Model 3086FR ATM IAD User Guide 5 • Configuring the DSL and serial ports
Line Probe
Line probe is a tool used to determine maximum achievable rate when initially connecting 3086 to a copper
line of unknown quality. Set this feature to “Enable” on both 3086s at each end of the link.
Note
Once line probe measurements have been completed set this feature to
“Disabled”
The bottom four fields in the G.SHDSL Attributes page correspond to error monitors. Error monitor will
watch the DSL line parameters and determine whether or not the current DSL link is capable of passing error
free data. The error monitor will accumulate DSL line statistics (CRC count, FIFO errors, LOSW count,
etc..) and make a determination on whether or not to drop DSL link and retrain based on the thresholds setup
by the user
• Error Monitor Max Interval Errors: Number of allowable errors per interval. Default = 3
• Error Monitor Interval Time (sec): Length in seconds of the current interval. Default = 1
• Error Monitor Interval Count: Number of intervals in error before the DSL link is restarted. Default = 3
• Error Monitor Start Up Delay: Amount of time to wait, after the link is up, before monitoring the DSL
link. Default = 5
Once you have entered your selections or changes, click on the “Configure” button at the bottom of the screen.
Additional go to the G.SHDSL > Action link on the left side of the screen, and hit “action” to start the DSL
interface with the new settings.
Refer to section “Configuring the serial port” on page 50.
Configuring the DSL interface using the CLI
Access the command line interface via local terminal or Telnet. To configure the DSL interface enter the fol-
lowing commands.
DSL Data Rate
Set the DSL rate by entering bandwidth in number of timeslots (each timeslot (TS) equals 64kbps) for exam-
ple to select a DSL bandwidth of 512kbps enter 8 timeslots as follows:
--> gshdsl set dslrateTS 8
DSL timeslot options go from 3 = 192kbps to 36= 4.6Mbps
Data Link Interface
The datalink interface for the 3086FR is ATM. Enter the command as follows:
--> gshdsl set interface atm
Annex Type
Annex type refers to spectral compatibility between DSL and T1 or E1 lines traveling in the same bundle. For
North America and other areas where T1 lines are used, select Annex A, for areas where E1 lines are used select
Annex B.
