DIVA T/A ISDN Modem User’s Guide 111
When you pick up the phone you do not get a dial tone.
Make sure the ISDN line has voice capability. If you are using the S/T
version, try removing other ISDN equipment on the line. Try using a
different SPID and DN on the phone port. If the problem persists,
contact Eicon Technology.
The LINK LED does not go on.
Make certain that the cable in the ISDN connection has the right
interface: U or S/T.
Characters are missing when displaying VT100 screens or AT
command status
Refresh the screen by escaping the VT100 screen or re-executing the
AT command. If the problem persists, lower the COM port line speed.
Callers cannot access your VoiceMail
If you have a voice mailbox on your line and callers sometimes get a
busy signal rather than your VoiceMail box, do one of the following:
•
Windows 95/98/NT Users. Activate the “Enable voice mail”
option on the Configuration Tool’s Phone Lines panel. See page
39 for more information.
•
Windows 3.x/DOS. Use AT commands to correct the problem.
Do the following:
1 Start the terminal-emulation program (for example, Telix,
HyperTerminal, or HyperAccess).
2 Configure the terminal-emulation program to use the same
COM port that the DIVA T/A is connected to.
3 Confirm you are connected to the DIVA T/A by typing AT
and pressing Enter. The DIVA T/A should respond with
“OK”.
