TXC04226 Overview
The EtherMap™-3 is a highly integrated device that provides for mapping of 10/ 100/1000 Mbit/s Ethernet into SONET/SDH STS-3/STM-1 Transport payloads. The device supports connection for up to eight 10/100 Mbit/s Ethernet ports, using SMII interfaces, or a single 1000 Mbit/s Ethernet port, using a GMII interface. In the transmit direction, for each port, received Ethernet frames are encapsulated using either GFP,...
