Z3[7:0]:
The Z3[7:0] bits are inserted in the Z3 byte position when the SRCZ3 bit of the THPP Source
& Pointer Control Register is logic 0 and input TPOHEN is low during the path Z3 growth bit
positions in the path overhead input stream, TPOH.
This field is only valid for THPP STS-1/STM0 #1.
F2[7:0]:
The F2[7:0] bits are inserted in the F2 byte position when the SRCF2 bit of the THPP Source
& Pointer Control Register is logic 0 and input TPOHEN is low during the path User Channel
bit positions in the path overhead input stream, TPOH.
This field is only valid for THPP STS-1/STM0 #1.
