12.2.2 Transmit data in progress
This signal indicates the port is transmitting data.
12.2.3 Receive data in progress
This signal indicates port receive activity.
12.2.4 Collision active
This signal indicates the port collision event detected by the port.
12.2.5 Full/Half duplex
This signal indicates the port duplex: active - full duplex, inactive - half duplex.
12.2.6 Receive Buffer Full
In order for this LED to be active, Rx Buffer Threshold must be enabled (i.e. the GT-48006A must be in fixed buffer allo-
cation mode.) This signal indicates the port receive buffer status: active - the buffer exceeds it's programmed threshold,
inactive otherwise.
12.2.7 Link Fail State
This signal indicates the port link status: active - link is down, inactive - link is up.
12.2.8 Pure Port Status LED
This signal will be inactive for the following event:
Link Integrity Test Failed
Otherwise, this signal is active.
12.3
LED Signals Timing Type
12.3.1 Static LED Signals
These signals are stable for relatively long time periods. The LED indication directly reflects their current value. The stat-
ic signals are:
500ms
5 seconds
Link Integrity Test Fails: Primary Status LED Blinks 500ms every 5 seconds
