Signal Name:
Signal Description:
Signal Type:
This signal will be forced high when the receive T3/E3 framer is in a Loss Of Signal (LOS) state. It will
remain high as long as the LOS state persists and will return low when the framer exits the LOS state. See
Section
software bit in the T3/E3 Status Register (Section 5.3).
Signal Name:
Signal Description:
Signal Type:
This signal will be forced high when the receive T3/E3 framer is in a Loss Of Frame (LOF) state. It will
remain high as long as the LOF state persists and will return low when the framer synchronizes. See
Section
software bit in the T3/E3 Status Register (Section 5.3).
