Target SNR Margin
ATU-C/ATU-R
The Signal-to-Noise Ratio (SNR) margin relative to a Bit
Error Ratio of 10
-7
required for a successful activation of
the port for the ATU-C and ATU-R. The maximum SNR is
always 16 dB, while the minimum is always 0 dB. The SNR
margin for rate downshift is 3 dB below the Target SNR
Margin. When the SNR margin falls below this level, the
device will attempt to decrease its transmit rate. The SNR
margin for rate upshift is 2 dB above the Target SNR
Margin. When the noise margin rises above this level, the
device will attempt to increase its transmit rate. Rate shifts
occur as soon as the margin threshold is exceeded.
3 dB – 14 dB
in 1 dB increments (Default = 4 dB).
Alarm Profile
The name of the alarm configuration profile (up to
32 alphanumeric characters). Press Ctrl-v to display a list of
all available alarm profiles configured on the card. Either
select an existing profile to change, or select New Profile to
create a new alarm profile. An asterisk (*) indicates the
profile is referenced by other ports.
Each profile name must be unique. Up to 30 profiles can be
configured. Profiles can be used by multiple ports and can
be changed at any time. All ports share a single default
alarm profile as part of the factory defaults. Errored
Seconds Trap Threshold, Severely Errored Seconds Trap
Threshold, Unavailable Seconds Trap Threshold, Loss of
Power Trap Threshold, and Increasing Rate Alarm
Threshold are part of the alarm configuration profile.
Errored Seconds Trap

If the number of DSL Errored Second events equals or
exceeds the selected number within a 15-minute period, an
SNMP trap is sent. If set to Disable or 0, no Errored Second
trap is ever sent. If set to 1, a trap is sent after each Errored
Seconds event.
Severely Errored
Seconds Trap
Threshold
ATU-C/ATU-R
A number from
0
to
900,
or a
D
for Disable
(Default = 15).
If the number of DSL Severely Errored Second events
equals or exceeds the selected number within a 15-minute
period, an SNMP trap is sent. If set to Disable or 0, no
Severely Errored Seconds trap is ever sent. If set to 1, a
trap is sent after each Severely Errored Seconds event.
Unavailable Seconds
Trap Threshold
ATU-C/ATU-R
A number from
0
to
900,
or a
D
for Disable
(Default = Disable).
If the number of DSL Unavailable Second events equals or
exceeds the selected number within a 15-minute period, an
SNMP trap is sent. If set to Disable or 0, no Unavailable
