Model 3088 Series User Manual
• DSL Error Monitor Interval Count: The number of errored intervals allowed before restarting the DSL
link.
• DSL Error Monitor Total Intervals: The number of intervals to inspect before disabling the error moni-
tor.
• DSL Error Monitor Startup Delay: The length in seconds to wait after the DSL link is established before
starting the error monitor.
• Test Modes: Loopbacks (LAL or RDL) and PRBS (pseudo-random binary sequence) BER tests (511 or
511 with errors)
• Line Probe: Enable or disable Line Probe for rate adaptive applications.
The following status information is available through the command line interface:
• LEDs: Which software controlled LEDs are currently on.
• FPSW Settings: What the front panel switches are set to (if the unit is populated with them).
• Configuration Mode: Whether the 3088 is configured by DIP switches or software.
• DSL Link State: In Progress, Success, Deactivated, or Idle.
• DSL Sync State: Out of Sync, Acquiring Sync, In Sync, or Losing Sync.
Note DSL Link State vs. DSL Sync State—The DSL link state describes whether
the DSL is training (in progress), linked (success), deactivated (we don't have
an option to deactivate the modem, so the user should not see this), or idle.
The DSL sync state describes whether no sync words have been found (out
of sync), there are no sync word errors (in sync), or whether we are transi-
tioning from out of sync to in sync (acquiring sync) or vice versa (losing
sync). Typically, when the link is training, the sync state goes from out of
sync to acquiring sync to in sync.
• DSL Actual Rate: The actual rate at which the DSL link is running (minus DSL overhead).
• DSL Line Condition: Good or Poor.
• Noise Margin Ratio: the maximum tolerable increase in external noise power that still allows for BER of
7
less than 1x 10– .
• DSL Error Counters: The following error counters are available:
- CRC
- LOSW (Loss of Sync Word)
- TX FIFO Full
- TX FIFO Empty
- TX FIFO Slip
- TX Stuff
- RX FIFO Full
