QUESTIONS AND ANSWERS
What is line sharin
g
?
Line sharing lets you use one telephone line for more than one
purpose. For example, you can use one telephone line for reg-
ular calls, fax or modem transmissions, or calls to your an-
swering machine. Line sharing eliminates the need for
additional lines.
How does m
y
AFX-400 know that it’s a fax machine call-
in
g
?
When the AFX-400 answers a call (office mode) it listens for a
fax alert (CNG) tone. The CNG tone is a beep every three sec-
onds that most fax machines send to alert the receiving fax
machine.
How does m
y
AFX-400 know it’s a data modem callin
g
?
Unlike most fax machines, modems do not send an alert tone.
Modem calls must be routed using transfer codes (see “Using
Transfer Codes” on Page 8) or a distinctive ring service (see
“Using a Distinctive Ring Service” on Page 9).
Can I share m
y
residential line with m
y
fax machine?
Yes. You can install the AFX-400 at any modular telephone
jack on the telephone line. To prevent calls on extension
phones from interrupting your fax transmission, we recom-
mend you install a voice data guard (see “Installing an Option-
al Voice Data Guard” on Page 5).
Can I use the AFX-400 on a two-line s
y
stem?
Yes. The AFX-400 works on a two-line system, but only on the
line it is connected to. It does not alter the operation of the
second line.
Can I still send faxes like I did before I installed the AFX-
400?
Yes. Installing the AFX-400 does not affect outgoing fax oper-
ation.
Is there an
y
special information I need to know about re
-
ceivin
g
faxes from a fax machine that uses auto-dial?
Yes. Auto-dialing fax machines must connect with the receiv
-
ing fax machine usually within about 35 seconds. Otherwise
,
the transmission ends. This means the combined number o
f
rings between the answering machine and your fax machine
/
fax modem should not exceed five rings. For safety’s sake, al
-
ways set your fax machine/fax modem to its lowest ring dela
y
and/or ring number setting. Also, if you frequently receive fa
x
calls from overseas, you must allow extra time for the call t
o
connect (which means using an even lower number of com
-
bined rings).
Does the AFX-400 work with an answerin
g
machine tha
t
has a toll-saver feature?
Yes. In home mode, the toll saver will function normally an
d
you will not be charged for the call if you hang up before th
e
answering machine answers. But when the AFX-400 is in of
-
fice mode, it answers the call. Therefore, you will not save th
e
toll and you will be charged by the phone company when dial
-
ing from pay phones and long distance.
Does the AFX-400 work with Call Forwardin
g
?
No. If you have forwarded your phone to another number, in
-
coming fax calls never reach your AFX-400 because the call
s
are switched at the phone company’s central office to the for
-
warded number.
Does the AFX-400 work with Call Waitin
g
?
Yes, but the Call Waiting signal might distort an incoming o
r
outgoing fax or data transmission. Some telephone system
s
let you temporarily turn off the call-waiting feature by dialing
a
special code. You might want to do that if you send or expec
t
to receive an important fax call. Ask your phone company if i
t
offers this feature.
