REDEFINING RATE AND REACH P h y l o g y TM Delivering proven solutions that extend bandwidth in ADSL1 andADSL2+accessnetworkssince ,Phylogy'sbest-of- breed xDSL line conditioning technology is currently installed in over 120 wireline carriers across the US,South America,andEurope. 2002 DOUBLES AREA IPTV SERVICE VSL2 DSLAM 25 Mbps STANDARD VDSL2 STANDARD VDSL2 25 Mbps EXTENDED VDSL2 EXTENDED VDSL2 3Kft 6Kft Break Through the 3Kft Barrier to 25 VDSL2Mbps Break Through the 3Kft Barrier to 25 VDSL2Mbps Break Through the 3Kft Barrier to 25 VDSL2Mbps ì ì î î Doubles the IPTV Service Area of existing DSLAMS Can Double Revenue from existing IPTV DSLAMs Cuts the Cost of Deploying New VDSL2 30 - 70% Leverages ROI on all existing VDSL2 assets Reduces the Time to Deploy VDSL2 up to 90% ì Fundamentally Scales ROI across IPTV Access Networks
  2. 2. The TLC Advantage Scaling the Network Design Rules for VDSL2 By reliably extending VDSL2’s 20mbps service reach up to 85% and 25mbps by 65%, carriers can now plan IPTV service areas up to 100% larger than currently possible using a single DSLAM site. This augmented reach means the capital resources supporting each IPTV DSLAM (like backhauls, remote terminals, and switchports)canbeamortizedovertwiceasmanyhomespassed: q q q Doubling the IPTV revenues per DSLAM shelf Increasing bandwidth utilization of backhauls Improving the utilization efficiency of all VDSL2 assets across the entire access network. TLCs Leverage the Key VDSL2 Metrics The use of TLCs improves all the key metrics in IPTV access architecture, letting carriers strategically scale their VDSL2 network design rules. This fundamental advance in network design reduces network complexity and cost, accelerates profitability,andstrengthenslong-termROI. 3 4 5 6Kft 2.8 Kft GAIN for 20 Mbps 9 Mb GAIN Data measured on 26AWG binder group (25 pr BKTA) running 8 lines of VDSL2 at Phylogy Interoperability Testing Lab TLC Conditioned Unconditioned VDSL2 9.7Mb GAIN Mbps 26 22 18 14 Nominal TLC Gain in VDSL2 Performance TLCBandwidthPerformancewithinaBinderGroup The rapid drop-off in VDSL2 bandwidth over distance is commonly attributed to the degradation of the high-frequency portion of the DSL carrier signal due to copper impedance. But anemergingissueisthecrosstalkwithinthecopperbindergroup whichalsocriticallylimitsVDSL2reach. Phylogy has focused extensively on solving this challenge, testing multi-pair performance in our network interoperability lab. The table below shows the bandwidth for eight simul- taneous lines of VDSL2 running in a 25-pair, binder group. The top table shows unconditioned VDSL2 and the bottomlistsTLC-conditionedperformancepast2Kft. 26AWG Breaking Through VDSL2’s 3Kft Barrier The Technology The Science Behind TLC’s Patented Technology q q q q q When a TLC is inserted into the VDSL2 circuit half way between the DSLAM and the CPE modem, the VDSL2 chipset re-initializes and then senses the TLC as the modem. Since the TLC is 50% closer than the CPE, the VDSL2 chipset characterizes this as a cleaner circuit, reducing its power gain and loading more bits into the higher PSD masks. This “PSD shaping” induced by the TLC results in DSL carrier noise being up to 6dB lower when it arrives at the TLC node. TLCs then apply additional active noise cancellation using common-node rejection to notch-filter RF interference. Next, full-spectrum amplification using variable DC gain is applied. During initialization, TLCs profile the carrier amplitude received form the DSLAM and apply DC gain to compensate for line loss, . Selective spectrum amplification then further boosts higher frequency PSD bins. Using peaking equalization, the TLC boosts gain on those data-rich PSD bins in the higher spectral range of the copper medium. optimized on a line-by line basis TLCs are deployed as 2.5 x 4” dual-port line cards housed in weatherized enclosures. They are spiced into existing or new VDSL2 lines midway be- tween the DSLAMandtheCPEmodem,andpoweredbythePOTS48V. TLCs operate only on the VDSL2 carrier envel- ope. No decoding, IP, or repeater functions are performed, and TLCs are compatible with all VDSL2 bandplans. Fully xDSL standards- compliant, TLCs can be deployed in mixed ADSL1, ADSL2+, and VDSL2 environments, and Phylogy is the only manufacturer of VDSL2- compliantlineconditioners. TripleStream Line Conditioning: Phylogy’s “TLC ” TM TM IPTV DSLAM 10-LINE TLC CPE / MODEMS The VDSL2 Challenge Original VDSL2 performance specifications and resulting DSLAM design rules were intended to serve 25Mbps out to 4.5Kft. Yet today many VDSL2 modems will not even sync over 3.5Kft. VDSL2's inability to meet original design rules means that IPTV networks cost significantly more than anticipated. Now Phylogy’s proven ability to extend 25Mbps IPTV service out to 5Kft brings IPTV networking costs back into line to improve bottom-line performance for wireline carriers.

  3. 3. TLCs Offer “Best Practices Engineering” to Optimize ROI for IPTV Access Loops To fundamentally improve ROI and profitability of IPTV services, TLCs deliver a network-wide scaling factor that can broadly impact core business aspects of the access loop architecture. Thus, we offer our approach as a “Best Practices Network Engineering” option which significantly improves both network performance and the utilization efficiency - and ROI - of all existing xDSL assets including DSLAMs, remote terminals, fiber backhauls,andCOswitchports. q q q q Aggregate more IPTV subscribers per DSLAM Require fewer switchports per service area Require fewer remote terminals per service area Concentrate higher bandwidth per backhaul, and reduce the need for additional fiber Reducing VDSL2 Networking CAPEX Installing a new IPTV Remote Terminal (RT) entails hidden costs beyond just the obvious equipment and labor. Up to 30% of the cost of a new IPTV overlay can be spent in re-arrangement of copperlegsneededtoreachthenewRTsite. Real-world comparisons of these costs show that installing high density TLC cabinets instead of new IPTV RT/DSLAMs can cut CAPEX costs by one-third. For low-density applications using pole or pedestal mounted TLCs , IPTV carriers can cut access networkCAPEXupto70%. TAKE THE PHYLOGY “PMO” CHALLENGE: DEPLOY TLCs OR NEW RT / DSLAMs?
