Device Health and Status Messages
Internal failure in the TDM/Flex is detected.
No reply from TDM/Flex. The DSU periodically polls the TDM/Flex for health and status.
When the DSU does not receive a response, the message MUX CommunicFail
appears in the Health and Status report.
Transmitter at port nnn (01 or 02, or All is disabled. (Go to the Control branch to enable
the port.)
The DTR lead at port nnn (01 or 02, or All) has been Off for more than 30 seconds.
Streaming terminal. DTE at port nnn (01 or 02, or All) has its RTS lead turned ON
longer than the predefined time.
The DSU is running a test on port nnn (01 or 02), initiated from init .
test is one of the following tests:
BERT — Bit Error Rate Test
DL — Digital Loopback
DT — Digital Test
DTE — DTE Loopback
RL — Remote Digital Loopback
TM — Test Mode
init is one of the following initiators:
DTE — Data Terminal Equipment
FP — Front Panel (the DCP)
NMS — Network Management System
Remt — Remote DSU
Indicates a problem with the fan on the – 48 Vdc Central Office Power Unit.
Indicates a problem with the power on the – 48 Vdc Central Office Power Unit.
A major alarm was set Off by one of the devices in your subnetwork. Check the
Subnetwork Health and Status report.
The DSU is operating at a dial backup speed that is less than the DDS network speed.
Downstream health and status information has been truncated because it overflowed
system limits.
For DSUs operating on a single port (rate adaption or nondisruptive), TDM, the local
DSU has detected a continuous MUX Out-of-Frame condition. The alarm clears when a
local DSU synchronizes with a remote DSU.
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.
Indicates the speed ( nn.n ) of the active core (DSU or DBM) when there are no alarms.
