Page 84 Chapter 4 xDSL / G.fast Testing Specifying DSL / G.fast settings After selecting the test mode, if you have not loaded a previously defined test profile, you must specify DSL, and if applicable, G.fast settings to match the settings of the line that you are testing.
Page 85 Chapter 4 xDSL / G.fast Testing NOTE: Vectoring is only available for VDSL circuits. Vectoring technology is used on VDSL2 connections to reduce FEXT from other pairs in a binder group resulting in higher downstream and upstream rates for all the pairs in the group. Vector Friendly mode is suggested when there is a need to emulate CPE that is incapable of full vectoring, but has been designed to synchronize to a vectoring DSLAM without losing...
Page 86 Chapter 4 xDSL / G.fast Testing NOTE: Enabling DSL retransmission (adding the check mark) only advertises support to the DSLAM. It does not guarantee the connection will use DSL Retransmission (G.INP) because G.INP is specified in the CO configuration. DSL retransmission is required for G.fast testing; therefore, if G.fast is selected as the xDSL technology, retransmission is automatically enabled and cannot be configured.

Page 102 The server needs to be placed in the network in a way that will allow it to deliver very high data rate traffic to the ONX for downstream and upstream throughput testing. Viavi recommends the Apache HTTP server (v 2.4) that is readily available from Apache and supports multiple operating systems.
Page 103 Chapter 5 Data Testing 1. Once the server configuration is complete, the IP address of the server and filename of the throughput file must be configured in the ONX meter. Speed Check configuration is accessible from within the Speed Check screen. Press the Speed Check icon to enter Speed Check or use the arrows to highlight and select it, as shown here.

Page 105 Chapter 5 Data Testing Server scaling When configured as recommended above, one server can support multiple simultaneous ONX Speed Check tests. The scaling of this server should be based on two aspects: 1. First, the network connection to the server must be capable of supplying data rates necessary to support the number of concurrent tests.
Page 106: Before You Begin
Chapter 5 Data Testing Speedtest by Ookla data testing Speedtest is used to test servers all over the world. It determines the server name and checks downstream and upstream throughput via Ethernet or xDSL/G.fast test interfaces. Its download/upload rate is up to 1 Gbps for Ethernet TE. Speedtest uses any IP interface, including IPv4, that you established for testing.
Page 107: Server Settings
Chapter 5 Data Testing Server Settings The Server Settings screen for Speedtest provides the selection of either automatic or user- specified server for the test. • Select the Auto Server checkbox for the automatic server. The ONX will connect to a default Ookla server in the network, which will select the nearest Speedtest server, and use it for the remainder of the test.
Page 108: Latency Measurement
Chapter 5 Data Testing Running Speedtest Press the Start button on the Speedtest screen. As the test progresses, its current state is displayed. A green progress bar is presented when the state takes more than four seconds. An activity spinner indicates that the test is still running. Latency Measurement The ONX will ping the Speedtest server the number of times specified in the Speedtest configuration.

As the test runs, the speedometer moves to indicate the measurement, and the dial turns dark blue as it measures the speed.
Page 113 Chapter 5 Data Testing Average Latency Measurements The application sends UDP packets to the Broadcom Speed Service server, providing the timestamp of transmission. The server will use this timestamp and the timestamp at which the packet was received to calculate the average latency. Rate Measurements The ONX opens a TCP connection to the provided server, through which control packets are exchanged.

Page 176 Chapter 12 Testing Full Sweep Coax Coax Check Full Sweep Coax Check is similar to the Whole Home Check (No Diplexer) application we discussed in the previous chapter, with a few key differences. Firstly, the frequency sweep is conducted between 2 MHz and 1.6 GHz, unlike the Whole Home Check application that sweeps from 2MHz to 52MHz.
Page 177 Chapter 12 Testing Full Sweep Coax There are no pass/fail limits in the frequency sweep (RG-STB, STB-STB, and maximum delta limits between frequency bins of 4, 8 and 12MHz wide). Therefore, the Sweep Loss result card in the Test Summary page is white. However, Cable Faults and Ingress pass/marginal/fail limits have been preserved, similar to the Whole Home Check application.
Page 178 Chapter 12 Testing Full Sweep Coax The naming convention for splitters in the network has been updated in Coax Check.

Page 271: Longitudinal Balance
Chapter 15 Test Results Longitudinal balance You measure longitudinal balance to measure the quality of the pair – a measurement of the degree to which the Tip (A) lead is electrically the same as the Ring (B) lead. The more each lead is electrically identical (capacitance, inductance, impedance), the better the pair will resist induced noise.
Page 272: Impulse Noise
Chapter 15 Test Results A TDR (Time Domain Reflectometer) is used to identify and locate buried splices, shorts and low resistance faults, opens, bridge taps, load coils, and wet cables. Velocity of Propagation (VoP) is the speed of the TDR signal traveling down the wire pair relative to the speed of light.
