ISDN TA/V
Not all of
Intro’s
features can be accessed in this way, and indeed
Intro
can
not be used at all when the ISDN TA/V’s operating configuration doesn’t
allow AT commands on the DTE interface. In these circumstances you will
therefore have to familiarise yourself with aspects of the AT command
language or management interface menu structure, since you are likely to
have to command the modem using a VT100 terminal connected to the
CONTROL
port.
Even in circumstances where you can use
Intro
to command the ISDN TA/V
(the DTE interface is operating asynchronously), you may need to comple-
ment the explanation given within
Intro
of any feature’s options, by reading
about the particular feature in this Reference section, and then going back
to
Intro
to make the appropriate selection.
