Rate Table
Standard
– Selects the standard rate table for use when
operating with standard endpoints.
Nx128
– Selects the Nx128 rate table for use when operating
with nonstandard endpoints (most are multiples of 128).
Behavior
The training behavior (Default = Auto Baud):
Fixed
– The line card will train only at the rate set in the Fixed
Speed field (Standard default = 784 kbps; Nx128 default =
768 kbps).
Auto Baud
– The line card will train up to the highest
operational rate less than or equal to the rate set in Auto Baud
Max Speed.
Fixed Speed
The DSL line rate if Behavior is set to Fixed:
Available Standard rates are
144, 272, 400, 528, 784, 1168,
1552,
or
2320 kbps
(Default = 784 kbps).
Available Nx128 rates are
144, 256, 384, 512, 768, 1024,
or
1536 kbps
(Default = 784 kbps).
Auto Baud Max
Speed
The maximum DSL line rate the card can train to if Behavior is
set to Auto Baud:
Available Standard rates are
144, 272, 400, 528, 784, 1168,
1552,
or
2320 kbps
(Default = 2320 kbps).
Available Nx128 rates are
144, 256, 384, 512, 768, 1024,
or
1536 kbps
(Default = 1536 kbps).
Auto Baud Target
Margin
A range of
0
to
15
dB. The upper limit for margin used by the
Autobaud algorithm during training. After training, if the margin
is greater than the target margin, the card will attempt to retrain
at a higher rate, if the DSL line conditions permit. This field only
appears if Autobaud is selected (Default = 9 dB).
Auto Baud
Minimum Margin
A range of
0
to
15
dB. The lower limit for margin used by the
Autobaud algorithm during training. After training, if the margin
is less than the minimum margin, the card will attempt to retrain
at a lower rate. This field only appears if Autobaud is selected
(Default = 5 dB).
Link Down Count
A number from
0
to
900
(Default = 0 (disable).
If the number of DSL Link Down events exceeds the selected
number within a 15-minute period, an SNMP trap is sent. If
Link Down Count is set to Disable, no Link Down trap is ever
sent.
Link Up/Down Trap
Enable or Disable to enable/disable link up/down traps
(Default = Enable).
Enable
– Enables link up/down traps.
Disable
– Disables link up/down traps.
