OC-12/3 Ethernet Over PDH/SONET Mapper

The AT1250 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 12 DS3s or 12 E3s or 336 DS1s or 252 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 336DS1/252E1s signals CAN be accessed directly on the PDH bus or be multiplexed to 12 channelized DS3/E3s via 12 embedded M13/E13 engines or mapped to SONET SDH By Arrive Technologies, Inc.
