www.vyyo.comSystem Configuration Introduction – p. 10Chapter 1. System ConfigurationIntroductionThis guide is intended as a practical aid for the Technicians, Operators and FieldService Engineers responsible for quickly configuring Vyyo systems at mostcommon installations. It is not intended as a substitute for a detailed referencemanual.NOTE: Throughout this manual the terms modem andWMU are used interchangeably. The term “WMU” refersto “Wired/wireless Modem Unit”. In some instances theactual modem model (V280, V311, etc.) may be used ifthe information is specific to that modem. The term “WMTS” is used interchangeably with “XMTS”.XMTS is an acronymn for “Xtend Modem TerminationSystem”. Both terms appear in the software and werederived from the term “CMTS”, “Cable ModemTermination System”.The term “WMU” will appear in the software occasionally.It is an acronymn for “Wireless Modem Unit” and is usedinterchangeably with “CM” (Cable Modem).1.1 OverviewThe system acts as an RF bridge between a network, typically the Internet or thePublic Switched Telephone Network (PSTN) (at the head end) and customerequipment at the other end of the RF link.It may be visualized as a three layer protocol stack. The highest layer may beany one of the following: IP, E1/ T1 or PSTN.All systems include the IP capability, which is required for network management.The E1/T1 capability requires an additional plug-in card at the WMTSInternetorPSTN Wireless or HFC NetworkCustomer PremisesWMTSCableModem(CM)CustomerEquipment
www.vyyo.comSystem Configuration Introduction – p. 11(Cable/Wireless Modem Termination System) end and an E1/T1 capablecable/wireless modem at the downstream end.The data from the IP, E1/T1, or PSTN layer are encapsulated as DOCSIS frameswhich in turn are converted into RF signals and sent over the air or via an HFC(Hybrid Coax Fibre) plant between the WMTS and modem.Important Note: connectivity MUST be obtained at eachlayer, beginning with the lowest (RF link) in order toestablish full communication.
www.vyyo.comSystem Configuration Introduction – p. 12The following diagram illustrates this in the form of a three layer protocolstack:This illustration shows how a complete system is connected:Connection Legend:Blue = 100BaseT EthernetGreen = RF Coaxial cableBlack = T1/E1Grey = RJ-11IP, E1/T1, POTSRF LinkDOCSISWMTSModemIP, E1/T1, POTSRF LinkDOCSISLayer 3Layer 2Layer 1 RxTxV280 Modem100BaseTIP NetworkMTAPCLine #2FaxLine #1PhoneRJ-11RJ-11PSTNH.323v2 orMGCP, VOIPPacketVoiceServerE1/T1V311 E1/T1 ModemIP RouterProvisioningServicesWMTSInternetTelephoneSwitchPBXIntranetRF CoaxRF Cloud orCable Plant100BaseTE1/T1100BaseT
www.vyyo.comSystem Configuration Introduction – p. 13There are different configuration requirements for each layer and differentsoftware tools accomplish this task. The configuration of the RF link is typicallyunique to each installation with the particular downstream and upstreamfrequencies, modulations and bandwidths being the critical parameters that mustbe set on the modem and WMTS.Whereas there is no set standard for implementing an RF link, DOCSIS is a fullyspecified protocol as are the upper layers (IP, E1/T1 or PSTN). The followingsections will describe the currently available system components (equipment)then detail how to configure each of them in turn.1.2 Equipment CapabilitiesThere are several different modems available, the simplest being the DOCSISmodems with IP-only capability. All of the other modems use these as theirfoundation.The WMTS used at the head end is the other major component. There is onlyone basic configuration, which is augmented with additional plug-in cards toaccommodate E1/T1 and PSTN capabilities.NOTE: The term WMTS was originally conceived as“eVyyoed” CMTS for use in a cable plant, hence the “X”.This was followed by WMTS in which the “W” indicates a“wireless” CMTS. For practical purposes these terms areinterchangeable and in some places the software usesthe term “WMTS” when referring to any one of thesesystems.1.3 WMTSThe basic WMTS is a chassis with a power supply and a mid-plane PCI bus thataccommodates plug-in cards at the front and rear. Two redundant power supplycards are provided at the right end of the front of the chassis.The minimum required hardware configuration for an IP-only system consists ofone "HOST" card and three "Universal" cards. One Universal card acts as a"Control and Forward" (C&F) card, one as the "Upstream" digital card and one asthe "Downstream" digital card. These latter two cards are attached to RF cardsin the rear slots.E1/T1 capability may be added by replacing the Host card with a Master4 card,and adding one or two E1/T1 interface cards in the rear slots to provide 12 or 24E1/T1 ports, respectively. An DS3 version of the Master4 card which allows 28T1 connections is also available. This card has two coax connectors (one forreceive and one for transmit) in place of the E1/T1 interface cards.The HOST or Master4 card serves as the PCI bus arbiter and provides thesystem clock and timing. When the WMTS boots, the Master4 card initializes,then identifies the C&F card. The C&F card then directs the configuration anddownloading of relevant application software. The C&F card is connectedthrough a 100 BaseT Full Duplex connection to the switch or router and used totransport data (including management packets) through the system.
www.vyyo.comSystem Configuration Introduction – p. 14All Universal cards are the physically identical: the card attached to each of themin the rear slots and the application downloaded during initial startup determinethe function of the card (Upstream, Downstream or Control & Forward).In the rear slots, one Downstream and one Upstream RF interface card arerequired. Each of these corresponds to its companion Universal card. The“Quad” downstream card has four RF connectors and provides four downstreamchannels. The “Hex” upstream card has six RF connectors and provides sixupstream channels.Note: All Downstream cards have a fixed outputfrequency of 44 MHz which must be converted up per thelocal requirements.Upstream cards may be configured to receive anyfrequency from 5-65 MHzFigure 1-1. The WMTS Chassis with (from left to right) Upstream card,Downstream card, Control and Forward card, MASTER4 card, and PowerSupplies shown.The WMTS is mounted in a standard 19” by 6U high rack-mounted chassis.The chassis has a fan tray above the unit, bringing the total height required
www.vyyo.comSystem Configuration Introduction – p. 15in the rack, to 8U. The eight bay chassis contains eight slots in the front, sixslots in the rear, and a mid-plane card in between, used to interface thecards. Blank panels cover unused slots.A standard 33 MHz, 32 bit Compaq PCI bus is used to transfer traffic anddata between the system cards. The power supplies, Master4 card and theuniversal cards are inserted in the front slots of the chassis. The QuadDownstream, Hex Upstream, and E1/T1 cards are inserted in the rear slotsof the chassis.The ON/OFF power switch and the fuse are located in the rear of the powersupply.Figure 1-2.

www.vyyo.comSystem Configuration Introduction – p. 161.4 Modems1.4.1 Modems with DOCSIS and IP onlyThe V280 is Vyyo’s “IP-only” modem. It uses an RJ45 connector (shown below)on the rear panel to provide IP connection to the customer’s equipment. TheV280 supports up to 63 data users simultaneously and provides privacy,authentication, service classification, prioritization, and traffic shaping.The USB connector is not supported at this time. Check with Customer Supportfor updates as they become available if you need this capability.Figure 1-3. V280 Rear PanelFigure 1-4: V280 Front panelHyperterm (a Windows terminal application which permits either a serial or directIP connection and is used in the following examples) or Telnet may be used toconnect the modem to a computer to configure parameters in the modem, suchas the downstream receive frequency. Any equivalent software utilities may beused.A basic WMTS unit (without E1/T1 capability) is all that is required at the headend to complete an IP connection.
www.vyyo.comSystem Configuration Introduction – p. 171.4.2 Modems with DOCSIS, IP and E1/T1The V311 is a V280 modem (to provide the DOCSIS layer) with one E1/T1interface (via an RJ45 connector on the front panel) added. In addition to IPconnectivity, it supports circuit switched E1/T1 applications. It has one 100BASE-T port for IP data and one E1/T1 port which can support up to 32/24 timeslots.The E1/T1 application supports framed or unframed E1/T1 services. In the caseof unframed configuration, all 32/24 time slots (including time slot 0) are deliveredover the air.In the case of framed E1/T1 configuration, a full or fractional E1/T1 (any numberup to 31/23 time slots) can be delivered.The V311 modem is shown in this image:Figure 1-5: V311 Modem
www.vyyo.comSystem Configuration Introduction – p. 18The V312 is identical to the V311 but has two E1/T1 interfaces instead of one.The WMTS at the head end requires one or two E1/T1 interface cards (pluggedinto the rear slots, with the second E1/T1 card attached to the first one as adaughter board) to work with the V311 or V312. The E1/T1 connection will beterminated at one of the ports on this (rear) E1/T1 interface card(s). In addition,a separate software load is required.All modems have four LED indicators, described below.Figure 1-6. LED IndicatorsTable 1.1 LED Indicators, Functions, and Conditions1.4.3 Modems with DOCSIS, IP and PSTNThe V313 is a V280 (for the DOCSIS layer) with a PSTN interface added: thisphysical interface (provided with the V313) comprises four RJ45 connectors,each of which connects to a special cable terminated in four RJ11 connectors,allowing a total of sixteen PSTN devices to be connected.The WMTS at the head end requires an E1/T1 card and a V5.2 AN stack(additional software available from Vyyo) to work with this unit. If you plan todeploy the V313 please contact your Vyyo representative.
www.vyyo.comSystem Configuration Introduction – p. 191.4.4 Modems with DOCSIS and IP Only With Built in UHF RadioThe V284 modem is a basic V280 modem integrated with a built-in UHF radiothat provides an upstream RF output in the 710-716 MHz range. Internally theV284 has a factory set intermediate frequency of 44MHz which is converted up toyield an appropriate upstream frequency (This is preset at the factory for 700MHzin the United States).The downstream frequency ranges from 740-746MHz. Note that the RF setup ofthis radio requires appropriate preplanning owing to the complexity introduced bythe internal UHF radio. Please reference the UHF System Installation Guideand/or your local system engineer.Figure 1-7: V284 Modem

www.vyyo.comConfiguration Overview – p. 21Chapter 2. Configuration OverviewThis section of the System Configuration Guide features a short overview of eachcomponent/layer of the System including the WMTS and the modems. The lastsection is a summary presented as a matrix that shows the relationships betweenthe various tools and files. The components and layers are described below.• Network Serverso DHCP Servero TFTP Servero Time of Day (ToD) Server• RF Link Layer• DOCSIS Layer2.1 Network ServersThe following servers are required for successful completion of modeminitialization. They will be accessed by the modem and the WMTS at specificpoints during the registration and installation process.2.1.1 DHCP ServerThis server binds the modem’s MAC address to both its Network IP addressand its configuration (or “boot”) file, which contains several important systemspecific parameters required for the modem to communicate with the WMTS.Viewing this information can help in troubleshooting any problems which mayoccur.2.1.2 TFTP ServerThis server downloads the selected configuration file to the modem duringthe registration process when the modem requests it. It also downloads filesand configuration information to the WMTS. This information is used forinitial (first time) startup and for troubleshooting.2.1.3 Time-of-Day (TOD) ServerThis server provides the Time of Day to the modems and the WMTS. Itallows the WMTS and the modem to coordinate their timing.2.2 RF Link LayerThis network layer is unique for each installation and depends on theavailable frequencies, the frequency plan, the specific hardware used for theinstallation, and other factors.
www.vyyo.comConfiguration Overview – p. 22Your System Engineer must develop a detailed system plan that accountsfor each of these variables. This plan must include the assignments ofdownstream frequencies, modulations (and other RF parameters) andupstream channel IDs assigned to the various modems deployed in thenetwork. If the modems are to be used with E1/ T1 connections, all relatedparameters, especially QoS (Quality of Service, also referred to as Class ofService) parameters, also need to be defined (these are discussed later inthis document.)NOTE: The methods to define these factors are uniqueto each customer and are outside the scope of thisdocument. They are part of the site preparation and pre-planning, including any “overbooking” scheme that maybe desired. Please consult your Vyyo representative orsystem integrator for assistance.The Downstream and Upstream frequencies, modulations and bandwidthsMUST be pre-determined in order to proceed with the configuration of theWMTS and the modems. Each modem must be assigned to a specificWMTS Upstream Channel (the upstream channel is referenced by itsChannel ID which identifies the physical port.) The Upstream channel mustbe configured for a specific frequency, modulation and bandwidth or symbolrate.NOTE: The WMTS must be configured to use the correctUpstream and Downstream parameters. This is doneusing the Vyyo Configuration tool.It also recommended that each modem is assigned to a particularDownstream channel (or set of channels.) The modem can use Downstreamchannel discovery, however; it is typically not used since it takes muchlonger to discover the correct frequencies.Using pre-determined frequencies also allows greater control over the RFfrequency assignments and can distribute network bandwidth moreefficiently. A range of frequencies can be defined in the modemconfiguration file to cover all customer assigned bands and to minimizefuture re-configuration.NOTE: The modem’s Downstream ferequency is presetat the factory but may be changed on the modem byusing a direct Telnet connection. See Section 5.4 Settingthe Modem’s Downstream Frequency for details.2.3 DOCSIS LayerThe most important items that must match are:The WMTS Downstream Frequency and the modem Downstream FrequencyThe WMTS Upstream Channel ID and the modem Upstream Channel ID (theirassociated parameters must also match.)
www.vyyo.comConfiguration Overview – p. 23First, the modem searches for a signal at its preprogrammed DownstreamFrequency. Once having locked to that downstream channel, the modemreceives upstream channel descriptors (UCDs) from the WMTS that describe theavailable upstream channels.NOTE: The WMTS must be configured to construct theUCDs so that they correspond to the site preplan. Usethe Vyyo Configuration Tool to accomplish this if anychanges are required.The modem then enters a protocol exchange that requires data be transmittedfrom the modem to the WMTS via an Upstream Channel using its associatedChannel ID (designating the physical interface on the RF Interface card), and thecorrect frequency, modulation and bandwidth or symbol rate.NOTE: A modem configuration file which respecifiesthese parameters is downloaded to the modem after“ranging” (described below) is complete . This file is alsoreferred to as the modem “boot” file. All furthercommunication done by the modem uses the parametersspecified in this file. The modem configuration file ismodified using the CMconfigFileEditor tool.This protocol exchange allows the modem to ‘range’ (adjust its timing and powerlevel so that it can work successfully with all of the other modems on line at thistime.). After the ranging is finished, the modem has successfully establishedphysical layer and Link or MAC layer connectivity with the WMTS. The WMTS isnow capable of sending MAC layer packets such as DHCP and ARP requestsrequired to complete the registration process.2.4 IP LayerYour System Engineer must devise a Network IP Plan. This is required in orderto assign IP addresses to the WMTS and all the modems on the network. It mustinclude the IP address of all the servers as well as the network mask and othernetwork parameters.After connectivity is established at the DOCSIS layer (discussed in Section 2.3DOCSIS Layer ), the modem is assigned to an IP address by using DHCP(Dynamic Host Control Protocol.) If using the ipLease tool as the DHCP Server,this is usually a static IP address defined in the DHCP setup file (CM.SRC.) Thisfile binds the modem's MAC address to a particular fixed IP address. If usingWindows 2000 Server Edition this binding is accomplished using its DHCPAdministrative Tool, which may be installed at the user’s option using the “netsh”command (follow the instructions provided with your server).The DHCP server grants the “lease” on the IP address to the modem (i.e., tellsthe modem which IP address to use). The granted IP address is for SNMPconnectivity within the Vyyo system; it is not offered as a public IPaddress toVyyo equipment. However, if desired this can be done using the customer PC orRouter as the modem will behave as Layer 2 bridge device.
www.vyyo.comConfiguration Overview – p. 24For the ipLease DHCP Server tool, the CM.SRC file is an ASCII text file that maybe edited using any text editor (such as Notepad). This document describes theconfiguration process using the ipLease tool. The changes are similar for otherDHCP servers. Note that if another operating system, such as the Windows200x Server, is used a DHCP server is often included. Check with your Vyyorepresentative to make sure the DHCP server is compatible.NOTE: Before the modem can acquire an IP address, theWMTS must be configured with its own IP address Thisprocedure is described later in this document in thesection entitled Setting the WMTS IP Address. TheWMTS IP address is specified in a different configurationfile (regtree.rtr) which may be edited using theXmtsConfigurationFileEditor tool.After the modem successfully receives its IP address it contacts the TOD serverto establish the time of day. Next, it contacts the TFTP server to download themodem configuration file, which specifies the final DOCSIS parameters for themodem. This file is also referred to as the modem “boot” file. All furthercommunication done by the modem uses the parameters specified in this file.This file may cause the modem to change frequencies or reboot in order to resetsome of its configuration parameters. The modem will acquire this file every timeit is reset or restarted. Configuration changes to the modem configuration file(profile) will be done from the Operation center with out the need to visit themodem remote location for any setup change; These changes may includeencryption, QoS., IP filters, downstream channel parameters. etc….NOTE: the modem configuration file is modified using theCMconfigFileEditor tool..During the final phase of the DOCIS registration process, the modem sends aregistration message to the WMTS confirming that the configuration file wasreceived. The WMTS retrieves a copy of the configuration file from theconfiguration file server TFTP root repository directory. The WMTS thencompares the file from the server with the data from the modem to ensure thatthe modem will only use services for which it was authorized. The modem is thenfinally allowed to transmit real user data into the network, but only after themodem’s configuration file values are crosschecked by the WMTS.At this point, a data only modem will be successfully connected to the system.2.5 E1/T1 LayerAfter IP connectivity is established, E1 or T1 connectivity may be established.Note that in addition to installing an E1/T1 card into the WMTS chassis, E1 andT1 each require that different firmware be loaded into both the WMTS and themodem.The E1/T1 configuration will require appropriate changes to the modemconfiguration file in addition to setting those configuration parameters used for a
www.vyyo.comConfiguration Overview – p. 25standard IP-only modem. The same modem configuration file may be used forseveral modems provided the Downstream frequencies and the UpstreamChannel ID are the same (i.e., same “profiles”).The WMTS E1/T1 configuration needs to be modifed appropriately for everyE1/T1 modem installed on the network. This is done using the Java™-basedVyyo Configuration tool. This tool configures the E1/T1 port on the modem to beconnected (“bound’) to the correct E1/T1 port on the E1/T1 card plugged into theWMTS.After this tool is used to bind the E1/T1 ports together and the standard modemprovisioning is done, the installation is complete and the E1/T1 services in themodem are ready to be activated.

www.vyyo.comThe Modem Initialization Process – p. 28Chapter 3. The Modem InitializationProcessTo understand the configuration process, it is useful to understand thedetailed steps the modem goes through during its initialization.When the modem is first powered up, it must go through a fixed sequence ofsteps before it can exchange data with the network. To be successful, thisrequires the modem and the WMTS to be configured with variousparameters.These parameters should be defined in a Network RF Plan and a Network IPplan set up by your System Engineer. The three Network Servers (TOD,DHCP, and TFTP) must be installed and operational. The WMTS must beconfigured with the correct software and an IP address.The modem’s RF parameters must also be correctly configured with theproper software and its RF parameters must be set correctly. When all ofthis is done, the modem is ready to initialize itself when placed at thecustomer’s premise.Finally, after initialization, the modem’s E1/T1 port must be “bound” (configuredto connect) to the correct E1/T1 port on the WMTS. This step may be done lastor pre-configured before the modem is at the customer’s premise.The following sections provide an overview of the modem initialization process.3.1 Modem Initialization SequenceAll modems proceed through the following sequence of steps, each of whichis described in more detail below. The completion of these steps establishesconnectivity at the DOCSIS and IP layers. Connectivity for additional layers,e.g., E1/T1, may then be established for the V311 and V312 modems. Thesteps are:• Power-On Self Test• Downstream Synchronization• Obtain Upstream Parameters• Ranging• Establish IP Connectivity• Establish Time of Day• Transfer Operational Parameters• Registration• Baseline Privacy Initialization3.1.1 Power-On Self TestThe modem performs a self-check to ensure that its hardware is workingproperly.
www.vyyo.comThe Modem Initialization Process – p. 293.1.2 Downstream SynchronizationThe modem listens for downstream transmissions from the WMTS (whichare broadcast at frequent intervals for exactly this purpose) according to itspre-configured or default frequency plan. This may be a single fixedfrequency or a sequence of frequencies, depending on the Network RF Planand/or the internal programming of the modem.If the modem is programmed for a single fixed downstream frequency andfails to receive an WMTS downstream transmission after three attempts itswitches to its additional backup frequencies. See Setting the Modem’sDownstream Frequency for a description of how to set these parameters.Synchronization is obtained when the modem locks onto the WMTSdownstream signal and is able to recognize downstream SYNC messageswhich are periodically broadcast: these are crucial to calculating the timeslots available for upstream transmission.3.1.3 Obtaining Upstream ParametersThe modem must now wait to collect all the Upstream Channel Descriptors(UCDs) for all upstream channels that are connected to the currentdownstream channel.3.1.4 RangingThe modem then sends a “ranging request” message on one or more of theUpstream frequencies, corresponding to a UCD, at different power levels inan attempt to establish communication with the WMTS. Eventually theWMTS decodes a ranging request from the modem and sends a rangingresponse.Ranging is now complete. Whenever the modem needs to send MAC layerdata for IP to the WMTS it sends a “request” to the WMTS. The WMTSschedules a time slot for the modem and sends a “grant” message back tothe modem that contains all the necessary information telling the modemwhen it can transmit data. A similar method is used to send E1 or T1 dataexcept that the request sets up periodic time slots that the modem uses totransmit data.3.1.5 Establish IP ConnectivityThe modem uses the “request-grant” (“best effort”) mechanism to send astandard DHCP request to the Network DHCP server. The server willrecognize the modem via its MAC (Ethernet) address and assign it atemporary IP address. This response also contains the default gateway andthe IP subnet mask. The IP addresses of the TFTP and ToD servers, andthe name of the modem configuration file are also included. The responsealso includes the local time offset from Universal Coordinated Time (UTC).Once the modem receives this response it sets its IP address to thedesignated value and uses the default gateway to talk to devices using its IPstack.
www.vyyo.comThe Modem Initialization Process – p. 303.1.6 Establish Time of DayThe modem uses the ToD server address(es) just received to send a Time ofDay request to the ToD server(s). This is combined with the time offsetreceived in the DHCP response to calculate the current local time. The Timeof Day is used by both the modem and the WMTS to timestamp loggedevents (accessible via the Network Management System).3.1.7 Transfer Operational ParametersThe modem then requests the TFTP server to send the configuration ( or“boot”) file named in step (5) above during the establishment of IPconnectivity. If the boot file specifies a different upstream channel and/ordownstream frequency, the modem must repeat its initial ranging using thisnew upstream channel and/or downstream frequency.3.1.8 RegistrationIn order to forward traffic into the network the modem must be “registered”with the WMTS. To register, the modem sends the WMTS its class ofservice (also called QoS for Quality of Service) and any other operationalparameters it received in the configuration file as part of a RegistrationRequest. As part of the registration process the modem calculates MessageIntegrity Check (MIC) values using the parameters specified in itsconfiguration file. This must match the values given for those parameters inthe configuration file itself.3.1.9 Baseline Privacy Initialization (BPI)If the modem is enabled to run BPI then encryption and decryption keys areestablished. All further data to or from the modem is now encrypted. Thekeys have a lifetime and are automatically reset to new values after aspecified period which may be set by the operator using the NMS.NOTE: BPI is required in order to support E1/T1
www.vyyo.comOverview of the WMTS and Modem Configuration – p.31Chapter 4. Overview of the WMTSand Modem ConfigurationThis section provides an overview of the steps and tools necessary to configureboth sides of the communications link (WMTS and modem) required to add adata modem or the data portion of a new E1/T1 modem to the network. Severaldifferent tools and files are used as described below.1. Make sure that the three required servers are installed and operational:DHCP, ToD and TFTP. For details see Chapter 8, Installing VyyoServers for WMTS Operation. The failure of the modem to establishcommunication with any of these three servers will prevent the modemfrom completing the registration process.2. Review the Network IP Plan and use it to assign an IP address to theWMTS, then make it permanent by following the procedure in the sectionSetting the WMTS IP Address.3. Verify that the right software version is loaded into the WMTS asdescribed in Appendix B. See the “readme” notes in the distributionsoftware for the version number.4. Review the RF plan for the network and configure the WMTS upstreamand downstream channels accordingly using the procedures in Settingthe Upstream Channel. It may not be necessary to configure newupstream and downstream channels when adding a modem; but ifrequired, the Vyyo Configuration tool can be used to modify theseparameters.5. Review the RF Plan to find out which downstream frequency(ies) andupstream channel ID(s) the modem will use to communicate with theWMTS. Use the CMConfiguration Editor (CMConfigFileEditor.exe) toedit the modem configuration file that will be downloaded to the modemduring the modem initialization sequence to reflect these choices andother needed parameters (e.g., QoS or Class of Service, Max Number ofCPE, BPI Enable/Disable – required for E1/T1, etc.). If you know inadvance that this modem will be used for an E1/T1 connection thenadditional edits may be made at this time as described in Chapter 6,Configuring a T1 Connection.NOTE: One modem configuration file may be used forseveral modems if the same upstream channel ID anddownstream channel are used by all the modems (i.e.,same “profile”); thus, this step may not be required everytime a new modem is added to the system.
www.vyyo.comOverview of the WMTS and Modem Configuration – p.326. .NOTE 1: Five T1s per 3.2MHz upstream channel using16QAM modulation is the hard limit for the currentsystem. Attempting to configure more T1s on anupstream channel than it can support will cause themodem initialization to fail. Consult your system engineerfor advice on the maximum number of modems perupstream channel ID.7. Use the appropriate DHCP tool for your system to bind the modem’sMAC address to its IP address and modem configuration file. If ipLeaseis used, edit and compile the CM.SRC file as needed. If Windows 200xServer Edition is used then set these values using the graphical userinterface. These procedures are described in section 5.2.2, Windows200x Server Edition: Modifying the DHCP OptionsNOTE: this step is ALWAYS required when adding amodem8. Use the modem’s Telnet server interface to set the modem to apermanent downstream frequency as described in Setting the Modem’sDownstream Frequency. Having a permanent (fixed) downstreamfrequency (or set of frequencies) expedites the modem initializationprocess since the modem does not have to scan multiple downstreamfrequencies to find one being transmitted from the WMTS. This does,however, require some pre-planning of the network to pre-allocatedifferent downstream frequencies to specific modems. Ask your SystemEngineer for details.NOTE: this step is ALWAYS required when adding amodem with a fixed permanent downstream frequency9. If a T1 connection is being setup then use the procedures in Configuringa T1 Connection. Configure the WMTS upstream channel ID for E1/T1operation and bind the WMTS upstream channel ID to the modem E1/T1interface and to bind the modem’s E1/T1 interface to a particular port onthe E1/T1 card plugged into the WMTS (use the Vyyo Configuration toolfor this procedure.)NOTE: the Vyyo Configuration tool binding operation willALWAYS be required when adding a T1 modem. Thisstep can be done after the modem is installed at thecustomer’s site.10. Install the modem at the customer site and connect it to the RFequipment, provide power to the modem and turn it on.NOTE: This step is ALWAYS required when adding amodem
www.vyyo.comOverview of the WMTS and Modem Configuration – p.3311. If the modem is already on and its modem configuration file has beenchanged (to bind the E1/T1 ports), then the modem must be rebooted;although this happens automatically when the DHCP lease expires, it ismore efficient to simply power cycle the modem (unplug and replug thepower connector or switch the modem OFF then ON) to restart themodem initialization sequence.12. If desired, connect the modem’s internal Telnet server to a localcomputer system to observe the process on site and verify that themodem is working correctly.The POWER and STATUS LEDs should be lit and the LAN & USB, andRF Link LEDs should be flashing (one at a time) with activity:If the Power, Status, RF Link, and LAN/USB LEDs are lit, then the modemhas been successfully installed. If one or all of the lights remains unlit, seeChapter 9, Maintenance and Troubleshooting

DHCP Settings for the ModemSection 5.3 Configuring the WMTSdescribes how to configure the WMTS upstream, downstream and QoSparameters. This is done using the Vyyo Configuration Tool. Instructionsfor performing these changes are shown in Configuring the WMTS.4. Section 5.4 Setting the Modem’s Downstream Frequency describes howto set the modem downstream initial receive frequency via the modem’sinternal Telnet server.5. Section 5.5 Verifying the Modem Downstream and Upstream Statusdescribes how to use the modem’s internal Telnet server to view themodem’s downstream and upstream status (current values) and verifycorrect operation.5.1 Editing the Modem Configuration FileYou will need to edit the modem configuration file to set the WMTS downstreamfrequency, upstream channel ID, concatenation and fragmentation capabilities, andQoS. This file will be downloaded to the modem during its initialization sequence.NOTE: A separate modem configuration file is requiredfor each set of upstream and downstream channels. Anymodem may use any configuration file and the same filemay be used by many modems; typically only five T1modems are assigned to a single 3.2MHz upstreamchannel.5.1.1 Setting the Upstream ChannelOpen the CMConfigFileEditor to edit the modem configuration file to set theDownstream Frequency and Upstream Channel ID.Note: If using ipLease, the modem configuration file isbound to the modem’s MAC address in the CM.SRC file.If using Windows 200x Server Edition bring up the DHCPAdministrative Tool to find the configuration file to themode: Programs->Administrative Tools->DHCPFor more detailed information, see section 5.2.2,Windows 200x Server Edition: Modifying the DHCPOptionsFrom the main screen shown below select “General Parameters” and thenchoose “Upstream Channel ID”.
System Configuration Guidewww.vyyo.comAdding a Modem to the WMTS – p. 36Right-click on “Upstream Channel ID” and select “MODIFY” to display the popupwindow in which you may set the value of the Upstream Channel ID.Note: The detailed parameters for each upstreamchannel must be set in accordance (see Setting theUpstream Channel)with the overall Network RF Plan –contact your system engineer for assistance. TheChannel ID is the identifier for the physical RF port on theRF cards plugged into the rear of the WMTS. The portsare numbered as follows:Channel ID = card slot number + port numberWhere the card slot number is zero for the leftmostupstream card (as viewed from the front of the WMTS)and increases by the ifIndex of the card times eight foreach additional card. The if index of the card can befound in the ifTable. Please contact Vyyo for the exactdetails of this configuration. Typically, the ifIndexincreases from left to right by 1 for each card, from 0 to n,where n is the rightmost card. The ports are numberedfrom bottom to top on each card starting with one. Thus,the first card has ports numbered from 1 to 6 (since theHex upstream card only has six ports even though amaximum of 8 are allowed) and the second card has itsports numbered from 9 to 14, etc. Contact Vyyo forDetails.NOTE 2: See Setting the Upstream Channel to set thereceive frequency of an upstream channel.

SeeChapter 7. Setting the WMTS IP Address.This section assumes that you have previously installedNMS Version 7. See Installing and Uninstalling the NMSfor brief instructions.The upstream and downstream channels of the WMTS must be configuredbefore a modem can communicate with the WMTS. This is done using the VyyoConfiguration Tool. Before proceeding, launch the Vyyo Configuration Tool asdescribed in Launching the Vyyo Configuration Tool.5.3.1 Setting the WMTS Upstream Parameters1. Expand the WMTS tree in the left pane of the Vyyo Configuration Tooland select the Upstream Channel ID you wish to configure using themouse. The Channel ID refers to the physical port on the upstream RFcard that you are configuring. This connection is described in WMTS USPort Mapping. In this example upstream channel 1 is selected and all ofits parameters are displayed in the right pane of the window.You may change the frequency the modem is told by the WMTS totransmit on (labeled “Tx Frequency”), the receive frequency that theupstream RF port expects to receive the modem’s signal on (this islabeled “Rx frequency”), its bandwidth, modulation, and the associateddownstream channels, antenna diversity and admin status as needed.These parameters are transmitted by the WMTS as part of the upstreamchannel descriptor (UCD) sent during the DOCSIS modem initializationprocess. These parameters should be determined by the systemengineer responsible for the RF planning and are outside the scope ofthis manual.

System Configuration Guidewww.vyyo.comConfiguring a T1 Connection – p. 76Chapter 6. Configuring a T1ConnectionNOTE: the data connection for the E1/T1 modem mustbe setup as previously described in Chapter 5, Adding aModem to the WMTSThree separate tools are necessary to configure a T1 connection:The CMConfigFileEditor is used to set the modem QoS (also referred to as Class ofService) in the modem configuration file downloaded during the modem initializationphase.The NMS (Castlerock SNMPc) tool is the Network Management System used to monitorand reconfigure the network on an ongoing basis. It accesses a MIB database stored inthe WMTS as well as a local version residing in the controlling computer. It is used hereto set specific WMTS parameters by launching the Vyyo Configuration tool.The Java™-based Vyyo Configuration Tool is necessary to set the E1/T1 parametersof the WMTS when adding a new modem to the network.These tools may be used as directed in any order. They are described in thefollowing sequence:1. The CMConfigFileEditor is used to modify the modem configuration filefor T1 operation by adding a second Class of Service (the first Class ofService was used for the data only connection). Instructions are alsogiven for setting/checking the upstream and downstream parameters(which may have been previously set when configuring the modem fordata only operation).2. The NMS tool is used to launch the Vyyo Configuration Tool to set theWMTS upstream parameters, specifically the QoS (Quality of Service)which is another name for the Class of Service. For older systems,Instructions for using the Synoptics interface are given in Chapter 10,Error! Reference source not found..3. The Vyyo Configuration Tool is required to bind the T1 ports of themodem to the T1 ports of the WMTS.
System Configuration Guidewww.vyyo.comConfiguring a T1 Connection – p. 776.1 Configure the Modem for T1 OperationIn this section instructions are provided for using the CMConfigFile Editor to editthe modem configuration file which will be downloaded to the modem. When theedits on the following pages are complete, copy or move the modemconfiguration file to the directory being used by the TFTP Server (usually this willbe something like “C:\vyyo\mic”). You may also save it directly to the TFTPdirectory using the “Save” menu option of the CMConfigFile Editor.NOTE: This file name must be bound to this modem’sMAC address by using the appropriate DHCP tool for theparticular system being used (Edit the CM.SRC file ifipLease is being used. If the Windows 200x ServerEdition DHCP Administrative tool is being used then setthe “bpBootfile” name to the name of the modem’sconfiguration file).1. Set the Downstream Frequency by selecting “General Parameters” thendouble clicking on the “Downstream Frequency (Hz)” parameter asshown. This is the frequency which the modem will use to receive(downstream) transmissions from the WMTS. This procedure forconfiguring the downstream channels is described in Setting theDownstream Frequency.Figure 6-1: Set the Downstream Frequency Value
System Configuration Guidewww.vyyo.comConfiguring a T1 Connection – p. 784. Set the upstream channel ID using the same procedure. This is thechannel ID the modem will use to transmit upstream data to the WMTS.The channel ID parameters are sent by the WMTS when it broadcastsUCDs during the Obtaining Upstream Parameters phase (immediatelyafter the Downstream Synchronization phase) of the modem initializationprcocess. This procedure for configuring the downstream channels isdescribed in Setting the WMTS Upstream Parameters.Figure 6-2. Set the Upstream Channel ID

Vyyo Installation Guidewww.vyyo.comSetting the WMTS IP Address – p. 93Chapter 7. Setting the WMTS IPAddressNote: Prior to performing this procedure the WMTS mustbe connected to the “download” computer serial port viathe lower COM port (COM2) on the WMTS Control andForward card.The WMTS must also be connected to the same LANsubnet as the computer using its RJ45 connector on thesame (Control and Forward) card.Tip: The procedure used to download the Regtree file viathe LAN connection may also be used to download otherfiles to the WMTS, such as new versions of the software.First, the XmtsConfig.exe tool is used to set a temporary IP addressfor the WMTS. This IP address allows the WMTS to appear on theLAN subnet and communicate with the servers (which are on the samenetwork). The serial port connection is used to set the temporary IPaddress and the LAN connection is used to perform the actualdownload (via the temporary IP address previously set using the serialport connection). After the modified version of Regtree (containing thePERMANENT IP address of the WMTS) is downloaded and the WMTSis restarted, the WMTS will be accessible via its PERMANENT IPaddress.Next, we will be modifying regtree.txt to contain the permanent WMTSIP address, then compiling regtree.txt into regtree.rtr and downloadingit. The download is made by specifying regtree.rtr in the “Version File”field of the XmtsConfig.exe tool and making sure that regtree.rtr (thecompiled version of regtree.txt) is copied into the TFTP file transferfolder.1. Locate the file “regtree.txt” and open it using a standard text editor suchas Notepad (do not use the XmtsConfigFileEditor for this as it does notallow editing of the necessary entries). There may be several versions ofthe Regtree file available (e.g., “regtree_data.txt”, “regtree_t1.txt”, etc.)so ask your system engineer which one to use, then copy and rename itto “regtree.txt” since that is the file which SETIP.bat expects as its inputfile. Scroll down (or use the “Find” function from the menu) to the entry“CmtsIPAddress” which is shown as 10.10.10.210 in this example. Thedefault network address for Vyyo equipment is 10.10.10.xxx. Yoursystem engineer should be able to provide the following informationrequired to configure the WMTS:
Vyyo Installation Guidewww.vyyo.comSetting the WMTS IP Address – p. 94• WMTS IP address• Gateway computer (used for downloading) IP address• Gateway computer subnet mask• IP addresses of any other computers that are permitted toaccess the WMTS remotely2. Change the “CmtsIPAddress” as desired: this is the WMTS’spermanent IP address which will be downloaded later using theXmtsConfig tool.3. Change the two lines immediately following this line if necessary: the“GatewayIPAddress” (the address of the gateway computer or router)and the “CmtsSubnetMask”.4. Change DevNMAccessIP1 and DevNMAccessCommunity for remotecontrol as appropriate in Regtree.txt. Up to five IP addresses may bedefined here. The first one should be the same as that of the Gatewaycomputer or router used in the previous step. If you wish to addadditional remote computers: duplicate the three lines forDevNMAccessIP1 and DevNMAccessCommunity1 andDevNMAccessControl1 for each additional remote computer, changethe numbers so that you have DevNMAccessIP2,DevNMAccessCommunity2, DevNMAccessControl2 for the secondcomputer and so forth up to the fifth remote computer. Then change thecorresponding IP addresses for DevNMAccessIP2 and so forth.Note: No other edits should be necessary in this file,although the default frequencies for all the upstream anddownstream channels are initialized in this file and maybe changed if necessary.

Vyyo Installation Guidewww.vyyo.comWMTS US Port Mapping – p. 116Chapter 9. Maintenance andTroubleshooting9.1 IntroductionThe WMTS is an IP centric two-way RF system, which incorporates variousinformation technologies and RF devices. When the system is not operatingproperly, the malfunction must be isolated to localize the problem to a singlefunctional area.The troubleshooting process consists of three basic steps:• Identifying the problem,• Diagnosing the problem, and• Implementing a solution.To identify a problem, you have to ask two questions:1) When does the problem occur?2) What else is affected?For example, when none of the modems respond to an SNMP request, it can beassumed that the WMTS or the RF components at the base station are notfunctioning properly. Try to find out if the problem is on the downstream orupstream path. If only a certain modem does not respond, it can be assumedthat the problem relates to the subscriber site, or an NMS software setting forthat particular subscriber.If you have identified the problem, you are ready to diagnose its cause and takethe necessary actions to solve the problem.When implementing solutions, change one thing at a time, if possible. If the firstsolution does not solve the problem, reverse the change you just made and tryanother solution. For example, you are experiencing problems in one of theupstream sections. To solve the problem, replace the demodulator card. If theproblem still remains, replace the old card and try another solution.Some of the symptoms can be related to a certain functional area, some not.Use the system block diagram in the next section Troubleshooting the RFFrontend to relate the problem to a certain area.9.2 Troubleshooting the RF Frontend9.2.1 GeneralThe RF frontend contains the upstream and downstream channel converters andamplifiers.
Vyyo Installation Guidewww.vyyo.comWMTS US Port Mapping – p. 117Use a spectrum analyzer and RF power meter to perform tests.A typical basic RF setup is illustrated in Figure 9-1. Please use the specific blockdiagram for your system when you are troubleshooting problems9.2.2 Checking the DownstreamPerform the following steps to isolate a problem on the downstream channel of the RFfrontend:a. On the transmitter RF power meter -- Check the transmit power on the downstream transmitter, to verify the RF output- Test the reflected power (SWR), to verify that the transmitter is connected to thecoaxial system correctly.b. WMTS- Measure the output power of the demodulator card. Use a spectrum analyzer tuned to 44 MHz, with a span of 20 MHz. . The power should be 10 dBm ±5 dB.

Repairs of WMTS should take place only in VYYO company servicelaboratories or in other VYYO formally approved distributors service laboratories.In case of field handling our general SAFETY warning is to disconnect the unitfrom power supply for safest repair.2. In case of a -48VDC operated WMTS, the External Circuit Breaker(Du Pole) must be used before connection/removal of the power cable to/fromthe WMTS.

Appendix D. Launching the VyyoConfiguration ToolThe Vyyo Configuration Tool is used to configure the WMTS and there are two ways tolaunch the Vyyo Configuration Tool. You may use either one, depending on whether ornot the NMS (SNMPc) is up and running. If you just need to configure the WMTS it iseasier to launch the Vyyo Configuration Tool from the Windows “Start” menu. If you arealready working with the NMS you may launch the Vyyo Configuration Tool for aparticular WMTS on the network – there is a small advantage in doing this since you willnot have to add (“Insert”) the WMTS to the Vyyo Configuration Tool because the IPaddress of the WMTS is passed directly to it upon invocation.
