packets. Lost packet counts are given in the STATISTICS menus.
Choices: DISABLED or ENABLED.
Delay Measurement (PVC DELAY)
Set to ENABLE only if there are TSU IQ+s on both ends of the PVC.
When enabled, the TSU IQ+ periodically transmits a loopback
frame to the remote TSU IQ+ which is then returned to measure
round trip delay of each PVC. Minimum, maximum, and average
delay measurements are given in the STATISTICS menus.
Choices: ENABLE or DISABLE.
Stats Option (STATS OPT)
This option prioritizes PVCs for STATISTICS counts. The TSU IQ+
tracks statistics for a limited number of the PVCs that pass through.
This number is determined in the MAX PVC COUNT field (see
Maximum PVC Count on page 7-5). The three choices for this field
are described below:
Auto
If set to AUTO, then statistics will be logged for this PVC if the MAX
PVC COUNT has not been exceeded. The AUTO selection designates
a PVC as second priority to a PVC set to ENABLED.
Enabled
If set to ENABLED, then statistics will be logged for this PVC if the
MAX PVC COUNT has not been exceeded. A PVC set to ENABLED is
designated as a higher priority than one set to AUTO.
Disabled
If set to DISABLED, then statistics will not be logged for this PVC at
any time.
If the TSU IQ+ encounters a PVC that has not been entered into the PVC
OPTIONS table, the PVC is set to AUTO by default.
