OC-12/3 Ethernet Over PDH/SONET Mapper Lite

he AT1240 provides a multi-format and multi-rate Ethernet and common legacy data over PDH, PDH mapped to SONET SDH or direct SONET mapping. On the PDH side, the chip provides a parallel multiplexed PDH bus carrying 3 DS3s or 3 E3s or 84 DS1s or 63 E1s or any mixture of them. A simple FPGA is used to convert parallel DS1/E1/DS3/E3 signals on the PDH bus to the serial signals required for the LIUs for pin count expansion. The 84DS1/63E1s signals CAN be accessed directly on the PDH bus or be multiplexed to 3 channelized DS3/E3s via 3 embedded M13/E13 engines or mapped to SONET SDH By Arrive Technologies, Inc.
