Introduction
The DIVA T/A is an ISDN PC CARD (PCMCIA) modem available in
S/T and U interface versions. It provides easy and affordable highspeed Basic Rate Interface (BRI) ISDN connection to the Internet or
to your office LAN. With the DIVA T/A, Small Office Home Office
(SOHO) users and telecommuters can combine the higher
performance of ISDN with the simplicity of a terminal adapter.
The DIVA T/A emulates a COM port on your computer, which
complements your TCP/IP application (without the need for additional
device drivers). The DIVA T/A supports all standard modem AT
commands.
Internet Access
The DIVA T/A allows you to connect to the Internet over an ISDN
line at speeds of up to 128 kilobits per second. Without virtually any
delays, you can access online services or browse the World Wide
Web to download high-resolution graphics, video clips, interactive
games, music, etc.
Work-at-Home Access
The DIVA T/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.
Ease of Use
You can install the DIVA T/A into any computer (PC or notebook)
equipped with a PC Card Type II slot. You can easily configure it
using the Setup Wizard (under all versions of Windows), using a
VT100 interface (under DOS and OS/2), and using AT commands
(under all platforms).
In North America the Configuration Wizard (Windows 95 and
Windows NT) can automatically detect your Service Profile
Identifiers (SPIDs). SPIDs are addresses assigned by your ISDN
provider; the ISDN switch uses SPIDs to identify your equipment.

Ordering your ISDN Line Using
EZ-ISDN/IOC
(North America only)
We highly recommend that you use our toll free ISDN ordering
service to make sure you get the correct ISDN line the first time. This
service is free to our customers. Dial 1-888-800-DIVA.
EZ-ISDN / IOC simplifies the ordering of your ISDN line. It lets you
use simple codes to order pre-configured packages of ISDN features
and services.
The North American ISDN User’s Forum (NIUF) and Local
Exchange Carriers (LEC) administer the assignment of codes.
Bellcore administers the National ISDN Ordering Code (IOC)
process.
We recommend the use of the following ISDN Ordering codes:
EZ-ISDN: use ordering code 1
IOC: use ordering code R
If you want to use Always On/Dynamic ISDN (AO/DI) please refer to
www.isdnzone.com for information on how to order your ISDN line
(to be supported in a future software update).

resistor. Refer to “ISDN Line Termination” on page 78 for more
details.
DIVA T/A PC Card User’s Guide 8
After Connecting the Cables
Where AutoSPID is supported (check with your ISDN service
provider), the DIVA T/A installation is totally Plug and Play.
Continue at “What’s Next?” on page 10.
If your ISDN line does not support AutoSPID, get the following
information from your ISDN service provider before continuing the
DIVA T/A installation:
ISDN number(s).
Your ISDN service provider should have provided you with one
or two ISDN numbers. These numbers are required to configure
the DIVA T/A.
SPIDs
If you are installing the DIVA T/A under Windows 95 or
Windows NT, the ISDN numbers are all that you require as the
SPID Wizard, used for configuring the DIVA T/A, will
automatically configure the SPIDs.
If you are not using Windows 95 or Windows NT, you must get
your SPID information from your ISDN provider. SPID(s) are
numbers usually consisting of your 3-digit Area Code plus 7-digit
ISDN Number followed by some digits. For new ISDN lines your
local telephone company will likely follow the generic SPID
format of a 10-digit ISDN Number (Area Code and ISDN phone
number) followed by 0101. For example: 51455512340101.
You may not have to enter SPID information for the DIVA T/A to
function properly if your ISDN line is configured for noninitializing mode. The DIVA T/A features automatic noninitializing mode support, which enables the interface to operate
without programming a SPID, or to retain basic service if SPID
initialization fails. However, your local telephone company has to
turn this feature on. As you lose functionality, we do not
recommend this operation mode.
Go to the section “What’s Next?” on page 10 and continue.

Windows NT 4.0
Note: Before you begin installing the DIVA T/A, we suggest that the
Remote Access Service (RAS), also known as Dial-Up Networking, be
installed with at least one modem (any modem will do; it is only
needed to install the DIVA T/A and can later be removed).
1
Shutdown Windows NT and turn off your PC. After connecting
the cables (see “Connecting the Cables” on page 8), insert the
DIVA T/A, label side up, into the PC Card slot.

Select Don’t detect my modem; I will select it from a list, then
click Next.
Important: Make sure that you select the choice above and do
not let Windows NT choose its own modem driver. If you let
Windows NT select the modem driver, you will not be able to
communicate with the DIVA T/A. You will then have to delete the
Windows NT installed modem and restart the install process
again from Step 4.

Windows NT 3.51
If you are going to use the DIVA T/A with RAS, RAS must already
be installed with at least one modem (any modem will do, it is only
needed to install the DIVA T/A and will later be removed). If this is
the case, follow the steps below. If you are not going to use RAS,
continue at “Installing the DIVA T/A Software” on page 20.

Using the Windows 95/NT Configuration Tool
This section shows you how to use the Windows 95/NT Configuration
Tool to create one or more configuration profiles.
About Configuration Profiles
A profile is a set of parameters that define a particular ISDN setup.
When you run the Windows 95/NT Configuration Wizard for the first
time, you configure a profile with the default name Profile 0. In
addition to this profile, you can configure two other profiles that
define different ISDN setups (corresponding to the needs of different
applications). You might, for example, configure profiles to match the
ISDN setup needed to connect to your office, your Internet Service
Provider (ISP), and CompuServe. When you need a particular ISDN
configuration, you simply select the appropriate profile. This saves
you the trouble of reconfiguring all your ISDN parameters each time
you switch applications.
Note: When you use the Configuration Wizard to configure a profile,
you cannot set Advanced ISDN parameters (default settings are
implemented). If you want to modify these parameters, use the
Configuration Tool.
A profile contains information about the following:
Protocol.
implemented a t the ot her e nd of t he c onne c ti on.
Primary Location.
telephone number(s), a nd SPID(s), as required.
Alternate Location.
telephone number(s), a nd SPID(s), as required.
Advanced.
Allocation Protocol/Ba ndwidt h on Dema nd (BACP/BOD), Data
Over Voic e ( DOV) , and Cost Reducti on Paramet ers. Thi s
information is optional.
Your ISDN protocol. It must match the prot oc ol
The primary location’s ISDN switch type,
The alternate location’s ISDN switch type,
Advanced ISDN parameters such as Bandwidth
About Primary and Alternate Locations
Each profile can contain a Primary and an Alternate location. If the
DIVA T/A cannot connect using the Primary location parameters, it
automatically tries again using the Alternate location parameters.
