J1-J2 control IDP1, J3-J4 for IDP2, J5-J6 for IDP3, J7-J8 for IDP4-------------------------------------------------------------------------------Does my Datafire (or PC/IMAC) require an NT1?An NT1 (network terminator 1) is a device which provides an interfacebetween the two-wire twisted pairs used by telephone companies intheir ISDN Basic Rate (BRI) network and an end-user's four-wireterminal equipment. 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 or Japan. -------------------------------------------------------------------------------How do I know if the driver installed correctly?First, check for any error messages. This will let you know if you havea conflict or problem. If error, try another I/O port or memory address(only with PC/IMAC).Second, check Remote Access phone book. Do you see Pcimacisdn1 or Pcimacisn2port under Port selection. If he port if there the driver has probably loaded correctly. (Note: Pcimacisdn is port name for both Datafire or PC/IMACboards).Third, run lineinf.exe diagnostics. These can be found on you driverdiskette.Next run lineinf from DOS prompt with -v option. Example: lineinf -vThis is a Pass/Fail diags. It will either show GO all three layers,with indicates everything should be ok and that we can now try to placeor receive a call. If any layer is stopped, this is a problem and youshould call Digi Tech Support.-------------------------------------------------------------------------------How do I test my ISDN line?Call Digi's ISDN Win NT 4.0 test system.Phone number for 1st B channel: 612-988-6946 (do not use dashes when calling)Phone number for 2nd B channel: 612-988-8320 (do not use dashes when calling)Login: guest Password: guest Domain: Leave Blank-------------------------------------------------------------------------------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 propertiesUnchecked 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 -------------------------------------------------------------------------------Does WFW support ISDN dial in? Yes, by using Microsoft's wfwptp.exe file this will allow one of the systemto allow incoming calls. Contact Microosft's FTP or BBS site for file.-------------------------------------------------------------------------------How do I place a 2 channel Digi to Digi ISDN call?Select following icons Remote Access Service --> Remote Access --> Add RAS phone book entryYou need to separate the remote phone numbers with a colon (:).See examples below for more information If separate phone number for each B channel at remote site Phone Number: 5551212:5551213If 1 phone number for both B channels at remote site:Phone Number: 5551212:5551212Then select ISDN icon in RAS phone book entry and change numberof channels from 1 to 2.-------------------------------------------------------------------------------How can I make a connection to another ISDN vendor's equipment/Internet.When connecting Digi ISDN to another vendor's product you must use syncPPP under TCP/IP. Since standard RAS only supports NetBEUI, not theneeded TCP/IP you can't use that. The easliest and cheatest way to handlethis would be to update to Win95. Win95 has the ISDN support for TCP/IPas well as built in TCP/IP support. Or you can do is use a TCP/IP packagewith WinISDN support like Netmanages's Chameleon or FTP Software's OnNet.Since our ISDN WFW driver has WinISDN support this will give you the neededTCP/IP PPP support needed to connect to another ISDN vendor's product orthe internet. But what -------------------------------------------------------------------------------Is the Datafire a ISDN modem?The Datafire board is NOT an ISDN modem, it is more like anISDN ethernet board. And since it does not emulate a modemyou can not do AT commands to it, so those applications arenot supported.-------------------------------------------------------------------------------
