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).

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.

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

detected on the fiber from the TN230X.
