remotemanagement capabilities,configurablesignalingto workwith PBX, KTS, and/or telephone.
Building onstate-of-the-artadvanced VoIPrelatedtechnology.PLANETVVIPseries offers various
features: echocancellation, VoiceActivityDetection(VAD),Comfort Noise Generation(CNG) , lost
packet recoveryalgorithms andoptimized voiceand FAX coders tobringusers superiorvoicequal-
ity, andbest compatibilitywith major Internet telephonyservice providers.
1.2 Networking Protocols
VIPsupports severalindustry-standard networking protocols requiredfor voice communication. The
followingtable describesthese protocols.
Networking Protocol Description
Internet Protocol(IP) IP is a messaging protocolthat addressesandsendspackets across the
network.To
enable IPprotocol, VIPmust have a static IP address,subnet,
and gateway assignedto it.
Voiceover IP Protocol
(VoIP)
VoIP enablesVIP to transfer voicecommunications overanIPnetwork.
VIPemploys ITU-T SIPprotocolforsetting up call with one another.
Trivial FileTransfer
Protocol(TFTP)
TFTP allowsyou to transfer files over thenetwork.VIP implementsa
TFTP client allowingyoutodownloadnewrevision firmware fromaTFTP
server. TheTFTP client requires a TFTP server in your network.

Chapter 2 Installing VIP
Thischaptergives informationon how to installVIP.
2.1 Network Requirements
ForVIP successfully operate inyour network, yournetworkmust meet the followingrequirements:
1. A working10/100Base-TEthernet. VIPconnects toInternet viaan Ethernet LAN.
2. IPnetworkthatsupportsgateway,and subnet mask.You llneed one staticIPaddresstoas-
sign VIP.
2.2 Installing VIP
VIPcanbe usedinadesktopconfiguration. Ensurethat VIPisplaced inaclean, well-ventilated,
and vibration-free environment.
When VIPisplacedonadesktop,becertainthat theunitisplacedon asturdy,flat surface,near a
grounded power outlet.Atleastthreeinchesofclearance must beprovided onbothsides ofVIP
for wellventilation.
2.3 Connecting to the telephonydevices
VIP-050supports threetypes ofTIM.OneisFXO,FXSandthe other isE&M.Each modulehas
four ports for connecting totelephony devices. VIP-450 equips two FXO andtwoFXSinterfaces to
havethegreat flexibilityofPBXconnection (FXO),and telephone orFAXmachineconnection
(FXS).
VIP-FXO moduleisdesignedfor connectingtoPBXs(extensionline) or centralofficeswitches(CO
line).
VIP-FXS moduleis designedfor connectingto analogtelephonesets or G3faxmachines.
Connectingthe telephonydevicesto theappropriateRJ11 ports ontheTIM.
Warning:connectionof incorrect telephony devicesto theports on the TIMcancause permanent
damagetotheTIMand/or VIP.
2.4 Connecting to the Network
TheRJ45network port on the front panelsupports 10/100Mbpshalf-duplexconnectionto Ethernet
Network.Youcanuse either category3or5straight-through UTPcablefor 10Mbps connections,
butuse Category5for 100 Mbps connections.Toconnectto Ethernet, insert oneendofthe

Chapter 3 VIPConcepts
VIPenables the transmissionofvoiceandfax trafficover any IPnetworkbydigitizing voice andfax
signals,encapsulatingthe informationwithinIPpackets, andthen sendingthe packetsacrossthe
IP network
3.1 HowVIPOperates
1. The TIMinside VIPdigitizes analogvoice signalsat8Kbps.
2. VIPsystem software handles the:
Ÿ Captureof telephone number presentedas DTMF tones.
Ÿ Mappingthe telephone number totheIPaddress ofremote VIP.
Ÿ Setting up callswithremote VIPs utilizing SIP callcontrolprotocol.
Ÿ Digitizing,compressingand encapsulatingthe voiceintoIPpackets andtransmissionofthe
IP packetsonto the Ethernet LAN.
3. ArouterattachedtotheLAN forwardstheIP packetsacrosstheWAN,wheretheywill bere-
ceivedby another VIPatthe remote.
4. The process isreversedat theremote VIP.
3.2 ATPM
Toallowyoutoeasily dialatelephoneor faxonthenetwork,VIPmapsaseries ofdialeddigits to
the IP address oftheremoteVIP whose phoneor fax youare calling.Thismappinginformation is
containedin a database inside each VIPcalledthedial plan.
Basedon the dialplan the AddressTranslationandParsing Manager (ATPM)insideVIPtranslates
telephonynumbers to IP addresses ofremote VIPs. TheATPMcollectstelephone numberdialed
byusers, decides whether thedialstring ispartofthedialplanand,ifitis, mapsitaremote VIP.
When thecallisset upto thedestination,asubstringofthe originaldialstringwillbesentalongto

3.3 Destination

minals the call at oneofthetelephonyports. Thedestinationfor the callisthe telephonyport where

3.4 Hunt Group
Insteadofdirectlymapping aphone numberto adestination, theATPMfirst mapsthephonenum-
berto agroup ofdestinations knownas aHuntGroup. Ahunt groupisagroup ofdestinations that
are equivalent. For example, thecustomersupport groupofacompanymighthave 20peo-
plewhocanhandle support calls. Access tocustomersupport is through asinglephone
numberbutthenext availablesupportpersonis actuallyconnecteduponeachincoming
call. These20phones wouldbeconfiguredasahunt group.Ahuntgroupconsists ofa
phonenumberandalistofdestinations(members of thegroup). When anincomingphone
number matches the phonenumber ofthehuntgroup, VIPattempts toterminatethecallat each of
the destinations inthehuntgroup, oneata timeuntila call is successfully completed.
Everydestinationthat can bereached by dialing aphone numberisamember ofat least one hunt
group. When anaddress ispresentedtoATPMfor lookup, the output isahunt groupIDnumber.
Asasecond step,thehunt groupIDispresented to ATPMto get thelist of members. Toeffectively
bypassthehunt group feature, simply makeauniquehunt group for eachdestinationandone

3.6 DTMFRelay
Voicefrom PSTN iscompressed by VIPbefore sending acrosstheIP networkandthendecom-
pressedbythe destinationVIP.Thevoice coderssupported by VIPare designedfor ideallycom-
pressingand decompressinghumanvoice.Ifthe compression /decompressionprocessis per-
formedonDTMFtone which needstobeconveyed acrossIPnetwork,distortionmightbetoosig-
nificant to benot cognizableinthe receiving end.To overcometheshortcomingthat thevoice cod-
ers cannotperfectlyencodeDTMFtone,VIP encodes DTMFtoneinto specialpackets. Thepack-
ets arethensentto the destinationVIPviaaseparate IP connection.ThedestinationVIPdecodes
the packets,generates the DTMFtone,and thensendsthetonetothePSTN. ThewayVIP han-
dles DTMFtone isso called DTMFrelay.
VIPhandles DTMFrelayper SIPspecifications. CertainthirdpartyVoIPdevicesmayhandle DTMF
relayper IMTCstandard. ForVIP to interoperate withthoseVoIPdevices, users need to specify
which remoteVoIPdevicesusesIMTCconforming DTMFrelaytechnique. Refer toCLIcommand
for detailed information on how to selectDTMFrelay mode.
