095 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
100 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.
Determining the moment of a com-
munication interruption from the
remote device(s).
