What You Need

---

Computer Requirements

• 386+ compatible computer with ISA or EISA slot (33 MHz or faster recommended) for the low profile, half-length Card.
• EGA, VGA, or better, graphics monitor
• Mouse that is functional in Windows.
• Windows 3.1+, WinOS/2 2.1+, Win95, or NT
• Card takes 4K RAM in memory (switch selectable) and one interrupt (jumper selectable).

Other Software/Hardware Requirements

• Use a WinISDN or RAS/WAN-based HDLC TCP/IP stack from various software vendors, such as NetManage, FTP, Shiva, or Microsoft.
• Standard analog telephone handset or headset for voice cards.

The ISDN Telephone Requirements

• ISDN Line from your telephone company’s National ISDN-1 (NI-1), or AT&T 5ESS (5E6+), or Northern Telecom DMS100 (BCS34+), or Siemens EWSD (APS 10+) switch.
• 2B+D Basic Rate Interface with voice and data.
• If not purchasing the “Plus” product, you will need a Network Termination unit (NT1) with S/T interface. Order this from ISDN*tek, your phone company, service provider, telephone equipment supplier, or computer integrator.

How to Order your ISDN Line

Your local phone company may use switching equipment from AT&T (5ESS), Northern Telecom (DMS100), or Siemens ( EWSD). The phone company will configure your line based on their central office (CO) equipment as well as your terminal equipment (TE). Your CyberSpace card (TE) will automatically work with all of that equipment without any special configuration on your part. However, it is important to provide the phone company with the template on the next page.

Pacific Bell has extensively tested the CyberSpace cards and has come up with a template for their engineers to use in programming ISDN lines for the CyberSpace products. Other telephone companies may also find this line translation information helpful. We are reprinting that table for the convenience of your telephone company service representative. When you call your telephone company’s ISDN order department, give them the information provided in the template.

When your line is installed, the phone company will provide you with your telephone (Directory) number and your Service Profile Indentifier (SPID). You may receive one set of numbers or two sets, depending on your telephone company’s equipment. Record this information, as you will need it later for hardware and software setups of any ISDN equipment that you install.

Other Ordering Options (not required)

This section is purely optional. In addition to using the previous Line Configuration Template, you may also choose your own line configuration based on your current needs, economics, or future requirements, since each telephone company may bill differently for each group of options. The following capability sets are compatible with ISDN*tek equipment and may be viewed as alternative options for ordering your line. ISDN*tek recommends choice “M” for the most flexibility, which is the default selection for the previous Line Configuration Template.

Install Software

---

Setup Program

BEFORE installing the Networking in NT4.0, run the isdntek.exe that shipped with your CyberSpace board.

The ISDNTEST install/test program provides configuration assistance for your ISDN*tek CyberSpace Card. There are many systems that must work together to provide you with a seamless interface to CyberSpace, and this card sits squarely in the middle. For this reason, it is important to check each interface at every step of the installation.

System Requirements for Install/Test Program:

• ISDN*tek’s CyberSpace Card. PC-386 or higher with 640K memory.
• EGA, or better, graphics monitor.
• Hard Disk.
• Mouse.
• Windows 3.1 or greater, Win95, Windows NT, or Win-OS/2.

Note: This installation and test software may have been distributed in compressed format.

IMPORTANT: When running the installation program ISDNTEK.EXE, be sure to choose the DLL installation option. The default VxD driver installation WILL NOT WORK in Windows NT.

From the Windows Program Manager, select Run, and enter A:ISDNTEK.EXE to auto install from the distribution diskette. The following programs and files will be decompressed and copied to the directory that you specify in the installation procedure.

IMPORTANT: Two files required by some applications are not included on the installation diskette. They will be created when you run the ISDNtest program:

ISDN.INI Initialization File
WINISDN.DLL Hardware Driver

The ISDNtek.exe self-extraction program writes all files to a temporary location on disk. A setup program is automatically invoked to allow you to choose a destination subdirectory and to install or un-install the VxD or DLL drivers. The default VxD installation is recommended for all but NT and OS/2 users.

The 32-bit VxD-based ISDN Driver (vwinisdn.386) is the default at installation, and in addition to allowing simultaneous use of Dial Up Networking and WinISDN-based applications, it is ShivaPPP approved for communicating with the LanRover on a Novell network from Win 3.1x and Windows for Workgroups (WFW) machines.

An NT subdirectory is created containing Drivers for NT machines. ISdn*tek currently supports Windows NT version 4.0.

After installing the files, reboot Windows, select the Test ISDN Hardware icon or run the ISDNtest.exe program to configure and test your ISDN hardware.

Installing Your CyberSpace Card

CyberSpace Card Hardware Settings

SW1, the 8-position DIP Switch, sets the segment address. The boards are factory set as shown, setting the memory segment to D000h. If your system's resources for the factory settings are already allocated to something else you will need to change the switch settings. See below for more details.

The interrupt is set using the IRQ jumpers at the bottom of the board. The default setting is IRQ10. Change the jumper if you need to allocate the IRQ to a different setting -- that is if your system resources for IRQ 10 are already in use (See NT Diagnostics in Administrative Tools for available resources). Typical IRQ assignments are listed below. Make a note of your IRQ settings, you may need to enter in this information later.

Four Common Memory Address Switch Settings

The full range of Memory Addresses from 0000 to FFFF are available to the board through switch settings. Four are shown:

Change the switch settings if you need to -- that is if your system's memory resources for the factory default settings are already in use (for available resources, see NT Diagnostics in Administrative Tools). Make a note of these settings, you may need to enter in this information later.

Typical IRQ Assignments

Below is a table of typical IRQ assignments. Check for possible conflicts before assigning an IRQ to your CyberSpace Card.

• IRQ0 System Timer
• IRQ1 Keyboard
• IRQ2 System Interrupt
• IRQ3 Com2
• IRQ4 Com1
• IRQ5 LPT2 or Spare Slot
• IRQ6 Diskette Drive
• IRQ7 LPT
• IRQ8 System Real-time Clock
• IRQ9 Spare Slot
• IRQ10 Spare Slot
• IRQ11 Spare Slot
• IRQ12 Mouse
• IRQ13 Math Coprocessor
• IRQ14 Fixed Disk controller
• IRQ15 Spare Slot

S/T Termination Resistors

The CyberSpace boards with an S/T-interface provide100 ohm termination resistors that are preset with jumpers on W3 and W4 near the phone jack. Removing the jumpers will remove the resistors from the circuit. These jumpers will generally remain as set on the board unless additional equipment is on the same phone line. The CyberSpace+Plus boards, with a U-interface, do not use termination resistors.

The PC

Turn off all Power to machine and unplug from wall power. Remove PC cover to expose the ISA-bus. Carefully install the CyberSpace Card in any empty PC-AT slot. Plug Telephone (8-wire) cable into the RJ-45 socket on the board if using the CyberSpace Card; or plug standard 4-wire cable into the RJ-11 socket on the card if using the CyberSpace+Plus Card with onboard NT1. Plug a Handset/Headset into the smaller jack on the CyberSpace Card if your card includes a voice feature. Replace cover on PC.

Power up Systems

Plug PC into power source. Turn on PC. It should boot up normally. Plug the loose end of the telephone cable into the S/T socket of your NT1 (or directly into the wall jack if using the CyberSpace+Plus Card with onboard NT1).

Handset/Headset for Voice

For voice applications, the Commuter Card has a standard 4-wire jack for a handset or headset. Generally, the handset from your existing analog phone should work just fine. Headsets are available in a wide variety of styles, and most of them include a volume control for comfort and aural safety. Not all headsets will work with the CyberSpace Commuter card, so ISDN*tek will be publishing a list of compatible types on it’s homepage at http://www.isdntek.com.

The first phase of network installation is now complete.

Click Next.

Click on Finish, but DO NOT RESTART the system at this time. You have completed the data entry and NT now copies some files from disk or CD and launches the Remote Access Services and Adapter installation process.

RAS Installs ISDN*tek Adapter

IRQ 10 and Memory Base 0xD0000 are the physical default settings on the board and also software defaults, set in the oemsetnt.inf file.

Enter your SPID fields. If necessary, change default IRQ and Memory settings here.

0The bus settings shown here are correct for almost all users.

Click OK.


The next screen (not shown) allows you to add the ISDN lines to RAS. You must choose at least one line, ISDN1 or ISDN2, and select Add. After adding one or both lines, continue to the next screen which will display the ISDN lines that have been added to RAS.

After adding ISDN lines, the RAS screen will appear as seen here:

Now select ISDN1 and click Configure.

Change the default ISDN1 line configuration to Dial Out as well as Receive calls. ISDN2 should be left in the default Dial Out only.

Click OK to return to the previous screen.

Then click Continue.

Click on Next until the installation finishes.
