T1/E1 port test modes

Model 2616RC T-DAC User Manual 

The 2616RC offers a number of diagnostics tools to test operation and performance of the T1/E1 ports and 
line. Diagnostics include DSX1 payload loop and DSX1 line loop. 

When activated, the received signal at the selected T1/E1 port, will be looped through the 2616RC (see 

). Typically the received signal is looped back for retransmission after it has passed through the 

device's framing function (framing is terminated and then regenerated).
