DIVA T/A ISDN Modem User’s Guide ◆ Page 5
Introduction
The DIVAT/A is an external ISDN modem available in S/T and U interface versions. It provides
easy and affordable access to the Internet via ISDN.
With the DIVAT/A, Small Office Home Office (SOHO) users and telecommuters can combine
the higher performance of ISDN with the simplicity of a terminal adapter. The DIVAT/A
supports all standard modem AT commands.
You can connect the DIVAT/A to a serial port on your computer that complements your
TCP/IP application, without the need for additional device drivers.
Internet Access
The DIVAT/A allows you to connect to the Internet over an ISDN line at speeds of u p to 128
kilobits per se cond. With virt ually no delays, you can access onl ine servic es or browse th e
World Wide Web to download high-resolution graphics, video clips, interactive games, music,
and more.
Work-at-Home Access
The DIVAT/A provides the telecommuter with fast access to network resources back at the
office. You can access applications such as email or download data from a remote database in
a fraction of the time it would take using a conventional analog modem.
Analog Device Ports (ce rtain models only)
Certain DIVAT/A models include two analog device ports (also referred to as Plain Old
Telephone Service, or POTS). You can use these ports to connect regular telephones,
modems or fax machines to your DIVAT/A. Calls to and from these analog devices are carried
over your ISDN line. This saves you the expense of installing a separate analog phone line.
The DIVAT/A supports a variety of calling features such as Call Forward, Call Waiting,
CallerID, Call Transfer, and Call Redirection. The available calling features, and the way each
feature works, depends on your location. See “Analog Device Support” on page 104 for
details.
Note: The DIVAT/A can work independently from your computer. If the DIVAT/A is turned
on, your analog devices can use your ISDN line regardless of whether or not the DIVAT/A is
connected to your computer.
Ease of Use
You can connect the DIVAT/A to any computer (desktop or notebook) equipped with a serial
port. Under Windows 95/98/NT and Macintosh (System 7 or later), you can easily configure
the DIVAT/A using the included DIVA Terminal Adapters software. For all platforms, the
VT100 Configuration Tool can be used as well as AT commands.
