Chapter 1. System Configuration Introduction This guide is intended as a practical aid for the Technicians, Operators and Field Service Engineers responsible for quickly configuring Vyyo systems at most common installations. It is not intended as a substitute for a detailed reference manual. NOTE: Througout this manual the terms modem and WMU are used interchangeably. The term “WMU” refers to “Wired/wireless Modem Unit”. In some instances the actual modem model (V280, V301, etc.
The data from the IP, E1/T1, or PSTN layer are encapsulated as DOCSIS frames which 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 each layer, beginning with the lowest (RF link) in order to establish full communication. www.vyyo.com System Configuration Introduction – p.
The following diagram illustrates this in the form of a three layer protocol stack: XMTS Modem IP, E1/T1, POTS Layer 3 IP, E1/T1, POTS DOCSIS Layer 2 DOCSIS RF Link Layer 1 RF Link This illustration shows how a complete system is connected: Provisioning Services Tx PC Internet 100BaseT 100BaseT RF Cloud or Cable Plant Rx MTA XMTS V280 Modem RF Coax IP Network Packet Voice Server H.
There are different configuration requirements for each layer and different software tools accomplish this task. The configuration of the RF link is typically unique to each installation with the particular downstream and upstream frequencies, modulations and bandwidths being the critical parameters that must be set on the modem and XMTS. Whereas there is no set standard for implementing an RF link, DOCSIS is a fully specified protocol as are the upper layers (IP, E1/T1 or PSTN).
In the rear slots, one Downstream and one Upstream RF interface card are required. Each of these corresponds to its companion Universal card. The “Quad” downstream card has four RF connectors and provides four downstream channels. The “Hex” upstream card has six RF connectors and provides six upstream channels. Note: All Downstream cards have a fixed output frequency of 44 MHz which must be converted up per the local requirements.
Figure 1-2. Midplane Cutaway View of XMTS; Universal Card Shown in Cutaway attached to an RF card. www.vyyo.com System Configuration Introduction – p.
1.4 Modems 1.4.1 Modems with DOCSIS and IP only The 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. The V280 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 Support for updates as they become available if you need this capability. Figure 1-3.
1.4.2 Modems with DOCSIS, IP and E1/T1 The V311 is a V280 modem (to provide the DOCSIS layer) with one E1/T1 interface (via an RJ45 connector on the front panel) added. In addition to IP connectivity, it supports circuit switched E1/T1 applications. It has one 100 BASE-T port for IP data and one E1/T1 port which can support up to 32/24 time slots. The E1/T1 application supports framed or unframed E1/T1 services.
The 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 (plugged into the rear slots, with the second E1/T1 card attached to the first one as a daughter board) to work with the V311 or V312. The E1/T1 connection will be terminated 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.
1.4.4 Modems with DOCSIS and IP Only With Built in UHF Radio The V284 modem is a basic V280 modem integrated with a built-in UHF radio that provides an upstream RF output in the 710-716 MHz range. Internally the V284 has a factory set intermediate frequency of 44MHz which is converted up to yield an appropriate upstream frequency (This is preset at the factory for 700MHz in the United States). The downstream frequency ranges from 740-746MHz.

Chapter 2. Configuration Overview This section of the System Configuration Guide features a short overview of each component/layer of the System including the XMTS and the modems. The last section is a summary presented as a matrix that shows the relationships between the various tools and files. The components and layers are described below. • Network Servers o DHCP Server o TFTP Server o Time of Day (ToD) Server • RF Link Layer • DOCSIS Layer 2.
Your System Engineer must develop a detailed system plan that accounts for each of these variables. This plan must include the assignments of downstream frequencies, modulations (and other RF parameters) and upstream channel IDs assigned to the various modems deployed in the network.
First, the modem searches for a signal at its preprogrammed Downstream Frequency. Once having locked to that downstream channel, the modem receives upstream channel descriptors (UCDs) from the XMTS that describe the available upstream channels. NOTE: The XMTS must be configured to construct the UCDs so that they correspond to the site preplan. Use the Vyyo Config Tool to accomplish this if any changes are required.
For the ipLease DHCP Server tool, the CM.SRC file is an ASCII text file that may be edited using any text editor (such as Notepad). This document describes the configuration process using the ipLease tool. The changes are similar for other DHCP servers. Note that if another operating system, such as the Windows 200x Server, is used a DHCP server is often included. Check with your Vyyo representative to make sure the DHCP server is compatible.
standard IP-only modem. The same modem configuration file may be used for several modems provided the Downstream frequencies and the Upstream Channel ID are the same (i.e., same “profiles”). The XMTS E1/T1 configuration needs to be modifed appropriately for every E1/T1 modem installed on the network. This is done using the Java™-based Vyyo Configuration tool. This tool configures the E1/T1 port on the modem to be connected (“bound’) to the correct E1/T1 port on the E1/T1 card plugged into the XMTS.
2.6 Configuration Tools and Files Matrix Tool Configured File or Device Description WMUConfigurationFileEditor Modem Configuration file (e.g., “MIC_xxx.cfg”, where xxx is some unique number.) This file downloads to a modem during the registration process. It contains all the parameters required for the modem’s operation in the DOCSIS network: upstream and downstream frequencies, QoS, etc. It is also call the modem “boot” file. WMTSConfigurationFileEditor Regtree.txt Regtree.
Tool Configured File or Device Description NMS (Castlerock) XMTS or Modem MIB values (Typically for viewing only.) A general purpose Network Management System for operating the network; also used to launch the Vyyo Configuration tool to configure and change XMTS parameters. Any ASCII text editor, e.g., Notepad CM.
Chapter 3. The Modem Initialization Process To understand the configuration process, it is useful to understand the detailed steps the modem goes through during its initialization. When the modem is first powered up, it must go through a fixed sequence of steps before it can exchange data with the network. To be successful, this requires the modem and the XMTS to be configured with various parameters.
3.1.2 Downstream Synchronization The modem listens for downstream transmissions from the XMTS (which are broadcast at frequent intervals for exactly this purpose) according to its preconfigured or default frequency plan. This may be a single fixed frequency or a sequence of frequencies, depending on the Network RF Plan and/or the internal programming of the modem.
3.1.6 Establish Time of Day The modem uses the ToD server address(es) just received to send a Time of Day request to the ToD server(s). This is combined with the time offset received in the DHCP response to calculate the current local time. The Time of Day is used by both the modem and the XMTS to timestamp logged events (accessible via the Network Management System). 3.1.
Chapter 4. Overview of the XMTS and Modem Configuration This section provides an overview of the steps and tools necessary to configure both sides of the communications link (XMTS and modem) required to add a data modem or the data portion of a new E1/T1 modem to the network. Several different 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 Vyyo Servers for XMTS Operation.
5. . NOTE 1: Five T1s per 3.2MHz upstream channel using 16QAM modulation is the hard limit for the current system. Attempting to configure more T1s on an upstream channel than it can support will cause the modem initialization to fail. Consult your system engineer for advice on the maximum number of modems per upstream channel ID. 6. Use the appropriate DHCP tool for your system to bind the modem’s MAC address to its IP address and modem configuration file. If ipLease is used, edit and compile the CM.
10. If the modem is already on and its modem configuration file has been changed (to bind the E1/T1 ports), then the modem must be rebooted; although this happens automatically when the DHCP lease expires, it is more efficient to simply power cycle the modem (unplug and replug the power connector or switch the modem OFF then ON) to restart the modem initialization sequence. 11.
Chapter 5. Adding a Modem to the XMTS NOTE: These instructions are required for all modems. If you are adding a T1 modem then you must also perform the step in Chapter 6, Configuring a T1 Connection to finish the installation. Use the instructions in this chapter to setup a data modem or the data portion of an E1/T1 modem and configure the XMTS to communicate with it over IP. This chapter covers the following topics: 1. www.vyyo.
System Configuration Guide 2. DHCP Settings for the Modem explains how to set (bind) the modem’s IP address and configuration file using either ipLease or the Windows 200x Server Edition DHCP Server. 3. Configuring the XMTS describes how to configure the XMTS upstream, downstream and QoS parameters. At this time instructions are provided for using the Vyyo Configuration tool. Older systems use the Castlerock NMS SNMPc Version 5 Synoptic display interface to change XMTS parameters.

Vyyo Installation Guide Chapter 9. Maintenance and Troubleshooting 9.1 Introduction The XMTS is an IP centric two-way RF system, which incorporates various information technologies and RF devices. When the system is not operating properly, the malfunction must be isolated to localize the problem to a single functional area. The troubleshooting process consists of three basic steps: Identifying the problem, Diagnosing the problem, and Implementing a solution.
Vyyo Installation Guide Use 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 block diagram for your system when you are troubleshooting problems 9.2.2 Checking the Downstream Perform the following steps to isolate a problem on the downstream channel of the RF frontend: a.
Vyyo Installation Guide 9.2.3 Checking the Upstream Perform the following to isolate a problem on the upstream channel of the RF frontend: Measure the output power of the downconverter. Use a spectrum analyzer tuned to the upstream channel IF (about 44 MHz), with a span of 20 MHz. The following diagram illustrates a basic RF test setup.
Vyyo Installation Guide Chapter 10. Troubleshooting The Subscriber Site 10.1 Post-Registration Verification When the modem registration process has reached completion, connect the Laptop or PC to the V280 WMU and verify the following items: Verification Item Task 1 Check the IP address. From the Windows Command Prompt, ipconfig or winipcfg to view the configuration. Open the Web Browser and verify that there is proper Internet access. 2 Perform relevant system speed verification tests.
Vyyo Installation Guide Use the following steps to troubleshoot the RF layer: Verification Item Task Signal amplitude Connect the SLM to the IF input cable. Set the SLM to the appropriate known DS frequency and measure the amplitude in dBmV. Verify that the peak amplitude of the IF signal is compliant with the WMU input signal level specification. If no signal is present, verify that the radio transceiver was installed according to the manufacturer’s installation procedures.
