ADSL Commands
This chapter describes some of the ADSL commands that allow you to configure
and monitor the ADSL ports.
64.1 ADSL Command Input Values
The following table describes the values required in ADSL commands. Other
values are discussed with the corresponding commands.
Table 183 ADSL Command Input Values
LABEL DESCRIPTION
down-
downshift-
margin
The downstream down shift noise margin (0~31 dB).
down-max-
margin
The maximum acceptable ADSL downstream signal/noise margin
(0~31db).
down-max-rate
The maximum ADSL downstream transmission rate (32~25000
Kbps).
down-min-
margin
The minimum acceptable ADSL downstream signal/noise margin
(0~31db).
down-min-rate
The minimum ADSL downstream transmission rate (32~25000 Kbps).
down-target-
margin
The target ADSL downstream signal/noise margin (0~31db).
fast|interlea
ve[=< up-
delay >,< down-
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.
max-nominal-
psd
Maximum nominal transmit PSD (Power Spectral Density) measured
in 0.1dBm/Hz.
mx
The downstream carrier tones to be masked (disabled). Each <mx>
can use up to 8 hexadecimal digits (00000000~ffffffff). Each <mx>
represents 32 carrier tones (each hexadecimal digit represents 4
tones).
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.
