Introduction Page 1
One - Introduction
The ZyXEL Omni TA128 ISDN Terminal Adapter sets a new price/performance standard
for the explosively growing Internet and telecommuting applications.
When used with off-the-shelf Internet or remote access client software, the Omni TA128
enables mobile or home users to connect to the Internet or branch offices over ISDN lines
Hassle Free! The same device also allows a user to connect to the analog world via a
modem, fax machine, or telephone connected directly to the Omni TA.
To take advantage of constant new developments, the Omni TA128 employs flash
EPROMs, which allow for convenient uploading of newly available firmware which
preserves your hardware investment.
ZyXEL’s expertise in data compression has been brought to the Omni TA. With its
V.42bis compression and Hi/fn™ LZS®Compression on the B Channels, the Omni
TA128 can effectively communicate at speeds up to 460Kbps over ISDN lines.
The Omni TA128 also has two analog ports to connect analog devices such as fax
machines, modems, and telephones. Two different analog devices can communicate over
the two B channels to two different locations simultaneously, so you can send a fax and
make a voice call at the same time. The analog ports also recognize standard DTMF tones
as well as pulse dialing.

ZyXEL Omni TA128 Quick Start Guide
Driver Installation and Configuration Page 11
CONFIGURATION SETTINGS SCREEN
Click the icon to open the “Configuration Settings” screen.
Use this screen to make the following configuration choices:
Outgoing Protocol Control
Choose from the “Outgoing Protocol Control” pull down menu:
 PPP - Select PPP (Point to Point protocol) if you intend to use Windows’ dial-up
networking capabilities for applications such as Internet or remote LAN access.
 V.120 - Select V.120 (terminal mode) if you intend to use the Omni TA128 with
any standard terminal applications.
 MultiLink PPP/Multiple Link – Checking this box will enable the Omni TA’s
ability to bond both ISDN B channels to double its data throughput capability.
 Stac/V.42bis compression - Checking this box will enable the Omni TA’s data
compression feature.
Data Rate
 56/64Kbps - The Omni TA128 supports 56 and 64Kbps ISDN data rates. Contact
your telephone company if you are not sure which data rate your ISDN line
supports.
 Data Over Voice - Checking this box will configure your Omni TA128 to make a
56Kbps data call using a voice channel, which is often less expensive. The device
you are calling must also support data over voice to use this feature.
Preferred B Channel for out going call
 This feature allows you to define the B channel the Omni TA128 will use to initiate

Omni TA128 Quick Start Guide ZyXEL
Page 12 Driver Installation and Configuration
an outgoing data call. This feature is designed for customers who prefer to keep a
particular B channel available for voice calls. In the event the preferred B channel is
not available, the Omni TA128 will automatically attempt to make the data call on
the secondary channel.
PPP Setting
 Enable Call Bumping - Checking this box will enable the Omni TA’s Call bumping
feature. This feature will automatically reallocate bandwidth to allow you to make
or receive a voice call while a MultiLink PPP call is active (both B channels are in
use for data service). Thus, if you left the handset to make an outgoing call or
receive an incoming call, one B channel will be temporarily removed from the
MultiLink call and used for the voice call.
 Keep Connection Alive – This feature will send random PPP packets to the remote
side when there is no data being transferred. This feature is designed to keep
connections active in the event the device you are dialing into has an idle timer
configured to drop idle connections.
Bandwidth on Demand
 The Bandwidth on Demand (BOD) feature allows you configure when both B
Channels should be bundled in one MP connection based on the amount of data
traffic. Setting the Add/Drop trigger settings to “0” seconds will cause the Omni
TA128 to always use both B channels.
ISDN SWITCH SETTINGS SCREEN
From the “Main Menu” screen , click the icon to open “Switch Settings”.

ZyXEL Omni TA128 Quick Start Guide
Driver Installation and Configuration Page 13
Wizard – Clicking the icon will start you down the SPID/Switch Wizard path.
This wizard will assist you in configuring you directory (phone) numbers, SPID numbers,
and switch type. In many cases, the Wizard will be able to automatically determine most
of the information needed to configure your Omni TA128 for use on your ISDN line.
Once the Wizard has completed gathering your ISDN line information, it will return you
to the “Switch Settings” screen.
If you prefer to configure your Omni TA128 entirely from the “Switch Settings” screen,
simply follow the steps below.
Use the information you gathered in Chapter Two - “Ordering an ISDN Line” to
complete the following steps.
Step 1: Switch Configuration
Select the switch type you will be using to communicate with the ISDN. The switch type
to use will be determined by your local telephone company when you order your ISDN
service. If you do not know the correct switch type, contact your local telephone
company and ask what switch type your area is using.
Step 2: Phone Number 1 & 2
Enter your phone numbers into the corresponding “phone Number” fields. Phone
numbers (or Directory Numbers) are provided by your telephone company when you
order your ISDN service. These are the numbers that are used for any of your normal
analog telephony devices such as fax machines, modems, or normal telephones.
Step 3: SPID 1 & 2
Enter your SPID (Service Profile Identifier Numbers) numbers into the corresponding
“SPID” fields. SPID numbers are provided by your telephone company to identify your
ISDN channel configurations to their phone switching equipment. Your telephone
service provider should provide you with 1 or 2 SPID numbers.
Note: Some Switch types do not require the use of SPIDs. If you are using a
switch type that does not require SPIDs (such as AT&T Point to Point),
these fields will be grayed out.
Step 4: Voice Calls Use
The “Voice Calls Use” fields are to specify which analog port (1 or 2) to ring when an
incoming analog call is detected on a specific B channel.
Step 5: Answer ISDN data Calls using
This feature allows you to define the B channel the Omni TA128 will use to answer an
incoming data call. This feature is designed for customers who prefer to keep a particular
B channel available for voice calls. In the event the preferred B channel is not available,
the Omni TA128 will automatically use the secondary channel to answer the data call.
Once you are done entering the information for this screen, click the OK button to save
these setting and return to the Main Menu.

Page 14 Driver Installation and Configuration
PHONE SERVICES SCREEN
From the “Main Menu” screen, click the icon to open “Phone Services”.
Use this screen to configure your Omni TA128 to use the supplementary voice features
you have subscribed to with your phone company. These could include Call Waiting,
Conference Calling, Call Transfer, Call Forwarding and Message Waiting.

 Check the Phone Ports you wish to enable the Call Waiting feature on under the
“Call Waiting Feature” heading. Your phone company may or may not have
supplementary voice features available for both B channels. Check with a phone
company representative for details.
Message Waiting Deactivation
 Checking “YES” will deactivate the Message Waiting Indicator feature (both
audible and visual) on the Omni TA. This will not disable your phone company
voice mail service.
