This command sets the specified SHDSL port(s) or end point(s) to use an alarm profile.
The following example sets SHDSL port 8 on the line card in slot 6 to use the SESalarm alarm
profile at both the STU-C and the STU-R.

This command sets the power backoff feature setting on the specified SHDSL port(s). Power
backoff calculates how much power is needed for the connection. This allows the STU-C and
STU-R to use only enough power for the port's maximum transmission rate (configured in the
SHDSL profile). You can normally just leave the default setting (
need to use this command if the STU-R does not support EPL or you need to configure the
port to use a specific power backoff setting.

= span : Sets the alarm profile for the whole span. This is the entire
connection including any SHDSL regenerators that might be located
between the STU-C (SHDSL Termination Unit - Central) and STU-R
(SHDSL Termination Unit - Remote) end points. An SHDSL
regenerator amplifies the SHDSL signal in order to increase the
connection distance.
stuc : Sets the alarm profile at STU-C (SHDSL Termination Unit -
Central) end point

stur
Remote) end point

Each end calculates an EPL and uses it in determining a power
backoff value for the other end to use.

forced_epl:
calculates an EPL and uses it in determining the power backoff
values for both ends. This can be used when the STU-R device
does not support EPL.
forced_no_epl : Forced power backoff without EPL. The STU-
C uses the value you specify in determining the power backoff
values for both ends. This can be used when you have prior
knowledge about the physical line (loop).
