Probe Overview
This section provides some general information on the Agilent J3919A and
J3972A OC-3 ATMProbes.
CAUTION Since the OC-3 ATMProbe repeats the received signal, a loss of power to the
probe results in an interruption of the network signal on the monitored fiber link.
To eliminate this possibility, you must install the optional Optical Bypass (Option
125).
