FCC Part 15 Information

This device complies with Part 15 of FCC rules. Operation is subject to the following two

conditions:

1) This device may not cause harmful interference.

2) This device must accept any interference received, including interference that may

cause undesired operations.

This equipment has been tested and found to comply with the limits for a CLASS B

digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference in a residential installation. This

equipment generates, uses, and can radiate radio frequency energy, and if not installed

and used in accordance with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not occur in a

particular installation.

If this equipment does cause harmful interference to radio/television reception, which can

be determined by turning the equipment off and on, the user is encouraged to try to

correct the interference by one or more of the following measures:

 Reorient or relocate the receiving antenna.

 Increase the separation between the equipment and the receiver.

 Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

 Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by the party responsible for compliance

could void the user’s authority to operate the equipment. Shielded RS-232 cables are

required to be use

d to ensure compliance with FCC Part 15, and it is the responsibility of the user to

provide and use shielded RS-232 cables.

Foreword

Information for Canadian Users

The Industry Canada (IC, formerly DOC) label identifies certified equipment. This

certification means that the equipment meets certain telecommunications network

protective, operational, and safety requirements. IC does not guarantee that the

equipment will operate to a user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected

to the facilities of the local telecommunications company. The equipment must also be

installed using an acceptable method of connection. In some cases, the company’s inside

wiring associated with a single line individual service may be extended by means of a

certified connector assembly (telephone extension cord). The customer should be aware

that the compliance with the above conditions may not prevent degradation of service in

some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance

facility designated by the supplier. Any repairs or alterations made by the user to this

equipment, or equipment malfunctions, may give the telecommunications company cause

to request the user to disconnect the equipment.

For their own protection, users should ensure that the electrical ground connections of the

power utility, telephone lines, and internal metallic water pipe system, if present, are

connected together. This precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections themselves, but

should contact the appropriate electrical inspection authority, or

electrician, as appropriate.

The Load Number (LN) assigned to each terminal device denotes the percentage of the

total load to be connected to the telephone loop used by the device without overloading.

The termination on a loop may consist of any combination of devices, subject only to the

requirement that the total of the Load Numbers of all the devices not exceed 100.

This digital apparatus does not exceed the class B limits for radio noise emissions from

digital apparatus set out in the radio interference regulations of Industry Canada (formerly

Canadian DOC).

Chapter 1 - Introduction

The ZyXEL’s Omni TA128 ISDN Terminal Adapter (TA) 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 TA128.

With ZyXEL’s Common Application Programming Interface for ISDN published by

Telekom Roland in Germany, a user may run most commercially available ISDN

applications with the Omni TA128.

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.

The Omni TA128 supports both D and B Channels protocols. For the D Channel, it

supports DSS1, 1TR6, DMS-100, AT&T Custom, and NI-1. For the B Channels, X.75

SLP, V.120, V.110, PPP Async-to-sync Conversion and Bundle (128Kbps).

ZyXEL’s expertise in data compression has been brought to the Omni TA128. With its

V.42bis compression on the B Channels using either X.75 or V.120, the Omni TA128 can

effectively communicate at speeds up to 512Kbps 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.

Key Features of the Omni TA128

Speed and Compatibility

 Plug and Play support for Win95 environment

 Full compatibility with both ISDN and remote PSTN via ISDN

 Multiple signaling protocol compatibility with the following network switches: DSS1,

1TR6, NI-1, AT&T 5ESS, and Northern Telecom DMS 100

 Supports X.75, V.110, V.120, and PPP Async-to-Sync Conversion B Channel

protocols

 B Channel speed 56Kbps and 64Kbps

 112Kbps/128Kbps channel bundling (for DTE #1 only): MLP, CCB, and Multilink

PPP(RFC1717)

 V.42bis data compression using the X.75, V.120, and Bundle protocols
