Displays the alarm history for the T1 interface. An asterisk in a field indicates that an alarm has occurred

LB
Loopback of the local unit. Choices are
N
ONE
,
L
INE
,
and
P
AYLOAD
.
L
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.
L
INE
loopbacks tests right up to the T1 interface of the ADTRAN unit.
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.
P
AYLOAD
loopbacks not only verify the T1 circuit, but also the internal
hardware of the local ADTRAN device.
N
ONE
disables the loopback test. Default is
N
ONE
.

EM
LB
Sends a loopback command across the network to a remote unit over the FDL, which causes the remote
unit initiate a local
L
INE
or
P
AYLOAD
loopback (whichever is specified). The remote loopback is only
available when the T1 is configured for ESF mode.

TATUS
Indicates whether a test is in progress.
LOS
Loss of Signal. No signal detected on port interface.
RED
Not able to frame data received on the port. Alternately referred to as Out of
Frame (OOF). RED alarm most frequently occurs when there is a framing
mismatch on the T1 interface.
YELLOW
Remote alarm indicator (RAI) being received on port. A YELLOW alarm indicates
that the remote unit is not receiving properly framed information from your unit.
BLUE
Receiving unframed all ones from the port alarm indicator signal (AIS). A BLUE
alarm is sent to notify the unit that equipment upstream is disconnected or
malfunctioning.
