30.5.1 profile adsl set Command
Syntax:
profile adsl set < profile > <us-max-rate> <ds-max-rate>
[fast|delay <us-delay> <ds-delay>]
[minrate <us-min-rate> <ds-min-rate>]
[usmgn <us-max-mgn> <us-min-mgn> <us-tgt-mgn>]
[dsmgn <ds-max-mgn> <ds-min-mgn> <ds-tgt-mgn>]
[usra fixed|startup|runtime <us-us-mgn> <us-ds-mgn>]
[dsra fixed|startup|runtime <ds-us-mgn> <ds-ds-mgn>]
where
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
<profile>
=
The descriptive name for the profile.
< us-max-rate >
=
The maximum ADSL upstream transmission rate, 64~4096 in Kbps.
The upstream rate must be less than or equal to the downstream rate.
< ds-max-rate >
= The maximum ADSL downstream transmission rate, 64~32000 in Kbps.
[fast|delay < us-
delay > < ds-delay >]
= The latency mode. With interleave, you must also define the upstream
and downstream delay (1-255 ms). It is recommended that you
configure the same delay for both upstream and downstream.
[minrate < us-min-
rate > < ds-min-rate >]
=
The minimum ADSL upstream transmission rate (32~4096 Kbps) and
the minimum ADSL downstream transmission rate (32~32000 Kbps).
[usmgn < us-max-mgn >
< us-min-mgn > < us-
tgt-mgn >]
= The maximum, minimum and target acceptable ADSL upstream signal
to noise margins (0~310 in 0.1 dB measurements).
[dsmgn < ds-max-mgn >
< ds-min-mgn > < ds-
tgt-mgn >]
=
The maximum, minimum and target acceptable ADSL downstream
signal to noise margins (0~310 in 0.1 dB measurements).
usra
= The upstream rate adaptation setting.
fixed
: no rate adaptation
startup
: rate adaptation at initialization
runtime
: rate adaptation any time
dsra
= The downstream rate adaptation setting.
< us-us-mgn >
=
The upstream up shift noise margin (0~310 in 0.1 dB).
< us-ds-mgn >
= The upstream down shift noise margin (0~310 in 0.1 dB).
< ds-us-mgn >
= The downstream up shift noise margin (0~310 in 0.1 dB).
< ds-ds-mgn >
=
The downstream down shift noise margin (0~310 in 0.1 dB).
