64.3 ADSL Profile Commands

Table 185 ADSL Profile Commands

COMMAND DESCRIPTION P

adsl profile show [profile] Displays the specified ADSL profile or all ADSL profiles

if you do not specify one.

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.
