DS33M30/DS33M31/DS33M33

Ethernet Over SONET/SDH Mapper

________________________ General Description

The DS33M30 family of products provides a compact

and efficient solution for transporting Gigabit Ethernet

traffic over OC-3/STM-1 optical networks. With the

addition of an optical transceiver, Ethernet PHY,

DDR SDRAM, and host processor, a complete

solution of GbE over OC-3/STM-1 can be

implemented. The family supports Ethernet over

SONET/SDH (EoS) at VC-4, “Next-Generation” EoS

high-order mapping with multiple concatenated

VC-3s, and Ethernet over PDH over SONET/SDH

(EoPoS) with up to three virtually concatenated

DS3/E3 tributaries. The supported frame

encapsulations include GFP-F, HDLC, cHDLC, and

X.86 (LAPS).
