Name
Description
Fwd SECB Lost (8)
Bwd SECB Lost (8)
Severely Errored Cell Block Lost Cells. When CLP0_SECBs_Only is a logic 0, the
SECB Lost is incremented whenever the number of Lost CLP0+1 cells exceeds
MLOST in the selected threshold register. When CLP0_SECBs_Only is a logic 1,
SECB Lost is incremented whenever the number of Lost plus Tagged CLP0 cells
exceeds MLOST. The accumulation of SECB Lost inhibits the accumulation of the
count of Lost CLP0 and Lost CLP0+1 cells.
Fwd SECB
Misinserted (8)
Bwd SECB
Misinserted(8)
Severely Errored Cell Block Misinserted Cells (CLP0+1). The SECB Misinserted is
incremented whenever the number of Misinserted cells exceeds MMISINS in the
selected threshold register. The accumulation of SECB Misinserted inhibits the
accumulation of the count of Misinserted Cells.
Fwd SECBC (8)
Forward Severely Errored Cell Blocks Combined. This running counter increments
each time a SECB is declared. This value is inserted into the SECBC field of
generated Backwards Reporting cells.
Bwd SECBC (8)
Backward Severely Errored Cell Blocks Combined. This value is copied from the
SECBC field of received Backwards Reporting cells, and represents a rolling
modulo-256 count of all Severely Errored Cell Blocks. There is no need to initialize
this running counter.
Bwd SECBC
Accum. (8)
Backward Accumulating SECBC Count. Whenever a received Bwd PM cell has a
SECBC field different from the stored Bwd SECBC, this field is incremented by the
modulo-256 difference. This is a saturating counter that initializes itself when the
first Bwd PM cell is received.
Fwd Lost Fwd PM
Cells (8)
The Fwd Lost Fwd PM Cells count uses the MCSN of received Forward Monitoring
cells to determine the number of lost Fwd PM cells. Whenever the MCSN of a
received Fwd PM cell is out of sequence, this count is incremented by the difference
between the expected and received MCSN, and BIP-16 calculations are
suppressed.
Fwd Tagged CLP0
Cells (16)
Bwd Tagged CLP0
Cells (16)
Whenever there are less CLP0 cells received than were transmitted (TUCD is
negative) then those cells have either been lost or tagged. The inference is made
that if CLP0 cells were lost, then they should be lost from the CLP0+1 stream as
well. Thus when TUCD0 < 0, the Lost CLP0 cells count is incremented by the lesser
of –TUCD0 and -TUCD0+1, and the Tagged CLP0 Cell Count is incremented by (-
TUCD0) – (-TUCD0+1), so long as the result is positive. This count is not
incremented if the SECB Lost or SECB Misins count is incremented.
Fwd Lost CLP0
(16)
Bwd Lost CLP0
(16)
The Lost CLP0 Cell Count represents the total number of Lost CLP0 user cells
during a PM session. The Lost CLP0 cell count is incremented by the lesser of -
TUCD_0 and –TUCD_0+1, whenever that number is greater than zero. This count is
not incremented if the SECB Lost count is incremented.
Fwd Lost CLP0+1
(16)
Bwd Lost CLP0+1
(16)
The Lost CLP0+1 Cell Count represents the total number of Lost CLP0+1 user cells
during a PM session. The Lost CLP0+1 cell count is incremented by the number of
Lost CLP0+1 cells, whenever TUCD_0+1 < 0 . This counter will not increment is the
SECB Lost counter increments (it is therefore sensitive to CLP0_SECBs_only).
Fwd Misinserted
Cells (16)
Bwd Misinserted
Cells (16)
The Misinserted Cell Count represents the total number of Misinserted CLP0+1 user
cells during a PM session. The Misinserted Cell Count is incremented by the
number of misinserted CLP0+1 cells, whenever MMISINS
≥
TUCD_0+1 > 0. (i.e. this
count is not incremented if the SECB Misinserted Count is incremented).
Fwd Total Lost
CLP0+1 (16)
Bwd Total Lost
CLP0+1 (16)
The Total Lost CLP0+1 cell count represents the total number of lost CLP0+1 user
data cells during a PM session. This count is not dependent on a threshold. That
is, the Total Lost CLP0+1 cell count is always incremented by the number of lost
CLP0+1 user cells.
