If a part appears damaged or missing, contact your nearest Ultra Switch 100
location immediately. Save all packing materials. Reuse the package for
mailing if you experience a problem.
STEPS TO GET STARTED
1. Remove the Ultra Switch 100 from the packing box. Stick the four rubber
feet to the edges of the Ultra Switch's bottom side to prevent possible
slide of this device.
2. Plug the connecting end of the 12VAC power adapter into the jack on the
rear panel of the Ultra Switch 100 labeled 12 VAC. Plug the other end of
the adapter into an AC power outlet. Once connected, the
POWER
indicator on the top of the Ultra Switch will light up.
3. Connect one end of the supplied phone cord to the jack labeled LINE-IN.
Connect the other end of the line cord to the incoming telephone line
(C/O line). Connection of the Ultra Switch 100 in various situations are
illustrated in Fig.1-2, Fig.1-3 and Fig.1-4. Connect your communication
devices to their associated jacks at the rear panel of the Ultra Switch 100
as illustrated in Fig.1-1.
4. The Ultra Switch 100 is now ready for use. Indeed, it works with the
default parameters set by the control program. If you want your Ultra
Switch 100 to work differently, you may use any tone phone connected
1

behind the Ultra Switch 100 to program new parameters for the desired
functions. Please refer to Chapter 3 for the instructions on function
programming.
If you have a Caller ID device, you may connect your Caller ID in front of
the Ultra Switch 100 or connect it to the phone port of the Ultra Switch 100.
When connecting in front of the Ultra Switch 100, you should set the "Rings
to Answer" to 2 or more rings (please refer to page 16, "Rings to Answer"). If
the Caller ID is connected to the phone port of the Ultra Switch 100, you
should declare the availability of the Caller ID by programming the "device
availability" of the Ultra Switch 100 (please refer to page 19, Function Code
"7").
Whenever the Ultra Switch 100 answers a call and starts ringing a parti-cular
extension, the LEDs corresponding to another two extensions will blink in
accordance with the ring cycles. When the extension is answered, the two
LEDs stated above stop blinking and the LED corresponding to this
extension lights up.
Note: In certain cases, a Caller ID device connected to the Ultra Switch
100 may display calls in a different manner. Nevertheless, Calle
ID information is kept in memory if the device has the capacity.
WARNING!
1. Never install telephone wiring during a lightning storm.
2. Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
3. Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
4. Use caution when installing or modifying telephone lines.

Ultra Switch 100 will generate a busy tone to remind you that the line is not
available for the time being. This "Barge-In Protection" facilitates
protection of any voice or fax/data call from being intervened by other
telephone equipment connected to the Ultra Switch 100.
If
unavailability of the C/O line described above, the Ultra Switch 100 will
inform you when the line is available. Indeed, after the line is released, the
Ultra Switch 100 will ring the phone connected to the Ultra Switch 100 one
time to advise that the line is now available for communication.

phone port to the fax port as stated above, it is quite natural to
assume that no one is in the room. The Ultra Switch 100, after
answering the next incoming voice call, rings your phone only
two times and transfers the call to the fax port. This allows a
caller, whose fax machine is not able to issue the CNG tone for
auto-switching, to send fax message to your fax machine. You
can restore the "Rings to Phone" by employing one of the
following operations through a telephone set that is connected to
the Ultra Switch 100:

CNG tone at all. In this case, the Ultra Switch 100 will not route the line to
the fax port because it can not distinguish this type of fax calls from the
regular voice calls. In order to receive fax messages that are transmitted from
these fax machines, the Ultra Switch 100 supports two other types of
switching to switch the line to the fax port. They are: (1) manual switching,
and (2) TAD-to-Fax switching.

When this TAD-to-Fax mode is activated, the Ultra Switch 100 will route
the line to the fax port after the answering machine (connected behind the
Ultra Switch 100) completes its operation ( i.e., answers the line, plays
the pre-recorded outgoing message, and records incoming voice message,
etc. ). Please refer to page 20 to enable this mode.
The TAD-to-Fax switching is useful to facilitate fax transmission from a
pulse-dial fax machine by which Fax Access Code can not be entered to
instruct the Ultra Switch 100 for fax switching. When this mode is on,
you may record the outgoing message to remind the fax caller to stay on
the line until the fax tone is heard.

To receive modem messages
Automatic Modem Switching ■
Whenever a calling modem issues the reverse modem tone to request a
9
data communication, the Ultra Switch 100 can recognize the reverse
modem tone and route the line to the modem port.
The method that requires
modem tone is called reverse modem communication. Unlike a fax
machine, a calling modem listens for a tone from the receiving
modem before sending its own tone. This, in turn, makes Ultra
Switch 100 unable to distinguish the caller's communi-cation type
and can not switch to the modem port as supposed. The reverse
modem detection, however, reverses the normal procedure fo
modem communica-tion. Indeed, the calling modem now issues the
so-called reverse modem tone to signal the receiving modem. As
result, the Ultra Switch 100 can notify a request for compute
communication upon reception of the reverse modem tone. In orde
to carry out reverse modem detection, modems on the calling site
and the receiving site must both be set for reverse modem activity.
Notice that not all modems are able to participate in reverse
modem communication. Refer to your modem's manual fo
function specifications, or contact the manufacturer to determine
whether your modem can participate in reverse mode
communication. Consult your modem's operation guide to fin
how to set the "Reverse Modem Communication" feature. Instruc

the Modem Access Code to instruct the Ultra Switch 100 that a computer

telephone company. This service assigns multiple phone numbers to a single
line, with each number having its own ring identity. Wo rking in conjunction
with this service, the Ultra Switch 100 identifies and directs the three ring
types to a designated extension port. This allows you to connect up to three
different telephone devices to a single telephone line without the burden of
remembering ring pattern of each number.

"Distinctive Ringing" service can support a wide range of applications
through a single line. For example, if you are a subscriber of the "Distinctive

the Ultra Switch disables the feature of automatic fax switching and
processes fax switching completely through manual switching. In other
words, when detecting the incoming CNG tone, the Ultra Switch disconnects
the line immediately. All the incoming fax calls must be processed manually
by entering the Fax Access Code. Likewise, when operating in the Modem
Filter mode, the reverse modem detection is disabled and routing to the
modem port can only be conducted by entering the correct Modem Access
Code. When operating in the Phone Filter mode, the Ultra Switch will block
the incoming voice calls unless # followed by a Phone Access code (page 21)
is entered within a certain time interval ( the time taken for issuing rings with
the number of rings equivalent to "Rings to Phone"; default: 5 rings, page
18 ). The caller will first hear three short beeps indicating that the Ultra
Switch is in the Phone Filter mode, and then a long silence during this
waiting (for Phone Access Code) period. If the Phone Access Code is not
entered correctly within this time interval, the Ultra Switch will route the line
to the fax port or disconnect the line depending on the operating parameters
set in the Ultra Switch. If the code is entered incorrectly, the caller may
press # first to delete the previous erroneous code and then enter the
correct code (Fax Access Code, Modem Access Code, or Phone Access
Code) to make correction.

switched on.
Note:
More than one Call Filter may be enabled simultaneously.
When the Fax Filter (Modem Filter) is switched on, the
Ultra Switch 100 will disconnect the C/O line
immediately if the CNG tone (reverse modem tone) is
detected.
3. TAD-to-Fax is useful when the caller cannot enter a tone
code to direct the Ultra Switch 100 to transfer the call to
the fax machine. In this case, you may pre-record an

4 TROUBLESHOOTING
a
Q & A
Probably the fax is from a machine which does not issue CNG tone. In
this case, the Ultra Switch 100 routes the call to your phone. After
answering the phone, you can identify this call as a fax call if no one is
on the line and then conduct manual switching to the fax machine by
dialing the Fax Access Code.
This is a fax call. Dial the Fax Access Code and hang up. The Ultra
Switch 100 will then route the line to your fax machine. If your telephone
company uses a pulse system, dial 1 to switch the line to the fax machine.
The TAD-to-Fax mode of the Ultra Switch 100 is activated. When the
TAD-to-Fax mode is enabled, and when the Ultra Switch 100 detects line
disconnection by the answering machine, it will transfer the line to the
fax port immediately. In other words, the call is always transferred to the
fax machine after the answering machine ends its operation. This will
take up to 30 seconds of delay (depending on how long your fax machine
ends its waiting state for fax reception) before the line is available again
provided that the caller disconnects the line instead of sending a fax. You
may use Function Restore to turn off TAD-to-Fax.
