Keep following rest of install instructions.

Check Event Viewer for any error messages. This will let you know if you
have a conflict or problem. For Datafire BRI ISA or PC/IMAC try another
I/O or Memory addres (PC/IMAC only), no IRQ is used with this driver. Or
use Windows NT Diagnostics to check for hardware conflicts. If NT Diags
reports a conflict change to a non-conflicting address (Datafire BRI PCI
adapter does not support changing it settings at this time, change the
other adapters settings)

If the Digi ISDN driver loads then ISDN ports can be found either
Win NT 4.0, Dial Up Networking, Dial Using do you see ISDN1, ISDN2, etc.
Win NT 3.5.1 Remote Access phone book, Port do you see ISDN1, ISDN2. etc.

For Datafire BRI ISA or PC/IMAC run dginfbri.exe diag. (see next section)

For Datafire BRI PCI go to Control Panel -> Network -> Aadapters ->
Datafire BRI PCI -> Properties -> Check line status

* Make sure you are running latest Digi ISDN Win NT driver
* Before you install the driver make sure that either a network card
  or the MS Loopback Adapter is installed
* Check Windows NT Diagnostics -> Resources for hardware conflicts
* Reseat Digi adapter or try another slot. Move away from PCI shared slots.
* Use I/O ports 350 for Datafire BRI ISA and 320 for PC/IMAC
* Sound boards may cause conflicts remove sound board and retry
* Remove Digi ISDN Win NT driver, reboot, then reload
* If all the above suggestions fail, call, fax, or email Digi Tech Support

An NT1 (network terminator 1) is a device which provides an interface between the two-wire twisted pairs used by telephone companies in their ISDN Basic Rate (BRI) network and an end-user's four-wire terminal equipment. Any Digi Intl ISDN product with a S/T interface will require an extrenal NT1. Any Digi Intl ISDN product with a U interface will already have a built in NT1.

In North America, you have to buy and maintain your own NT1 device. The telephone company offers end-users a U interface. In Europe and Japan, the telephone company provides the NT1, owns it, and offers end-users a S/T interface directly. In North America, some ISDN equipment vendors offer devices which connect directly to the U interface (for example, the Datafire U). If you have one of these devices, you don't need to buy a separate NT1. The U interface can't be built in to the device when it's offered for sale in Europe or Japan.

(NT Server) Control Panel -> Network -> Services -> Remote Access Service

100 OHM termination switches for DataFire (SW2):

Datafire S/T Dip Switch SW2
The factory setting of SW2 is down, by default this places 100 ohm
terminating resistors across the transmit and receive lines. In the
event that another device is installed on the same BRI line, only one
device should be terminated. If the other device's termination can not
be easily disabled, reposition SW2 dip switch.
 
Datafire S/T4 Dip Switch SW2
The factory setting of SW2 is down, by default this places 100 ohm
terminating resistors across the transmit and receive lines. In the
event that another device is installed on the same BRI line, only one
device should be terminated. If the other device's termination can not
be easily disabled, reposition SW2 dip switch. Switch 7 & 8 used for
Port 1, Switch 5 & 6 for Port 2, Switch 3 & 4 for Port 3, Switch 1 & 2
for Port 4.

It indicates either a PPP authentication problem (PAP, CHAP, etc.) or Using Async PPP or V110/V120 protocols which are not supported (only sync PPP)

The ability to do a 2 channel call back only works when using Win NT 3.5.1 with (SP3) Service Pack 3. It is not yet working in Win NT 4.0 with any service packs.

The Datafire BRI and PC/IMAC adapters are not ISDN modems. they are more like ISDN ethernet boards.
You do not use AT commands with them. Digi uses Microsoft's Dial Up Networking GUI to make or receive
calls. If you are connection to a device that requires a terminal screen for entering additional connection info.
Under Dial Up Networking Phonebook properties has an option for using a script. Modify default script to
do the things done normally from terminal window.
