JDSU SmartClass TPS ADSL2+ Bonded ADSL/VDSL Tester

 JDSU SmartClass TPS
The JDSU SmartClass TPS handheld helps field technicians rollout broadband access networks and services, delivering a pristine copper access infrastructure that can support triple-play services and meet critical quality-of-service (QoS) and quality-of-experience (QoE) requirements. This all-in-one tool can test copper, fiber, asymmetrical, and very-high-speed digital subscriber lines (ADSL2+/VDSL2), WiFi, coax and HPNA networks, Internet protocol (IP) data, voice over IP (VoIP), and IP video with straightforward Pass/Fail results and detailed analyses of physical- and application-layer-related problems.

To ensure that field technicians have successfully completed installation and repair jobs, the SmartClass TPS verifies the physical health of the access copper loop, digital subscriber line (DSL) performance, QoS/QoE of triple-play services, and home distribution networks. In addition, the CableCheck and OneCheck automated test suites improve technician efficiency by avoiding test configuration and result complexity, cutting test times by more than half. The iOS app expands this efficiency, enabling mobile integration.

Overall, with SmartClass TPS, operators and service providers locate and repair faults more quickly and confidently guarantee service quality.

ADSL2+/VDSL2
Technicians commonly run DSL synchronization tests at every dispatch, and the SmartClass TPS supports DSL tests for ADSL2+ (ADSL and ADSL2 included), VDSL2, ADSL2+. It provides a bits-per-tone graph that is key toward identifying disturbers and profile utilization. Typical ADSL2+/VDSL2 tests that todayﾒs field technicians require include:

DSL Test	What it Tests	Why it is Needed
ADSL2+/VDSL2 synchronization test	Synchronization in Auto mode or dedicated profile	Connection and provisioning problems.
Customer data rate upgrade	Maximum DSL rate	Applications such as IP video require more bandwidth.
Margin and attenuation	Signal-to-noise ratio margin (SNRM) and loop attenuation	Copper circuits are exposed to environmental changes. Adequate noise margin maintains the line. Higher attenuation results in lower SNR.
DSL errors	CRC, FEC, LOS, LOF, LOP	DSL errors will transfer to application layers such as IP video
Bits per tone (BPT)	Number of BPT	Identifies disturbers/interferers.
Hlog	Loop attenuation component of the channel transfer function (during the modem training phase)	Can detect bridged taps, degraded contacts and bad joints
Quiet line noise (QLN)	External noise floor of the DSL line	Shows frequency of potential disturbers/interferers on the DSL line

Hlog
Copper loops that perform well for ADSL2+ may fail dramatically with full VDSL2 performance. Short bridged taps (between 2 ﾖ 50 m/5ﾖ 150 ft) located in homes can degrade VDSL2 data rates significantly.

The graphical Hlog diagnostic mode on the SmartClass TPS easily detects bridged taps, including their approximate length and frequency areas of noise interference. A bridged tap causes a dip on the Hlog graph, which represents the attenuation per frequency of the line. The Hlog data is assessed during the DSL training phase.

Removing bridged tap faults lets operators provide more reliable DSL lines with higher data rates. And, itﾒs easy to recheck with Hlog to ensure that thereﾒs no more dip: meaning no more bridge tap.

DSL Test	What it Tests	Why it is Needed
Hlog	Loop attenuation component of the channel transfer function (during the modem training phase)	Can detect bridged taps, degraded contacts and bad joints

OneCheck
OneCheck is a fully automated, single-button application that tests DSL, data throughput, VoIP, and video with clear Pass/Fail results.

This application lets technicians overcome the complexity of testing all technologies simultaneously. OneCheck significantly reduces test times and lets technicians test all services with minimal training. Consistently following test methods and procedures, operators also reduce working CPE swap outs, second customer visits to solve problems, and repeats; all services are checked before closing a job. OneCheck results also provide insightful test data from the field which can help improve network design and overall QoS.

Test	What it tests	Why is it needed?
Physical link	DSL with pass/fail on connection rate, maximum rate, noise margin, and attenuation	High data rates achieved with VDSL and/or DSL bonding are more susceptible to impairments due to a higher transmission frequency range and complex protocols. Good QoS on data, VoIP, and video services requires a pristine physical link.
Network authentication	Network authentication using IPoE/IPoE6 or PPPoE, with user login status information	Certifying the network during customer service turn-up.
IP ping	Connectivity and delay time through the network with pass/fail results for receiving a successful ping reply within set timing thresholds (average or maximum ping time)	Network delay is crucial, especially with high-interaction applications such as gaming.
File upload	File upload rates using FTP or HTTP protocol with pass/fail results for targeted rates	DSL profile parameters, such as impulse noise protection (INP) and delay and network aggregation issues, determine user-experienced data speeds.
File download	File download rate using FTP or HTTP protocol with pass/fail results for targeted rates	DSL profile parameters, such as INP and delay and network aggregation issues, determine user-experienced data speeds.
Video	Verifies that all video channels based on a loaded channel list are available and perform according to QoS thresholds (latency, jitter, loss) with pass/fail results	Verify video channel availability and quality to meet customer expectations
VoIP	Registration at the gateway by placing an automated or manual call with call quality according to QoS thresholds (loss, jitter, delay) with pass/fail results and includes an MOS result.	Ensure that service setup and provisioning match the customer profile. Verify connectivity beyond the signaling gateway and ensure user-perceived premium call quality.
