tracks statistics for a limited number of the PVCs that pass through.
This number is determined in the M

field (see
Maximum PVC Count on page 7-5). The three choices for this field
are described below:

a PVC as second priority to a PVC set to E
NABLED
.
Enabled
If set to E
NABLED
, then statistics will be logged for this PVC if the
M
AX
PVC C
OUNT
has not been exceeded. A PVC set to E
NABLED
is
designated as a higher priority than one set to A
UTO

any time.
If the TSU IQ+ encounters a PVC that has not been entered into the PVC

PTIONS
table, the PVC is set to A
UTO
by default.
