Seconds in test
This read-only count represents the number of seconds the Quad DS-1 module was
in test.
State
This field shows whether the alarm is active or not.
ErrSec
This read-only count represents the number of errored seconds that occurred in a
one-second period while the T1 module was in test.
AIS
An unframed All Ones condition has been detected.
RED
A Loss of Frame Alignment has occurred and synchronization has been lost.
YEL
A Yellow Alarm is generated by the network and sent to the customer premises. It
usually means that the network is not receiving the AS4000 signalling correctly (i.e.,
the network is not in sync or a Red Alarm has occurred).
Ferr (framing
errors)
One or more frame alignment bit errors have been detected. This does not mean,
however, that synchronization has been lost.
CRC6
One or more CRC-6 block errors have been detected. The D4 framing does not
include CRC-6.
BPV
Bipolar violations have been detected. This usually indicates that a very weak or
excessively strong signal is being received from the network.
LOS
This indicates a loss of signal detection. No signal is present on the RX pair to the
AS4000 DS-1 module (T1 loop).
