PT Registers
Table 103. Registers 0x0AA6—0x0AAD, 0x0AAE, 0x0AB5, 0x0AB6—0x0ABD, 0x0ABE—0x0AC5: PT Control
Reset default of registers 0x0AA6, 0x0AAE, 0x0AB6, 0x0ABE = 0x1200.
Reset default of registers 0x0AA7, 0x0AAF, 0x0AB7, 0x0ABF = 0x0000.
Reset default of registers 0x0AA8, 0x0AB0, 0x0AB8, 0x0AC0 = 0x0FFF.
Reset default of registers 0x0AA9, 0x0AB1, 0x0AB9, 0x0AC1 = 0x0000.
Reset default of registers 0x0AAA, 0x0AB2, 0x0ABA, 0x0AC2 = 0x0000.
Reset default of registers 0x0AAB, 0x0AB3, 0x0ABB, 0x0AC3 = 0x1AAA.
Reset default of registers 0x0AAC, 0x0AB4, 0x0ABC, 0x0AC4 = 0x3AAA.
Reset default of registers 0x0AAD, 0x0AB5, 0x0ABD, 0x0AC5 = 0x3333.
* 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
0AA6, 0AAE,
0AB6, 0ABE
through the DE. These bits do not affect the transmit path and do not affect the transmitted G1 byte.

Receive POH Monitor Select. Control bit selects which
of the 12 time-slot POH bytes are monitored in the
associated data stream. A total of four
STS-Nc streams can be monitored at any one time.
Only values from 0001 (time slot 1) to 1100
(time slot 12) are valid. For quad OC-3 and quad OC-12
mode, use the default value 0001.
Reserved. These bits must be written to their reset
default value (00).
Receive Concatenation State: Use All STS-1 Time
Slots or Just the First One. If set to 1, all STS-1 time
slots are used. If set to 0, a higher level state machine
(CONC) is used to process the individual states from
the associated time slots. The higher-order state
machine is defined as follows.

LOPX
* States INCX, DECX, and NDFX are considered the same as
Receive J1 Frame Algorithm. Control bits, when set to
00 or 11 = no framing; 01 = SONET framing; 10 = SDH
framing.
