128Kbps ISDN Computer Terminal Adapter

Blazing￿ISDN￿Speeds

Connect to the on-line world at 128Kbps - four times faster than a 28.8Kbps modem. Cruising the Internet, downloading high volume data files, and LAN access from a remote site has never been faster or easier. And just in case 128Kbps is not fast enough, the Omni TA128 supports Hi/fntm LZS® (Stac®) and V.42bis compression for throughput speeds of up to 460.8Kbps.

Dual￿Action￿Performance

Dual analog and serial DTE ports allow the Omni TA128 to operate in either of two modes. In the default configuration, one DTE port and two analog ports allow the use of two external analog devices such as fax machines and analog modems. The second configuration provides two DTE ports and one analog port. In this mode two users can simultaneously access the Internet, each at 64Kbps, from a single ISDN data connection.

Universal￿Compatibility

PPPMultilink Protocol connects you with remote access servers at speeds up to 128Kbps, and can operate as a client or a server device. Bandwidth-on-Demand automatically adds and removes the second B channel based on data traffic. Additionally, Async to Sync conversion provides interoperability with router-based Internet services providers. The Omni TA128 is compatible with all popular operating environments including Windowstm 95, Windows NTtm, OS/2®, DOS®, Macintosh®, UNIX®, Novell®, Amiga® and any computer with a standard serial port.

Hands-Free￿Adaptability￿and￿Ease

ZyXEL's Multi-Auto feature automatically detects and accepts incoming data for PPP, V.120, X.75 and V.110, freeing the user from manual protocol configuration. The Multi-Auto feature also recognizes incoming data as either analog or digital.

Make￿the￿ISDN￿Connection

The Omni TA128 Computer Terminal Adapter is available with ISDN S/T or U interface. The S/T Interface model works with an external NT-1 (Network Termination) device and is ideal if you already use other ISDN equipment. The U Interface model saves money and desk space by eliminating the need for an external NT-1 device (North America only) .

Your￿Data￿is￿Safe

When security is a concern, rest assured that the Omni TA128 Computer Terminal Adapter is working for your peace of mind. With built-in password checking for up to 40 users, and three security levels, data safety is one less thing to worry about.

Hassle-free￿Troubleshooting

The Omni TA128's Embedded Protocol Analyzer is the perfect diagnostic tool for troubleshooting remote access connections. The data captured by the EPA is displayed in easy-to-read color text with any ANSI terminal program. Traveling to troubled remote sites may become a thing of the past.

Upgrades￿In￿A￿Flash

No need to replace equipment to keep up with today's rapidly advancing communications technology. The Omni TA128's Flash EPROM feature lets you download the latest features and firmware upgrades from ZyXEL's BBS, FTP and World Wide Web sites free of charge.
