Reference Figure 3-10 and use the following procedure to connect the OC-3

 

 

ATMProbe to an OC-3 ATM network with a momentary interruption to service:

 

 

 

NOTE

If the output of the probe’s OC-3 ATM Interface is transmitted into a multi-mode

 

 

fiber without using a 10db attenuator, it can saturate the receiver’s photodiode and

 

 

cause bit errors, but no damage can occur. You can order a set of 2 10dB

 

 

attenuators from Agilent (Agilent J2928A).
