Z5[7:0]:
The Z5[7:0] bits are inserted in the Z5 byte position when the SRCZ5 bit of the THPP Source
& Pointer Control Register is logic 0 and input TPOHEN is low during the path Z5 growth bit
positions in the path overhead input stream, TPOH.
This field is only valid for THPP STS-1/STM0 #1.
Z4[7:0]:
The Z4[7:0] bits are inserted in the Z4 byte position when the SRCZ4 bit of the THPP Source
& Pointer Control Register is logic 0 and input TPOHEN is low during the path Z4 growth bit
positions in the path overhead input stream, TPOH.
This field is only valid for THPP STS-1/STM0 #1.
