Port Adsl Uscarrier Command - ZyXEL Communications MSC1024G Series User Manual

This command assigns a specific profile to an ADSL port(s) and sets the port's ADSL mode
(or standard). The profile defines the 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 to which you assign the profile.
When the mode is set to
negotiated ADSL mode regardless of the rates configured in the profile. For
example, if the profile is set to use a rate of 18000 Kbps, that speed is only
supported if the negotiated ADSL mode is ADSL 2+. Any other ADSL mode
will limit the rate to what is supported by the specific ADSL standard.
The following example sets ADSL port 5 on the line card in slot 7 to use the gold profile and
mode.

31.4.17 port adsl uscarrier Command

Syntax:
port adsl uscarrier <slot-port> <m0> <m1>
where
,
<m0> <m1>
This command disables upstream carrier tones from 0 to 63 on the specified ADSL port(s).
Use this command to have the system not use an ADSL line's tones that are known to have a
high noise level.
The following example disables upstream carrier tone 8 for ADSL port 5 on the line card in
slot 7.
ras> port adsl uscarrier 7-5 00000080 0
This example disables upstream carrier tones 8 and 9 for ADSL port 5 on the line card in slot
7.
ras> port adsl uscarrier 7-5 00000180 0

= The upstream subcarriers to be disabled. Each <mx> can use up to 8
hexadecimal digits (0~ffffffff). Each <mx> represents 32 carrier tones (each
hexadecimal digit represents 4 tones).
tones 0~31
m0:
m1: tones 32~63
The hexadecimal digit is converted to binary and a '1' disables the
corresponding tone. Disabling a carrier tone turns it off so the system does
not send data on it.
