The AT1230 is a highly integrated OC-12/STM-4 or OC-3/STM-1 Add/Drop Multiplexer and PDH Mapper on a chip. The AT1230 has integrated
cross-connects supporting DS0, VT/TU/TU3 and STS/VC level switching. On the SONET/SDH side, the chip provide 4 OC-12/STM-4 and 4 OC-
12/3/STM-4/1 interfaces with on-chip CDR. 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. The chip supports SONET/SDH interface with 1+1
protection, UPSR and mapping of DS1/E1/DS3/E3 to SONET/SDH. The AT1230 includes flexible channel assignment for all applicable SDH and
SONET mappings.
