No ATM cells are being received. This is not a
normal state if the terminating port network is
supposed to be up and running.
RX
Green
Intermittent
blink
ATM cells are being received intermittently.
This is a typical pattern for Avaya Definity
Server CSI if only Variable Bit Rate (VBR)
signaling connections are present but no talk
paths are up, perhaps because no calls are in
progress.
RX
Green
Steady on
ATM cells are being received frequently
enough that the LED is lit constantly. This is a
typical pattern for Avaya Definity Server CSI if
Constant Bit Rate (CBR) talk paths are
present.
CD
Green
Off
Loss of carrier on the fiber. The A500 detects
only if the A500-receive (right-hand) fiber is
not working. The state of the A500-transmit
(left hand) fiber is not detected.
CD
Green
Steady on
Normal state. There is a optical carrier
detected on the fiber from the TN230X.
