MARS2G5 T-LT (TSOT042G52) SONET/SDH 155/622/2488 Mbits/s Overhead and Path Processor Product Brief May 2003 Description The MARS2G5 T-LT SONET/SDH overhead and path processor provides a versatile solution for quad OC-3, quad OC-12, and for single OC-48 linear and ring datacom/telecom applications. Constructed using COM2 CMOS modular process, this device incorporates integrated SONET/SDH section/line/path termination, pointer processing, and cross connect blocks. Communication with the MARS2G5 T-LT device is accomplished through a generic microprocessor interface. The device supports separate address and data buses. With this device, support for different types of applications for OC-3/OC-12/OC-48 data equipment is possible, enabling dramatic system cost reduction and the ease of development of extremely competitive solutions. The interface rates supported are STS-48/STM-16, quad STS-12/STM-4, and quad STS-3/STM-1. The concatenation levels supported by this device are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-15c, . . . , STS-45c, and STS-48c.
