Not Enabled After 15 State Items
Error Messages and Fault Isolation
There are certain hardware and software exception conditions that will result in the
port being disabled and a state item being posted. To avoid logging redundant errors,
TL3 does not re-enable ports which have had 15 state items. For more information,
refer to the “State Item” error message.
Output External Interrupt
An external interrupt (EI) was active on the output data lines and the PP chain
executed a Read EI command. Execution of Read EI forces an input operation in
which two bytes of EI data are returned from the interface. This error applies only to
the SU00057 and 16-bit Parallel options.
Output Status Error Expect xxxx Actual xxxx [Other xxxx]
The expected output status did not match the actual status. Other (if applicable)
provides additional status information; for example, on a multiline line module Other
might indicate the specific line where the error occurred. Refer to “Line Module
Status Conditions” in this section for information.
Output Transfer Count Error
The expected output transfer count did not match the actual transfer count. Usually
this error will be associated with a status error; in this case, look at the status error
and perform the corrective action.
If this error is received by itself, there is likely a line module hardware or port
problem.
To check the line module hardware, retest the line module using an internal loopback
test.
• If the test is successful, the original error was probably caused by a faulty
external element (for example, a modem) in the transmission path. To isolate the
faulty element, progressively test each element in the path.
• If the test failed, check the port.
