VBR_rt
or
VBR_nrt.
VBR (Variable Bit Rate) is used for bursty traffic and
bandwidth-sharing with other applications. VBR_rt (real time) is more time-
sensitive than VBR_nrt (non-real time), and VBR_rt is typically used for voice
and video traffic.
Notes:
If the QoS Type setting is CBR, then the Scr Rate and Max Burst Size settings
are not configurable.
If the QoS Type setting is UBR, then the Pcr Rate, Scr Rate, and Max Burst
Size settings are not configurable.
If the QoS Type setting is VBR-rt or VBR-nrt, set the appropriate Pcr Rate,
Scr Rate, and Max Burst Size values.
Note
: The values entered are interpreted as ATM Cells per second (cps).
3
If required by your service provider, enter a rate in the
PCR Rate
field.
Note
: The Peak Cell Rate (PCR) is the maximum allowable rate at which cells can
be transported. Enter the rate in the field (if required by your service provider).
4
If required by your service provider, enter a rate in the
SCR Rate
field.
Note
: The Sustainable Cell Rate (SCR) sets the average cell rate that can be
transmitted. The SCR value is normally less than the PCR value. Enter the rate in
the field ( provider).
5
For the
Max Burst Size
, enter the number of contiguous (ATM) cells allowed to
be send in one burst.
6
For the
Autodetect
, select
Enable
to have the settings automatically entered, or
select
Disable
to enter the values manually.
Note
: Autodetect requires
a PVC value which is part of the “pre
-configured
range” of default PVCs
being 0/35, 8/35, 0/43, 0/51, 0/59, 8/43, 8/51, and
8/59. Other values will not be autodetected and should be entered manually.
7
Enter the settings provided by your service provider for each of the following
Virtual Circuit
settings:
VPI (Virtual Path Identifier)
VCI (Virtual Channel Identifier).
8
For the
DSL Modulation
, select the appropriate mode from the list of available
options; then, click
Save Modulation
to save the modulation setting.
