General Description:

The DS33M30 family of products provides a compactand efficient solution for transporting Gigabit Ethernettraffic over OC-3/STM-1 optical networks. With theaddition of an optical transceiver, Ethernet PHY,DDR SDRAM, and host processor, a completesolution of GbE over OC-3/STM-1 can beimplemented. The family supports Ethernet overSONET/SDH (EoS) at VC-4, “Next-Generation” EoShigh-order mapping with multiple concatenatedVC-3s, and Ethernet over PDH over SONET/SDH(EoPoS) with up to three virtually concatenatedDS3/E3 tributaries. The supported frameencapsulations include GFP-F, HDLC, cHDLC, andX.86 (LAPS).

Features:

♦ Support for EoS in One STS-3c/VC-4, EoSOver Up to Three Concatenated STS-1/VC-3s,and EoPoS Over Up to Three ConcatenatedDS-3s
