If the Terminal Identification process fails
If either the Directory Number or the Device Type are
invalid, the Terminal Identification Process fails and you
will have to repeat it. The Identification Process may fail,
for example, if the Directory Number is not associated
with the current port, if it is not unique, or if the Device
Type is not appropriate to the Directory Number.
Accessing the Call Setup Screen
Ø Choose ISDN CALL SETUP from the Main menu.
The CALL SETUP screen is displayed. This shows a list of
bearer capabilities and teleservices - the options available
depend upon the protocol you are using.
Selecting a Channel for Testing
When you make a call, aurora
Duet
uses the currently
selected channel. You can select a specific B channel or,
in TE mode, you can set up aurora
Duet
to use any available
B channel ( Bx ).
You cannot connect a call on the D channel unless you
have X.25 installed on your unit (see the Chapter 8 for
details), but on a Basic Rate fixed link you can perform D
channel BERT - see Chapter 4 Section 2 for instructions.
