PREINSTALLATION
To ensure a successful installation, we recommend that the installer prepare the
following items before proceeding.
1. Subscribe to ISDN from your telephone service provider. Refer to Appendix A for
a detailed explanation of ordering ISDN.
2. Select adequate communication software (HyperTerminal, Terminal, ProComm
Plus, etc.)
+Note: For the operation and installation of the communication software, please refer to the
communication software manual.
ØIf you want to use the AT Command Set with Windows 95/98/NT 4.0, then
HyperTerminal is the communications software supplied by Microsoft. (We
suggest using the Human to Machine Interface, or HMI, software instead of
the AT Command Set.)
ØFor Windows 3.X, DOS, or UNIX, we recommend using a terminal program
and the AT Command Set to configure the UTA120.
3. Have your personal computer (PC) or workstation ready if you plan to use the
UTA120 for data communication.
4. Check the packing list. If something is missing, call your UTA120 vendor.
5. Be sure to register your UTA120 to validate your warranty.
INSTALLING THE HARDWARE
+Warning: Always turn the UTA120 power off before connecting or disconnecting
cables.
1. Plug the DB9 cable into the UTA120’s DATA port. Insert the other end of the cable
into a communication port on the PC/workstation or other Data Terminal Equipment
(DTE).
2. Plug the RJ-11 cable into the UTA120’s U-Interface which is the protocol reference
point between ISDN network termination (NT1) equipment and the central office.
Insert the other end of the cable into the ISDN wall jack.
3. Plug the RJ-45 cable into the UTA120’s S/T-Interface. Insert the other end of the
cable into the ISDN S/T terminal equipment.
4. Plug another RJ-11 cable into the UTA120’s TEL1 and/or TEL2 port. Insert the
other end of the cable into any analog device (traditional telephone, modem, fax
machine or answering machine).
5. Plug the AC/DC power adapter into the POWER connector.
6. Secure the power adapter cord on the rear panel by using the attached hook on the
right side of the POWER connector.

Chapter 1: Introduction
UTA120 User’s Guide

7. Insert the other end of the AC/DC power adapter into the wall socket.
8. Check the Termination resistance setting. You may need to adjust the termination
resistor if your UTA120 is connected to any other ISDN terminal equipment,
especially ISDN phones. Position DIP switches 7 and 8 on the rear panel to set
the termination resistance. Refer to Table 1.1 for the appropriate DIP Switch
settings. In most cases, the default setting is 100Ω.
9. Please check the LED (Light Emitting Diode) indicators when you turn the power
switch ON. All the LEDs should flash in a preset sequence for a few seconds. If
nothing is plugged into the UTA120 then the LED indicators will stop flashing and
only the green Power LED and the red Line LED will be lit. If everything is
connected, the Line LED will turn green. For a complete description of the States
of the LED indicators, see Table 1.2.

CONFIGURATION
1. If you have just installed the UTA120 software, you will see the UTA120
window. Click on the “UTA120 Configuration” icon. The Configuration
window appears.
+If you have installed the setup software, but closed the UTA120 window, do the

ØHighlight/select and click on UTA120 Configuration.
2. Click the COM Port down arrow button to choose the port connected to the
UTA120.
3. In the section labeled Service Profile Identifiers - SPID, click inside the Tel
Port #1 window and enter a SPID. A SPID is the number that identifies each
terminal equipment to the Telephone Company. Notice that the SPID is
automatically copied to Data Port #1.
+Note: Your local phone company assigns SPIDs. Only the Data Port and the Tel Ports
can share SPIDs. The Tel Port or Data Port cannot share the same SPID with any S/T
devices.
4. In the section labeled Directory Numbers, click inside the Tel Port #1
window and enter the phone/directory number that corresponds to the Tel
Port #1 SPID window. Notice that the DN is automatically copied to Data
Port #1.
5. Repeat steps 2 and 3 for Tel Port #2.
+Note: You must enter a different SPID and Directory number than the SPID and
Directory number entered in Tel Port #1.
6. Speech/Fax/Modem (Tel Port #1 or Tel Port #2):
+If you choose Speech for either Tel Port, you can choose the Supplementary Services
function. If you choose Fax/Modem for either Tel Port, you cannot choose the
Supplementary Services function.
7. Data Call Protocol click the down arrow button to choose one of the
following:
ØHDLC Transparent (High-level Data Link Control) allows remote access
for the UTA120.
ØAsyn-to-Sync PPP (Asynchronous to Synchronous Point to Point
Protocol) allows 64Kbps or 128Kbps Internet access.

Chapter 2: Software Installation and Configuration
UTA120 User’s Guide

ØV.120 (Hardware Rate Adaption) is a North American setting that allows
the UTA120 to talk with older ISDN hardware.
8. PPP Option (Point-to-Point Protocol) is available only if you choose the
Asyn-to-sync PPP call type. You are given a choice for either 64Kbps or
128Kbps speed.
ØPPP 64Kbps is an ISDN Internet connection using one B-Channel for a
64Kbps data rate.
ØMLP 128Kbps (Multilink Protocol) is an ISDN Internet connection
combining both B-Channels for a 128Kbps data rate. Sometimes
described as PPP/MP (Point to Point/Multilink Protocol).
ØRelease a Channel for Voice Call allows bandwidth on demand. This is
only an option if you choose MLP 128Kbps.
+Example: You are accessing the Internet with both B-Channels (128Kbps). While you
are still on-line, you receive a voice call or decide to make a voice call. In this mode,
one of the B-Channels will drop allowing the call to go through, reconnecting when
the call is finished.
9. After you input the proper settings, click the Configure TA button. This
sends the new configuration to the UTA120 hardware.
+Note: This is now your active profile (i.e., the one you are using). It will not be stored
as a user profile unless you do so. SPIDs and DNs are kept separately from profiles
10. Click the Save Data button to store this configuration on your hard drive.
INSTALLATION AND CONFIGURATION FOR WINDOWS 3.X,
DOS, OR UNIX
