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:

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.

Nominal TLC Gain in VDSL2 Performance

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

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.

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. 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.

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?
Whether the goal is to incrementally add new customers to existing CO or RT-based DSLAMs, or to install an entirely new
IPTV service area, the integration of TLCs into your network design will prove to be the faster, cheaper, and smarter option
than Present Methods of Operation (PMO)
