        WAN Services for Windows NT Version 3 Release 2


Introduction
===============================================================

These Release Notes apply to the Eicon Technology WAN Services
for Windows NT V3R2 product; they supersede any corresponding
information in the WAN Services for Windows NT System Guide
(206-100-02).




General
===============================================================

This section contains general information on WAN Services for
Windows NT.


Long File Names 
---------------

The WAN Services Configuration program does not support long 
file names at this time. It is restricted to the DOS
convention of 8.3 (xxxxxxxx.xxx)file and directory names.
Therefore when installing the WAN Services for Windows NT
product, make sure you follow the 8.3 naming convention for
the install directory, or the WAN Services Configuration
program will fail to function correctly. 


Multi-Processor Support
-----------------------

Multi-Processor support for both the Intel and DEC Alpha
platforms is not supported at this time. Please contact Eicon
Technology representative for information on the availability
of Multi-Processor support.


PPP Packet Size 
---------------

When using a PPP connection, there is no PPP packet size
negotiation. Therefore you must not change the default value of
the PPP packet size of 1500. This parameter is found under the
PPP configuration panel in the WAN Services Configuration
program. 


X.25 CCITT Recommendation 1988
------------------------------

At this time, the XPAD/RAS combination is the only function of
WAN Services which supportsX.25 CCITT Recommendation 1988. All
other functions of WAN Services for Windows support X.25 CCITT
Recommendation 1984. 




Uninstalling WAN Services
===============================================================

This section contains information relevant to removing the WAN
Services for Windows NT software from your PC. If you have any
problems uninstalling WAN Services, please contact your Eicon
Technology Representative.


Disabling IP Routing Services 
-----------------------------

If you try to uninstall WAN Services for Windows NT with Eicon
IP Routing Services installed, the procedure will fail to
function properly. You must disable the IP Routing Services
before uninstalling WAN Services. 

To successfully uninstall WAN Services follow these steps:

1  From Control Panel, start the Services applet.

2  Highlight the EICONNDISROUTER entry, and click the Startup
   button.

3  From the Startup Method dialog box, choose Disable, then
   click OK.

4  Highlight the EICONRIP entry, click the Startup button
   and repeat Step 3.

5  From Control Panel, start the Drivers applet.

6  Highlight the ECNDIS entry, click the Startup button, and
   repeat Step 3.

7  Reboot the PC, then follow the uninstall procedure found in
   the section "Uninstalling WAN Services", in Chapter 2 of the
   WAN Services for Windows NT System Guide.


Removing the WAN Services Directory
-----------------------------------

When uninstalling the WAN Services for Windows NT, the WAN
Services directory (default is C:\EICON) is automatically
removed. This action may fail for the following reasons:

1  All Eicon services were not stopped prior to removal of
   WAN Services.

2  Extra files were manually copied or created in the WAN
   Services directory, such as a log file or TRACE file.

If any of the preceding conditions prevented the WAN Services
directory from being deleted, you must manually delete the
directory. 



WAN Services Configuration
===============================================================

This section contains information on how to configure WAN
Services using the WAN Services Configuration program.


Saving Unfinished Configuration Files
-------------------------------------

The WAN Services Configuration program will allow you to save 
an unfinished configuration file or a configuration that
contains errors. It will, however, warn you where the first
error occurs and that it will not create the corresponding
EC.CFG file that has to be loaded onto the EiconCard.

Note   Saving an incomplete configuration, or configuration
       with errors cannot be used by the EiconCard until the
       configuration is completed or corrected. Do not attempt
       to start the EiconCard until a proper configuration has
       been saved.



EiconCard
===============================================================

The following items are specific to EiconCard hardware.


General
-------

If you configure any EiconCard with the "Clocking" parameter
set to INT+DPLL and the "Data Encoding" parameter set to NRZI,
you must not set the "Line Speed" parameter any higher than
19200 bps.

All of these parameters are found in the Sync configuration
panel in the WAN Services Configuration program. 


EiconCard S51 and ISDN/PC EiconCard
-----------------------------------

The HAYES(tm) AT dialer option is available in the WAN Services
Configuration program for both the EiconCard S51 and ISDN/PC
EiconCard, although it is not supported at the time of this
release. The HAYES AT dialer option should not be selected for
either of these EiconCards.


Installing EiconCards in an EISA Computer
-----------------------------------------

WAN Services for Windows NT includes EISA configuration files
that must be used with the EISA Configuration Utility (ECU). 
The two files supplied are described below.
                                                     
 EISA Configuration file   EiconCards Supported              
                                                        
 !EICEC00.CFG              EC/PC and older revisions* of the 
                           following models that do not support
                           the extended interrupts (IRQ 10-15):
                           HSI/PC, DPNA/PC, MPNA/PC. 
                  
 !EIC15A0.CFG              HSI/PC, DPNA/PC, MPNA/PC, ISDN/PC, 
                           IMC/PC, EICONCARD S51.
                             

*Older revisions of the above mentioned models are 
distinguished by the fact that they do not have a 16-bit bus
connector. 

Eicon Technology recommends that you run the ECU before
physically installing the EiconCard. This will allow you to 
make switch settings on the card before inserting the
EiconCard in the PC.

Most ECUs have similar implementations. Follow the generic
steps below to install and configure your EISA PC to use an
EiconCard: 

1  Start the ECU and follow the manufacturer's instructions to
   add an adapter in an empty slot.

2  The ECU will present you with a list of adapter 
   configuration files. Follow the manufacturer's instructions
   to load an OEM configuration file. Get Eicon EISA
   configuration files from the I386/CORE and ALPHA/CORE
   directories of the WAN Services for Windows NT CD-ROM. 

   Note   If your ECU does not support access to CD-ROM files,
          then you must copy the EISA configuration files
          (!EIC*.CFG) from the WAN Services CD-ROM onto a
          disk before running the ECU. 

3  Select the proper Eicon EISA configuration file from the 
   list. 

4  When the EiconCard definition is properly added for one of 
   the empty slots, exit this menu and go to the View Details
   or Edit Details menu.

5  From the View Details or Edit Details menu, locate the slot
   configured for the EiconCard. The system will have already
   produced a conflict-free configuration based on the card
   capability and the resources already used on the system. You
   may re-configure the I/O port, IRQ, and shared memory
   address to suit your needs.

   Note   Special consideration should be made when installing
          an ISA EiconCard in an EISA PC. If the PC contains
          16-bit peripheral ISA cards which use memory windows
          (such as LAN or video adapters), then the EiconCard
          cannot share the same 128k memory group address. 

          The 128k memory group addresses are as follows:
  
                A000-BFFF 
                C000-DFFF 
                E000-FFFF

          For example, if you have a 16-bit LAN card which uses
          a memory window at C800-CFFF then you would not be
          able to put your EiconCard, or any other 8-bit card
          which uses a memory window, at any address in the
          C000 to DFFF range. 
          If there is difficulty in managing the memory 
          addresses, most peripheral 16-bit cards can be
          configured as 8-bit cards. This can usually be done
          through jumper selections on the card or by putting
          the 16-bit card in an 8-bit slot. Check the
          manufacturer's documentation for their 
          recommendations. 

6  Once the configuration is complete, you must "lock" it. On
   most systems, this is done through the Advanced menu.

7  On the Examine Required Switches menu there is a diagram of
   the EiconCard I/O port address switch block (SW1) with the
   proper ON/OFF settings to match the configured I/O port. 

8  Set the switches on the EiconCard SW1 switch block as they
   appear in the diagram. 

9  Save the configuration and exit the ECU.

10 You can now shut down your PC and physically install the
   EiconCard in the proper slot.

   Note   When configuring your EiconCard with the WAN
          Services Configuration program, you must use the
          same values that you used to configure the EiconCard
          with the ECU. 



Microsoft and Eicon SNMP Services
===============================================================

This section contains information on the Microsoft SNMP
Services and Eicon SNMP services.


Microsoft's Route Facilities
----------------------------

To use Microsoft's Route facilities (ADD, DELETE, PRINT) as
well as Performance Monitor with IP, you must revert to the
Microsoft INETMIB1.DLL. Follow these steps:

1  Stop the Microsoft SNMP Agent in the Service Control Panel.

2  Execute ECINET UNINSTALL from the command line. The Eicon
   INETMIB1.DLL is replaced by the Microsoft INETMIB1.DLL.

3  Restart the Microsoft SNMP Agent in the Service Control 
   Panel. 

4  From the Eicon SNMP Console, you can now use Route 
   facilities and Performance Monitor.



Monitoring X.25 LAPB Statistics
-------------------------------

When monitoring X.25 LAPB Statistics from the Eicon SNMP 
Console, incorrect zero values for the X.25 parameters may be
displayed. This occurs because you are using the Microsoft
version of INETMIB1.DLL. 

To properly monitor X.25 LAPB Statistics from the Eicon SNMP
Console, you must install the Eicon version of INETMIB1.DLL as
follows:

1  Stop the Microsoft SNMP Agent in the Service Control Panel.

2  Execute ECINET INSTALL from the command line. ECINET.EXE was
   installed at the same time as the Eicon SNMP Console 
   program. The Microsoft INETMIB1.DLL is replaced by the Eicon
   INETMIB1.DLL.

3  Restart the Microsoft SNMP Agent in the Service Control 
   Panel. 

4  From the Eicon SNMP Console, you can now monitor X.25 LAPB
   Statistics accurately.


RTRAPI.DLL Error Message
------------------------

The Eicon Remote Management Services include the Eicon SNMP 
agent which works with the Microsoft SNMP agent. The Remote
Management Services allows the WAN Services PC to be monitored
by the Eicon SNMP Console.

If you are using the Remote Management Services and you have 
not installed the IP Routing Services, you will receive the
following error message when starting the Microsoft SNMP
Services: 

   The dynamic link library RTRAPI.DLL could not be found in
   the specified path.

This message may be ignored if you are not using the IP Routing
Services. Click the OK button to bypass this message. 
Microsoft's SNMP Services and Eicon's Remote Management
Services will not be affected.




IP Routing Services
===============================================================

This section contains information on configuration and
operation of the IP Routing Services.


Backup Connections
------------------

This section contains information on configuring and
using backup connections with the IP routing Services


ISDN/PC EiconCard

If you are using an ISDN/PC EiconCard with the optional HSI
port, certain precautions must be taken for backup connections
to function properly: 

* If you have the HSI port configured as the primary
  connection and the ISDN port as the backup connection, you
  must make sure that the ISDN port (backup) "Idle Timer" is
  set to more than one second. The Idle Timer parameter is
  found in the X.25, Frame Relay, or PPP configuration panel in
  the WAN Services Configuration program.  The Idle Timer
  parameter is made available after clicking on the Details
  button in the WAN Services Configuration program.
  
* If you have the ISDN X.25 port configured as the primary
  connection and the HSI X.25 port as the backup connection,
  you must make sure that the "Number of Retries" is set to
  more than zero on the ISDN (primary) port. You must also
  ensure that either the local or remote router has a higher
  number of retries than the other. The "Number of Retries"
  parameter is found in the Router Connection Information
  dialog box in the WAN Services Configuration program.
  
  
X.25 SVC Backups 

When using an X.25 switched virtual circuit (SVC) backup
connection for a primary connection using an X.25 virtual 
circuit (SVC or PVC), you must ensure that both the primary and
backup connections increase the of "Number of Retries" from the
default value of 0 to a minimum of 5. This parameter is found
in the Router Connection Information dialog box in the WAN
Services Configuration program. 


ECNDIS Driver
-------------

The NET STOP ECNDIS command does not function properly at this
time. If changes have been made to the IP Routing Services
configuration that necessitate the stopping and restarting of 
the ECNDIS driver, then you must reinitialize the ECNDIS
driver by rebooting your WAN Services PC to start the IP
Routing Services with the updated configuration.


Frame Relay and Cisco Routers
-----------------------------

Contrary to what is stated in the WAN Services for Windows NT
System Guide, WAN Services for Windows NT does interoperate 
with Cisco routers using Frame Relay.





SNA Server Considerations
===============================================================

This section contains information about operating WAN Services
for Windows NT and Microsoft's SNA Server.


General
-------

If you encounter problems using SNA Server and the Eicon SNA
Links drivers, (ECX25 and/or ECSDLC) try stopping and
restarting SNA Server to rectify the problem. If the problem
persists, contact your Eicon Technology representative.


Starting and Stopping SNA Server
-------------------------------- 

If WAN Services for Windows NT is running and you stop SNA
Server, Eicon Technology strongly recommends that you wait a
minimum of 30 seconds before restarting SNA Server. This will
allow SNA Server to properly shut down all processes before you
attempt the restart.



X.PAD and RAS
===============================================================

This section contains information about X.PAD and Microsoft's
Remote Access Service (RAS).



General
-------

Remote Access Service (RAS) may sometimes finish loading before
the EICONCARDS service has finished loading. In this case,
some X.PAD COM ports that RAS has configured as "Receive Calls
Only" or "Dial-Out/Receive Calls", may not be in Listen mode.
The main symptom is a RAS client calls in but cannot connect.
The usual X.25 clearing cause that displays from the client
workstation is Cause 0, Diagnostic 40 (hex). For more
information on cause and diagnostic codes, refer to Appendix
C, "User Facilities and DTE Address Structure" in the WAN
Services for Windows NT System Guide.

To determine if an X.PAD COM port is not in the Listen mode, 
use the command-line utility ECMODULE as shown below:

   ECMODULE STATUS /L

     ECMODULE 3.02 Rev. 08
     Copyright (c) Eicon Technology Corporation 1994. All
     Rights Reserved.
     Application    Protocol Connection
     Name           Name     ID  State                     Port
      ---------------------------------------------------------
     Card number : 1 
     XPAD-X.28 1988 X.25     38 LISTENING @15:32:13 Oct 20    1
     XPAD-X.28 1988 X.25     31 LISTENING @15:32:13 Oct 20    2

     Card number : 2
     XPAD-X.28 1988  X.25    26 LISTENING @15:32:13 Oct 20    3
     XPAD-X.28 1988  X.25    28 LISTENING @15:32:13 Oct 20    4

     Command completed successfully.

You should see "LISTENING" for each X.25 port that X.PAD uses
and RAS has opened and configured as "Receive Calls Only" or
"Dial-Out/Receive Calls." The above example shows four X.PAD
ports, each configured to use a different EiconCard X.25 port.

If the X.PAD COM ports state is not "LISTENING", you will
have to stop and restart RAS to rectify the problem.

Follow these steps to stop and restart RAS:

1  From the command-line, type:

          NET STOP REMOTEACCESS

and then press ENTER. This will stop RAS.

2  To restart RAS, type:

          NET START REMOTEACCESS

and then press ENTER. This will restart RAS.

After restarting RAS, use the ECMODULE STATUS /L command to
confirm that the status of each X.PAD COM port is "LISTENING."




Command-Line Utilities
===============================================================

This section contains updated information on the command-line
utilities included with WAN Services for Windows NT.


ECMODULE
--------

The ECMODULE STATUS /Listen command returns listen pendings on
all EiconCards. You can now use the additional switch 
/Eiconcard n, where n is the number of the EiconCard. For
example the command, 

ECMODULE STATUS /L /E 2

will give you all listen pendings for EiconCard #2 in your WAN
Services PC.



MPRCCT ADD X25 Command
----------------------

The MPRCCT ADD command is used to create an X.25 circuit which
can later be mapped to a remote IP address using IPMAP.

The parameters presented below are for the MPRCCT ADD X25
command. These parameters are not new, but the information 
below updates the information contained in the WAN Services for
Windows NT System Guide.

             
 Parameter                 Description                
                
 /IF facilities            X.25 Listening Facilities: input 
                           facility settings for incoming and
                           two-way circuits. For example: /F
                           42,8,8 sets packet size to 256
                           instead of 128 characters. 
                           This parameter is a string of up to
                           109 characters which represents the
                           X.25 User Facilities that are
                           present in your X.25 network
                           subscription, and are to be used
                           for this connection between the
                           local and remote routers.

                           If the /U userdata parameter string
                           consists of more than 16 characters,
                           then the /IF facilities string must
                           contain the Fast Select Facility.
                           This is done by including the 
                           hexadecimal string 01,8x, where x
                           is any valid bit. If the Fast Select
                           Facility is contained in the /IF
                           facility string, this will allow 128
                           characters in the /U userdata
                           string. 
                                        
 /OF facilities            X.25 Calling Facilities: output
                           facility settings (two-way and
                           outgoing circuits only). 
                           This parameter is a string of up to
                           109 characters which represents the
                           X.25 User Facilities that are
                           present in your X.25 network
                           subscription, and are to be used
                           for this connection between the
                           local and remote Routers. 
                        
                           If the /U userdata parameter string
                           consists of more than 16 characters,
                           then the /OF facilities string must
                           contain the Fast Select Facility.
                           This is done by including the 
                           hexadecimal string 01,8x, where x
                           is any valid bit. If the Fast Select
                           Facility is contained in the /IF
                           facility string, this will allow 128
                           characters in the /U userdata
                           string.
                            
 /U userdata               The User Data parameter consists of
                           a  case-sensitive string of up to
                           128 alphanumeric characters.If the
                           userdata string consists of more
                           than 16 characters then the /IF 
                           facilities or /OF facilities string 
                           must contain the Fast Select
                           Facility. 
            

Note   If you are using the hexadecimal format to write your
       User Data or Facilities string, realize that each
       hexadecimal character is counted towards the maximum 
       alphanumeric characters allowed. For example, the
       hexadecimal string "01,02" consumes 5 characters. This
       limits your User Data string to 43 characters and your
       Facilities string to 36 characters, if you use
       hexadecimal format. 




Eicon SNMP Console
===============================================================

This section contains information relevant to operating the
Eicon SNMP Console.


Eicon SNMP Console INSTALL Program
----------------------------------

* You must use a mouse when installing the console.

* Approximately 5 MB of disk space are required to install the
  Eicon SNMP Console.

* The INSTALL program does not support periods "." in the
  pathname. 


Insufficient Disk Space
                       
You may receive an EPFIQ185 error which indicates that you do 
not have sufficient disk space to install all the Console
files. If you are installing the software for the first time,
you must make space available on your drive before proceeding
with the installation. Therefore, for new installations, select
"No" when asked to continue the install process. The install
program also requires about 1 MB of temporary disk space to
run, so 5 MB are required to install the program.

If you are re-installing software, you may choose "Yes" to
continue, but you must select the Overwrite Files option. If 
you still have insufficient disk space, you will have to make
space available on your drive.


Uninstalling the Eicon SNMP Console
-----------------------------------

This section contains information about uninstalling the Eicon
SNMP Console.


Deleting files manually
                   
You should not directly delete files from your local file
directory. File removal should only be done via the 
Installation and Maintenance Utility which is installed in
your program group. Deleting these files manually may cause
loss of historical information which may affect future
installation procedures. Listed below are the files that could
cause difficulties if deleted manually. These files are
located in your \WINDOWS or default installation directories
(\ECSNMP). 

   EPFWCAT.PKG
   EPFWHCNF.CNF
   EPFWIS.INI
   ECSNMP.PKG
   ECSNMP.ICF
   ECSNMP.DSC



Deleting the Installation and Maintenance Utility
             
When running the EPFIDEFI.BAT file (described in System
Guide), you may encounter a "Batch file missing" message.
This indicates that the EPFIDEFI.BAT is trying to delete
itself. Simply ignore this message. 


Eicon SNMP Console Limitations
------------------------------

This section describes limitations which may affect operation
of the Eicon SNMP Console.


Modifying IP Filters
                    
If you want to modify existing IP Filters for a router circuit,
you must first stop that circuit.

To modify an IP Filter for a selected circuit, follow these
steps: 

1  From the Router Connection panel, highlight the circuit for
   which you want to modify the IP filter.

2  From the toolbar, click the Stop button to stop the
   highlighted circuit.

3  Click the Components button from the toolbar. This brings
   up the IP Filter panel.

4  Double-click the IP Filter that you wish to modify. This
   brings up the IP Filters configuration panel.

5  Make the required modifications to the filter. Repeat
   steps 4 and 5 for additional IP Filters.

6  Click the OK button.

7  From the Router Connection panel, make sure that the circuit
   you just stopped is highlighted. From the toolbar, click
   the Start button to restart the highlighted circuit.


Deleting Router Circuits
                        
When deleting circuits from the Router panel, it is recommended
that you first delete all the IP filters associated with that
circuit. 

To delete IP filters for a selected circuit, follow these 
steps: 

1  From the Router Connection panel, highlight the circuit for
   which you want to delete the IP filters.

2  Click the Components button from the toolbar. This brings
   up the IP Filter panel.

3  Highlight the IP Filter entry you want to delete and press 
   the Delete key.

4  Repeat Step 3 until all IP Filters have been deleted. 

5  Return to the Router Connection panel, highlight the
   circuit you wish to delete and press the Delete key.


ISDN and Dialer Functions
                         
If you are monitoring a WAN Services PC with an ISDN EiconCard
configured with TPH1962 (Australia), VN3 (France), or BTNR191
(United Kingdom), you will not have use of any of the Dialer
commands which are located in the Operations menu.

The command-line utility ECDIALER supports all of the above 
ISDN switches. Refer to Chapter 8, "Command-Line Utilities" in
the WAN Services for Windows NT System Guide for more
information on the ECDIALER command.


IP Addresses
            
To monitor a WAN Services PC which is using IP Routing 
Services and has two or more IP addresses, you must specify
the IP address which is closest to the Eicon SNMP Console. For
example, with a configuration as illustrated below,


EICON
SNMP CONSOLE--------PC #1----X.25 PSDN-----PC #2
                    |   |                  |  |
                    |   |                  |  |
     IP 192.219.20.20   |   IP 192.219.30.40  |
                        |                     |
                        IP 192.219.30.30      IP 192.219.40.40
                                                  
                                                                           
you must specify IP address 192.219.20.20 in the Eicon SNMP
Console to monitor the WAN Services PC #1 and IP address
192.219.30.40 to monitor WAN Services PC #2.


Restarting WAN Services 
                        
If you use the Eicon SNMP Console to stop the IP Routing 
Services in a WAN Services PC that is not on the same subnet
as the Console, you will not be able to restart the IP Routing
Services from the Console as the connection is now broken.

For example, in the diagram above, if you were to stop the IP
Routing Services on the WAN Services PC #2, you would not be 
able to restart it using the Eicon SNMP Console. The link
between WAN Services PC #1 and WAN Services PC #2 is now down
and the Eicon SNMP Console cannot connect to the WAN Services
PC #2. 


Using the Console on a WAN Services PC

If you install the Eicon SNMP Console on a WAN Services PC that
is using IP Routing Services, you must ensure that the EICONRIP
service is enabled. If you choose to disable the EICONRIP
service, you must install and run the Eicon SNMP Console from a
remote workstation.
