ADSL Port Commands 11-7
<down max margin> = The maximum acceptable ADSL downstream signal/noise margin (0-
31db).
<down min rate> = The minimum ADSL downstream transmission rate (32-25000 Kbps).
The profile is a table that contains information on ADSL line configuration. Each entry in this table reflects a
parameter defined by a manager, which can be used to configure the ADSL line.
Note that the default value will be used for any of the above fields that are omitted.
The upstream rate must be less than or equal to the downstream rate.
Even though you can specify arbitrary numbers in the
profile set
command, the actual rate is always a
multiple of 32 Kbps. If you enter a rate that is not a multiple of 32 Kbps, the actual rate will be the next lower
multiple of 32Kbps. For instance, if you specify 60 Kbps for a port, the actual rate for that port will not exceed 32
Kbps, and if you specify 66 Kbps, the actual rate will not be over 64Kbps.
Please see the web configurator chapter on ADSL port setup for more information about fast/interleave mode.
The following example creates a premium profile (named gold) for providing subscribers with very high connection
speeds and no interleave delay. It also sets the upstream target signal/noise margin to 5 db, the upstream minimum
acceptable signal/noise margin to 0 db, the upstream maximum acceptable signal/noise margin to 30 db, the
upstream minimum ADSL transmission rate to 64 Kbps, the downstream target signal/noise margin to 5 db, the
downstream minimum acceptable signal/noise margin to 0 db, the downstream maximum acceptable signal/noise
margin to 30 db and the downstream minimum ADSL transmission rate to 128 Kbps.
ras> lcman port profile set adsl gold fast 800 8000 5 0 30 64 5 0 30 128
This next example creates a similar premium profile (named goldi), except it sets an interleave delay of 16 ms for
both upstream and downstream traffic.
ras> lcman port profile set adsl goldi interleave=16,16 800 8000 5 0 30 64 5 0 30 128
After you create an ADSL profile, you can assign it to any of the ADSL ports on any of the ADSL line cards in the
Integrated Ethernet Switch.
11.3.8 Delete ADSL Profile Command
Syntax:
lcman port profile delete <adsl|shdsl> <profile>
where
<adsl|shdsl>
=
ADSL or SHDSL profile.
<profile>
=
A profile name.
This command allows you to delete an individual ADSL profile by its name. You cannot delete a profile that is
assigned to any of the DSL ports on any of the line cards in the Integrated Ethernet Switch. Assign a different
profile to any DSL ports that are using the profile that you want to delete, and then you can delete the profile.
The following example deletes the gold ADSL profile.
lcman port profile delete adsl gold
