T-Pieces are used to monitor live G.703 circuits for billing, signal level testing and load balancing. They pass the circuit to be monitored un-attenuated via two ports with the third port providing access for monitoring the passing traffic. The signal level on the monitor port may also be un-attenuated but is often attenuated by 20 to 30dB to provide isolation between the passing signal and the test point.
T-Pieces may be located at any desired connection point in the signal path.
AC&E T-Pieces are available with BNC, 1.6/5.6, BT43, 1.0/2.3 and SMB coaxial connectors.
