Configuring ADSL Line Profiles
C
ONFIGURING
ADSL line profiles contain a preconfigured set of parameters, including the transmit rate, rate
adaptation mode, target margin, and interleave delay. ADSL port configuration requires you to
apply an ADSL line profile to the line, therefore you must configure the desired ADSL line
profile before configuring the ADSL port. A default profile exists with an index of 1. You
cannot delete the default profile.
You configure ADSL line profiles from the ::line=> prompt. From the ::root=> prompt,
type the following command then press
configuration adsl profile line
Adding ADSL Line Profiles
From the ::line=> prompt, type the new command in one of the following formats then press
ENTER
to create a new ADSL line profile. The profile is automatically assigned the next
available index number in the ADSL line profile table.
new fixed <margin> <upstream delay> <downstream delay> <maximum
upstream rate> <maximum downstream rate>
new adaptive <margin> <upstream delay> <downstream delay>
<maximum upstream rate> <maximum downstream rate> <minimum
upstream rate> <minimum downstream rate>
Parameters
(fixed|adaptive)
The form of transmit rate adaptation. Options:
fixed—The loop must be able to come up at the specified maximum upstream rate, or it
does not come up at all.
adaptive—The loop will come up at the highest achievable rate that is greater than the
specified minimum upstream rate but less than the maximum upstream rate. This
adaptation occurs at startup only.
<margin>
The upstream target signal-to-noise margin in decibels that the modem must achieve with
-7
a BER of 10
6. A lower margin may result in a higher data rate, but increases noise on the line.
