You need VDSL2 and Ethernet to deliver HD IPTV
VDSL2’s high-speed capability not only breathes new life into your existing copper plant but it allows you to reduce churn and gain market share in delivering triple-play services to your customers. High-definition (HD) IPTV service is the killer application for VDSL2 deployment as it requires the most bandwidth and the best quality of service (QoS) that your customers have come to expect.
EXFO’s AXS-200/630 offers a quick, yet thorough method for testing triple-play services—VDSL2 and Ethernet-based data, VoIP and IPTV testing—using pass/fail-driven automated functionalities.
In addition to validating connectivity to the DSLAM, the AXS-200/630 provides upstream and downstream parameters such as actual data rates, attenuation and noise margin. What’s more, it delivers advanced IPTV measurements—packet jitter, packet loss, PCR jitter, MDI, PID viewer and IGMP zap time—both in Terminate (stand-alone) and Through mode operation. The AXS-200/630 also monitors residential VoIP call flow and statistics, facilitating VoIP QoS assurance.
Impulse noise protection +
You need to provide your customers with comprehensive assurance against poor triple-play services. With this in mind, the telecom industry has adopted the DSL-based impulse noise protection (INP) parameter, which is particularly important when deploying IPTV services based on VDSL2 and ADSL2+. For example, the INP helps reduce the amount of macro-blocking in an IPTV stream caused by short duration and intermittent impulse noise spikes. However, the downside of standard INP implementation is that it can limit the speed of VDSL2 (or ADSL2+) offered to customers as well as the addressable service area (distance).
The AXS-200/630 supports the traditional INP parameter as well as Broadcom’s innovative approach to INP called PhyR™. This technology allows for significantly lower BER, higher DSL rate and longer reach compared to standard INP implementations. As a result, the AXS-200/630 can be used to verify and ensure consistent QoS for DSL-based IPTV deployments without impacting speed or performance of the DSL link.
True backward-compatible and interoperable testing
Since the AXS-200/630 is based on the industry-leading Broadcom chipset, you are assured of excellent interoperability for VDSL2 and ADSL2+ when testing against other Broadcom chipset-based devices as well as other manufacturer chipsets.
Thanks to the AXS-200/630’s Broadcom chipset, you can use the Broadcom’s Nitro mode when testing ADSL2+ to effectively negotiate with DSLAM (also using a Broadcom chipset) in order to achieve data rates as high as 30 Mbit/s (depending on DSLAM setup, loop length, noise influences and circuit quality).
* The MDI feature of the IPTV software option is not available in the USA.
