LSA-TL

HOW DEXGREEN AND THE LSA-TL SOLUTION HELPED BT OPENREACH REDUCE FAULTS AND IMPROVE PERFORMANCE…



PROJECT OVERVIEW

Providing service to more than 22 million customers across the United Kingdom, BT Openreach engineers spend a lot of time in copper cabinets. Like most carriers around the world, BT needs more speed, greater reliability and fewer faults from its existing copper network. In 2014 the company began researching ways to not only source reliable, economical components and connectors but also improve their cabinet technology and thereby advance the service it could provide.

SWEAT THE NETWORK

It was an opportunity to address the pressing issue of increasing faults throughout the network and changing needs of the infrastructure due to new service offerings, as well as to improve how the cabinets were used and managed by the engineers themselves. The team sought to save money by reducing task time for engineers and cutting the cost of materials. They also needed to find more water-resistant outside plant solutions to address the increased flooding and condensation caused by climate change.

BT invited several of the world’s leading telecom network component providers to examine options with their senior engineering team. The proposed solutions were assessed through a detailed 16-point adjudication process, and in the end, the BT Openreach team found that Dexgreen’s innovative, competively priced solution, their ability to collaborate and their capability to quickly deliver a quality product were what they needed.


A RADICAL CHANGE

As chosen supplier, Dexgreen and its partner Cobinet worked closely with Openreach engineers, service delivery managers and fault volume reduction experts to refine a customised solution based on its innovative new LSA-TL disconnection module. Uniquely designed to solve the progressing issues of water ingress and changing climates, incorrect tool usage, increased intervention and component degradation, the LSA-TL module presented an answer to all of BT Openreach’s concerns. BT Openreach Chief Engineering team hailed the reworked cabinet system as “a welcomed radical change to our copper cabinet technology.”

The new system is more logical and easier for operators to work on.


INNOVATION IN COPPER

The TL stands for ‘tool-less’, and it’s one of the new module’s most distinctive features. Technicians can operate connection sliders with their fingers, and jumpers stay terminated when sliders are withdrawn, preventing accidental faults. To counteract moisture ingress and condensation, terminations are encapsulated in a flexible silicone gel that stays intact for hundreds of terminations, depending on exact use, and is even fully submersible to allow for quicker recovery from flooding.

IDC terminals are at 45º to the wire, offering greater surface area for the connection and resulting in better conductivity and higher broadband performance. A separate ‘disconnect’ test port allows terminations to be tested both ways without removing wires and disrupting service. Plus, extra room between modules, reimagined cable management features and high-quality accessories make LSA-TL cabinets easier to work in, which minimises time, cost and, most importantly, faults.


NEXT GENERATION

In 2015 BT Openreach rolled out its ‘Next Generation PCP’ system, built around the LSA-TL module. Lawrence hailed the technological and ease-of-use benefits, stating, “The new system is more logical and easier for field people to work on and allows quality standards to be achieved more easily.”
