INSTALLATION
For example, if you connect your ATX-
250 in the following way, it will not
function properly:
Ringing will be heard in the background if
a call is answered by one of the
extension phones. Also, your ATX-250
cannot prevent an extension phone from
being lifted and interrupting a FAX call.
For the same reason, party lines and off-
premise extensions (OPX), including
answering services located away from
your building, are not compatible with
your ATX-250. Do not install an ATX-250
if you are on a party line or have an OPX.

Your ATX-250 is intended for use with
standard modular RJ-11 jacks.
Many
key system station jacks look the same,
but are not wired for the RJ-11 standard.
In addition, some ground-start PBX
trunks are incompatible. Neither an ATX-
250 nor a FAX machine will operate if
connected to this point.
The general rule is: if a SINGLE-LINE
telephone will work on the connector,
your ATX-250 will work. You can usually
use a telephone line tester to verify that
the jack is wired for RJ-11.

Manual transfers are accomplished by
entering touch-tones or dial pulses.
Some multi-line key systems do not allow
tone or dial pulse generation on incoming
calls. To determine if the key system is
capable of manually transferring an incoming
call, call the line on which you wish to in-
stall your ATX-250 from another location,
and listen to determine if the person who
answers can dial touch-tones.
Pulse-dialing telephone equipment and
some key systems do not generate the
*
or
#
signals. You can overcome this
limitation by changing the ATX-250
device selection codes to new codes that
do not contain
*
or
#
. See
section 6.1
to change device selection codes.
On a few key systems, dialing
* #
will
unlock the key pad to once a ain dial
touch-tones. Try dialing
* # * 2
, for
example, to manually transfer to your FAX
machine.
On some key systems that do not allow
tone generation on inbound calls, you
can fool the telephone system into
thinking it is making an outbound call by
pressin the “FLASH” key, and then
dialing * 2 To keep from hanging up
the caller, activate the “Protected Hook
Flash” feature. See
section 6.3.
