E1 LED Descriptions
TA3010 Front Panel LED Definitions
LED NAME DESCRIPTION
Power Indicates presence of power.
Boot After power up, the Boot LED will be on for
about 10 seconds while the TA3010 is booting.
LNK Link/Activity LED. This LED is lit if Ethernet
connection has been made. It is off when the link is
down (i.e., when no Ethernet connection exists).
While link is up, this LED will flash off to indicate data
activity.
FDX Full-Duplex & Collision LED. This LED indicates
whether the Ethernet connection is half-duplex or full-
duplex (FDX) and, in half-duplex mode, indicates
occurrence of data collisions. LED is on constantly for
full-duplex mode; LED is off constantly for half-
duplex mode. When operating in half-duplex mode,
the LED will flash during data collisions.
T1 T1. Not supported (see below).
E1 E1. When lit, indicates that unit is configured for
E1 operation. It is possible for the TA3010 to be
internally re-configured for T1 operation.
However, this is not recommended because this
change would leave one of the unit’s five
primary circuitry sub-units unused. If T1
operation is desired, it is far more efficient to use
a TA2410 unit than to re-configure the TA3010
unit.
PRI PRI. On if E1 line is of ISDN-Primary-Rate type.
ONL Online. This LED is on when frame
synchronization has been established on the
T1/E1 link.
IC IC LED is on when Internal Clocking is selected
in T1/E1 configuration.
LC Indicates Loss of Carrier.
LS Indicates Loss of Signal.
Test For testing purposes only.
