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: Througout this manual the terms modem andWMU are used interchangeably. The term “WMU” refersto “Wired/wireless Modem Unit”. In some instances theactual modem model (V280, V301, etc.) may be used ifthe information is specific to that modem. The term “XMTS” is used interchangeably with “WMTS”.XMTS is an acronymn for “Xtend Modem TerminationSystem” and will replace WMTS , “Wired/wireless ModemTermination System”.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 XMTS(Cable/Wireless Modem Termination System) end and a correspondingcable/wireless modem at the downstream end.InternetorPSTN Hybrid Fiber/Coax Cable NetworkCustomer PremisesXMTSCableModem(CM)CustomerEquipment
www.vyyo.comSystem Configuration Introduction – p. 11The 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 XMTS 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 LinkDOCSISXMTSModemIP, E1/T1, POTSRF LinkDOCSISLayer 3Layer 2Layer 1 RxTxV280 Modem100BaseTIP NetworkMTAPCLine #2FaxLine #1PhoneRJ-11RJ-11PSTNH.323v2 orMGCP, VOIPPacketVoiceServerE1/T1V311 E1/T1 ModemIP RouterProvisioningServicesXMTSInternetTelephoneSwitchPBXIntranetRF 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 XMTS.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 XMTS used at the head end is the other major component. There is only onebasic configuration, which is augmented with additional plug-in cards toaccommodate E1/T1 and PSTN capabilities.NOTE: The term XMTS was originally conceived as“extended” 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 XMTSThe basic XMTS 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. The E1/T1 capability is added by requires the Master4 card(which replaces the older HOST card), and adding one or two E1/T1 interfacecards in the rear slots to provide 12 or 24 E1/T1 ports, respectively.The HOST or Master4 card serves as the PCI bus arbiter and provides thesystem clock and timing. When the XMTS 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.All Universal cards are the physically identical: the card attached to them in therear slots and the application downloaded during initial startup determine thefunction of the card (Upstream, Downstream or Control & Forward).
www.vyyo.comSystem Configuration Introduction – p. 14In 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 XMTS Chassis with (from left to right) Upstream card, Downstreamcard, Control and Forward card, MASTER4 card, and Power Suppliesshown.The XMTS 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 requiredin 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.

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 XMTS 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 XMTS 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 XMTS 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.

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 XMTS 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 XMTS 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 XMTS.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 XMTS. 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 XMTS. It allowsthe XMTS 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 theXMTS and the modems. Each modem must be assigned to a specific XMTSUpstream Channel (the upstream channel is referenced by its Channel IDwhich identifies the physical port.) The Upstream channel must beconfigured for a specific frequency, modulation and bandwidth or symbolrate.NOTE: The XMTS 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 XMTS Downstream Frequency and the modem Downstream FrequencyThe XMTS 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 XMTS that describe theavailable upstream channels.NOTE: The XMTS must be configured to construct theUCDs so that they correspond to the site preplan. Usethe Vyyo Config Tool to accomplish this if any changesare required.The modem then enters a protocol exchange that requires data be transmittedfrom the modem to the XMTS 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 WMUconfigFileEditor tool. ( WMUstands for Wireless Modem Unit.)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 XMTS. The XMTS 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 XMTS 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, theXMTS must be configured with its own IP address Thisprocedure is described later in this document in thesection entitled Setting the XMTS IP Address. The XMTSIP address is specified in a different configuration file(regtree.rtr) which may be edited using thewmtsConfigurationFileEditor 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 theWMUconfigFileEditor tool..During the final phase of the DOCIS registration process, the modem sends aregistration message to the XMTS confirming that the configuration file wasreceived. The XMTS retrieves a copy of the configuration file from theconfiguration file server TFTP root repository directory. The XMTS 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 XMTS.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 XMTS chassis, E1 andT1 each require that different firmware be loaded into both the XMTS 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 XMTS 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 theXMTS.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 XMTS 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 XMTS must beconfigured with the correct software and an IP address.The modem’s RF parameters must also be correctly configured. The modemmust be configured with the correct software and its RF parameters must beset correctly. When all of this is done, the modem is ready to initialize itselfwhen placed at the customer’s premise.Finally, after initialization, the modem’s E1/T1 port must be “bound” (configuredto connect) to the correct E1/T1 port on the XMTS. 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 XMTS (which arebroadcast at frequent intervals for exactly this purpose) according to its pre-configured or default frequency plan. This may be a single fixed frequencyor a sequence of frequencies, depending on the Network RF Plan and/or theinternal programming of the modem.If the modem is programmed for a single fixed downstream frequency andfails to receive an XMTS 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 XMTSdownstream 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 XMTS. Eventually the XMTSdecodes a ranging request from the modem and sends a ranging response.Ranging is now complete. Whenever the modem needs to send MAC layerdata for IP to the XMTS it sends a “request” to the XMTS. The XMTSschedules 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 XMTS 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 XMTS. To register, the modem sends the XMTS its class of service(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 XMTS and Modem Configuration – p. 31Chapter 4. Overview of the XMTS andModem ConfigurationThis section provides an overview of the steps and tools necessary to configureboth sides of the communications link (XMTS and modem) required to add a datamodem 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 andoperational: DHCP, ToD and TFTP. For details see Chapter 8,Installing Vyyo Servers for XMTS Operation. The failure of themodem to establish communication with any of these three serverswill prevent the modem from completing the registration process.1. Review the Network IP Plan and use it to assign an IP address to theXMTS, then make it permanent by following the procedure in the sectionSetting the XMTS IP Address.2. Verify that the right software version is loaded into the XMTS asdescribed in Appendix B. See the “readme” notes in the distributionsoftware for the version number.3. Review the RF plan for the network and configure the XMTSupstream and downstream channels accordingly using the procedures inSetting the 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.4. Review the RF Plan to find out which downstream frequency(ies) andupstream channel ID(s) the modem will use to communicate with theXMTS. Use the WMUConfiguration Editor (wmuConfigFileEditor.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 XMTS and Modem Configuration – p. 325. .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.6. 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 amodem7. 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 XMTS. 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 frequency8. If a T1 connection is being setup then use the procedures inConfiguring a T1 Connection. Configure the XMTS upstream channel IDfor E1/T1 operation and bind the XMTS upstream channel ID to themodem E1/T1 interface and to bind the modem’s E1/T1 interface to aparticular port on the E1/T1 card plugged into the XMTS (use the VyyoConfiguration tool for 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.9. 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 XMTS and Modem Configuration – p. 3310. 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.11. 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:12. 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

Editing the Modem Configuration File describes the steps necessaryto setup the modem configuration file.
System Configuration Guidewww.vyyo.comAdding a Modem to the XMTS – p. 352. DHCP Settings for the Modem explains how to set (bind) themodem’s IP address and configuration file using either ipLease or theWindows 200x Server Edition DHCP Server.3. Configuring the XMTS describes how to configure the XMTSupstream, downstream and QoS parameters. At this time instructions areprovided for using the Vyyo Configuration tool. Older systems use theCastlerock NMS SNMPc Version 5 Synoptic display interface to changeXMTS parameters. Equivalent instructions for performing these changesare shown in Configuring the XMTS4. Setting the Modem’s Downstream FrequencySetting the Modem’sDownstream Frequency describes how to set the modem downstreaminitial receive frequency via the modem’s internal Telnet server.5. Maintenance and Troubleshooting describes how to use themodem’s internal Telnet server to view the modem’s downstream andupstream status (current values) and verify correct operation.5.1 Editing the Modem Configuration FileYou will need to edit the modem configuration file to set the XMTS 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 WMUconfigFileEditor 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,

TheChannel ID is the identifier for the physical RF port on theRF cards plugged into the rear of the XMTS. 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 XMTS)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.

System Configuration Guidewww.vyyo.comConfiguring a T1 Connection – p. 81Chapter 6. Configuring a T1ConnectionNOTE: the data connection for the E1/T1 modem mustbe setup as previously described in Chapter 5, Adding aModem to the XMTSThree separate tools are necessary to configure a T1 connection:The WMUconfigFileEditor 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 XMTS as well as a local version residing in the controlling computer. It is used hereto set specific XMTS parameters by launching the Vyyo Configuration tool.The Java™-based Vyyo Configuration Tool is necessary to set the E1/T1 parametersof the XMTS 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 WMUconfigFileEditor is used to modify the modemconfiguration file for T1 operation by adding a second Class of Service(the first Class of Service was used for the data only connection).Instructions are also given for setting/checking the upstream anddownstream parameters (which may have been previously set whenconfiguring the modem for data only operation).2. The NMS tool is used to launch the Vyyo Configuration Tool to set theXMTS 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,Synoptics Display for XMTS Configuration.3. The Vyyo Configuration Tool is required to bind the T1 ports of themodem to the T1 ports of the XMTS.
System Configuration Guidewww.vyyo.comConfiguring a T1 Connection – p. 826.1 Configure the Modem for T1 OperationIn this section instructions are provided for using the WMUconfigFile Editor toedit the modem configuration file which will be downloaded to the modem. Whenthe edits 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 WMUconfigFile 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”then double clicking on the “Downstream Frequency (Hz)” parameter asshown. This is the frequency which the modem will use to receive(downstream) transmissions from the XMTS. This is the same proceduredescribed in Setting the Downstream Frequency and is repeated here forconvenience.Figure 6-1: Set the Downstream Frequency Value

System Configuration Guidewww.vyyo.comConfiguring a T1 Connection – p. 842. Set the upstream channel ID using the same procedure. This is thechannel ID the modem will use to transmit upstream data to the XMTS.The channel ID parameters are sent by the XMTS when it broadcastsUCDs during the Obtaining Upstream Parameters phase (immediatelyafter the Downstream Synchronization phase) of the modem initializationprcocess. This is the same procedure described in Setting the XMTSUpstream Parameters and is repeated here for convenience.Figure 6-2. Set the Upstream Channel ID

Vyyo Installation Guidewww.vyyo.comSetting the XMTS IP Address – p. 102Chapter 7. Setting the XMTS IPAddressNote: Prior to performing this procedure the XMTS mustbe connected to the “download” computer serial port viathe lower COM port (COM2) on the XMTS Control andForward card.The XMTS must also be connected to the same LANsubnet as the computer using its RJ45 connector on thesame card.Tip: This procedure may also be used to download otherfiles to the XMTS, such as software downloads.The wmtsConfig.exe tool is used to set a temporary IP address forthe XMTS. This IP address allows the XMTS to appear on the LANsubnet and communicate with the servers (which are on the samenetwork).Next, we will be modifying regtree.txt to contain the permanent XMTSIP 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 wmtsConfig.exe tool and making sure that regtree.rtr iscopied into the TFTP file transfer folder.14. Locate the file “regtree.txt” and open it using a standard text editorsuch as Notepad. Scroll down (or use the “Find” function from the menu)to the entry “CmtsIPAddress” which is shown as 10.10.10.210 in thisexample. The default network address for Vyyo equipment is10.10.10.xxx. Your system engineer should be able to provide theaddresses and other parameters you need to configure the XMTS.15. Change the “CmtsIPAddress” as desired: this is the XMTS’spermanent IP address which will be downloaded in the next step.16. Change the two lines immediately following this line if necessary: the“GatewayIPAddress” (the address of the gateway computer or router)and the “CmtsSubnetMask”.17. Change DevNMAccessIP1 and DevNMAccessCommunity forremote control as appropriate in Regtree.txt. Up to five IP addresses maybe defined here. If you wish to add additional remote computers:duplicate the three lines for DevNMAccessIP1 andDevNMAccessCommunity1 and DevNMAccessControl1 for eachadditional remote computer, change the numbers so that you haveDevNMAccessIP2, DevNMAccessCommunity2,
Vyyo Installation Guidewww.vyyo.comSetting the XMTS IP Address – p. 103DevNMAccessControl2 for the second computer and so forth up to thefifth remote computer. Then change the corresponding IP addresses forDevNMAccessIP2 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.Figure 7-1. Regtree.txt File Contents
Vyyo Installation Guidewww.vyyo.comSetting the XMTS IP Address – p. 10418. Now compile regtree.txt by executing SETIP.bat which should be inthe same directory as regtree.txt.

Vyyo Installation Guidewww.vyyo.comMaintenance and Troubleshooting – p. 122Chapter 9. Maintenance andTroubleshooting9.1 IntroductionThe XMTS 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, andImplementing 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 thesystem block diagram in the next section Troubleshooting the RF Frontend to relate theproblem to a certain area.9.2 Troubleshooting the RF Frontend9.2.1 GeneralThe RF frontend contains the upstream and downstream channel converters andamplifiers.

Synoptics Display forXMTS ConfigurationThis chapter explains how to use the older Synoptics Display interface to set upstreamand downstream parameters for the xTMS.NOTE: Before you can perform this procedure you musthave previously edited the regtree.txt file, compiled it anddownloaded it to the XMTS. See Setting the XMTS IPAddress.This procedure is to be used only if you cannot configurethe XMTS using the Vyyo Configuration tool as describedin 5.3 Configuring the XMTS.11.1 Setting the XMTS Upstream Parameters1. Open the Network Management System and double-click on the XMTSicon to bring up the Network display of the XMTS front panel:
Vyyo Installation Guidewww.vyyo.comSynoptics Display for XMTS Configuration – p. 129Figure 11-1: Network display of the XMTS2. Now select the Upstream Channel ID you wish to configure and right-clickthe mouse. This is a “Synoptics” display of the actual front panel of theXMTS. Observe that there is only one (Hex) upstream card in thisexample: There are six ports, each one having its own unique upstreamchannel ID. In this example the channel IDs are the same as the portnumber. However, if a second Hex card were installed its channel IDswould be numbered from 9 to 14 and they would correspond to ports 1through 6 on the second card – note that this allows for 8 channel IDs perHex card even though only 6 are actually used.Double click this icon

Vyyo Installation Guidewww.vyyo.comSynoptics Display for XMTS Configuration – p. 1324. Using this popup window, you may change the frequency the modem isexpected to transmit on (labelled “Frequency”), the receive frequency thatthe upstream RF port expects to receive the modem’s signal on (this islabelled “Rx frequency”), its modulation, symbol rate and the associateddownstream channel, antenna diversity and admin status as needed.These parameters are transmitted by the XMTS 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.Figure 11-4: Upstream Channel ParametersSet this to ‘up” to operate thischannel or “down” to turn it offThe modem transmits on this frequencyLink LayerDOCSIS parametersRF DOCSIS parametersThis XMTS upstream channel is set toreceive on this frequencyThis is the XMTS downstream channelassociated with this XMTS upstreamchannelCheck this box unless your SystemEngineer indicates otherwiseCheck this box and click on “OK” tosave these upstream parameterspermanently in the XMTS memory

Click on the “QoS” tab to display the Quality of Service screen and checkthe appropriate QoS box. “Best effort channel” or “CIR channel” aretypically used for a data-only modem. An “E1 channel” must be usedwhen the modem supports E1/T1 connections and data. These settingscorrespond to the desired SLA (Service Level Agreement).6. The “Tx backoff” settings control the scheduling algorithms used in theupstream channel. The default values should be used unless yoursystem engineer has indicated otherwise.7. Ensure that the “Optimize channel parameters” box is checked. Thiscauses the XMTS to maximize the efficiency of the channel usage for thedifferent types of modems assigned to it. Check the “Save WMTSconfiguration” box and click on the “OK” button to permanentlyreconfigure the XMTS with these settings.Note: This box is used for both E1 and T1 connections.Figure 11-5: Editing QoS for Upstream ChannelCheck this box unless your SystemEngineer indicates otherwise
