For true end-to-end testing, service providers can use Tech-X Plus to test from the customerﾒs media gateway to the DSLAM and then on to the ATM/Ethernet backbone; and then to the Internet, voice, or video service provider.
Tech-X Plusﾒ expert copper, DSL, and IP diagnostics eliminate the need for a technician to be expert at new technologies. Tech-X Plus diagnostics automatically indicate the source of the problem and in plain English suggest the next steps.
By using one of the numerous connection options with test automation, the field technician quickly gains access to central office support and network resources during installation or troubleshooting.
Thorough testing of the end-usersﾒ voice, video, and data service reduces the customerﾒs wait between the service order initiation and service availability. In addition, if service interruptions occur, the resolution time is drastically reduced. With Tech-X Plus, service providers can confidently increase broadband IP service availability while attracting and retaining satisfied customers.
Comprehensive Copper Fault Analysis
Using the Multimeter (DVOM) features in Tech-X Plus, technicians easily identify AC and DC faults shown by large screen results and help menus. Tests for voltage, current, capacitance (opens), resistance, and balance identify the presence of these faults. After faults are shown to exist, the Tech-X Plusﾒ precise, long-range TDR finds the location of those faults with a simple push of a button. In addition, high-resistive faults can be found using the instrumentﾒs unmatched RFL feature.
DSL Pre-qualification
The Tech-X Plus locates all types of faults. It is equipped with wideband noise and loss tests that provide qualitative testing and impairment diagnosis for pre-qualifying the loop before deployment of xDSL services. Furthermore, wideband Power Spectral Density (PSD) can be used to identify noise disturbers and is shown on a large graphical screen.
DSL and IP Service Installation
In addition to copper qualification measurements, Tech-X Plus performs complete DSL service testing. Using a combination of modem emulation, DSL expert diagnostics, and various ATM/IP tests such as Ping, TraceRoute and even a Web Browser, Tech-X Plus helps your technicians verify that your customerﾒs service is working. Plain text and graphical results enable isolation of in-home wiring, local loop faults, noise disturbers, bad or missing DSLAM cards, and mis-configured port configurations.
Key Product Features
Automated Test Scripts
Tech-X Plus provides one-button test scripts tailored to service-specific Methods and Procedures (M&Ps). These scripts provide a quick indication that all required measurements have been made and that service levels have been met. As tests are performed, the user is automatically informed whether the results pass or fail pre-defined thresholds. These thresholds can be customized by a manager. This process standardizes testing and offers technicians the highest degree of confidence the service works properly and additional dispatches are not required.
Data Storage
All test results can be stored on the Tech-X Plus using a timestamp, a unique name and other pertinent information. Field supervisors can automatically receive collected results that provide a real-time assessment of crew progress. If results do not pass thresholds, the supervisor can be immediately notified. These results also identify technicians who are not consistently following M&Ps or who may need additional training. Such trending information is also valuable for plant engineering and planning.
Expert Analysis
The Tech-X Plus employs Spirentﾒs automated expert diagnostics to accelerate troubleshooting in the field. By pressing a single button, an automated test is performed, and its results are immediately analyzed and correlated to identify faults. The faults are prioritized according to the greatest impact on service. For field technicians, guesswork is removed from testing. Quick isolation and repair of faults is ensured.
Applications
xDSL Modem Emulation
Tech-X Plus emulates the xTU-R, enabling field technicians to separate network issues from in-house problems. The instrument emulates the xTU-R (customer modem) and trains with the DSLAM in the central office or remote terminal. By training with the DSLAM, results such as upstream/downstream rates, noise margin and errors are provided. Graphical results such as bits/bin and noise/bin are easily viewable on a large screen.
The Tech-X has a single onboard modem that emulates ADSL, ADSL2, and ADSL2+. This removes the need for multiple plug-in modules to be carried by the field technician which can end up damaged or lost.
DSL Expert Diagnostics
ADSL 2/2+ standards provide Management Information Bases (MIBs) for service technicians to obtain expert diagnostics on the source of low data rates. This can be done without interpreting hundreds of individual results. Using the DSL Expert Diagnostics option, a technician receives a report indicating disturbers such as bridged taps, missing micro filters, WB noise (e.g., T1, HDSL) and how they directly impact the data rate. Results are provided in plain text.
This option guides troubleshooting activities. The field technician avoids wasting time on problems that do not impact the data rate, thereby minimizing MTTR. The Tech-X Plus diagnostics option eliminates the need for each dispatched technician to be an expert at these new technologies. Fault isolation is quickly and reliably performed.
IP Video Testing
The Tech-X Plus provides field technicians with a comprehensive, yet easy to use tool for diagnosing problems with IPTV deployments. One button testing provides the user with a quick indication as to the Quality of Experience as received by the user. This measurement is a VMOS score, which is a numeric value between 1 and 5 that is used as a rating of the TV picture as seen by the customer. Should a more detailed analysis be required, measurements such as jitter, delay and packet loss can all be performed.
IP/ATM Testing
Once the xDSL link has been activated, the customerﾒs data, voice, and video services must be verified with various IP and ATM measurements. The field technician should attempt to verify connectivity to the Internet service provider (ISP) using various IP measurements such as an IP ping. By using a URL in a ping or trace route test, the technician is assured the customer can reach the desired IP address and that the domain name server (DNS) works properly. Tests such as a TraceRoute identify where excessive delay is introduced or how far the customerﾒs traffic can traverse the network before a failure. By using Tech-X Plus features, the technician verifies without entering the customerﾒs home, thereby decreasing time at each job.
Web Browser
The Web browsing feature further enhances the field technicianﾒs ability to verify DNS operation and can also be used to provide a fast, visual confirmation to the customer that their service is fully operational and thereby eliminates the need for the field technicianﾒs laptop to be carried in the field.
Key Copper Features
Multimeter (DVOM)
Voltage, current, resistance, and capacitance (opens) measurements can be performed to determine loop length, capacitive and resistive balance, current and battery voltage. Furthermore, the Tech-X Plus identifies faults such as opens, shorts, battery crosses, bad splices, and more.
Time Domain Reflectometer
Tech-X Plus provides an extremely highprecision TDR so that load coils, bridged taps and faults can be found with ease. Fully functional and simple to operate, this TDR reduces time spent trying to locate the fault. Other TDR highlights include:
- Large graphical display for easy fault finding and analysis
- Isolation of faults 26,000ft (8km) away
- Auto detection of faults such as opens, short, bridgetaps, and more
Resistive Fault Locator (RFL)
RFL analysis is used for high-resistance faults that normally cannot be found by a TDR. Loop resistance, insulation resistance, and accurate location of ground and battery faults are easily found with a touch of a button.
Wideband Services Testing
DSL and other digital services require the loop be pre-qualified before service is installed. The Tech-X Plus performs wideband (WB) insertion loss up to 12MHz for comprehensive loss characterization of the copper pair. In addition, the Power Spectral Density feature automatically identifies noise disturbers of DSL service such as HDSL, T1 and others. These higher bandwidths are important for qualifying services such as ADSL 2+, VDSL and VDSL2, which far exceed the 1.1MHz spectrum covered by traditional ADSL testers. Graphical and numerical analyses of noise in WB frequencies quickly isolate and resolve trouble associated with intermittent modem sync and/or data rate. Lastly, a WB longitudinal balance measurement is available for stressing the copper pair at DSL frequencies to verify the noise immunity of the pair.
Installation of Voice Services
Various features such as drawing dial-tone, C-Message noise, VF loss and DVOM tests enable field technicians to ensure the voice (e.g. POTS) service meets service criteria after the copper pair has been conditioned. Various test numbers such as quiet termination, milliwatt and ﾓdrop batteryﾔ can be stored in the unit for automatic dialling before the measurement is made. Using the built-in speaker, the field technician can listen to various tones being received.
In-Band Controllable Remote Unit
The Tech-X Plus has an optional remote unit, simplifying field testing of wideband insertion loss measurements. Once placed on the correct pair, the remote unit reduces truck rolls and time consumed waiting for other technicians to complete a job. This unit can be remotely configured via the line under test and DTMF tones to perform various measurements. For example, the remote unit can be instructed to send wideband tones for the Tech-X Plus to receive. Lastly, once the trouble has been fixed, the field technician remotely configures a through mode and immediately places the customer back in service.
The Remote Unit also operates as a far end strap when running the RFL test. The Tech-X Plus will automatically command the Remote Unit to open and short the pair as necessary in order to obtain the required measurements. This cuts down on the number of journeys that must be made to the far end of the pair which are normally required when using a manual strap.
