ISDN TA/V
• Will Not Answer Incoming Calls
Using the factory-default configuration, the auto-answer facility will be
enabled on DTR, and you should check that this has not been altered (refer
to the Reference section for details). Other possibilities are that the ISDN line
or socket may be faulty, or the ISDN TA/V may not be connected to the ISDN
socket at all.
Note that the front-panel LCD identifies an incoming call by displaying:
INCOMING RING
If this is not displayed when the remote device calls your TA/V, it indicates
that the call is not reaching your incoming line.
• The ISDN TA/V Connects with the Remote Device but Locks Up
Ensure that the ISDN TA/V-to-computer flow-control method being used is
correctly configured into the communication-software program’s operating
parameters. By default your ISDN TA/V uses hardware flow control
(RTS/CTS). If this is incorrectly set, data may be interpreted as a flow- control
character, stopping the flow of data.
• The ISDN TA/V Disconnects While it’s On-line
Check for any loose connections between your computer, the ISDN TA/V,
and the ISDN line wall socket. Excessive line noise or interference may also
cause an interruption to the ISDN TA/V signals, in which case you should try
dialing the connection again. If this problem persists, contact your ISDN
TA/V supplier for help.
