Stuc Alarm Profile Select an alarm profile to define the thresholds that trigger an alarm
on the port when exceeded. This alarm profile is for the STU-C
(SHDSL Termination Unit - Central) end point. Use the Alarm Profile
screen to configure alarm profiles. (See
Stur Alarm Profile Select an alarm profile to define the thresholds that trigger an alarm
on the port when exceeded. This alarm profile is for the STU-R
(SHDSL Termination Unit - Remote) end point. Use the Alarm Profile
screen to configure alarm profiles. (See
IGMP Filter Profile The IGMP filter profile defines which multicast groups a port can join.
Select a profile of IGMP filter settings to assign to this port. Use the
IGMP Filter Profile screen to configure IGMP filter profiles (see
SHDSL feature
Power Backoff
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
DSL profile). You can normally just leave the default setting
(NORMAL_EPL). You only need to use this if the STU-R does not
support EPL or you need to configure the port to use a specific power
backoff setting.
Select NORMAL_EPL to use power backoff with EPL (Estimated
Power Loss). Each end calculates an EPL and uses it in determining a
power backoff value for the other end to use.
Select FORCED_EPL to use forced power backoff with EPL. The STU-
C 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.
Select FORCED_NO_EPL to use 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).
Set the power backoff value (0~31 in dBm).
When using NORMAL_EPL or FORCED_EPL, this sets the maximum
power backoff value.
When using FORCED_NO_EPL, this sets the power backoff value.
PMMS
Specify how the target noise margin value is acquired.
Select normal to have each end of the connection determine the
target noise margin to be used by the other end.
Select forced to set the upstream and downstream parameters
according to the target noise margin value set in the DSL profile.
Mode
Select the port’s operational mode.
Select efm to use Ethernet frames inside SHDSL framing. This option
has less overhead and better data transmission rates.
Select atm to use ATM cells inside SHDSL framing. Select this when
your CPE device only supports this mode.
