TLC nodes are inserted onto a DSL copper service pair between the DSLAM and the subscriber modem as shown at right. Whether using large, high-density TLC enclosures or small line count units, TLC conditioning can be planned and engineered to maximize performance on all lines served using Phylogy's network planning guidelines.

This guideline applies to DSLAMs housed at the CO or in Remote Terminals (RTs). Line insertion is performed using standard field splicing procedures which are fully documented in the installation guides at left. Phylogy supplies a fully systemized deployment solution which integrates our product design, enclosures, and field procedures to make the deployment of network conditioning a seamless, trouble-free process.

Passive-Node Technology Mean no Provisioning, EMS, or Power Supply Headaches
Operating at the physical layer only, TLCs require no circuit provisioning or EMS management integration.
Consuming only a 1/4 watt, they operate off of the existing -48V POTS line power thus requiring no installation of power supply, cooling, batteries, or rectifyers. Installation within 4 hours for small line counts is standard practice.

Flexible Enclosure Options Support Any Service Density
Whether you want to bring serivce to a single remote farmhouse or a high-density upscale neighborhood, Phylogy can deliver the cost-effective options you need -- tailored to the service densities in your areas -- based on our highly granular and flexible installation plans.

Line Conditioning Only Uses Standard Outside Plant Practices
Regardless of TLC enclosure size, all TLC chassis are simply spliced into the telco cable, using an industry-standard splice module. This single snap-fit connection, such as 3M’s™ “MS²™” splice block, is all that is required for connecting all necessary signal and power terminations needed to bring TLCs online.

Dual Powering Options
Most TLC deployments rely on the self-powering option which operate off of the existing -48V POTS line power. However where POTS powering is questionable due to line length or other issues, Express Power using a seperate copper pair powered from the CO or a crossbox is also supported.

Turning Up TLC Line Cards
Once a TLC enclosure has been spliced into the network, all power and signal terminations are active at the enclosure's backplane. Hot-plugging each TLC card into an enclosure slot is the next step:

• Using only a quarter watt at 48V, junction arcing is not a concern.
• Once installed, the card autocalibrates to adapt its circuit to match the specific line conditions for that service pair.
• Both POTS and DSL service is immediately restored.
• The xDSL line card in the subscriber's DSLAM will now re-initialize to synchronize the subscriber's modem.

Two Options for Conditioning the Access Loop
Two primarily different deployment options can be used to enable a flexible, widespread, and complementary approach to service extension

Best-Practices Network Engineering Lays Foundation to Meet Growing Demand
TLCs can be adopted as standard-practice network conditioning to engineer the DSL network to support higher aggregate bandwidth capacity and higher efficiency of all xDSL assets. Described as “Best Practices Network Engineering”, this method significantly improves both network performance and utilization of all existing xDSL assets including DSLAMs, remote terminals, fiber backhauls, and CO switchports
