− priority-to-power – The output power will be the lowest
possible and the bandwidth will be between minimum peak cell
rate and maximum peak cell rate.
− priority-to-rate – The output power is optimized to
reach maximum peak cell rate with the lowest possible output
power. PEM will overrule the default setting (fixed) of the IP
DSLAM to this priority-to-rate mode.

Command Usage
The command is used to set properties of the ADSL transmission. All the
target and time arguments are related to Rate Adaption Mode. The Rate
Adaptation Mode argument is only related to lines that operate with ADSL2
or ADSL2+. On lines operating with ADSL1 this parameter will not have any
influence. Note that the values for this argument are different from the val-
ues available from PEM (where the values are enabled/disabled). The pos-
sible values from the CLI correspond to RFC2662. The corresponding val-
ues in ITU-T G.997.1 are Manual (fixed), At_Init (at-startup) and Dynamic
(at-runtime). For more information about the rate adaptation please refer to
ITU-T 997.1 or RFC2662.
