Abstract :
A four channel DS1 framer chip has been developed for deployment in multichannel T1 systems, SONET add-drop multiplexers, T3 multiplexes, and ATM over T1 applications. Area reduction was realized through the use of a high speed clock, permitting use of shared resources and construction of simple arbiters for single port RAM. For further gate reduction, a state-machine based framing algorithm utilizing RAM as next state memory was developed
