G.SHDSL Line Provision window 129
Models 2616RC, 3096RC & 3196RC Admin Reference Guide 9 • G.SHDSL (Model 3096RC)
• Severely Errored Seconds (SES) (historySESgshDSL)—Indicates the total cumulative number of seconds
in which there were one or more CRC errors on this port during the 15-minute interval. The T-DAC will
not increment the SES count for this port when the T-DAC is incrementing the Unavailable Seconds
count.
• Unavailable Seconds (UAS) (historyUASgshDSL)—Indicates the total cumulative number of seconds that
the G.SHDSL port was unavailable during the 15-minute interval. Total cumulative time in seconds that
the link state for this port has been down(0). The UAS counter is incremented under the following criteria.
- The port state must be datamode(1) and the port link state must have been up(1) for 5 seconds or more.
- When the port state changes to down(0) the 3096RC will begin counting UAS. The 3096RC will not
increment ES or SES during the UAS count.

G.SHDSL Line Provision window
The G.SHDSL Line Provision window provides an automated tool for calculating the optimum payload rate
the G.SHDSL link connected to this port. The line provision tool determines the optimal payload rate by
resolving line length and line quality. The CO and CP exchange sequences of line probe messages. The CO
interprets the messages and calculates a worst-case payload value. The worst-case value determines the highest
payload rate the CO and CP can achieve without errors.
Note
Line probe must be enabled on the CP.
Note
This tool will cause the DSL line to be retrained.

Rate button, click the Refresh Current Page button often to update the current operating status of the tool,
and to display the calculated rate when the tool has completed its calculations.
