Repeater Loopback
The local Repeater Loopback (RLB) loops data received from the user data port
after the signal has passed through the framing circuitry. Use the RLB to ensure
that all of the data is correct up to the point where it is sent over the interface. This
helps to indicate that the FrameSaver unit is operational.

Network Physical Tests
An attached device or test equipment should generate and monitor data to be
looped back.
The FrameSaver unit will not respond to any messages from the network during
this test.
CAUTION:
This test may affect the operation of the frame relay PVCs assigned to
the selected port. While in loopback, the frame relay link will be down so
any IP data being sent while this test is active will be disrupted.
An RLB cannot be started when one of the following tests is active:
Payload Loopback, Send Remote Line Loopback, or an active Monitor Pattern
on this network interface.
