Pointer Adjustment
RX Pointer Adjustment
Pointer Value
For STS/AU: 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 VT/TU: 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
.
Ptr. Incr.
(Pointer Increment) gives statistics on positive pointer
adjustment detected.
Ptr. Decr.
(Pointer Decrement) gives statistics on negative pointer
adjustment detected.
NDF
(New Data Flag) gives statistics on pointer jumps containing a
New Data Flag.
For STS/AU: Bits 1 to 4 of the pointer word (H1 and H2) detected are
“1001”.
For VT/TU: Bits 1 to 4 of the pointer word (V1 and V2) detected are
“1001”.
No NDF
(No New Data Flag) gives statistics on normal pointer jumps
containing no NDF.
For STS/AU: Bit 1 to 4 of the pointer word (H1 and H2) detected are
“0110”.
For VT/TU: Bit 1 to 4 of the pointer word (V1 and V2) detected are
“0110”.
