•
<dslport>
- The DSL-port to configure. The parameter
<a.b.c>
refers to the ECN port (
a
), the ESN108 port (
b
) and the IP DSLAM
line (
c
).
•
bandwidth downstream/upstream –
Downstream and up-
stream bandwidth.
•
pvc <pvc>
- Configure the specified PVC number. Range 1-8.
•
max-burst-size <size> –
defines the maximum number of
ATM cells allowed in one burst at Peak Cell Rate. The number of
cells should be set according to the size of the packets that should
be transferred. Note when calculating the number of cells needed,
that the payload of an ATM cell is 48 byte. Range 1-65535.
•
peak-cell-rate <speed> -
Setting the maximum speed at-
tainable in traffic bursts through the PVC. Range 0-32768. It is
used to limit the absolute bandwidth used by the PVC. The traffic in
the PVC can never exceed the Peak Cell rate. The Peak Cell rate
should be equal to, or greater than the Sustainable Cell Rate.
•
sustainable-cell-rate <speed> -
Setting the average
speed through the PVC. Range 0-32768. When Telephony over IP
is used, a minimum of 170 kbps per channel is needed, and as the
value must be a multiple of 32 kbps a value of 192 kbps must be
specified. If two voice channels are used the
Sustainable Cell
Rate should be set to 352 kbps. If no value is entered the value will
be set to zero, which means that the PVC will not be created. The
units of this parameter are kbps (1.000 bits per second).
Default Settings

Command Usage
This command is used to set the bandwidth of the PVC for a service defin-
ing the Peak Cell Rate, Sustainable Cell Rate and the Maximum Burst Size.
When ATM service class is set to ubr or cbr, Sustainable Cell Rate and
Maximum Burst Size is not used.
