Check for any error messages during system bootup in Event Viewer. This will let you know if you have a conflict or problem. You could also check to see in ISDN ports show up in Dial Up Networking. Run Digi's ISDN line diagnostic for Win95, Win NT 3.5.1 or 4.0. The diag dginfbri.exe (previously called lineinf.exe) is used to test your connection to the ISDN provider. A text file (dginfbri.txt) explains how to run and what the output means. The diag dgtrcbri.exe (previously called trace.exe) is used to trace incoming or outgoing ISDN calls to see if they are connecting correctly. Or if disconnecting where the disconnect is coming from and the cause code why. A text file (dgtrcbri.txt) explains how to run and what the output means. The diags are universal and will work on Win95, Win NT 3.5.1, or Win NT 4.0. 4001119E.exe ISDN Win NT drv go to cd /tools/"bus type" and expand Example for Intel bus: expand a:\tools\i386\dginfbri.ex_ dginfbri.exe 4001425C.exe ISDN Win95 drv it is in the root directory / Diag readme files (dginfcri.txt & dgtrcbri.txt) can be found: Digi FTP (ftp.dgii.com) cd /support/appnotes/isdn -------------------------------------------------------------------------------- How do I remove/reinstall Digi ISDN driver?

Reboot system Reinstalling Digi ISDN Win95 driver (remove driver before reinstall) - Reload DUN 1.3 - Reload Digi ISDN Win95 driver - Reboot system -------------------------------------------------------------------------------- I'm having problems calling out, what are basic things to check? Treat ISDN call as if you were placing a normal phone call. Local call, just use seven digits. Example: 9886928 Long distance call, 1, area code, phone number. Example: 16129886928 Enter as one long number. No spaces, dashes, or commas New Long distance carrier-add prefix (MCI 1010222, Sprint 1010333, AT&T 1010288) Example: conn 101022216129886928 (This will call number using MCI) Centrex or PBX, you may need to dial a 9 for an outside line. Problems 64k call, try 56k. (Not all areas or the routes support 64k) Problem with 2 channel call, try one channel call Under Dial Up Networking -> Right click connection icon select properties Unchecked the box Use country code and area code (for all devices) Check Datafire termination (turn off if other ISDN devices on S0/ST bus) If all the above suggestions fail, call, fax, or email Digi Tech Support -------------------------------------------------------------------------------- Incoming/outgoing PPP calling problem to other ISDN products/Internet PPP calling problem under NT 4.0 Goto Dial Up Networking -> Phone Book Entry -> More -> Edit entry -> Server and try unchecking one or both of the boxes for Enable Software Compression and Enable PPP LCP Extensions PPP call problem under NT 3.5.1 Goto RAS phone book entry -> Network icon and uncheck Request LCP Extensions box Authentication method must be PAP. This is because Microsoft Win NT uses a proprietary version of CHAP. Most other vendors are supporting MD5 CHAP (i.e. Cisco, Ascend, etc.). MD5 CHAP encrypts the password and continues to issue challenges periodically, while Win95/Win NT CHAP though they encrypt the password, only sends challenge once. So unless the ISDN device you are using also supports Win NT CHAP you must use PAP. PPP protocol must be Sync PPP. Digi ISDN Win95 driver does not support V.110, V.120, X.75, or async modem connections. If using an ISDN terminal adapter you will need to select an async to sync PPP configuration. -------------------------------------------------------------------------------- How to make a 2 channel ISDN MP (Multilink PPP) call Requires Digi driver 4001425C.exe and Microsoft Dialup Networking 1.3 Goto My Computer -> Dial Up Networking 1. Make New Connection -> Select New 2. Pick name for computer you are dialing (Default: MyConnection) 3. Select a modem -> Pick your first Digi ISDN port 4. Enter first phone number for remote system you are calling 5. Select Finish 6. Now highlight MyConnection icon -> select File -> Properties 7. Under Set Additional Devices select Settings -> Use Additional Devices 8. Select Add -> Pick your second Digi ISDN port 9. Under Phone Number field enter second phone number for remote site If the remote side only has one phone number repeat for both Digi ports 10. Now try dialing the other vendor's ISDN product NOTE: Do not change Properties -> Configure -> Speed Preference -> 128k bonded this is only used for ISDN connections between two Digi ISDN systems ------------------------------------------------------------------------------- How do I place a 2 channel Digi ISDN to Digi ISDN call? Select Dial-Up Networking -> Make New Connection Select a modem: Digi ISDN port - i.e. Datafire -ISA4ST Line0 Select Configure -> Change Speed Preference to 128k Data(bonded) Select OK to accept, then Select Next to continue If remote side has 1 spid/1 phone number then enter area code (if long distance) and 7 digit number If remote side has 2 spids/2 phone numbers then enter 1st number then 2nd number separated by colon. All entered in Telephone Number field (area code blank). i.e 16125551212:16125551213 (Or try just 1st number for 128k call - works certain conditions) Select Next to continue, then select Finish to complete. Now try dialing the other Digi ISDN system ------------------------------------------------------------------------------- Does my Datafire (or PC/IMAC) require an NT1? 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 external 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. ------------------------------------------------------------------------------- What should I set my Datafire I/O port address to?
