Payload Loop
The Payload Loop is useful for looping back any testing initiated by the
other end of a point-to-point circuit, such as Payload, Serial Port, or
DSX-1 BERTs or any externally generated testing.
It is also useful for looping back Serial Port or DSX-1 testing initiated by
any remote location in an Integrated Access, Fractional-T1 circuit.
WHEN TESTING IS COMPLETED, BE SURE TO TURN THE LOOP
“OFF”.
