Signal Name:
FRLOS
Signal Description:
T3/E3 Receive Framer Loss Of Signal
Signal Type:
Output
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 5.3 for details on the set and clear criteria for this signal. LOS status is also available via a
software bit in the T3/E3 Status Register (Section 5.3).
Signal Name:
FRLOF
Signal Description:
T3/E3 Receive Framer Loss Of Frame
Signal Type:
Output
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 5.3 for details on the set and clear criteria for this signal. LOF status is also available via a
software bit in the T3/E3 Status Register (Section 5.3).
