Repeater Loopback
The Repeater Loopback (RLB) loops data received from the data ports and the
DSX-1 interface after the signal has passed through the framing circuitry. Use
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.
An attached device or test equipment should generate and monitor data to be
looped back.

The T1 NAM will not respond to any messages from the network during this test.
CAUTION:
Repeater Loopback 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.
A RLB cannot be started when one of the following tests is active:
H
Payload Loopback, Send Remote Line Loopback, or an active Monitor
Pattern on this network interface.
H
All loopbacks on any other T1 interface with DS0s assigned to this network
interface.
H
Send Pattern Test on this network interface or any synchronous data port
(Port Use set to Synchronous) assigned to this interface.
H
Send V.54 or FT1 Loopback, or Data Channel Loopback on any synchronous
data port (Port Use set to Synchronous) and assigned to this network
interface.
