where service-type can be UBR, CBR, VBR or RTVBR. For the UBR and CBR traffic, it is possible to specify a
PCR value (Peak Cell Rate), while for VBR and RTVBR is possible to specify, in addition to PCR, the values for
SCR (Sustainable Cell Rate) and MBS (Maximum Burst Size), in the following way:
set adsl pvc atm0|…|atm7 pcr <value>
set adsl pvc atm0|…|atm7 scr <value>
set adsl pvc atm0|…|atm7 mbs <value>
The value provided for PCR and SCR is expressed in cells / sec, while the value for MBS is expressed in
bytes. To remove the options set:
set adsl pvc atm0|…|atm7 no-service
set adsl pvc atm0|…|atm7 no-pcr
set adsl pvc atm0|…|atm7 no-scr
set adsl pvc atm0|…|atm7 no-mbs
It is possible to vary the length of the transmission queue on the interface associated with the pvc, in the
following way:
set adsl pvc atm0|…|atm7 qlen <value>
To remove the options set:
set adsl pvc atm0|…|atm7 no-qlen
You can set the router so that it can send the Loopback (F4/F5) OAM cells on a particular PVC. In case there
is no reply, the PVC is put on a down state.
set adsl pvc atm0|…|atm7 oma-manage [interval N]
It is also possible to put down a specified PVC manually, using the command:
set adsl pvc atm0|…|atm7 shut
To set the mode of the standard ADSL line you can use the set command-line ADSL mode, which assumes
different options depending on the model of Imola.
On Imola XX10, the options can be: ITU (Europe), ANSI and AUTO (Multimode):
set adsl line-mode itu|ansi|auto
On Imola XX20, the options can be a combination of the possible ADSL standards, like:
set adsl line-mode ADSL2 | ADSL2+/ADSL2/G.DMT/T1.413 | ADSL2 AnnexM | ADSL2/G.DMT | ADSL2+/ADSL2 | G.DMT | ADSL2+/ADSL2/G.DMT | T1.413
To remove the options set:
set adsl no-line-mode
It is also possible specify a description of the ADSL interface, which will be given back by the SNMP agent
(if configured and active) by querying the Mib_II ifDescr variable with the following commands:
set adsl description|no-description <value>
To remove the options set:
set adsl no-description
set adsl pvc atm0 no-description
Here follows an example of a valid sequence of commands to configure the ADSL interface:
set ADSL encap rfc1483-llc
set ADSL pvc-number 1
set ADSL description muxadsl
