B • Specifications
Terminal (Green)
The Terminal LED glows solid under the following circumstances:
•
3088A/CA with V.35 interface and 3088A/A with RS-232 interface:
if the serial interface has asserted
DTR
•
3088A/D with the X.21 interface
-
Configured as DCE
: Indicates that the “Control” signals have been asserted.
-
Configured as DTE
: Indicates that the “Indication” signals have been asserted
TM/ER (Yellow)
The Test Mode/Error (TM/ER) LED is used to indicate that a test mode is in progress or an error has been
detected. It blinks once every second while a test mode is starting. It glows solid while a test mode is in
progress. It blinks once if an error is detected either during a test mode, or in normal DSL operation.
LOS (Red) [Model /K]
The LOS LED blinks once per second to indicate either framing errors or clock slips. Clock slips are often
caused by a mis-configured clock mode.
Link (Green)
The Link LED shows that there is an active physical connection to the Console.
Activity (Green)
The Activity LED shows that there is data being transferred through the Console connection. During a soft-
ware upgrade procedure, if the Activity LED is on for an unusually long time, there is a problem with the
upgrade, and the device should be restarted. The TFTP server should be checked (normal upgrades take about
10 seconds on a 100mbit link).
Configuration
Configuration is done with either externally accessible DIP switches, CLI or through the EOC (Embedded
Operations Channel) from a Model 3096RC G.SHDSL concentration card.
