THE OPTICAL INTERNETWORKING FORUM REPORTS PROGRESS ON
OPTICAL UNI INTEROPERABILITY
Twenty-five vendor companies participated in the
initial interoperability testing of the optical User Network
Interface (UNI) protocol that was held earlier this month at
the University of New Hampshire's InterOperability
Laboratory. The protocol enables client devices to
dynamically set-up and tear-down optical circuit connections
across the transport network. Both the control plane and
optical transport layer were verified for appropriate
behavior during the trials. All of the vendors were able to
demonstrate Optical UNI interoperability. The companies
will demonstrate their UNI signaling interoperability at
SUPERCOMM 2001 in Atlanta on June 5-7 in OIF's booth number
150D in the Georgia Dome.

LUXN DEBUTS OPTICAL SERVICE LEVEL MANAGEMENT SYSTEM,
FOUR-CHANNEL WDM CHASSIS
LuxN introduced an Optical Service Level Management
System (OSLM) capable of real -time, in-service-Bit Error
Rate (BER) monitoring to allow service providers to manage
individualized, protocol-independent Service Level
Agreements (SLAs) at the physical layer. A
wavelength-specific, user-settable threshold allows service
providers to offer different SLAs per customer, sub-network,
service, link, or wavelength. The tool generates advance
warnings of potential SLA violations, allowing operators
sufficient time to arrest further degradation of service.
General availability is expected in September.
http://www.luxn.com/press/pr_oslm5_21.shtml
LuxN also introduced a
modular WDM chassis measuring two rack-units (RU) of height
(3.5 inches). The device, which is targeted at either the
carrier's POP or a CPE location, supports up to four CWDM or
DWDM wavelengths.
Service interface modules allow the chassis to deliver Fast
Ethernet,
Gigabit
Ethernet, Fibre Channel,
T1/E1, or OC-n/STM-n traffic for hand-off to metropolitan
optical and storage networks.

COPPER MOUNTAIN INTRODUCES DSL PLATFORM FOR OFFLOADING IP
TRAFFIC FROM ATM DSLAMS
Copper Mountain
introduced its next generation platform designed to
transform installed bases of ATM DSLAMs into an IP-aware
broadband access system. Copper Mountain’s new VantEdge
3000 Broadband Services Concentrator off-loads IP traffic
from an ATM transport network, but supports end-to-end ATM
where needed. Whereas ATM-based
DSLAMs have traditionally relied on ATM switches for Layer 2
aggregation and on centralized subscriber management systems
for Layer 3 subscriber aggregation, Copper Mountain’s
solution aims to aggregate the IP traffic at the DSLAM and
route it directly via the SONET infrastructure to a regional
IP services platform. The design would subtend ATM DSLAMs
and aggregate service traffic from thousands of broadband
customers onto a few shared virtual circuits to the network
backbone. Aggregating IP traffic into service
classes on fewer PVCs back in the central office offloads
this traffic from the ATM and SMS pieces of the network and
reduces massive PVC provisioning. In
addition to its ATM support, the platform offers IP service
functions such as subscriber aggregation, policy-based
class-of-service, traffic shaping, switching, and
multicast. Network processors and a 100 Gbps backplane are
used to deliver over 1 million packets per second
performance. Beta testing is expected in Q4. The solution
is targeted at incumbent broadband providers with an
extensive installed base of ATM-based DSLAM platforms.

COPPER MOUNTAIN OFFERS VOICE GATEWAY FOR ITS IP-BASED DSLAMS
Copper Mountain introduced its
VicinityVoice 100 Local Trunk Gateway (LTG), a new
type of voice gateway, that would sit beside its DSL
concentrators and deliver a broadband
customers' local calls directly to PSTN destinations served
from the same wiring centers, thus avoiding the trunking
costs associated with sending these calls through more
distant Class 4 tandem switches. Copper Mountain’s
CopperEdge DSL Concentrators and VantEdge Broadband Services
Concentrators are equipped with IP service intelligence that
allows them to support softswitch solutions by sending calls
to a collocated VicinityVoice 100 LTG or to the wider voice
transport network, as appropriate. The VicinityVoice 100 LTG
converts IP voice packets to the Pulse Code Modulation (PCM)
signals that are processed by Class 5 switches. Product
availability is expected in Q4.

NORTEL NETWORKS JOINS XENPAK 10 GIGE MULTI-SOURCE GROUP
Nortel Networks has thrown its support to the new
XENPAK 10 Gigabit Ethernet multi-source agreement (MSA)
group. The XENPAK MSA supports the proposed 802.3ae IEEE 10
Gigabit Ethernet standard, and specifies a uniform form
factor, size, connector type and electrical pin-outs. It
covers all four transceiver types defined in the proposed
standard, including 850 nanometers (nm) serial, 1310 nm
serial, 1310 nm WWDM and 1550 nm serial. XENPAK
transceivers are very compact, allowing eight devices to be
mounted on typical line cards, but do not compromise on the
significant thermal and EMI management requirements of 10
Gigabit optical electronics.

NEW 1394B SPEC EXTENDS SPEED AND REACH FOR CONSUMER
ELECTRONICS
A new version of the IEEE 1394 specification, also
known commercially as FireWire (Apple) and i.Link (Sony)
will extend high-speed peripheral connectivity to 800 Mbps,
1.6 Gbps and 3.2 Gbps from its current 400 Mbps rate. The
new 1394b specification, which is expected to complete final
ballot recirculation this month, also supports audio and
video transfer over plastic optical fiber to 50 meters at
200 Mbps, to 100 meters at 400 Mbps, and over glass optical
fiber at up to 3.2 Gbps. A new, highly efficient bus
arbitration scheme, known as BOSS (Bus Owner Supervisor
Selector) implements overlapped, pipelined arbitration, so
the arbitration protocol runs in parallel with data
transmissions. Hybrid bus operation enables backward
compatibility with 1394-1995 and 1394a standards. Due to
the simplified arbitration signaling, the 1394 Trade
Association estimates that Costs of 1394b silicon and
1394b-enabled products will be lower than products using
earlier versions of the specification. Major serial bus
semiconductor suppliers including Texas Instruments, NEC,
Panasonic and Agere are at work on 1394b devices.
