DSX-1 Repeater Loopback

"
7970-A2-GB20-00
DSX-1 Repeater Loopback loops the signal being sent from the data port back to
the data port. In a T1-to-V.35 Repeater Loopback, the data signal is also sent to
the DSL port; in a T1-to-T1 Repeater Loopback, an Alarm Indication Signal (AIS)
is sent to the DSL port.
Activating the DSX-1 Repeater Loopback test causes the Embedded Operations
Channel (EOC), used for management, to be lost to the remote unit.
