For HOP: Displays the value for the pointer, H1 and H2, indicating
the offset in bytes between the pointer and the first byte of the
STS-n (SONET) or AU-n (SDH).

For LOP: Displays the value of the pointer, V1 and V2, indicating the
offset in bytes between the pointer and the first byte of the VTn
(SONET) or TU-n (SDH) of the high order path. However, TU-3
considered a low order path, uses the H1, H2, H3 bytes for its
location.

Cumulative Offset indicates the difference between the pointer
increment and the pointer decrement. A pointer jump will reset this
value to 0.
