A major alarm was set Off by one of the devices in your subnetwork. Check the
Subnetwork Health and Status report.
Subtree Truncat
Downstream health and status information has been truncated because it overflowed
system limits.
OutofFrameThresh
For DBMs operating on a single port (rate adaption or nondisruptive), the local DBM
has detected a continuous Out-of-Frame condition. The alarm clears when a local DBM
synchronizes with a remote DBM.
On a point-to-point circuit, if the alarm continues and the local DSU is configured for
automatic backup, the local DSU disruptively tests the DDS circuit. If the test fails, the
local DSU initiates a DDS Facility Alarm and initiates dial backup.
nn.n DDS
Indicates the speed (
nn.n) of the DSU core when there are no alarms.
nnn Disable
Transmitter at
nnn (DSU or DBM) is disabled. (Go to the Control branch to enable the
DSU or DBM.)
nnn DTR Alarm
The DTR lead at
nnn (DSU or DBM) has been Off for more than 30 seconds.
nnn StreamTerm
