ISDN TA/V
If the call is answered by an ISDN TA/V, it begins to evaluate the type of
ISDN TA/V to which it is connected, the transmission protocol to be used,
and whether the remote ISDN TA/V will permit error correction, data
compression, etc.
Once this ISDN TA/V handshaking has finished, the outcome is reported
back to the computer in the form of a coded message. The front panel LCD
reports the line speed, accompanied by a statement of the error correction
type in use. For example,
Connected 64Kbps V.42
indicates a line speed of
64000 bps using V.42 error correction. This LCD message is also echoed to
your computer screen.
13.2 Using the Number Directory
Your ISDN TA/V uses a segment of its non-volatile memory to store up to
twenty frequently used ISDN numbers, and each storage location can hold
a maximum of 20 characters. Any one of these storage locations can later
be recalled, and the number dialed automatically.

Assuming that your ISDN TA/V is in command mode (your computer is in
terminal emulation and the ISDN TA/V is off-line) the command
&Zn=x
is
used to identify the directory location and ISDN number to be stored. For
example:
AT&Z6=12345678<CR>
will store in directory location 6 the number 12345678, and similarly:
AT&Z2=87654321<CR>
will store in directory location 2 the number 87654321.

The contents of your number directory can be displayed using the

command. We strongly advise that you use this command to check that all
stored numbers have been programmed correctly.
