INE
Loopback loops all of the received
data back toward the network. The transmitted data is the identical line code that was received, including
any bipolar violations.
P
AYLOAD
Loopback is similar to line loopback except that the framing is extracted
from the received data and then regenerated for the transmitted data.
N
ONE
disables the loopback test.
Default is
N
