Received Data Odd/Even Parity Check.
If 0 odd parity
check for received data, if 1 even parity check.
J1 Monitoring Mode.
There are four monitoring modes
as defined in the document.
Receive ERDI Mode.
When 1, 3-bit enhanced ERDI
mode is supported; when 0, the 1-bit RDI mode is
supported.
G1 Error Count in Bit or Block.
When 0, G1(7:4) check
logic will count bit errors; otherwise, it counts block errors.
B3 Error Count in Bit or Block.
When 0, B3 check logic
will count bit errors; otherwise, it counts block errors.
Receive POAC Odd or Even Parity Insert.
When 1, the
output POAC parity bit is even; otherwise, the parity is
odd.

SPE_8ORMAJORITY
TU-3 Pointer Interpreter Mode Control.
When 1, the
pointer interpreter transitions into the INC and DEC states
based on 8 of the 10 I and D bits. Otherwise, the pointer
interpreter transitions into the INC and DEC states based
on majority rule.

SPE_PAISINS
Path AIS Software Insertion.
When 1, path AIS insertion
is enabled.
6
SPE_PAIS_AISINH
Path AIS State bit Inhibit Signal for Generating Path
AIS.
When 1, the inhibit is on.
5
SPE_PAIS_LOPINH
Loss of Pointer Inhibit Signal for Generating Path AIS.
When 1, the inhibit is on.
4
SPE_PAIS_SFB3INH
Signal Fail Inhibit Signal for Generating Path AIS.
When 1, the inhibit is on.
3
SPE_PAIS_SDB3INH
Signal Degrade Inhibit Signal for Generating Path
AIS.
When 1, the inhibit is on.
2

SPE_PAIS_PLMINH
Path Label Mismatch Inhibit Signal for Generating
Path AIS.
When 1, the inhibit is on.
0
SPE_PAIS_TIMINH
