| Condition |
|
| ||
MUX Device Fail | Internal failure in the TDM/Flex is detected. | ||
|
| ||
MUX CommunicFail | 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. | ||
|
| ||
Prtnnn Disable | Transmitter at port nnn (01 or 02, or All is disabled. (Go to the Control branch to enable | ||
| the port.) |
|
|
Portnnn DTR Alarm | The DTR lead at port nnn (01 or 02, or All) has been Off for more than 30 seconds. | ||
|
| ||
Prtnnn StreamTerm | Streaming terminal. DTE at port nnn (01 or 02, or All) has its RTS lead turned ON | ||
| longer than the predefined time. | ||
PnnnTst: test,init | The DSU is running a test on port nnn (01 or 02), initiated from init. | ||
| test is one of the following tests: | ||
| BERT | Ð | Bit Error Rate Test |
| DL | Ð | Digital Loopback |
| DT | Ð | Digital Test |
| DTE | Ð | DTE Loopback |
| RL | Ð | Remote Digital Loopback |
| TM | Ð | Test Mode |
| init is one of the following initiators: | ||
| DTE | Ð | Data T erminal Equipment |
| FP | Ð | Front Panel (the DCP) |
| NMS | Ð | Network Management System |

|
| ||
The DSU is operating at a dial backup speed that is less than the DDS network speed. | |||
|
| ||
Subtree Truncat | Downstream health and status information has been truncated because it overflowed | ||
| system limits. |
| |
|
| ||
OutofFrameThresh | For DSUs operating on a single port (rate adaption or nondisruptive), TDM, the local | ||
| DSU has detected a continuous MUX | ||
| local DSU synchronizes with a remote DSU. | ||
| On a | ||
| 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 active core (DSU or DBM) when there are no alarms. | ||
