RS-232 interface no lon-
ger connected
–
–
The RS-232 line was removed
–
The connected RS-232 de-
vice was removed
–
Power failure of the connected
RS-232 device
Only interesting if the termination
of the connection was not intended
and the time of the disconnection
is to be determined.
096
Sporadic parity errors
–
Sporadically, parity errors occur
on the serial interface.
Check the wiring of the serial inter-
face. If the serial data line is rela-
tively long compared to the used
data rate, or the quality of the line is
not good, reduce the serial data
rate.
096
Sporadic stop bit errors
–
Data packets contain sporadic
stop bits errors.
Check the wiring of the serial inter-
face. If the serial data line is rela-
tively long compared to the used
data rate, or the quality of the line is
not good, reduce the serial data
rate.
097
Sporadic protocol viola-
tions
–
Sporadically there are long peri-
ods of "zeros" on the serial inter-
face.
Possible cause:
–
the serial data rate may be
configured wrong
–
there may be a short circuit on
the serial data line
–
a driver of a device connected
to the serial port may be de-
fective.
–
Check the device configurati-
on (serial data rate correct?)
–
Check the installation of the
serial interface.
–
If the serial data line is relative-
ly long compared to the used
data rate, or the line quality is
not good, if applicable reduce
the serial data rate
098
Sporadic noise
–
Possible cause:
–
the serial data rate may be
configured wrong
–
there may be a short circuit on
the serial data line
–
a driver of a device connected
to the serial port may be de-
fective.
–
Check the device configurati-
on (serial data rate correct?)
–
Check the installation of the
serial interface.
–
If the serial data line is relative-
ly long compared to the used
data rate, or the line quality is
not good, if applicable reduce
the serial data rate

There is no more data re-
ceived from the remote
device(s).
–
For one minute there was no data
received from the SHDSL connec-
tion.
Although data was received previ-
ously.

munication interruption from the
