Ubiquitious DSL Deployment Now Possible With Highly Integrated Digital Loop Carriers.
February 8, 1999 -- The Digital Subscriber
Line (DSL) market just got another boost
today by way of Digital Loop Carriers
(DLCs). Centillium Technology Corporation
announced that Advanced Fibre
Communications®, Inc. (AFC) has selected
the Centillium CopperLite chipset for the
G.Lite ADSL (G.922.2) plug-in card for AFC's
flagship product, the UMC 1000
Multi-Service Access Platform. As a leading
manufacturer of networking equipment for
the "local loop'' between telephone service
users and public telephone networks, AFC's
adoption of the Centillium CopperLite
chipset is expected to enable
telecommunications carriers to deploy
low-cost, high-performance DSL services to
worldwide markets more rapidly and
cost-effectively than ever before.
DLCs are quickly becoming the prevalent
technology for delivering voice and data
services over "last mile copper networks'' in
every part of the world. In the United States,
greater than 20% of local telephone lines
terminate in a DLC, including up to 70% of
all new line growth. Until now, however,
carriers have been unable to cost-effectively
deploy DSL line cards in remote cabinet
DLCs due to severe power, rack space, and
temperature constraints.
The UMC 1000 from AFC overcomes these
challenges with G.Lite DSL plug-in cards
based on the CopperLite chipset. The
Centillium chipset supports the industry's
highest port density -- up to eight DSL ports
per chipset -- enabling AFC to provide more
DSL lines using less rack space in a small
DLC. The CopperLite chipset also eliminates
costly infrastructure upgrades by offering
the industry's lowest power consumption
(0.65 watts/per port) and ensures software
upgradability over time by delivering ample
processing power.
"Both large and small telephone companies
worldwide tell us that speed and profitability
are critical to their success in deploying DSL
services,'' said Philip Yim, Director, Product
Planning, AFC. "To achieve rapid
deployment of DSL in the local loop, carriers
must be able to upgrade their existing
infrastructure instead of building an entirely
new one. AFC is committed to providing
solutions compliant with the emerging G.Lite
standards, which will accelerate and ease
deployments of ADSL services. This new
solution from Centillium and AFC allows
carriers to leverage their installed base of
existing equipment simply by adding new
G.Lite DSL plug-in cards to their DLCs.''
"The power, temperature, and rack space
requirements are far more limiting for a DLC
in a remote cabinet than for a DSL Access
Multiplexer in a central office,'' said Al
Gharakhanian, Director of Marketing for
Central Office Products, Centillium
Technology. "The highly integrated
CopperLite chipset, combined with the
innovative and flexible architecture of AFC's
UMC1000 platform, has removed one of the
last barriers to mass deployment of DSL
technology in both DLCs and central
offices.''
Centillium CopperLite Delivers DSL in
Digital Loop Carriers
The two-part CopperLite CO (central office)
chipset consists of the CT-L10DC08 Digital
chip and CT-L10AC08 Analog chip.
Networking equipment manufacturers can
use these cost-effective, power-efficient
chip sets as the foundation for multi-port
line cards in both carrier-class DLCs and
DSL Access Multiplexers (DSLAMs). In
addition to AFC, several other major
manufacturers of telecommunications
equipment have standardized on Centillium's
CopperLite CO chipset.
The CopperLite CO chipset is highly
integrated and offers maximum port density,
supporting up to eight DSL ports with just
two chips. Very low power requirements
help keep power dissipation to just 0.65
watts per port. The CopperLite CO chipset is
based on Centillium's software-upgradable
Communications DSP, which ensures long
product life cycles without the need for
costly hardware upgrades. The chipset
provides end users with high-bandwidth
Internet access at speeds of 1536kbps
downstream and 512kbps upstream over
"Plain Old Telephone Service'' (POTS)
regular copper phone lines. That is up to 27
times faster than conventional 56kbps
analog modems. |
