BT NTU6 - Full Circuit Operation Test (64 kbit;s)

Testing the operation of the entire circuit (national
64kbit/s circuits)
To test the connection and operation of the entire circuit, you need to
apply a remote loop. Although the remote loop facility is not available
on 64kbit/s KiloStream circuits, you can simulate a remote loop by
contacting the distant end user and asking the user to apply a loopback.
On International KiloStream circuits it is not possible to call up a remote
loop from your NTU6. You will need to contact the distant end user and
ask them to apply a loopback.
