Signal Name:
Signal Description:
Signal Type:
This signal determines whether the DS3112 will operate in either the T3 mode or the E3 mode. It acts as a
global control bit for the entire DS3112. This signal should be set into the proper state before a hardware
reset is issued via the RST signal. This input is coupled with the G.747E input to create a special test
mode whereby all the outputs are tri-stated
