Ensuring the highest quality triple-play services to customers is a must for service providers, but it is also quite a challenge with aging copper plant. One industry standard method that helps achieve this is the xDSL impulse noise protection (INP) parameter, which is particularly important when deploying IPTV services based on VDSL2 and ADSL2+. For example, INP helps reduce the amount of macro-blocking in an IPTV stream caused by short duration and intermittent impulse noise spikes. The MaxTester DSL has a complete implementation of the ITU-T INP standard for values ranging from 0 to 16.

Simplifying FTTx Testing
Thanks to its xDSL and dual Ethernet ports, the MaxTester DSL is a very flexible tool for service providers qualifying service all the way from the central office to the customer’s equipment. The MaxTester DSL also provides powerful capabilities in troubleshooting applications where it 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 being deployed, the MaxTester DSL’s Ethernet ports can be used inside the home to test at any point where a LAN connection is available.
IPTV Testing
To boost their revenues, many telcos are using xDSL to deliver new triple-play services on their existing networks. Amongst 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, technicians must be equipped with the right test sets to quickly and efficiently turn up IPTV services and to meet customers’ QoS expectations.
With this in mind, the MaxTester DSL 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. The MaxTester DSL can act as the subscriber’s IPTV set-top box (STB) on either the xDSL circuit or the Ethernet interface at the customer premises. With the IPTV Auto Test feature, the MaxTester DSL can automatically join and leave, or simultaneously join multiple chosen channels. Zap time and key service parameters (including packet loss) can also be gathered for each channel and simple graphical pass/fail indicators show per-channel performance results, which are compared against pre-programmed thresholds.
Web Browser
Many telcos require that technicians use a Web browser to confirm service operation or as visual proof to the customer. Up to now, technicians required a PC in addition to the test set to do this. Thanks to the MaxTester DSL’s integrated browser, carrying a laptop to the job location is no longer necessary. The MaxTester DSL browser allows the user to access websites and load a web page as part of any auto 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.
Data Service Testing
Data services are the backbone of most broadband networks, and subscribers continue to have higher and higher expectations of network performance as the popularity of multimedia sites and services continues to accelerate. For this reason, technicians must not only test the connectivity of data services but they must be able to validate performance against committed service levels.
The MaxTester DSL data services test suite meets these requirements by providing automated tests for IP ping, traceroute and FTP upload/download. As with all the MaxTester DSL tests, the data services tests can be executed over the xDSL or Ethernet interfaces for thorough installation and troubleshooting in the outside plant and inside the customer premises.
The MaxTester DSL Operational Modes
ADSL2+/VDSL2 Terminate Mode
The MaxTester DSL synchronizes with the DSLAM on the circuit in the outside plant or at the NID, allowing authentication and service testing.
xDSL Pass Through Mode
The MaxTester DSL replaces the customer modem or router, synchronizes with the DSLAM, and allows authentication and service testing. It also permits 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 DSL automatically synchronizes with 10/100Base-T ports inside the customer premises and allows authentication as well as service testing. In this configuration, the MaxTester DSL can be used in xDSL (FTTN), xPON (FTTH) or Ethernet deployments.
Ethernet Pass Through Mode
The MaxTester DSL automatically synchronizes with 10/100Base-T ports inside the customer premises as traffic is passed between both Ethernet ports. In this configuration, the MaxTester DSL can be used in xDSL (FTTN), xPON (FTTH) or Ethernet deployments.
Applications
- Ensures the customer has the required bandwidth (downstream and upstream rates) for delivering triple-play services
- Assesses connectivity all the way to the customer equipment over most technologies
- Ensures the IPTV and data services can operate on the circuit with the required QoS
- Verify if the customer’s modem/router, equipment and inside wiring are working correctly
- Proves data flow between the network and end equipment
All the Right Features for Installation Technicians
With its small form factor, the MaxTester DSL can go anywhere you need 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 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 onto the next job or investigate further. Test profiles can be easily transferred between units to ensure all technicians from the same organization are testing to the same thresholds.
Easy to Use
The MaxTester DSL’s next-generation user interface has been designed with the first-level technician in mind. The large display makes use of colored icons and graphics for easy configuration and operation, simple to use for experienced and novice users alike.
Capturing Results and Connectivity
In today’s highly competitive environment, quality of service is paramount for service providers. MaxTester DSL allows reports of all tests to be uploaded in a variety of formats. Therefore, service providers can keep all results on file for future reference and confirm all required tests have been completed by the technician.
Battery Powered
MaxTester DSL is fitted with a battery using the latest technology in rechargeable cells. It provides the maximum testing time between charges, even when using 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.
