ADSL Port Setup
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.
7.1 ADSL Standards Overview
These are the ADSL standards and rates that the MSAP2000 AAM supports at the
time of writing.
Table 14 Maximum Transfer Rates of the ADSL Ports
STANDARD MAXIMUM DOWNSTREAM MAXIMUM UPSTREAM
G.dmt 8160 Kbps 1024 Kbps
ANSI T1.413 issue 2 8160 Kbps 1024 Kbps
G.lite 1536 Kbps 512 Kbps
ADSL2 12000 Kbps 1200 Kbps
ADSL2+ 24000 Kbps 1200 Kbps
7.2 Downstream and Upstream
Downstream refers to traffic going out from the MSAP2000 AAM to the
subscriber's ADSL modem or router. Upstream refers to traffic coming into the
MSAP2000 AAM from the subscriber's ADSL modem or router.
7.3 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.
