They are spiced into existing or new VDSL2 lines midway be- tween the 14 DSLAM and the CPE modem, and powered by the POTS 48V.

Fully xDSL standards- TLC Bandwidth Performance within a Binder Group compliant, TLCs can be deployed in mixed The rapid drop-off in VDSL2 bandwidth over distance is ADSL1, ADSL2+, and VDSL2 environments, commonly attributed to the degradation of the high-frequency and Phylogy is the only manufacturer of VDSL2- portion of the DSL carrier signal due to copper impedance. But compliant line conditioners. an emerging issue is the crosstalk within the copper binder group which also critically limits VDSL2 reach. The Science Behind TLC’s Patented Technology Phylogy has focused extensively on solving this challenge, q When a TLC is inserted into the VDSL2 circuit half way between the DSLAM testing multi-pair performance in our network interoperability and the CPE modem, the VDSL2 chipset re-initializes and then senses the lab. The table below shows the bandwidth for eight simul- TLC as the modem. Since the TLC is 50% closer than the CPE, the VDSL2 taneous lines of VDSL2 running in a 25-pair, 26AWG binder chipset characterizes this as a cleaner circuit, reducing its power gain and group. The top table shows unconditioned VDSL2 and the loading more bits into the higher PSD masks. bottom lists TLC-conditioned performance past 2Kft. q This “PSD shaping” induced by the TLC results in DSL carrier noise being up to 6dB lower when it arrives at the TLC node. q TLCs then apply additional active noise cancellation using common-node rejection to notch-filter RF interference. q 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, optimized on a line-by line basis. q 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.
