Defect/ Alarm Generation
LOS: 9.95238 Gb/s output is forced to all zeros for a user selected time, from 1 to 15
microseconds with a resolution of 1 microsecond or continuously.
LOF, SEF: All of the A1 and A2 bytes of the 9.95238 Gb/s output are inverted for a user-selected
time.
AIS-L (MS-AIS): The Line OH (Multiplex Section OH) and the entire SPE are set to all ones for
a user-selected time.
RDI-L (MS-RDI): The '110' code is set in the three least significant bits of the K2 byte for a user-
selected time.
LOP (HP-LOP) sets the H1/H2 pointer bytes to 63/0F for SONET and 6B/0F for SDH. This
equates to a pointer value of 783, which is over the maximum allowable pointer value of 782.
AIS-P (HP-AIS) forces all ones into the H1/H2/H3 bytes and the entire SPE.
RDI-P (HP-RDI) has four different defect types. The RDI-P defect forces the G1 byte bits 4-1 to
the following values:
“one bit” RDI-P: ‘100’
Enhanced RDI-P Payload: ‘010’
Enhanced RDI-P Server: ‘101’
Enhanced RDI-P Connectivity: ‘110’
For all Defects except LOS, the time is selected in frames, up to 240000, or continuous.
