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.
