Introduction

Congratulations on your purchase of a ZyXEL Omni TA128. The
TA128 sets new price/performance standards for the explosively
growing Internet and telecommuting applications market.
When used with off-the-shelf Internet or remote access client
software, the 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 TA128.
To take advantage of constant new developments, the TA128
employs flash EPROM, which allow for convenient uploading of
newly available firmware, preserving your hardware investment.
The 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 SLIP, V.120, V.110, PPP Async-
to-sync Conversion and Bundle (128Kbps).
ZyXEL's expertise in data compression has been brought to the
TA128. With its V.42bis compression on the B Channels using either
X.75, V.120, or STAC/LZS compression over PPP/MP the TA128
can effectively communicate at speeds up to 460Kbps over ISDN
lines.
The TA128 also has two analog ports for handling 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.
