FaultMapper utilizes time-domain reflectometry (TDR) and frequency-domain reflectometry (FDR) technology to provide the additional capability of identifying the location of service affecting line faults including bridged taps, shorts, grounds and opens. EXFO’s unique SmartR presents results in an easy-to-understand, graphical format, making copper troubleshooting easier than ever before.
Key DSL Applications
- Ensures that the customer has the required bandwidth (downstream and upstream rates) for delivering triple-play services over single-pair or bonded ADSL2+ and VDSL2
- Validates that the IPTV and data services can operate on the circuit with the required QoS
- Verifies that the customer’s modem/router, equipment and inside wiring are operating correctly
- Proves data flow between the network and end equipment
Key Copper Applications
- Detection of potential bottlenecks on subscriber loops to ensure high-quality, consistent and error-free multiplay services
- 30 MHz spectrum analysis for circuit qualification in any VDSL2 band plan (8, 12, 17 and 30 MHz)
- Loop and fault analysis using proven TDR and FDR techniques for VDSL2 or ADSL2+ prequalification
- Measurement and reporting of suspect voltages, opens and shorts
Simplifying FTTx Testing
Thanks to its DSL and dual Ethernet ports, the MaxTester 635 is a flexible tool for service providers qualifying services, from the central office or remote terminals to the customer’s equipment. The MaxTester 635 also provides powerful troubleshooting applications that can be used in different modes to quickly isolate faults no matter where they are located (network, outside plant, customer equipment or inside wiring).
Even in hybrid networks where FTTH is also deployed, the Ethernet ports of the MaxTester 635 can be used inside the home to test at any point where a LAN connection is available.
Comprehensive Metallic Testing
Verification of copper quality is a snap with the copper measurement capabilities of the MaxTester 635. Sporting industry standard AC and DC voltage measurements, resistance (shorts) and capacitance (opens) measurements, power influence and impulse noise, technicians obtain results that are graphically clear and concise with pass/fail indications.
The MaxTester 635 also features a POTS dialer and an optional TDR and resistive fault locator (RFL) for pinpointing loop faults. The optional wideband testing suite allows the qualification of circuits at VDSL2 frequencies of up to 30 MHz and includes PSD, impulse noise and attenuation analysis.
To boost their revenues, many service providers are using DSL to deliver new multiplay services on their existing networks. Among these services, video (IPTV) is one of the fastest growing and is getting a high level of focus and investment. Knowing that customers are very sensitive when it comes to IPTV QoS (i.e., picture quality due to packet loss, zap time, etc.), technicians must be equipped with the right test sets to quickly and efficiently turn up IPTV services and meet customers’ QoS expectations.
With this in mind, the MaxTester 635 offers an optional IPTV test suite to provide both expert and entry-level technicians with a simple method to check the operation and quality of the offered video channels.
Many telcos require that technicians use a Web browser to confirm service operation or as visual proof to show the customer. Up to now, technicians required a PC in addition to the test set to do this. Thanks to the integrated browser of the MaxTester 635, carrying a laptop to the job location is no longer necessary.
The MaxTester 635 is equipped with a browser that allows the user to access websites and load a Web page as part of any automated test, directly from the test set. Just as any other browser, it can bookmark commonly used URLs and allows the user to save new ones in real time as needed. Complete navigation and the selection of hyperlinks are all a part of this optional feature.
The MaxTester 635 provides SIP-based, voice-over-IP (VoIP) performance validation for service turn-up and troubleshooting. The VoIP function allows users to send or receive live VoIP calls to an FTB EXpert VoIP-enabled platform or IP phone. The MaxTester 635 supports industry-recognized quality metrics (e.g., mean opinion score (MOS), R-factor) and performance metrics (e.g., latency, jitter).
All the Right Features for Installation Technicians
With its small form factor, the MaxTester 635 can go anywhere the technician needs to go. It is rugged and light, and all connectors are protected from the rain—just what is needed for the demanding outside-plant environment.
Automated Service Testing
Thresholds can be set and saved for key copper and DSL parameters as well as for the data and IPTV service tests. When tests are run, users are given a clear graphical pass/fail result so they can quickly move on to the next job or investigate further. Test profiles can easily be transferred between units to ensure that all technicians from the same organization are testing to the same thresholds.
The next-generation user interface of the MaxTester 635 was designed with first-level technicians in mind. The large display features colored icons and graphics for easy configuration and operation, and is simple to use for both experienced and novice users.
Results Capture and Connectivity
In today’s highly competitive environment, QoS is paramount for service providers. The MaxTester 635 allows reports of all tests to be uploaded in a variety of formats. Therefore, service providers can keep all the results on file for future reference and confirm that all the required tests have been completed by the technician.
The MaxTester 635 is equipped with a battery using the latest technology in rechargeable cells. It provides the maximum testing time between charges, even when meeting the high-power demands of VDSL2. When charging is required, technicians can either use the optional 12 Volt vehicle charger or the supplied AC adapter.
MaxTester 635 Operational Modes
ADSL2+/VDSL2 Terminate Mode
The MaxTester 635 synchronizes with the DSLAM on the circuit in the outside plant or at the NID, allowing
authentication and service testing. Technicians can test ADSL2+ and VDSL2 single pair, ADSL2+ and VDSL2 bonding, as well as ADSL2+ PTM modes.
xDSL Pass Through Mode
The MaxTester 635 replaces the customer modem or router, synchronizes with the DSLAM, and enables authentication and service testing. It also allows the customer’s applications to be used to confirm the correct operation for services such as PC Web access, IPTV viewing, STB operation and VoIP.
Ethernet Terminate Mode
The MaxTester 635 automatically synchronizes with 10/100Base-T ports inside the customer premises and allows authentication as well as service testing. In this configuration, the MaxTester 635 can be used in xDSL (FTTN), xPON (FTTH) or Ethernet deployments.
Ethernet Pass Through Mode
The MaxTester 635 automatically synchronizes with 10/100Base-T ports inside the customer premises as traffic is passed between both Ethernet ports. In this configuration, the MaxTester 635 can be used in xDSL (FTTN), xPON (FTTH) or Ethernet deployments.
