WISDI, as it is provided, is a demo version. To make use of the full
capabilities of WISDI you have to register WISDI. The basic registration fee for
a single user license of WISDI is DM 70,. Please read the file
wisdi.txt for details.
As long as you have NOT
registered WISDI you may test WISDI for 30 days without a registration code. In
this case WISDI will stop forwarding data 15 min after startup.

WISDI is a (realmode) NDIS-2 Driver for IP-Routing or remote Ethernet
bridging over ISDN. WISDI communicates with the ISDN card using the Common ISDN
API 1.1 specification (a standard defined by German ISDN card manufacturers and
the German Telekom). Because of this, WISDI is completely hardware independent
and has successfully been tested with many active or passive ISDN cards.
WISDI
was developed for Internet access over ISDN from WfW 3.11 and MSTCP-32. WISDI
has successfully been tested with Win95. WISDI is also known to work with other
NDIS based TCP/IP packages for DOS and Windows, e.g. ChameleonNFS.
WISDI
can be used with standard DOS CAPI 1.1 software or VxD implemenations of the
CAPI 1.1 software. Using a VxD CAPI implementation, WISDI is available only
under Windows but it frees a lot of DOS memory otherwise used by the CAPI
software.
WISDI supports a large set of protocols for communication with
other vendors ISDN routers or servers. Among these protocols are: LAPB,
Frame-Relay, PPP, SLIP, Cisco-HDLC.
Some protocols conserve the protocol
type over point-to-point lines (multi-LAPB, Frame-Relay, Cisco-HDLC). These
protocols are able to handle multiprotocol routing. For PPP only IP support is
implemented at the network configuration layer.
WISDI can communicate at least with the following commercial systems:
Ascend
Routers, AVM MPR 3.0, Biodata ISDN Router, Cisco Routers, Conet S2M Router,
INS/CLS Banzai ISDN Router, netCS ISDN Router, RzK SLIP Bridge, SGI Indy ISDN
1.0, Spyder Routers, SunLink ISDN 1.0, SunLink ISDN 1.0.2.
WISDI was
written for use with ISDN BRI PC cards. WISDI was developed and implemented on a
Sedlbauer S0 card from Sedlbauer AG.
The current version of WISDI supports
two independent active connections at a time. Alternativly a connection can use
both B-channels for loadsharing. WISDI can be loaded more than once, if more
than two simultaneous connections to different sites are desired. Loadsharing
can be configured as static or dynamic (bandwidth on demand). Dynamic
loadsharing can be used concurrently with a second independent connection.
Loadsharing
over two channels is implemented using simple round robin scheduling, because IP
doesn't require the original packet sequence. This is completely hardware
independent and supported by many router systems. It works the same way as Cisco
implements loadsharing over to X.21 interfaces. With this kind of loadsharing it
is possible to get a performance of up to 13kBytes/s.
The latest version of WISDI is available on www.biochem.mpg.de/~heha or via ftp from:ftp.biochem.mpg.de in directory /pc/isdn.
WISDI's NDIS driver module is a NDIS-2 compliant MAC driver. Multiple protocol modules can bind to WISDI. To include WISDI in your NDIS configuration:
[ISDI]
Drivername=ISDI.DOS
4. The protocol module you want to bind to ISDI should reference the ISDI
MAC driver section with a "BINDINGS" entry of the form:
BINDINGS=ISDI
5. Check also that the device PROTMAN.DOS is loaded in CONFIG.SYS.
6. Reboot your system.
7. Start WISDI.EXE under Windows
Select "Add adapter"
Select "OEM provided adapter"
in directory C:\WISDI
Add the TCP/IP Protocol and remove all other
protocols from the adapter. The MS-TCP32 software is not part of the standard
WfW distribution, but it is freely available from Microsoft.
Configure the
TCP/IP parameters.
4. After rebooting start a DOS-shell inside Windows and run "IPCONFIG". It should display your TCP/IP parameters.
5. Start WISDI.EXE under Windows
An example of a user installation you will find here.
Installation in Windows95 is equivalent to installation in WfW.
A detailed example you will find here.
The NETBIOS based WfW 3.11 peer-to-peer network can operate on different transport protocols (NETBEUI, DECnet, TCP/IP). After installing MS-TCP32, WfW and Win95 send broadcast messages also over TCP/IP to look-up other nodes. If you don't disable broadcast's in WISDI, this will trigger an ISDN connection every time a broadcast packet is sent. You can disable broadcasts in WISDI by either specifying a dedicated ip-address (not 0.0.0.0) for the ISDN peer or enabling the k-option for this link. Using the k-option, broadcasts will not keep the line up and will not trigger a new connection, but the peer-to-peer network capabilities are available over ISDN after opening a connection.
Section name: ISDI
Driver name: ISDI
File: C:\WISDI\ISDI.DOS
7. Continue with configuration from "Custom".
8. Custom creates a PROTOCOL.INI file.
9. Reboot and check your configuration.
10.Start WISDI under Windows
1.WISDI displays the state of an ISDN connection on its status page and on
the icon:
_ = free,
D = D-channel up,
C = B-channel requested,
B = B-channel up,
A = active, ISDN connection up,
additional
information for PPP:
L = LCP configuration up,
I = PAP/CHAP
configuration up, IPCP configuration started,
P = PPP connection up
2.Menus
File
Setup starts the Notepad with your configuration
file. You have to restart the program to load a modified configuration file into
memory.
Register prompts for the licence key and your name,
company. The personal information in the name field must be at least 12
characters long. To activate a licence key you have to restart the program.
After restart check the info menu to know if the licence information was
accepted.
Save Buffer saves the screen contents to a file. If the
file exists the contents is appended to the file.
Exit terminates
the program
View
Status selects the status page for display.
Configuration
displays the active configuration.
Log dislays a connnection and
optionally trace log.
Trace
Use the trace only for debugging NOT in normal operation.
CAPI Messages logs all messages exchanged with the CAPI software
(except data transfer)
PPP Setup allows to trace the setup of a
PPP connection. PPP data packets are not logged.
Application Interface
logs information related to the upper layer interface (packet or NDIS)
Control
Connect manually connect to a IP destination.
In case of PPP with authentication the program prompts for authentication
information. The initial setting of the repeated dial request option depends on
the Preferences configuration.
Disconnect disconnects all active
ISDN connections or terminates a repeated dial reuqest.
Reset
Statitstics resets all counters.
AutoDial enable or disabes the
auto dial feature.
Preferences defines the initial program
settings. Selectable are the language of menus and messages, the cost per unit
and currency value and the initial setting of the repeated dial option. All
settings are saved in a file ISDNMON.INI.
The program beeps on connect and
disconnect. If the "Play Sound" option is checked, the program will
play the .WAV files assigned to "ISDNup" on connect and "ISDNdown"
on disconnect.
The "Save Log" option will automatically save the log pages on program exit (only for registered users).
If "Show Up Time" is selected the icon or taskbar title will show the connect time.
Help
Info displays program version information.
WISDI.EXE can be started with the following optional command line arguments:
You can enter arguments for a Windows program via the Properties entry of the Programmanager.
Flags the argument is currently ignored for compatibility with
previous versions.
ConfigFile specifies the name of the WISDI
configuration file. If the name is not given, it defaults to "WISDI.INI".
The configuration file is a readable text file. How to set up a configuration
file and a complete reference of all configuration options is described in the
configuration guide.
WISDI works as an ethernet type NDIS-2 Driver. The ethernet address of WISDI
is defined as: 00-00-0xFB-0xAA-00-01. (Thanks to RzK, Asbach, Germany for using
numbers from their official 00-00-0xFB range.)
The ethernet address of
WISDI is settable by software via the NDIS interface. This way the ethernet
address can be changed to any other desired value.
Changing the ethernet
address may be required when connecting two WISDI's with direct applications
using an ethernet bridging protocol.
The latest version of WISDI is available on www.biochem.mpg.de/~heha or via ftp from:ftp.biochem.mpg.de in directory /pc/isdn.
