54 IQ Probe User Manual 61200214L1-1
Chapter 7. Configuring the DCE Port
Only PVCs that are used in DBU should have the DBU DLCI set to a
non-zero value.
The range for the DBU DLCI field is from 16-1007. Therefore,
you cannot manually enter 0 for the PVCs not used in DBU.
When an entry is first created with the ADD selection, it is set to
0 by default. To reset a previously configured DBU DLCI to 0,
delete the entry and then add it back in (using the Delete and
Add selections/keys).
CIR (Kbps)
Enter the CIR (committed information rate) in kbps for the
corresponding DLCI. The information is supplied by your
service provider and must be entered for each PVC to ensure
accuracy of statistical information.
Seq Num Checking (SEQ #)
Set to ENABLE only if there are IQ products on both ends of the
PVC. When enabled, the IQ Probe tags each frame with a
sequence number which is then used by the remote IQ device to
detect lost packets. Lost packet counts are given in the Statistics
menus.
Delay Measurement (PVC DELAY)
Set to ENABLE only if there are IQ products on both ends of the
PVC. When enabled, the IQ Probe periodically transmits a
loopback frame to the remote IQ device which is then returned
to measure round trip delay of each PVC. Minimum, maximum,
and average delay measurements are given in the Statistics
menus.
