Your ATX-250 is compatible with all dial-up MODEM
S
.
Usually, MODEM
S
are attached to the
DEVICE 2
connector of your ATX-250. Your ATX-250 will transfer
incoming calls to your MODEM when the calling MODEM
dials *2 (or another code, if re-programmed) after the
call has been answered by your Versa-Link. The data
protection feature prevents interruptions from other
telephone equipment.
If your MODEM is only used for out-bound communication,
you do not need to be concerned with the device
selection code for the MODEM.
The device selection code for your MODEM is best dialed
by the calling MODEM. For example, when calling into a
MODEM attached to
DEVICE 2,
with the A T X - 2 5 0 factory
programming, the dialing command for a Hayes
compatible MODEM would be:
I
A T D T 1 203 555 1234 ,,,,*2
I
The commas will generate pauses in the dialing MODEM.
The number of pauses may need to be changed to allow
enough time’for the call to be switched through the
telephone company, particularly if the calling MODEM is
dialing long-distance.
The selectable device codes can be reconfigured to add
security to any system. Your ATX--250 will restrict access
to only those callers who dial the right device selection
code. See section 6,
USER SELECTABLE FEATURES
,
to
change this code.
Some MODEM
S
cannot dial the
*
symbol. Therefore, if
you plan to connect a computer MODEM, it is best to
choose a device selection code for your computer that
does not use the
*
symbol.
