DSL.Lite on trial in Oregon

By Tim Greene
Network World, 10/29/98

Portland, Ore.- GTE has leapt into a trial of easy to
install digital subscriber line (DSL) technology.

Following the announcement last week that an
international standard for the easy-install DSL, known
as DSL.Lite has been formalized, GTE said they have
been conducting a trial of the technology in Portland,
Ore., for the past 30 days.

The goal of the trial is to find out how well DSL.Lite
works in the real world over existing phone lines and
using existing phone wiring inside homes.

DSL.Lite is a slower version of asymmetric DSL
(ADSL). Whereas ADSL can reach download speeds
of 7M bit/sec, DSL.Lite's maximum download speed
is 1.5M bit/sec.

In exchange for the lower bandwidth, DSL.Lite can
perform on a regular phone line without the need to
install a filter, known as a splitter, this protects the
voice channel on the line from noise produced by the
DSL data stream.

Installing a splitter is a complication and an expense
that many service providers would like to avoid.

So far, GTE has 20 DSL.Lite lines installed in homes
ranging in age from new to 50 years old. Trial
customers, all employees of Intel, get a DSL.Lite
modem from Orckit that connects to their PC via an
Ethernet port. Customers can then use the line to
access the Internet and to make regular voice phone
calls simultaneously.

One problem identified so far is that the quality of
voice connections can be poor on a DSL.Lite line,
depending on how good the actual phones are.

So GTE has provisioned the DSL.Lite modems to
drop their speed so they will run quieter when anyone
picks up a phone in the house.

The best case so far has the speed of the DSL.Lite
download connection dropping from 1.5M bit/sec to
480K bit/sec when a phone extension is picked up in
the home.

Depending on the quality of the telephones in the
home, the DSL.Lite connection can still be disrupted
when a phone call is made. In those cases, GTE is
installing a filter that sits between the phone and the
wall jack.

So far, GTE technicians have installed the DSL gear
so they can gather information about the line quality
and the quality of phone wiring inside the home.

During the second phase of the trial, scheduled to start
next month, customers will be given a modem and
instructions on how to install it. "We will call the next
day to see how well they did," said Bev White,
program manager for new business development at
GTE.

The trial will eventually be extended to 50 customers.
