Faultfinding
After starting the connection as described above one should see:
a) The dial up networking connection dialogue shows the normal progression of
"dialing" "verifying user name and password" and "registering your computer
on the network"
b) The real time status indication on the terminal should show "Registering" then
"Registered"
c) Once a "Connect" has been received from the host the Modem display/ISDN
Handset will show "Connected".
d) The connection should be established and usable after the completion of
PPP negotiation.
Error and clear cause logging on the vtLite application window
The terminal includes call logging and a record of any errors that occur. To assist
with improving the system please note the contents of these if a problem is
encountered.
C/No display Signal Strength Indication
For data communication it is of major importance that the mobile has a high
enough Carrier-to-Noise Ratio (C/No) before the call is established. (a voice call
is not as sensitive to this as a data call).
Before establishing any sort of data call (HSD or MPDS) verify that the display in
vtLite indicates minimum 535.
