Ethernetportsupportsauto‐MDIX,youcanuseastraight‐throughorcross‐overcabletoconnectahub,
switch,orcomputer.UseCAT‐5,orbetter,cablingforallEthernetconnections.
SampleEthernettoComputerConnection(SR820acmodelshown)
AwiredEthernetLANwithmorethanfourcomputersrequiresoneormorehubs,switches,orrouters.
Youcan:


GettingStarted
InsidetheBox
BeforeyouinstalltheSR820acVoiceGateway,verifythatthefollowingitemsareincludedintheboxwith
theSR820AC:

Youmusthavethelatestservicepacksandpatchesinstalledonyourcomputerforyouroperatingsystem.
Youwillneeda75‐ohmcoaxialcablewithF‐typeconnectorstoconnecttheSR820actothenearestcable
outlet.IfaTVisconnectedtothecableoutlet,youmayneeda5to900MHzRFsplitterandtwo
additionalcoaxialcablestousetheTVandtheSR820ac.
BeforeYouBegin
TakethefollowingprecautionsbeforeinstallingtheSR820ac:

TheSR820acshouldalwaysbeputinaverticaluprightposition. 


Thereshouldalwaysbeaclearanceofatleast30mmbetweeneachofthesidecoversand
anyobjectthatmightblocktheairflowthroughtheunit.



Iftheunitisattachedbymeansofthecomprisedbracket,theFNCconnectorshould
protrudeonthelefthandsidewhenattachingtheunittothebracket.



Strivetodeploytheunitinacentrallocationofthelivableareaswheremostofthewireless
devicesareused.


15

Takeintoaccountthefollowingenvironmentalconditions
Avoidphysicalobstructionsofthewirelesssignalforoptimallineofsight(walls,ceilings,
floors,furniture)
Avoidreflectivesurfaces(Wi‐FisignalsmaybounceofWindows,mirrors,metalfilecabinets,
stainlesssteelcountertops,aluminumfoil)

Avoidelectricalhomeapplianceslikemicrowaves,homesecuritysystems,cordless/mobile
phones,fansthatmightcauseinterferencewiththewirelesssignal

Postponeinstallationuntilthereisnoriskofthunderstormorlightningactivityinthearea.

Toavoidpotentialshock,alwaysunplugthepowercordfromthewalloutletorotherpower
sourcebeforedisconnectingitfromtheSR820ACrearpanel.

TopreventoverheatingtheSR820ac,donotblocktheventilationholesonthesidesofthe
unit.Donotopentheunit.ReferallservicetoyourInternetServiceprovider.
Checkthatyouhavetherequiredcables,adapters,andadaptersoftware.Verifythattheproperdrivers
areinstalledfortheEthernetadapteroneachnetworkedcomputer.ForinformationonWLANsetup,see
SettingupYourWirelessLAN.
SystemRequirements
Yourcomputermustmeetthefollowingminimumrequirements:
ComputerwithPentium©classorbetterprocessorWindowsXP,Windows7,Windows8,
Windows10,Macintosh,orUNIXoperatingsystemwithavailableoperatingsystemCD‐


Anywebbrowser,suchasMicrosoftInternetExplorer,NetscapeNavigator®,orMozilla®
Firefox®
ConnectingtheSR820ac
Beforestarting,besurethecomputeristurnedonandtheSR820acpowercordisunplugged.
1. Connectoneendofthecoaxialcabletothecableoutletorsplitter.

2. ConnecttheotherendofthecoaxialcabletotheCableconnectorontheSR820ac.Hand‐
tightentheconnectorstoavoiddamagingthem.

3. PlugthepowercordintothePowerportontheSR820ac.

4. Plugtheotherendofthepowercordintoanelectricalwalloutlet.

Thisautomaticallypowersonthegateway.Youdonotneedtounplugthegatewaywhenit
isnotinuse.ThefirsttimeyouplugintheSR820ac,allowit5to30minutestofindandlock
ontheappropriatecommunicationschannels.

5. Plugtheotherendofthetelephonecordofasingleortwo‐linetelephoneintotheTEL1/2

SettingupInternetAccess
AfterinstallingtheSR820ac,checkthatyoucanconnecttotheInternet.YoucanretrieveanIPaddress
foryourcomputer’snetworkinterfaceusingoneofthefollowingoptions:
RetrievethestaticallydefinedIPaddressandDNSaddress

AutomaticallyretrievetheIPaddressusingtheNetworkDHCPserver
TheADTRANSR820acVoiceGatewayprovidesaDHCPserveronitsLAN.Itisrecommendedthatyou
configureyourLANtoobtaintheIPsfortheLANandDNSserverautomatically.
MakesureallcomputersonyourLANareconfiguredforTCP/IP.AfterconfiguringTCP/IPonyour
computer,youshouldverifytheIPaddress.
Note:ForUNIXorLinuxsystemsfollowtheinstructionsinthe
applicableuserdocumentation.
