Per Port
RX Green Off 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
S8700
Multi-Connect
if only VBR (variable bit rate)
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 S8700 Multi-Connect if
CBR (constant bit rate) 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.
RPRD Amber Off Normal state
Power Supply AC OK Green Steady on Normal state. AC power is okay.
DC OK Green Steady on Normal state. DC power is okay.
