if you do not specify one. L/L

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 32 Kbps. 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 64 Kbps.
The ADSL up/down shift noise margins define the
threshold that triggers rate adaptation. For example:
The target SNR is 6, and the up/down shift noise
margins are 9/3.
If the signal becomes better and the SNR is higher
than 9, rate adaptation is triggered and the line rate
becomes higher
If the signal becomes bad and the SNR is lower than 3,
rate adaptation is triggered and the line rate becomes
lower.
After you create an ADSL profile, you can assign it to
any of the ADSL ports on any of the ADSL IES-1248-
51V in the IES-1248-51V.
H/H
adsl profile delete < profile >
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 in the IES-1248-51V. 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. H/H
