STS-12 ATM/DS3 SONET MAPPER
Features
Processes valid combinations of SONET/SDH STS-12c/AU-4-4c, STS-3c/AU-4, or STS-1 tributaries within an STS-12/STM-4. Terminates and generates SONET/SDH section, line, and path layers. Provides DS3 mapping and demapping for 12 STS-1s and supports clear channel DS3. Supports ATM payload mapping into STS-12c/AU-4-4c & STS-3c/AU-4, as well as direct ATM or ATM PLCP for DS3 tributaries. Supports M23 and C-Bit parity clear channel DS3 mapping, as well as clear channel DS3 transparent passthrough mode. Provides a 77.76 MHz 8-bit bus interface on the SONET/SDH side in both the TX and RX directions. Provides a 50 MHz 16-bit Utopia Lvl 2 interface on the system side in both the TX and RX directions. Programmable Utopia addresses to support multi-PHY operation. Generic 8-bit microprocessor interface for configuration and status monitoring. Supports IEEE 1149.1 JTAG testing. Packaged in a 388 pin BGA. Implemented in 3.3V with 5V tolerant I/O. Loopback capability for SONET/SDH, DS3 and ATM.
SUMMARY DATASHEET
General Description
The S1202 is a highly integrated chip that implements SONET/SDH processing and ATM mapping functions for STS-12/STM-4 data streams. In addition, it supports DS3 tributaries, in an STS-1 SPE, with provisionable support for M23 or C-bit parity OH, as well as clear channel pass-through, direct mapping of ATM cells, or ATM PLCP mapping. The S1202 is SONET and SDH standar……
