3.2.2.4 G.lite

G.lite is ADSL technology in compliance with the standards of ITU-T
Recommendation G.992.2. The AIM24000 meets the ITU-T Recommendation
G992.2 minimum requirements of 512 kbps upstream and 5,136 kbps
downstream speeds in G.lite mode. An AIM24000 port that is operating in G.lite
mode and utilizing a single line for both phone and data, requires an in-line
splitter at the local end, and a microfilter at the remote end, of the ADSL
connection.
3.2.3 Port Mode
Default: Adaptive
3.2.3.1 Adaptive
An AIM24000 port set to port mode adaptive will automatically train up to the
best possible speed supported by the AIM24000, the ADSL modem at the
remote end, and the copper cable pair connecting the two.

3.2.3.2 Fixed

An AIM24000 port set to port mode fixed will maintain consistant upstream and
downstream bandwidths as specified by the user.

3.2.3.3 Fixed Adaptive

An AIM24000 port set to port mode fixed adaptive will automatically train up to
the best possible speed supported by the AIM24000, the ADSL modem at the
remote end, and the copper cable pair connecting the two, within the confines
of user-specified maximum upstream and downstream bandwidths.
3.2.3.4 Off
An AIM24000 port set to port mode off has been administratively turned off.

3.2.4 Bandwidth and Distance

The default bandwidth for AIM24000 ADSL connections is Adaptive as defined in
section 3.2.3.1. The eventual outcome could be any combination of existing possible
upstream and downstream bandwidths, and may or may not be reflected in the
following tables. For AIM24000 ports configured at Fixed or Fixed Adaptive port
modes, bandwidth parameters must be manually specified.
The distance capabilities listed in the following tables assume the use of 26 American
Wire Gauge (AWG) cable; connections made with cable of a greater gauge (e.g., 24
AWG) will link up at greater distances. The AIM24000 may not link up if the cable is
in poor condition or if the cable distance is greater than a particular bandwidth will
support. Remote ADSL modems determine bandwidth through their communication
with the AIM24000.
N OTE The following tables show maximum possible distances for various sample combinations of upstream and
downstream bandwidths over a typical ADSL line. Data given is meant solely as a guide in determining achievable
distances at various bandwidth settings; these tables are NOT COMPREHENSIVE. The many possible combinations
of upstream and downstream bandwidths, along with attainable corresponding distances for each combination,
are far more numerous than that which is feasible to list here.

AIM24000 Installation 210-0000056 rev 01
3.2.4.1.1 G.DMT.BIS (ADSL2)
An AIM24000 port in ADSL2 mode is capable of reaching downstream
speeds of up to 11,937 kbps under optimal conditions.
