Frequently Asked Questions (FAQ)Digi ISDN BRI products under Win NT - Last Update: (2/8/99) -------------------------------------------------------------------------------What ISDN BRI Win NT driver version is loaded and where can I get latest?Digi FTP (ftp.dgii.com) /support/drivers/winnt/released/isdn/For Datafire BRI ISA or PC/IMAC:Select Explorer -> Win NT directory/system32/drivers/pcimac.sys Properties - Version -> File Version should show v2.5.1(E)Datafire BRI ISA and PC/IMAC adapters latest driver is:ISDN Win NT 3.5.1/4.0 BRI ISA drv vers 2.5.1 filename: 4001119E.exe For Datafire BRI PCI Select Explorer -> Win NT directory/system32/drivers/DigiCBri.sysProperties - Version -> File Version should show 3.1.4Datafire BRI PCI (only) latest driver is: ISDN Win NT 3.5.1/4.0 BRI PCI x86 drv vers 3.1.4 file: 4001537D.exe 1 of 2 ISDN Win NT 3.5.1/4.0 BRI PCI x86 drv vers 3.1.4 file: 4001539D.exe 2 of 2 ISDN Win NT 3.5.1/4.0 BRI PCI Alpha drv vers 3.0.0 file: 4001550A.exe 1 of 2 ISDN Win NT 3.5.1/4.0 BRI PCI Alpha drv vers 3.0.0 file: 4001551A.exe 2 of 2 -----------------------------------------------------------------------------How do I install the Digi ISDN BRI Win NT driver?Before driver install: Make sure you have either a network card or the MS Loopback Adapter installed as an Installed Adapter Card.For Win NT 4.0 To Install: Control Panel -> Network -> Adapter -> Add -> Have DiskFor Win NT 3.5.1Select Main -> Control Panel -> Network -> Add Adapter -> Pick <Other> Requires disk from manufacturerFor Datafire BRI ISA or PC/IMAC:Pick sub-directory on diskette or hard drive for your bus/pc type.Example: A:\I386       If you have a Intel ISA or EISA PC	 A:\ALPHA      If you have a DEC Alpha PC	 A:\MIPS       If you have a MIPS PC	 A:\PPC        If you have a Power Point PCFor Datafire BRI PCI:Pick a:\ directory for diskette or hard drive directory downloadedfile was extracted to.Pick your Digi ISDN BRI adapter from list Keep following rest of install instructions.--------------------------------------------------------------------------------How do I know if the Digi ISDN BRI driver installed correctly?Check Event Viewer for any error messages. This will let you know if youhave a conflict or problem. For Datafire BRI ISA or PC/IMAC try anotherI/O or Memory addres (PC/IMAC only), no IRQ is used with this driver. Oruse Windows NT Diagnostics to check for hardware conflicts. If NT Diagsreports a conflict change to a non-conflicting address (Datafire BRI PCIadapter does not support changing it settings at this time, change theother 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--------------------------------------------------------------------------How do I run dginfbri.exe diag? (Datafire BRI ISA and PC/IMAC only)ISDN diag dginfbri.exe is a utility used to find out if there isproper communication to your ISDN provider. It will show which layersare passing or failing to determine where or if a problem exists. Digi ISDN Win NT diskette you must expand diag in the /{bus type} dir.Example for Intel bus: expand a:\i386\dginfbri.ex_ dginfbri.exeTesting of ISDN Layers 1-3:Layer 1 - This is a test to see if we are communicating to the physicallayer correctly. With the PC/IMAC, this may mean a proper connection tothe NT1 device. With the Datafire, is it properly seeing the ISDN line.Run diagnostic: dginfbri -a1Layer 1 passes if: Tx_Info_Pattern is INFO3 & Rx_Info_Pattern is INFO4                   You should then go to layer 2 and test with dginfbri.If Layer 1 fails : Did the Digi driver load correctly, 
                   where there any errors on bootup?		   Check cabling. Use cables that came with Digi or try		   another. Standard RJ11 phone cable will work. Unplug		   all cabling, wait few seconds, plugin, and retest.                   Check NT1. Any error lights. Try another NT1 if possible.                   If still having problems call Digi Tech Support.Layer 2 - This is a test to see if the requested TEI (terminal endpoint identifier) assignment from the switch was successful.The TEI is assigned dynamically, and if passes will assign a numberfrom 64-126. If you reboot or lose the ISDN connection to the switchthe TEI will be reassigned.Run diagnostic: dginfbri -a2Layer 2 passes if: State     = Tei Assigned                   Tei       = Number from 64-126	           Lap_State = Multiframe EstablishedIf you have 2 logical terminal you will see the above fields shown twice.The first time for the 1st logical terminal, then again for the 2nd one.Check both because you can have a problem with 1 B channel.You should then go to layer 3 and test with dginfbri.If layer 2 fails :A TEI of 127 (127 is reserverd for the switch) means we are requesting a TEIfrom the Switch and have not received that yet. Without the TEI, calls arenot possible.Causes for waiting TEI assignment:- Switch busy, needed resources- Connection not available yet (customer's switch programming not done yet)Unplug the RJ cables from wall, NT1, and Digi ISDN board, wait a fewseconds, replugin, and retest. If still having problems call Digi TechSupport.Layer 3 - This is a test to see if we are getting full service from theISDN switch. It will check to see if switch type entered during Digi driverconfiguration is correct. It will also check the SPIDs (typically, onlyused in the U.S.) against the values setup at the ISDN service provider.These values must match exactly. It is just like a password being approved.Run diagnostic: dginfbri -a3Layer 3 passes if:  State   = Active or Established, Awaiting Restart	          Service   = Full, Non Initializing, or Not DeterminedIf you have 2 logical terminal you will see the above fields shown twice.The first time for the 1st logical terminal, then again for the 2nd one.Check both because you can have a problem with 1 B channel.If layer 3 fails :Is the switch type entered during driver configuration correct?ISDN Switch TypesNI-1      - Pick if switch is National ISDN or the protocol is National ISDNNTI       - Pick if DMS100 running Functional pick NI-1 if running NationalAT&T      - Pick if AT&T running Custom pick NI-1 if running National ISDNNET3      - Standard international switch typeEuroISDN  - Identical to NET3VN4       - Identical to NET3   1TR6      - ITR6 (Germany)VN3       - VN3 (France)INS64     - INS64 (Japan)AUSTEL    - AustralianSIGNAPORE - SignaporeGENERIC   - Generic CCITT/ANSI switchAre the SPIDs (typically, only used in the North America) you entered duringDigi driver configuration correct? (no spaces, no dashes, just one longnumber)Otherwise, you must reconfirm this information with the ISDN serviceprovider. If you are still having problems call Digi Tech Support.--------------------------------------------------------------------------------What should I try next if Digi ISDN BRI  Win NT driver fails to load?* 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.

Any Digi Intl ISDN product with a S/T interfacewill require an extrenal NT1. Any Digi Intl ISDN product with a U interface will already have a builtin 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 andJapan, the telephone company provides the NT1, owns it, and offersend-users a S/T interface directly.  In North America, some ISDNequipment vendors offer devices which connect directly to the Uinterface (for example, the Datafire U).  If you have one of thesedevices, you don't need to buy a separate NT1.  The U interface can'tbe built in to the device when it's offered for sale in Europe orJapan. -------------------------------------------------------------------------------What are the three green LEDs on Datafire BRI ISA adapter for?D1 & D2 - Transmit and Receive lights for data across ISDN link D3            - Sync light (on or flashes intermitently)All lights will stay on until Digi ISDN driver loads-------------------------------------------------------------------------------How do I set up my Datafire BRI ISA adapter dip switches?SW1 dip switch sets I/O port addressOFF: switch away from board  ON: switch toward the board     switch                          switch------------------              ------------------addr    1    2    3    4        addr     1    2    3    4----   ---  ---  ---  ---       ----    ---  ---  ---  ---110    on   on   off  off       310     off  on   off  off140    on   off  on   off       340     off  off  on   off150    on   off  off  off       350     off  off  off  off300    off  on   on   off   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.

It is not yet working in Win NT 4.0 with any SP.----------------------------------------------------------------------------How can I use AT command strings with the Datafire?The Datafire BRI and PC/IMAC adapters are not ISDN modems. they aremore 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 forentering additional connection info. Under Dial Up Networking Phonebookproperties has an option for using a script. Modify default script todo the things done normally from terminal window. --------------------------------------------------------------------------Does Digi support CAPI 2.0?Digi is in the middle of developing a ISDN Windows CAPI 2.0 driverfor the Datafire BRI PCI adapter. Release date is not determined yet. Check with Digi Tech Support for further details. No CAPI 2.0 supportis planned for either PC/IMAC or Datafire BRI ISA adapters, because they do not have the necessary hardware support needed for CAPI. -------------------------------------------------------------------------------Can Win NT server route Digi ISDN traffic (internet) for local workstations?Yes, Microsoft has created Routing and Remote Access Service (formerlycode named Steelhead) for Windows NT server providing advanced routingand internetworking capabilities.Routing and Remote Access Service features include: * A unified service for routing and remote access that's integrated  with the operating system * A full set of routing protocols for IP and IPX* An easy intuitive remotable graphical user interface* APIs for third-party routing protocols, user interface, and management * Demand-dial routing * PPTP server-to-server for secure Virtual Private Networks * RADIUS client support Microsoft Routing and Remote Access Server can be found:http://www.microsoft.com/ntserver/info/Routing&RASdown.html Note: RRAS requires Win NT 4.0 with SP3 (Win NT 3.5.1 not supported)-------------------------------------------------------------------------------How can I do a ppp trace for debugging a connection problem?
