WINDOWS 95 ISDN FUNCTIONALITY
=============================

This second beta release includes the necessary support in 
Microsoft(R)  Windows(R) for remote access over ISDN. Although 
ISDN on a PC is possible today, special ISDN programs are required
to take advantage of it. The addition of support in the operating 
system for ISDN dramatically broadens the range of programs 
available. Instead of requiring specialized programs that work 
only with ISDN, users will be able to run any networked 
Windows-based program over ISDN. 

This release provides all the support for an application to 
initiate remote connections exactly as would be done using a 
modem. This release works with drivers for some specific ISDN 
adapters; however, many other drivers are in progress and will be 
available soon. Contact your ISDN hardware vendor for information 
on when additional drivers will be available.

This release of ISDN in Windows can only be used for data 
transmission. Microsoft does not currently support voice or other 
types of ISDN access. Both Voice support and Multilink capability 
are planned for an upcoming release.

CONNECTING WITH YOUR ISDN ADAPTER
=================================

After completing the adapter installation and restarting your 
computer without any error messages, you are ready to create a 
Dial-Up Networking connection. Make sure you have installed the 
cables provided with your adapter, that the line indicators are 
good on the NT-1 (if required), and that the line is active. 
Dial-up Networking should be already installed on your machine. 
To create a connection: 

   * Start Dial-Up Networking by selecting 
     Start|Programs|Accessories|Dial-Up Networking from the 
     Windows 95 start menu.

   * If the Make New Connection wizard does not automatically 
     start, double-click the Make New Connection icon.

   * On the first screen, fill in the name of your new Connection.
     In the Select a modem list, choose your ISDN adapter. 
     Click Next.

   * Fill in the area code, phone number, and country code for 
     the computer you want to call. Click next.

   * Click Finish.  

   * You can now make a connection over ISDN by simply 
     double-clicking the new icon you just created, entering 
     your account name and password, and clicking Connect.


CHANGING SETTINGS FOR YOUR ISDN ADAPTER
=======================================

To change configuration settings for your ISDN adapter after you 
have initially configured the adapter according to these 
instructions, click with the right mouse button on the Dial-Up 
Networking icon you created above, click Properties, then click 
Configure, then click Advanced. You can then change your 
configuration settings in the Line and Connection tabs. 

To configure networking protocols or unusual TCP/IP settings, 
right-click on the Dial-Up Networking Connectoid, click 
Properties, then Server Type, then TCP/IP Settings.


KNOWN PROBLEMS
==============

Shadowing in Gateway machines with an AMI BIOS must be turned off
-----------------------------------------------------------------
If an AMI BIOS in Gateway machines has shadowing turned on for 
the ranges of memory that the Digi PCIMAC board uses for its 
shared memory, the PCIMAC board will fail when it attempts to 
access the shadowed memory.  Turning off shadowing fixes the 
problem.

Cannot Use DOS Net Commands With Eicon Adapters
-----------------------------------------------
If you have made a connection with an Eicon Adapter and attempt 
to access the server you are connected to with either the "net 
view" or "net use" DOS commands (net view \\server or net use * 
\\server\share), you will get an error.

Suspend mode on some laptops may cause error
--------------------------------------------
If you are using a PCMCIA adapter and close the lid of your 
laptop or press suspend, you may get an error. If this happens, 
restart the machine.

TCP, IPX or NetBEUI protocols are needed 
----------------------------------------
Although NDISWAN shows up as a protocol, you still need to have 
TCP/IP, IPX/SPX, or NetNEUI installed.

Exchange Over ISDN in Connected Mode May Hang On Disconnect
----------------------------------------------------------
If you are running Exchange over ISDN in connected mode rather 
than using the remote mail feature, your computer may hang when 
you disconnect, even if you close Exchange before disconnecting. 
This is because MAPI stays in memory for 30 seconds after 
Exchange is closed. To avoid this problem, do not disconnect 
until 30 seconds after exiting Exchange.

USR Driver Can Not Be Disabled
------------------------------
Disabling the USR driver by using Device Manager results in 
system failure.

Configuration of Bonding (128K) in Digi driver is not automatic
---------------------------------------------------------------
To configure bonding with the Digi adapter, you must configure 
only your data SPID(s) during the configuration process.

Should not use USR Turbo PPP with some servers
----------------------------------------------
If Turbo PPP is enabled in the USR driver, your Windows 95 client 
might not work well with certain kinds of PPP servers. If you 
have difficulty interoperating with a PPP server, disable Turbo 
PPP, and then try again.

Trap 14 During Installation of USR adapter
------------------------------------------
An error may occur on some machines during installation of the 
USR adapter when you are in the process of restarting your 
machine. Resetting your computer allows installation to 
continue normally.

Reconnection May Fail After First Connection With Digi PCIMAC
-------------------------------------------------------------
If a connection to MSN or the Internet is established, broken, 
than a reconnection attempted, the reconnection attempt may fail 
with an error "cannot establish a compatible protocol.", or you 
may have to redial multiple times to re-establish the connection. 
This happens only when both SPIDs were entered during 
configuration. Removing the second SPID should solve the problem 
(see the section CHANGING SETTINGS FOR YOUR ISDN ADAPTER in this 
file for information on how to do this). Restarting the computer 
also allows a connection to be made again.
