BROADCOM
INTRODUCES CABLE HEADEND CHIPS, TRIPLING DOCSIS/EURODOCSIS
CAPACITY
Broadcom
introduced a pair of upstream and downstream advanced
PHY headend chips that will triple the bandwidth
capacity of DOCSIS/EuroDOCSIS
cable networks. Broadcom’s
Universal Advanced TDMA Dual Burst Receiver and
Universal Advanced Downstream Modulator are designed
for Cable Modem Termination Systems (CMTS), which are
located at the cable operator's headend and are used
to convert data and voice traffic to signals that can
be carried over the cable network.
The upstream, Advanced TDMA headend receiver
boosts upstream capacity by a factor of three by the
use of 64-QAM (Quadrature Amplitude Modulation)
techniques and higher symbol rates.
A more powerful error correction algorithm
delivers greater robustness to mitigate the effect of
impulse and burst noise on interactive services.
It also contains an integrated FFT (Fast
Fourier Transform) processor that allows advanced
spectrum management of the entire reverse path
spectrum (5-65 MHz) without disrupting traffic.
Broadcom’s new downstream Advanced PHY
Modulator increases line speed 2.5 times to 100 Mbps
from the current 40 Mbps for standard DOCSIS
1.0/1.1 products.
It also includes an integrated burst modulator,
which creates the out-of-band (OOB) channel that is
used to control subscriber video equipment, including
set-top converters.

BROADCOM
LAUNCHES ITS SIXTH-GENERATION CABLE MODEM CHIP
Broadcom
introduced its sixth generation chip for PCI
and external Ethernet/USB
cable modems. The
new low-cost, single-chip cable modem offers twice the
bandwidth and throughput of current DOCSIS
modems. The DOCSIS/
EuroDOCSIS 1.0 and 1.1-capable chip incorporates
support for Broadcom's unique packet-accelerating
software, which enables cable modem termination
systems (CMTS) to serve twice as many users on a given
upstream channel.
The software is driven by a 140 MHz MIPS-32 CPU
that delivers a 66% improvement in packet throughput
over prior generations.
The device also includes an integrated 10/100 Ethernet
MAC/PHY and a USB 1.1 interface that enables simple
plug-and-play installations. http://www.broadcom.com

- Separately,
Broadcom announced a reference design that enables
digital video recording (DVR) and home networking
capabilities in set-top boxes running on the
Microsoft TV platform.
MOTOROLA
SHIPS 15 MILLIONTH DIGITAL SET-TOP, 5 MILLIONTH CABLE
MODEM
Motorola Broadband Communications Sector
reached two significant industry milestones with its
15 millionth interactive digital cable set-top
terminal shipment and its five-millionth cable modem
shipment (3.8 million DOCSIS modems).
Last year, Motorola reached its 10 millionth
interactive digital set-top shipment and its one
millionth DOCSIS cable-modem shipment.

MOTOROLA
OUTLINES THE STRATEGIC DIRECTION FOR ITS SET-TOP BOXES
The
next generation of Motorola's flagship DCT5000
set-top boxes will include support for HDTV decoding
as a standard feature, PVR (Personal Video Recorder)
capabilities, an HPNA home-networking option, and an
updated front-panel I/O for USB,
Ethernet, wireless interfaces and A/V inputs.
The PVR capability is enabled with the
addition of a 20 - 60 GB internal hard disk drive.
Motorola's DCT5000 development plans include a Web
pad, which is a wireless, hand-held, touch-screen
device that gives viewers Web access via the set-top
without interrupting the TV viewing experience.
Motorola is also working to deliver additional
streaming and home-networking capabilities, dual-PVR,
and the next generation of USB (2.0).

ADC’S
OPEN ACCESS CABLE PLATFORM LEVERAGES MPLS FOR ENSURING
SLAS
ADC announced its integrated open access
solutions allowing cable operators to support multiple
ISPs for their subscribers.
ADC’s next-generation, Cuda 12000 cable modem
termination system/Edge Router provides quality of
service support, policy-based routing, subscriber
management and provisioning, and network diagnostic
tools. By
distributing policy-based routing to the edge of the
networks, ADC said cable operators would be capable of
implementing QoS on a per ISP and application basis,
both on the DOCSIS access network and metropolitan
area network. The
system offers DOCSIS
1.1 and DiffServ capabilities.
It also leverages MPLS to enable wire-speed
per-flow traffic control and allows cable operators to
control and properly monitor individual flows for
multiple services from multiple ISPs.
ADC’s CMTS also adds support for the internal
BGPv4 routing protocol, which complements existing
support of the RIP v1/2 and OSPF v2 protocols, and in
many cases eliminates the need for separate edge and
WAN/MAN platforms.

ADC, June 11, 2001
- ADC’s
Cuda 12000 IP Access Switch is a 14-slot
access & routing platform that aggregates high

transport over backbone data networks and the
Internet. The
system is based on several custom ASICs and
programmable network processors.
The DOCSIS
and EuroDOCSIS-qualified Cuda 12000 platform has
been deployed by more than 30 cable operators
worldwide.
NARAD
DEVELOPS “VIRTUAL FIBER” FOR FAST ETHERNET
SERVICES OVER HFC NETWORKS
Narad
Networks, a start-up based in Westford, Massachusetts,
unveiled a “virtual fiber” architecture for
delivering symmetrical, 100 Mbps to 1 Gbps Ethernet
services over HFC networks.
The architecture places Gigabit Ethernet
switches at strategic points in the network. An
Optical Network Distribution Switch (ONDS) located
immediately next to a conventional optical node
combines the signals below 860 MHz from the headend
with Gigabit Ethernet signals from a headend router.
The ONDS performs an optical-to-electrical
conversion of Ethernet traffic selectively at 100 Mbps
or 1 Gbps. A
Network Distribution Switch (NDS) provide the
functions of a distribution amplifier for signals
below 860 MHz as well as trunk-to-trunk switching
functions between the 1 Gbps Ethernet channels.
Narad will also provide a subscriber access
switch and a customer premise unit with Ethernet ports
and a single coaxial interface for existing TV and
cable modem services operating below 860 MHz.
