ITU
APPROVES OPTICAL TRANSPORT NETWORK (OTN) STANDARDS
The International
Telecommunication Union (ITU) approved ITU-T Recommendation G.709,
which specifies the interfaces for interconnection between service
providers/network operators that are using equipment from
different vendors. The
ITU also approved ITU-T Recommendation G.959.1, which specifies
physical layer interfaces for the OTN.
The ITU is also working on standards for automatic switched
transport networks and their control mechanisms.

ITU
APPROVES DSL STANDARDS
The International
Telecommunication Union
(ITU) approved a global standard for Single pair High
bit-rate Digital Subscriber Line (SHDSL) transceivers.
SHDSL is a multi-rate DSL technology that allows data rates
from 192 kbps to 2.312 Mbps and can transport T1 (1.544 Mbps), E1
(2.048 Mbps), ISDN, ATM and IP signals. The framing to support
these various types of signals is negotiated at start-up using the
‘handshaking’ protocol defined in ITU-T Recommendation
G.994.1. The ITU also
approved several other standards and recommendations for ADSL,
including:
- Method
for DSL systems to negotiate mutually supported operating
modes (G.994.1)
- Reference
architecture for ADSL systems (G.995.1)
- Test
methods for ADSL systems (G.996.1)
- Management
of ADSL systems (G.997.1)
- Home
Phone-line Networking transceivers, (G.989.1.)

ACCORDION
ANNOUNCES MULTI-SERVICE ACTIVATION PLATFORM FOR NETWORK EDGE
Accordion Networks, a
start-up based in Fremont, California, has announced its OnsitePOP
multi-service activation platform that integrates the
functionality of Layer 3+ switches, edge routers, QoS Engines, and
IP service switches. The
platform is designed for fine-grained service activation and
management of legacy and emerging applications at the network
edge. The OnsitePOP
platform, which includes two gateways and a service management
system, can simultaneously and natively switch IP, ATM and TDM
traffic. A Gigabit
Ethernet module will be available in Q4 2001.
A beta version of the platform will enter trials this month
with Advanced Telcom Group. The
first commercial release of the platform will take place in Q2.

- The
Onsite Service Gateway (OSG) 6000 is a carrier class Layer 2-7
switch with a 30 Gbps non-blocking switching fabric that is
scalable to 60 Mbps. It
integrates the functionality of Layer 3+ switches, edge
routers, QoS Engines, and IP service switches and offers 72
redundant subscriber ports for 26 Mbps symmetrical capacity
per subscriber over copper, and fine grain end to end QoS for
voice/data/IP services. The
OSG 6000 is designed for business campus, building, or Metro
POP installations and can be expanded with hot swappable line
cards. The OSG
100 is a tenant voice/data access device that can be
configured for 16 POTS lines with high-speed data or 8 POTS
lines and one T1 voice line with high-speed data.
- Since
its founded in August, 1999, Accordion Networks has raised $20
million in venture capital from Crescendo Ventures, Accel
Partners, Texas Pacific Group and Intel.
BANDWIDTH9
TO DEVELOP TUNABLE OPTICAL FILTERS FOR DWDM METRO NETWORKS
Bandwidth9, a
manufacturer of optical subsystems, will develop
variable-wavelength, tunable optical filter subsystems for use in
DWDM metro networks. The
filters will make possible fully tunable Optical Add-Drop
Multiplexer subsystems capable of OC-48 rates and beyond, enabling
remote provisioning and dynamic assignment of protocol-transparent
wavelengths in metro area optical networks.
Bandwidth9’s filters will utilize the company’s
Vertical Cavity Surface Emitting Laser (VCSEL) and
Micro-Electrical-Mechanical Structure (MEMS) tuning technology and
will operate in the C-Band and L-Band frequency ranges.
The company will incorporate the filters in its MetroFlex
optical transmission product line by the end of 2001.

- In
testing of its MEMS tuning technology in a filter
configuration, Bandwidth9 says that it has been able to
variably control the reflection of unselected wavelengths,
while simultaneously allowing a selected wavelength to pass
through the device and be received.
- Bandwidth9
was founded in 1997 by Connie Chang-Hasnain, Ph.D., who was
previously a professor at UC Berkeley and Stanford, and was a
Member of Technical Staff at Bellcore/Telcordia.
Other members of the company’s technical staff have
experience from APT/Coherent, AT&T Bell Labs,
Scientific-Atlanta and SDL.
- Bandwidth9
is headquartered in Fremont, California and has raised has

OPTICAL
SOLUTIONS SELECTED FOR FTTH IN SOUTH CAROLINA
Optical Solutions will supply its passive optical FiberPath
product set for a fiber-to-the-home (FTTH) deployment in the
Daniel Island community in Charleston, South Carolina.
The fiber connection will deliver telephone service, 60
channels of analog cable television and 8 Mbps Internet access to
each subscriber. The
developer anticipates offering 100Mbps data capacity, unlimited
analog and digital video selections and pay-per-view services over
time. http://www.opticalsolutions.com
Optical Solutions, February 9, 2001
- Optical
Solutions’, FiberPath encompasses three sets of
equipment: a head-end bay of equipment, which can be
co-located with a class 5 switch or interconnected through a
GR-303 interface, a PON and a customer premise node. The
head-end bay sends and receives laser-driven light signals to
and from a residence-mounted node via the passive optical
network. The node is Optical Solutions' Home Universal
Demarcation Point (HUDP), which converts the optical signals
into electronic signals needed for subscribers' existing
telephones, televisions and data modems.
GE,
MICROSOFT TO FORM NEW COMPANY TARGETING HOME NETWORKING
General Electric, Microsoft and SMART LLC formed a new venture
to offer simplified, Internet “connected home'' solutions for

TIME
WARNER CABLE DEPLOYS AP ENGINE’S SERVICE CREATION AND USAGE
MEDIATION SOFTWARE
Time Warner Cable
will deploy AP Engines' AP InterLink Open Access platform as a
means of achieving its commitment to carry multiple ISPs over its
broadband cable systems. AP Engines’ service creation software

BELL
LABS TESTS QUANTUM MECHANICAL EFFECTS IN MEMS DEVELOPMENTS
Researchers at Lucent Technologies’ Bell Labs have developed
a microelectromechanical systems (MEMS) see-saw that moves in
response to a little-known but strong and pervasive force
predicted by quantum mechanics.
The experiment, which is reported in a forthcoming issue of
the journal Science, shows that quantum mechanical effects play a
significant role in MEMS systems when the separation between
components is in the nanometer range.
