Alarms/Errors

GFP-FDI (GFP - Forward Defect Indication) is available with GFP-F.
RX: The FDI alarm is declared when CMF frame is received with an UPI
set to “0000 0100”.
TX: Generates a client FDI by setting the UPI field to “0000 0100”. Note
that the configuration of the CMF pFCS check box (see GFP-F/GFP-T on
page 90) is temporarily cleared and the UPI value changed when the
GFP-FDI alarm is selected. The CMF pFCS check box state and the UPI
value returns to their previous state/value when another alarm (other
than GFP-FDI or GFP-RDI) is selected.

GFP-RDI (GFP - Reverse Defect Indication) is available with GFP-F.
RX: The RDI alarm is declared when CMF frame is received with an
UPI set to “0000 0101”.
TX: Generates a client RDI by setting the UPI field to “0000 0101”. Note
that the configuration of the CMF pFCS check box (see GFP-F/GFP-T on
page 90) is temporarily cleared and the UPI value changed when the
GFP-RDI alarm is selected. The CMF pFCS check box state and the UPI
value returns to their previous state/value when another alarm (other
than GFP-FDI or GFP-RDI) is selected.

GFP-LOCS (GFP - CSF-Loss of Client Signal)
RX: LOCS is declared when CMF frame is received while UPI is set to
“0000 0001”.
TX: Generates a LOCS by setting the UPI field to “0000 0001”.

GFP-LOCCS (CSF-Loss of Client Character Synchronization)
RX: LOCCS is declared when CMP frame is received with an UPI set to
“0000 0010”.
TX: Generates a LOCCS by setting the UPI field to “0000 0010”.
