Figure 6-8. Data Channel Testing on In-Service T1 System  

Figure 6-9 shows an end-to-end test on a voice or program audio channel. For duplex voice channels, 
perform the test in each direction of the circuit. 

 

Figure 6-9. Voice or Audio Channel Testing on In-Service T1 System  

Figure 6-10 shows that you can perform local loopback tests on individual channel modules before 
putting a multiplexer into service by activating its equipment loopback or by establishing a local 
loopback using a T1 patch cord. You can only perform loopback tests on full-duplex 4-wire voice and 
data channels.
