1.1 About your TA
The Omni.Net Lite is an ISDN Terminal Adapter (TA) with S/T interface, equipped with two
phone ports for connecting to analog phones and/or fax devices. It also supports
supplementary services such as call hold, call transfer, call waiting and 3-way conference
calling. It can transmit data at the rate of up to 230 Kbps through the RS-232 cable to your
computer or terminal.
1.1.1 TA Features
The following sections describe features of the TA.

The TA supports a single BRI. A BRI offers two 64 Kbps channels, which can be used
independently for two destinations or be bundled to speed up data transfer.

The TA is equipped with two standard phone jacks for you to connect analog devices such as
telephones and FAX machines. It also supports supplementary services such as call waiting
and 3-way calling.

or reconnecting a B-channel in a bundle when necessary.

The TA can bundle multiple links in a single connection using PPP Multilink Protocol (MP/
MLP/MLPPP). The number of links can be either statically configured or dynamically
