• Note that this parameter only applies to interleaved channels. Refer to
ITU-T G.993.2 for a full description of the methods used to calculate
the minimum level of impulse noise protection.
Example
lre channel
This command sets the channel mode to fast or interleaved. Use the no
form to restore the default status.
Syntax
lre channel mode
no lre channel
mode – Channel mode (Options: fast, interleave)
Default Setting
interleaved
Command Mode
Interface Configuration (VDSL Port)
Command Usage
• Interleaving protects data against bursts of errors by using the
Reed-Solomon error correction algorithm to spread the errors over a
number of code words. A greater degree of interleaving provides more
protection against noise pulses, but increases transmission delay and
reduces the effective bandwidth.
• For applications that cannot tolerate latency (for example, voice), use
the fast mode to disable the interleaving burst error correction
method.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#lr min-protection down 5
Console(config-if)#
Console(config)#interface ethernet 1/1
Console(config-if)#lre channel interleave
