Revision 1.6
16.3.2 Transmit data in progress
This signal indicates the port is transmitting data.
16.3.3 Receive data in progress
This signal indicates port receive activity.
16.3.4 Collision active
This signal indicates the port collision event detected by the port.
16.3.5 Full/Half duplex
This signal indicates the port duplex: active - full duplex, inactive - half duplex.
16.3.6 Receive Buffer Full
In order for this LED to be active, Rx Buffer Threshold must be enabled (see Table 4). This signal indicates the port re-
ceive buffer status: active - the buffer exceeds it's programmed threshold, inactive otherwise.
16.3.7 Forwarding of unknown packets enabled
This signal indicates the port mode of forwarding unknown packets: active - forwarding unknown packets enabled, in-
active otherwise.
16.3.8 The port is configured as Sniffer
This signal indicates if the port mode is configured as a monitor port: active - port is a source sniffer, inactive otherwise.
16.3.9 Link Fail State
This signal indicates the port link status: active - link is down, inactive - link is up.
16.3.10 Partition State
This signal indicates the port partition status: active - port entered partition state, inactive otherwise.
16.4
LED Signals Timing Type
16.4.1 Static LED Signals
These signals are stable for relatively long time periods. The LED indication directly reflects their current value.
16.4.2 Dynamic Internal Signals:
These signals are typically active for short time periods. In order to be visible through the LED Indication Interfaces, the
GT-48001A includes a "monostable" function per each of these dynamic signals so they can be viewed on the LED in-
dication output for a period of about 200 ms.
16.4.3
Table of Internal Activities/Status Driven via the LED Interface
The following table defines a bit by bit description of the internal signals driven through the LED Indications Serial Inter-
face. The bit number (bit#) refers to the activation of LEDStb. LEDStb is active for bit# 1. RESERVED bits contents is
not defined (i.e. can be either HIGH or LOW).
