ABOUT ISDN 1.1 ACCELERATOR PACK
===============================
ISDN 1.1 adds Wide Area Networking capability to
Windows 95, enabling MSN and Internet access at speeds
up to 128 kbps when using supported ISDN adapter hardware.
ISDN 1.1 is an upgrade to ISDN 1.0 and increases user speed
from single channel 64 kbps up to dual channel 128 kbps
performance.
Additional information about ISDN is available from
Microsoft's "Get ISDN" web page at:
http://www.microsoft.com/windows/getisdn/
The MSISDN11.EXE file is a self installing archive
for the new software components of ISDN 1.1
Accelerator Pack. After MSISDN11.EXE runs all the
new system components will be in their proper install
directories on the system, ready for installation of
the ISDN adapter driver.
ISDN 1.1 ACCELERATOR PACK FUNCTIONALITY
=======================================
The ISDN 1.1 Accelerator Pack includes the support
necessary for making remote access connections
over an ISDN line. Although it is already possible to use
ISDN on a PC, special ISDN programs are required to
take advantage of ISDN. The addition to the operating
system of support for ISDN dramatically broadens the
range of programs available. Instead of requiring
specialized programs that work only with ISDN, users can
run any networked Windows-based program over ISDN.
This release provides all the support needed for a program to
initiate remote connections exactly as would be done by using a
modem. This release works with drivers for some specific ISDN
adapters; in addition, many other drivers are being developed and
will be available soon. For information about when additional
drivers will be available, contact your ISDN hardware vendor.
This release can be used only for data transmission. Microsoft
does not currently support voice or other types of ISDN access.
INSTALLING AND CONFIGURING ISDN 1.1 ACCELERATOR PACK
====================================================
TO INSTALL, REFER TO THE HARDWARE MANUFACTURER'S INSTALL.TXT FILE,
OR RUN THE HARDWARE MANUFACTURER'S SETUP PROGRAM.
Before you install, make sure you have the following:
1. A supported ISDN adapter.
2. An ISDN line installed.
3. Your switch type, SPIDs, and phone numbers from your telephone
company. If you do not have this information, get it from your
telephone company before continuing.
4. ISDN 1.1 Accelerator Pack software and a driver for your
specific hardware.
5. A PC running the released version of Microsoft® Windows® 95.
6. Dial-Up Networking installed. If you do not have it installed,
you can install it by using Add/Remove Programs in the Control
Panel as follows:
* In Control Panel, double-click the Add/Remove Programs icon.
* Click the Windows Setup tab.
* Click the Communications check box, and then click Details.
* Click the Dial-Up Networking checkbox, and then click OK.
* To finish installing Dial-up Networking, click OK. Note that
you may be asked to insert your Windows 95 floppy disks or CD.
MAKING A CONNECTION WITH YOUR ISDN ADAPTER
==========================================
After you have successfully installed the adapter and restarted
your computer without any error messages, you are ready to
create a Dial-Up Networking ISDN connection. Make sure that you
have installed the cables provided with your adapter, that the
line indicators are good on the NT-1 (if an NT-1 is required with
your adapter), and that the line is active. Dial-up Networking
should already be installed on your computer.
To create a connection:
* Start Dial-Up Networking as follows:
* Click Start, and then point to Programs.
* Point to Accessories, and then click Dial-Up Networking.
* 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, and then click Next.
* Fill in the area code, phone number, and country code for
the computer you want to call, and then click Next.
* Click Finish.
* You can now make a connection over your ISDN line
by double-clicking the icon you just created,
entering your account name and password,
and then clicking Connect.
CHANGING SETTINGS FOR YOUR ISDN ADAPTER
=======================================
After you have successfully configured your ISDN adapter, you may
want to change your configuration settings. To change settings,
carry out the following procedure:
* Right-click any Dial-Up Networking ISDN connection icon,
such as the one created in the previous procedure.
* Click Properties, and then click Configure.
* Click Advanced and then change the configuration settings.
To configure networking protocols or unusual TCP/IP settings,
carry out the following procedure:
* Right-click any Dial-Up Networking connection icon, such as
the one created in the previous procedure.
* Click Properties, click the Server Type button, and then
click TCP/IP Settings.
USING MULTILINK
===============
Microsoft ISDN 1.1 includes updates to Microsoft Windows® 95
Dial-Up-Networking to support the combining of two 64 kbps
data channels into the equivalent of a single 128 kbps line.
The technique of combining multiple lines together into a single
dial up connection is known by several names including "multilink",
"dual channel access", and the more technical
"MLPPP" or "PPP Multilink."
Multilink is available when you have more than one dial
up device in your system such as two "B" channels of an ISDN
connection. If you have only one device configured, then you
will not be able to use multilink. Multilink depends upon the
capabilities of the service or corporate network that you are
dialing. To use multilink, the answering Internet service
provider, online service or corporate LAN must provide multilink
capabilities.
Configuring Multilink
---------------------
To configure multilink support in Windows 95, double click
on the My Computer icon on your Windows 95 Desktop, then double
click on the Dial Up Networking (DUN) folder. The DUN folder
displays an icon labelled "Make New Connection", plus icons
for each of the connections that you have already created.
If you have not yet created a connection, double click
on "Make New Connection" to define a connection to the
dial up service you wish to use.
When you have created your connection, or if the connection you
wish to use for multilink access already exists in the folder,
use the mouse to right click on the connection icon. Choose the
"Properties" option. This displays a dialog box with several
category tabs at the top. At the bottom of the "General"
properties page, you will see a section labelled "Set Additional
Devices". Within this section, click on the "Settings" button to
display the "Set Additional Devices" dialog.
On the "Set Additional Devices" dialog, click on the "Use
Additional Devices" radio button. Use this dialog to specify
the devices to be bundled together to form the "multilink"
connection.
Use the "Add", "Remove", and "Edit" buttons to change the
list of additional devices. You may enter a different phone
number for each device, and both phone numbers will be stored.
If you subsequently change the phone number for the connection
icon, the phone numbers associated with additional devices on
this page will not change.
Multilink Operation
-------------------
After your additional devices are configured using the
procedure outlined in the previous section, you are ready
to dial your multilink connection. When you dial the connection,
Dial Up Networking dials the primary number of the primary device
specified for the connection. Once the first connection is
established, Dial Up Networking will then dial the other devices
specified in the Additional Devices list.
Once the connections are established, you can view status
information about the link by double clicking on the
"communicating computers" icon displayed in the taskbar, or you
may disconnect the connection.
The status information includes the number of bytes sent and
received, the network protocols negotiated for use on the
connection, and a list box showing each of the additional
devices. As you highlight a device in the list box, a "Suspend"
or "Resume" button is displayed. If a Suspend button is
displayed, then the device is now in use and "bundled" into the
multilink connection. Clicking on the "Suspend" button
disconnects that line and removes the line from the bundled
connections.
If the "Resume" button is displayed, then click on "Resume" to
dial that connection and add that line to the bundle. You may
suspend and resume individual links without dropping the
connection.
KNOWN PROBLEMS AND WORKAROUNDS
==============================
1. The ISDN 1.1 Accelerator Pack adds Windows 95
support for ISDN Wide Area Networking. To use
ISDN 1.1 you must have a supported ISDN 1.1
hardware adapter and an appropriate ISDN driver
provided by the ISDN adapter manufacturer.
2. You must install the ISDN 1.1 Accelerator
Pack before installing ISDN drivers. If the
Accelerator Pack is not installed and you attempt
to install a driver, you'll receive a dialog
saying that NDISWAN needs to be installed.
This is a problem with PC Cards because
Windows 95 will continually autodetect the device
and attempt to install the drivers, but fail
because NDISWAN hasn't been installed. To
correct this problem, remove the PC Card and
install ISDN 1.1. Then reinsert the card.
3. If you insert a PnP ISDN adapter (including
PC Card adapters) before the ISDN 1.1 package
has been installed, the system does not
know what to do with the card. The drivers
refer to software which has not been
installed, so usually, the card ends
up as an "Unknown Device" in the
Configuration Manager list.
To correct this problem:
1. Install the ISDN 1.1 Accelerator Pack,
and then restart your computer.
2. Double-click the System icon in Control Panel,
and then click the Device Manager tab.
3. Select the Unknown Device, and then click Remove.
4. When upgrading from ISDN 1.0 to ISDN 1.1, it is
not always necessary to reinstall the drivers. If you
do install a driver as part of upgrading from ISDN 1.0
to 1.1, it does not make any difference which you
install first, ISDN 1.1 or the driver. It is important
to have the newest possible driver installed
or a driver that works with ISDN 1.1. If an older
driver is used with ISDN 1.1, you will see the
following dialog when a connection is attempted.
"The Microsoft Dial-Up Adapter is not installed
or not responding properly. In the Network section
of control panel, remove the driver and then add
it again."
If this occurs, a driver that supports ISDN 1.1 must
be installed and the old one removed.
5. In some cases (such as with the Eicon adapter), you
will have reconfigure your Dial Up Connections to reflect
the proper device name.
6. The Windows 95 Dial In Server feature (available
in the Windows 95 Plus! Pack) does not support multilink
connections.
7. MSN now supports dual channel ISDN access.
Due to the way that incoming calls are routed
into MSN, it is possible that a dual channel ISDN
call will be split improperly when answered by
MSN. When this occurs, you will be unable to complete
your call. The solution is to disconnect and call again.
8. MSN's ISDN dual channel access requires that you
use the latest MSN software. In some cases,
problems that affect ISDN access can occur
when upgrading from older MSN software to newer
MSN software. These problems appear to be related
to the ISDN adapter and ISDN driver software in use.
The symptoms you will see are that you can select ISDN
access numbers but you receive a message saying
"error 87 in dial up networking".
To work around this problem, you should open the
Dial Up Networking folder (double click on
"My Computer" and then double click on
the Dial Up Networking folder). Choose 'Make New
Connection' and create a connection named "The
Microsoft Network". Enter your MSN access number.
Open the 'Connection Settings' dialog, and select
'Connect using another dial-up Internet access
provider.' Close the dialog and then use this
connection icon to access MSN.
9. There is a problem with the Eicon Diva ISA ISDN adapter
driver that prevents its use with MSN. In the
'Connection Settings' dialog, if the user sets the
'Connect Using' combo box to the Eicon ISDN device, the
'Access Numbers' and 'OK' buttons cease to function. You
should press the 'Cancel' button to exit the dialog.
This problem is due to the Eicon driver not supporting
a feature used by MSN.
To work around this problem, open the 'Connection Settings'
dialog, and select 'Connect using another dial-up
Internet access provider.' Click 'OK' to close the dialog
box.
Next, open the Dial-Up Networking folder and double click
on 'Make New Connection' to create a dial up networking
connection. Name the new connection "The Microsoft Network"
and enter the MSN access number that you would
have used within MSN.
Once the dial up networking icon has been created inside
the Dial Up Networking folder, right click on the icon and
select 'Properties'. With the 'Properties' dialog open,
select the 'Server Types' tab. Make sure that only the
following checkboxes are checked:
-'Enable software compression'
-'TCP/IP'.
All other options should be unchecked. Close the property
dialog and then double click on the icon you just created.
For your username, enter 'MSN/' plus your MSN username.
So if your username was 'JoeSmith' use 'MSN/JoeSmith'.
For your password, use your MSN password. Once you've
connected, switch back to MSN. Enter your username and
password again here. Click 'Connect' and you should
connect to MSN.
