Receive SS Drop Values.
SS bit values from
the four selected ports.
Reserved.
These bits must be written to their
reset default value (00).
Receive Pointer Interpretation Hardware
State[Bits 1
—
6].
Software access to the 48
STS-1 PI state values. 00 = Normal;
01 = Concat; 10 = LOP; 11 = AIS.
Reserved.
These bits must be written to their
reset default value (0x0).
Receive Pointer Interpretation Hardware
State[Bits 7
—
12].
Software access to the 48
STS-1 PI state values. 00 = Normal;
01 = Concat; 10 = LOP; 11 = AIS.
Transmit RDI-P State.
State bits indicating the
value of the inserted RDI-P value.
Reserved.
These bits must be written to their
reset default value (000000).
Receive RDI-P Data Monitor State.
State bits
indicating the value of the G1[3:1] bits.
Receive Unequipped C2 Value State.
State
bit indicating an unequipped value (0x00) has
been detected in the C2 byte.
Receive Path Payload Label Mismatch State.
State bit indicating a mismatch occurred
(logic 1).
Receive Signal Degrade State Bit.
State bit
indicating the state of the BER algorithm.
0 = within BER programmed, 1 = exceed BER
threshold programmed.
Receive Signal Fail State Bit.
State bit
indicating the state of the BER algorithm.
0 = within BER programmed, 1 = exceed BER
threshold programmed.
Receive F2 Byte Data Monitor.
State byte
indicating the value of the validated F2 byte.
Receive C2 Data Monitor.
State byte holding
the accepted value for the monitored C2 byte.
