STA RX TX
The WSX-BRI module includes one
set of LEDs for each port. The LEDs
for a given port are located in the
set labeled with the port number. If
the HSX module contains two WSX-
BRI daughter cards, the second set
of ports (one Serial and one BRI)
are numbered as Ports 3 and 4
respectively, and include their own
separate set of LEDs that function
exactly like those related to Ports 1
and 2.

STA (Status). On Green con-
tinuously when the port con-
nection is operational. Off
when the port is disabled or
the cable is detached. Blink-
ing On/Off if cable is attached
but receive control data is
detected as down.
This LED also blinks during
initialization, diagnostics, or
when invalid data is being
exchanged on the port.

bright” Green when idle and
Green with occasional flickers
when the port is transmitting
data.

Green when idle and Green
with occasional flickers when
the corresponding port is
receiving data.
STA (Port 2/4 Status). On
Green continuously when the
port connection is operation-
al. Off when the BRI port is
