9.4.5 SHDSL Profile Set Command
Syntax:
lcman port profile set shdsl <profile> <max rate> <min rate> anxa|anxb
[2wire|4wire|mpair4 lp_off|lp_on_curr[=<value>]|lp_on_wc[=<value>]]
where
ras> lcman port profile show shdsl DEFVAL
shdsl profile: DEFVAL mode: anxb
max rate : 2304 Kbps
min rate : 192 Kbps
wire interface: 2wire
line probe : disabled
ras>
<profile>
= The descriptive name for the profile.
<max rate>
= The maximum SHDSL upstream transmission rate.
<min rate>
= The minimum SHDSL downstream transmission rate.
anxa|anxab
= The region setting, annexb is the default.
annexa
= DSL over POTS.
annexb
= DSL over ISDN.
2wire|4wire|
mpair4
= The wire pair number.
2wire
= a normal connection using a single SHDSL port’s two wires,
this is the default.
4wire
= a 4-wire n-wire group (two SHDSL ports grouped together).
mpair4
= an 8-wire n-wire group (four SHDSL ports grouped
together).
lp_off
= Disable line probe.
The SHDSL line card and subscriber modem use line probes to
determine the best possible transmission rate. This is used in rate
adaptation. This is the default line probe mode.
If you disable line probe, the system skips the rate adaptation phase to
shorten connection set up time.
lp_on_cur
= Enable line probe with current target Signal to Noise Ratio margin.
lp_on_wc
= Enable line probe with worst case target Signal to Noise Ratio margin.
<curr-
margin>
= The current condition target Signal to Noise Ratio margin, -10 ~ 21 in
dB.
<worst-
margin>
= The worst case Signal to Noise Ratio margin, -10 ~ 21 in dB.
