Command Usage
This command is used to set the bit rate in each direction by the minimum
bit rate and maximum bit rate parameters. These parameters are used dur-
ing line training. Setting these two parameters to the same value will ensure
that the line either has the specified speed, or else, be down and an alarm
issued (adslAtucInitFailureTrap), if the alarm is enabled in the Alarm Con-
figuration. The Interleaved delay improves the error correction capabilities
of the ADSL connection (and therefore less retransmissions). The Inter-
leaved delay determines the improvement of the error correction: long de-
lay improves more than short delay. The L2 power mode is a low power
mode, which is entered automatically, based upon traffic load to save
power. This power mode is an ADSL2 feature. It is possible to enable it for
all line types, but it will only have effect on lines running ADSL2.
Example
ecn330(config)# dslport 1.0.1 channel 0 downstream
min-bit-rate 32 max-bit-rate 512 interleave-delay 20
ecn330(config)# dslport 1.0.1 channel 0 downstream

Arguments:
•
<dslport>
- The DSL-port to configure. The parameter
<a.b.c>
refers to the ECN port (a), the ESN108 port (
b
) and the IP DSLAM
line (
c
).
