STS-1 soft core

Synthesizable soft STS-1 framer core used in SONET at 51.84 Mbps

STS-1 is the basic signal of SONET system working at 51.84 Mbps. It is able to transport the SONET and non-SONET signals by the use of Virtual Tributaries. In the current project the DS-1 data is multiplexed, which is called VT structured STS-1 SPEbecause it is floating in nature. Moreover the system overhead bytes are designed.

NOTE: This project is included as a part of the OpenStacks initiative, Indian Institute of Technology Delhi Department of Electrical Engineering/Optoelectronics and Optical Communication Program. Please visit http://www.iitd.ac.inee and http://paniit.iitd.ernet.in~optoelectronics
