Agilent Technologies has introduced a new HDMP-3001 Ethernet over SONET (EoS) mapper chip. This application specific standard product (ASSP) enables both local area network (LAN) and wide area network (WAN) ports to exist over SONET/SDH networks.
The Agilent HDMP-3001 is part of a joint development project with the Wuhan Post and Telecommunications Institute in Wuhan, China and is the first in a family of new SONET compliant multi-protocol ICs (MPICs).
MPICs take protocol independent traffic and map it into SONET, providing a solution for loading Enterprise data traffic onto a SONET Metro infrastructure. The new chip is claimed to be the first solution to provide full-duplex mapping of Ethernet frames encapsulated into SONET/SDH payload using either the generic framing procedures (GFP) or the link access procedure-SDH (LAPS) protocol.
The HDMP-3001 EoS mapper is for use with Ethernet WAN switch ports, standalone data service unit/channel service unit (DSU/CSU) systems and line cards for SONET add drop multiplexers (ADM) within the LAN and metropolitan access (edge) network. The edge network is where the carrier-owned WAN meets the corporate-owned LAN.
Agilent intends to offer additional MPIC products that will address SONET data rates up to 2.5 Gb/s and a variety of protocols including Ethernet, Fibre Channel and Packet over SONET, as well as value-added services such as digital video broadcast.
A second EoS mapper is expected to sample in Q1 2002, supporting the OC-48/STM-16 (2.5 Gb/s) standard.
The Agilent HDMP-3001 EoS mapper device is available in production volumes and is priced under $50 in 50,000 unit quantities. The HDMP-3001 is supplied in a 160-pin plastic quad flat pack (PQFP) package and supports the OC-3/STM-1 (155 Mb/s) standard. A developer’s kit, including development board, schematics and instructions, will be available in February 2002 priced at $3,500.
