Profile Adsl Map Command - ZyXEL Communications MSC1000G User Manual

The profile is a list of ADSL line configuration settings. After you create an ADSL profile,
you can assign it to any of the ADSL ports on any of the ADSL line cards.
Note that the default value will be used for any of the above fields that are omitted.
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 then 3, rate adaptation is triggered and the line
rate becomes lower.
The following example creates a premium profile (named gold) for providing subscribers with
very high connection speeds and no interleave delay. It uses the following settings.
• The maximum upstream rate is set to 2048 Kbps.
• The maximum downstream rate is set to 16000 Kbps.
• No interleave delay.
• The minimum upstream is set to 1024 Kbps.
• The minimum downstream is set to 3072 Kbps.
• The maximum, minimum and target acceptable ADSL upstream signal to noise margins
are set to 12, 0 and 6 dB respectively.
• The maximum, minimum and target acceptable ADSL downstream signal to noise
margins are also set to 12, 0 and 6 dB respectively.
• Upstream and downstream rate adaptation are both set to operate whenever the link is up.
• The upstream up/down shift noise margins are set to 9/3 dB.
• The downstream up/down shift noise margins are set to 9/3 dB.

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.
