G1[7:0]:
The G1[7:0] bits are inserted in the G1 byte position when the SRCREI and SRCRDI bits of
the Source and Pointer Control Register are high and TPOHEN is low during the path status
bit positions in the path overhead input stream, TPOH.
This field is only valid for THPP STS-1/STM0 #1.
H4[7:0]:
The H4[7:0] bits are inserted in the H1 byte position when the ENH4MASK bit of the Source
and Pointer Control Register is high and TPOHEN is low during the path multiframe bit
positions in the path overhead input stream, TPOH.
This field is only valid for THPP STS-1/STM0 #1.
