Reset default of registers 0x0AA6, 0x0AAE, 0x0AB6, 0x0ABE = 0xF200.
Reset default of registers 0x0AA7, 0x0AAF, 0x0AB7, 0x0ABF = 0x0000.
Reset default of registers 0x0AA8, 0x0AB0, 0x0AB8, 0x0AC0 = 0x0FFF.

* SS pointer interpretation algorithm is not implemented.
These bits maintain the validated J1 byte, place 0x0000 into all other POH bytes, and invalidate the received payload so that no data is passed
through the DE. These bits do not affect the transmit path and do not affect the transmitted G1 byte.

Receive J1 Dump Control.
Control bit, when set
to a logic 1, causes the device to store the J1 byte
of the selected STS-1 time slot.
Reserved.
This bit must be written to its reset
default value (0).*
Receive B3 Bit/Block Count.
Control bit, when
set to a logic 0, causes the B3 error counter to
count bit errors; otherwise, block errors are
counted.
Receive Increment/Decrement 6-or-8 Majority
Voting.
If programmed to a logic 0, uses 6 of 10
majority voting to determine a valid increment or
decrement; otherwise, uses 8 of 10 majority voting.
Reserved.
These bits must be written to their reset
default value (00).
Remote Defect Indication Enhanced or 1-Bit
Monitoring.
Control bit, when set to a logic 1,
causes the RDI-P to detect G1[3:1] bits for an
enhanced failure code; otherwise, monitors G1[3]
for a 1-bit code.
Receive FORCE_LOP.
Control bits, when set to a
logic 1, force the associated time slot into the LOP
state; otherwise, does nothing.
Concatenation Indication Expected.
Control bits,
when set to 0 = do
not
expect associated time slot
to be in CONC mode; otherwise, expect CONC
mode.
