4.6.5.4 <MASTER ON/OFF/AUTO N> command
The <MASTER ON/OFF N> activates/deactivates the «MASTER» mode on the interface with
the number N.
The <MASTER ON> activates the MASTER mode. The <MASTER OFF> command activates
the SLAVE mode.
Note:
In the data transmission systems one device should be configured as a Master
device,
while the other
– as a Slave device.
The parameter N is used to select the interface DSL1/DSL2 (the
ON/OFF is not used).
The <MASTER AUTO> selects automatically the Master/Slave mode
For example:
RR_CM>MASTER AUTO
4.6.5.5 <BASERATE K/AUTO [N=1..4]> command
The <BASERATE
K [N=1..4]>
command sets the transmission rate K over the line xDSL
interface, where N is the number of the interface.
For PAM16 the available rates (BASERATE) lie in the range from 3 to 60, and for PAM32
– from
12 to 89.

Warning!
Use codes with the lowest number of levels (PAM16) for low rates.
On the Slave device, the <BASERATE AUTO> command adapts the rate of the Slave device to
the rate of the Master device. In this case, PAM and Annex are automatically detected
(opposite Annex in the <CONFIG> configuration AB appears, opposite PAM
– Auto).
The command does not change the Annex and PAM modes in the configuration. In the
Slave mode, the <BASERATE AUTO> command automatically detects all
configurations.
On the Master device, the <BASERATE AUTO> command sets the mode of adaptation to the
line quality. In this case the <BASERATE AUTO> mode should be also activated on the
Slave device.
For modems with one xDSL channel, the command is entered without typing the number of the
xDSL channel.
