OCTAL T1/E1/J1 framer and LIU increases integration, improves
reliability and lowers system costs PMC-Sierra, Inc. (Nasdaq:PMCS)
today announced the eight-channel PM4358 COMET(TM) OCTAL T1/E1/J1
framer with integrated analog Line Interface Unit (LIU). To address
increasing bandwidth requirements at the network edge, service
providers must provide higher density T1/E1 line cards for new and
existing equipment, while minimizing capital expenditure. The COMET
OCTAL provides the industry's most integrated solution, enabling
system designers to: -- reduce system costs, saving more than 20
percent compared to competitive solutions; -- reduce board space
with a compact package and integrated terminations, requiring 75
percent fewer line side components than competitive solutions; --
enhance system reliability with 1:1 redundancy support; and --
leverage existing firmware that is compatible with the popular
COMET and COMET QUAD devices. The COMET OCTAL provides a common
Framer and LIU solution platform for all major worldwide formats.
In a compact 17mm by 17mm package, the device provides complete
line side integration, software-selectable redundancy for 1:1
protection, software-selectable framing for three global primary
rate framing formats (T1/E1/J1) and support for short-haul and
long-haul analog line interfaces. "PMC-Sierra is committed to
providing the industry's most integrated, lowest total cost
T1/E1/J1 solutions," said Dino Bekis, vice president of marketing
for PMC-Sierra's Communications Products Division. "The COMET OCTAL
integrates PMC-Sierra's proven T1/E1 technology, while addressing
critical constraints on cost, space and power. System designers can
leverage this compact, field-proven solution to deliver the
high-density, low-cost line cards that wireless and wireline
service providers demand." Increased Integration and Reduced System
Cost The COMET OCTAL's fully integrated line side termination
reduces the number of external line side components by 75 percent
compared to available solutions. Its compact package and fully
integrated termination make it the industry's smallest total
footprint eight port T1/E1/J1 framer and LIU solution offering a
system cost savings of more than 20 per cent compared to available
alternatives. Redundancy Support for Improved System Reliability
The COMET OCTAL enhances system reliability by enabling customers
to implement software selectable 1:1 protection for redundant
applications with no additional board components. In a redundant
application, a standby T1/E1/J1 interface is used to protect an
active link, allowing a quick recovery in case of line failures.
The device also autonomously generates periodic performance
reports, which reduce the software overhead associated with meeting
T1 Standards in high-density designs. A Family of Highly Integrated
T1/E1/J1 Solutions PMC-Sierra today also introduced the
four-channel PM4359 COMET TETRA T1/E1/J1 framer with integrated
analog LIU. Both devices are hardware and software compatible,
allowing designers to develop a single design for both four- and
eight-port applications. The COMET OCTAL and COMET TETRA
architectures are based on PMC-Sierra's PM4354 COMET QUAD, the
industry's first 3.3V integrated four-channel T1/E1/J1 framer/LIU
device. As a result, designers are able to leverage software
developed for the COMET QUAD for new eight port designs with the
COMET OCTAL. The COMET OCTAL and COMET TETRA are compatible with
PMC-Sierra's Layer 2 solutions, such as FREEDM (HDLC Controller for
PPP, Multi-Link PPP, Frame Relay and Multi-Link Frame Relay), IMA
(Inverse Multiplexing for ATM) or AAL1gator (AAL1 Circuit
Emulation), which provide proven interoperability (See Figures 1
and 2). Alternatively, the COMET OCTAL and COMET TETRA provide a
key portion of a total solution based on commercially-available
network processors, such as Wintegra's Winpath product family,
through a standard interface. Availability and Customer Support
COMET OCTAL and COMET TETRA will be sampling in the fourth quarter
of 2005. Both devices are packaged in a dense 17mm by 17mm, 256
ball PBGA, and characterized for industrial temperature range
operation (-40 to +85 degrees Celsius). These devices are also
available in RoHS compliant lead-free packaging. To minimize design
time and development resources, a comprehensive COMET OCTAL and
COMET TETRA applications solution package is available at
http://www.pmc-sierra.com/networking. The applications package
includes datasheets, a technical overview and hardware design
recommendations. The PM2358-KIT COMET OCTAL Evaluation Kit will be
available in the first quarter of 2006, including an evaluation
card with full documentation and software. For more information,
