Introduction

The ZyXEL omni.net series ISDN Terminal Adapter family includes
four ISDN Terminal Adapters; omni.net, omni.net Internal, omni.net
data, and omni.net Data Internal.
When used with off-the-shelf Internet or remote access client
software, the omni enables mobile or home users to connect to the
Internet or branch offices over ISDN lines Hassle Free! Some models
also allow you to connect to the analog world via a modem, fax
machine, or telephone connected directly to the TA.
To take advantage of constant new developments, the omni employs
flash EPROM. This allows for convenient uploading of newly
available firmware, effectively extending the life of your hardware
investment.
The omni 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, V.120, V.110, PPP Async-to-sync
Conversion and Bundle (128Kbps).
ZyXEL has also brought its world renown expertise in data
compression to the omni. With V.42bis compression on the B
Channels using either X.75, V.120, or STAC/LZS compression over
PPP/MP the omni can effectively communicate at speeds up to
460Kbps over ISDN lines.
The omni.net, has two analog ports, and the omni.net Internal has
one analog port for handling fax machines, modems, and telephones.
The omni.net allows different analog devices to 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.
