The following example displays the results.
This example disables downstream carrier tones 70 and 71 for ADSL port 5.
55.1.15 ADSL Downstream Carrier1 Command
Syntax:
ras> adsl dscarrier1 <port number> [<m0> <m1> <m2> <m3> <m4> <m5> <m6> <m7>]
where
The hexadecimal digit is converted to binary and a '1' masks (disables) the corresponding tone.
Disabling a carrier tone turns it off so the system does not send data on it.
This command displays or sets masks for downstream carrier tones from 256 to 511 on the
specified ADSL2+ 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 downstream carrier tone 307 for ADSL2+ port 5.
