ADSL Port Commands
A block is a set of consecutive bits associated with the path; each bit belongs to one and only one block.
Consecutive bits may not be contiguous in time.
Table 11-1 Line Performance Counters
LABEL DESCRIPTION
nfebe
The number of far end block errors.
ncrc
Near end cyclic redundancy checks.
nfecc
The number of end forward error correction count.
nfec
The number of end forward error count.
nblks
The number of blocks transmitted.
nsec
The number of seconds the connection has been up.
n-es
The number of errored seconds. This is how many seconds contained at least one errored block or at
least one defect.
n-ses
The number of severely errored seconds. This is how many seconds contained 30% or more errored
blocks or at least one defect. This is a subset of n-es.
n-uas
The number of unavailable seconds.

Set ADSL Profile Command
Syntax:
lcman port profile set adsl <profile> <fast|interleave[=<up delay>,<down
delay>]> <up max rate> <down max rate>[<up target margin> <up min margin> <up
max margin> <up min rate> <down target margin> <down min margin> <down max
margin> <down min rate>]
where
<profile> =
The descriptive name for the profile.
<fast|interleave[=
<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.
<up max rate>
=
The maximum ADSL upstream transmission rate (32-3000 Kbps).
<down max rate>
=
The maximum ADSL downstream transmission rate (32-25000 Kbps).
<up target margin> =
The target ADSL upstream signal/noise margin (0-31db).
<up min margin>
=
The minimum acceptable ADSL upstream signal/noise margin (0-31db).
<up max margin>
=
The maximum acceptable ADSL upstream signal/noise margin (0-31db).
<up min rate>
The minimum ADSL upstream transmission rate (32-3000 Kbps).
<down target
margin>
=
The target ADSL downstream signal/noise margin (0-31db).
<down min margin>
=
The minimum acceptable ADSL downstream signal/noise margin (0-
31db).
