Chapter 8 Adsl Port Setup; Adsl Standards Overview; Downstream And Upstream; Profiles - ZyXEL Communications AAM1212 User Manual

This chapter explains how to configure settings for profiles and individual ADSL ports. It also
covers how to configure virtual channels and virtual channel profiles.

8.1 ADSL Standards Overview

These are the ADSL standards and rates that the AAM supports at the time of writing.

Table 14 Maximum Transfer Rates of the ADSL Ports

STANDARD
G.dmt
ANSI T1.413 issue 2
G.lite
ADSL2
ADSL2+

8.2 Downstream and Upstream

Downstream refers to traffic going out from the AAM to the subscriber's ADSL modem or
router. Upstream refers to traffic coming into the AAM from the subscriber's ADSL modem or
router.

8.3 Profiles

A profile is a table that contains a list of pre-configured ADSL settings. Each ADSL port has
one (and only one) profile assigned to it at any given time. The profile defines the latency
mode and upstream/downstream latency delay, maximum and minimum upstream/
downstream rates, the target upstream/downstream signal noise margins, and the maximum
and minimum upstream/downstream acceptable noise margins of all the ADSL ports that have
this profile. You can configure multiple profiles, including profiles for troubleshooting.
Profiles allow you to configure ADSL ports efficiently. You can configure all of the ADSL
ports with the same profile, thus removing the need to configure the ADSL ports one-by-one.
You can also change an individual ADSL port by assigning it a different profile.
