Network Elements' LiASIC, the industry's first 10Gb/s multi-
protocol processor, previously available only in the award-
winning LiMPM module, is now available as an independent
ASIC product. The LiASIC is designed to support 10Gb/s
SONET/SDH OC-192/STM-64, 10Gb/s Packet-over-SONET
(POS), 10 Gigabit Ethernet (10GbE) LAN, 10GbE WAN, and
Ethernet-over-SONET (EOS) optical networking applications.
Network Elements' LiASIC is set apart from the competition by
rich multi-protocol processing, low power dissipation (typically
<7 watts), advanced packet filtering, and flexible SONET
overhead processing. The LiASIC incorporates an OIF SPI-4
phase 2 interface for transferring system-side packets, an OIF SFI-4/802.3 XSBI
interface for connecting to PHY modules, an 802.3 XGMII interface for connecting to
PCS/PMD modules, and a 16-bit control interface.
In SONET mode, the LiASIC provides full section and line termination for
concatenated or channelized streams. In POS mode, the LiASIC additionally
provides PPP/HDLC encapsulation and supports packets up to 64KB. Configured for
10GbE, the LiASIC provides MAC, 64/66 PCS and WIS functionality. In all packet
modes, the LiASIC offers advanced packet filtering and built-in-test features.

To speed the time-to-market, Network Elements offers the industry's most
comprehensive Application Programming Interface (API) for use with the LiASIC.
The API, written in ANSI C for maximum portability, provides a high-level
interface to the ASIC's functionality, eliminating the need for designers to learn the
complexities of bit-level assignments.
