In the news release, Light Reading Insider Analyzes Next-Gen Sonet/SDH Chips,
issued yesterday, July 6, by Light Reading, Inc. over PR Newswire, we are
advised by the company that the third key finding in the sixth graph should
read "Several framer/mapper devices, such as the Arrive AT-1300 and PMC-Sierra
PMC5337 ... " rather than "Several framer/mapper devices, such as the Arrive
AT-1300, Intel IXP2500, and PMC5337 ..." as originally issued inadvertently.
Complete, corrected release follows:



NEW YORK, July 6  /PRNewswire/ -- Multiservice edge equipment based on tightly
integrated, next-gen Sonet/SDH silicon has radically improved carriers' ability
to offer packet services over legacy infrastructure.

Encouraged by this success, chip makers and equipment manufacturers are now
extending their activities to smaller, less-expensive access products, finds
the new Next-Gen Sonet/SDH Chip Survey from Light Reading Insider
(http://www.lightreading.com/insider).

"The access market is very active," says the report's author, Simon Stanley.
"Driven by the demand from system OEMs, vendors are introducing new devices at
155 Mbit/s, 622 Mbit/s, and 2.5 Gbit/s with support for low-order virtual
concatenation."

This focus on access is a lead indicator of the buzz set to emerge around
so-called "micro MSPPs" (multiservice provisioning platforms), being developed
to help carriers extend their infrastructure closer to their customers and
consolidate services into a single pipe.

Light Reading Insider's Next-Gen Sonet/SDH Chip Survey is based on a detailed
survey of 31 next-gen Sonet/SDH silicon products from the ten major suppliers
in the market.

  Key findings include:

   -- PMC-Sierra was among the first companies to identify the importance of
      next-gen Sonet and is now perceived as a leader.

   -- Only three vendors include transparent GFP functionality in their
      devices.

   -- Several framer/mapper devices, such as the Arrive AT-1300 and
      PMC-Sierra PMC5337, now integrate the core of a multiservice ADM in a
      single device.

   -- The latest devices from Agere, Arrive, and Infineon support 128 VCAT
      groups, setting a new feature bar.

   -- There is major debate about which vendors have fully interoperable and
      hitless Link Capacity Adjustment Schemes (LCAS).



Silicon vendors analyzed in this report: Agere Systems Inc. (NYSE:AGR.A);
Applied Micro Circuits Corp. (NASDAQ:AMCC); Arrive Technologies; Cypress
Semiconductor Corp. (NYSE:CY); Galazar Networks Inc.; Infineon Technologies AG
(NYSE/Frankfurt: IFX); Intel Corp. (NASDAQ:INTC); PMC-Sierra Inc. (NASDAQ:
PMCS); TranSwitch Corp. (NASDAQ:TXCC); and Vitesse Semiconductor Corp.
(NASDAQ:VTSS).
