Message Description
LOS at Network A Loss Of Signal condition (175 consecutive zeros) has been
detected on the network interface. The condition is cleared when
the density of ones to zeros received is 12.5%.
LOS at DTE A Loss Of Signal condition (175 consecutive zeros) has been
detected on the DTE Drop/Insert (DSX-1) interface. The condition
is cleared when the density of ones to zeros received is 12.5%.
OOF at Network An Out Of Frame condition (2 out of 4 frame synchronization bits
in error) has been detected on the network interface. The
condition is cleared when a reframe occurs.
OOF at DTE An Out Of Frame condition has been detected on the DTE
Drop/Insert (DSX-1) interface. The condition is cleared when a
reframe occurs.
AIS at Network An Alarm Indication Signal (unframed all ones signal) is being
received by the network interface.
AIS at DTE An Alarm Indication Signal is being received by the DTE
Drop/Insert (DSX-1) interface.
EER at Network An Excessive Error Rate condition has been detected on the
network interface. The condition is cleared when the error rate
falls below the threshold value.
Yellow at Network A Yellow Alarm signal is being received by the network interface.
Yellow at DTE A Yellow Alarm signal is being received by the DTE Drop/Insert
(DSX-1) interface.
Primary Clock
Failed The primary clock has failed. Timing for the DSU/CSU is provided
by the internal clock.
OOF at Port n An Out Of Frame condition has been detected on data port Port n
(where n is the port number). This condition only occurs if the
synchronous data port’s Embedded Data Link (EDL) is enabled.
