DTE/Network Loopback Test

Use the DTE/NETWORK Loopback test to verify the data port and
associated cabling. This bi-directional loopback loops the received data
port signal back to the data port and the received E1 processor signal back
to the E1 network. It can test a problem whose source is the E1 line.

LOCAL Loopback Test

Use the LOCAL Loopback test to verify the operation of the DL3800E unit
data port and its connections.

To receive valid test data at the DTE device, run LOCAL Loopback on all
active E1 ports.

NOTE: The following 3 tests interrupt payload traffic to the unit.
