Chapter 29 port Commands
Management Switch Card User’s Guide
820
This example sets SHDSL port 7 on the line card in slot 6 to use 13 dB of power backoff for both
downstream and upstream.
29.30.4 port shdsl pmms Command
Syntax:
port shdsl pmms <slot-port> <mode>
where
This command sets the PMMS (Power Measurement Modulation Session) mode of the specified
SHDSL port(s).
The following example sets SHDSL port 8 on the line card in slot 6 to use the negotiated target
noise margin mode.
29.30.5 port shdsl set Command
Syntax:
port shdsl set <slot-port> <profile>
where
This
command assigns a specific profile to an SHDSL port(s). The profile defines the maximum and
minimum transmission rates, the regional setting, the number of wire pairs to be used, whether
line-probing is enabled or disabled and the target and worst case noise margins.
The following example sets SHDSL port 8 on the line card in slot 6 to use the gold profile.
ras> port shdsl pbo 6-7 forced_no_epl 13
<mode>
=
The PMMS (Power Measurement Modulation Session) mode specifies how the target
noise margin value is acquired.
normal: Negotiated target noise margin mode. Each end of the connection
determines the target noise margin to be used by the other end for the evaluation of the
PMMS results.
forced: Forced target noise margin mode. The upstream and downstream
parameters are set according to the target noise margin value set in the SHDSL profile.
ras> port shdsl pmms 6-8 normal
<profile> = The SHDSL profile that will define the settings of this port.
ras> port shdsl set 6-8 gold
