0 = Do not insert error.
1 = Insert error for number of frames in register 0x3000C.
The error insertion is based on a rising edge detector. As
such, the control must be set to value 0 before trying to
indicate a second A1, A2 corruption
0 = Do not insert error
1 = Insert error marked in register 0x3000F.
The error insertion is based on a rising edge detector. As
such, the control must be set to value 0 before trying to ini-
tiate a second B1 corruption.
0 = B1 is inserted in the transmit direction by the SONET
block
1 = B1 is not inserted in the transmit direction
0 = A1/A2 is inserted in the transmit direction by the
SONET block
1 = A1/A2 is not inserted in the transmit direction
The value 1 in any bit location indicates that STS# is in
CONCAT mode.
0 = Not in concatenation mode or is the head of concate-
nated group
1 = indicates the channel is concatenated
The value 1 in any bit location indicates that STS# is in
CONCAT mode.
0 = Not in concatenation mode or is the head of concate-
nated group
1 = indicates the channel is concatenated
Set when any of the alarms in the channel alarm register
(0x30028) are set and the alarm is enabled. This alarm is
enabled in 0x30027 bit 0 for channel AA etc.
Set when any alarm for AIS-P is set and the corresponding
enable is set.
Set when the elastic store in the pointer mover write and
read address is within 1 byte. Alarm enable is 0x30027 bit
