Line Length
The estimated distance from the local exchange to
determine the speeds that can be supported. This value is
usually specified by the carrier. This option is available only
if Spectrum Management is set to Enable and Region is set
to Annex B on the Spectrum Management screen (menu
selection A-A-G). Select from the following
(Default = Short):
Short – Can support speeds up to 2056 kbps (in 64 kbps
increments).
Medium – Can support speeds up to 1480 kbps (in 64 kbps
increments).
Long – Can support speeds up to 840 kbps (in 64 kbps
increments).
Allowed Speeds
Displays the range of allowed speeds based on spectrum
management requirements. If Spectrum Management is
set to Disable on the Spectrum Management screen (menu
selection A-A-G), then only the applicable speeds for the
Annex selected and PSD mask used are displayed.
Speeds are selectable in 64 kbps increments.
Behavior
The training behavior (Default = Adaptive):
Adaptive – The line card will train up to the highest
operational rate less than or equal to the maximum fixed or
adaptive speed.
Fixed – The line card will train only at the rate set in the
Fixed Rate field.
Fixed Rate Speed
The DSL line rate the card trains to if Behavior is set to
Fixed. Choose from rates listed in the Allowed Speeds
field. Speeds are selectable in 64 kbps increments.
Maximum Adaptive
Speed
The maximum DSL line rate the card can train to if
Behavior is set to Adaptive. Choose from rates listed in the
Allowed Speeds field.
Minimum Adaptive
Speed
The minimum DSL line rate the card can train to if
Behavior is set to Adaptive. Choose from rates listed in
the Allowed Speeds field.
Startup Margin
The noise margin relative to a Bit Error Ratio of 10
-7
required for a successful activation of the port:
2 – 15 dB in 1 dB increments (Default = 2 dB).
Error Seconds
A number from 0 to 900, or a D for Disable
(Default = 120).
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.
