Release Notes 213-104-09 March 22, 1996 WAN Services for Windows NT V3R4 Introduction =========================================================================== These Release Notes apply to the Eicon Technology WAN Services for Windows NT V3R4 product; they supersede any corresponding information in the WAN Services for Windows NT System Guide (206-100). These Release Notes are organized as follows: General Limitations Corrections Upgrading to V3R4 WAN Services for Windows NT EiconCards IP Routing Services X.PAD Considerations General =========================================================================== * At this time, the XPAD/RAS combination is the only function of WAN Services which supports X.25 CCITT/ITU Recommendation 1988. All other functions of WAN Services for Windows NT support X.25 CCITT/ ITU Recommendation 1984. * When manually configuring the memory address of an inactive EiconCard using the Adapter Properties dialog box, the memory segments C0000- C7000, CC000, and CD000 may appear to be free when they are actually being used by another system component. This is a limitation of the system component improperly advertising its used resources to Windows NT. * If you are running Windows NT 4.0 with a Motorola Power Stack, you must upgrade the firmware to version 2.06A or later to successfully operate WAN Services for Windows NT V3R4. With other RISC PCs (PowerPC, DECAlpha, or MIPS), the firmware may also need to be upgraded. Check with the PC manufacturer or the Windows NT release notes. Limitations =========================================================================== * If more than 250 X.PAD ports are configured for any one EiconCard, you may not be able to use some of the command-line utilities, such as ECMODULE and ECDIALER. To use these EiconCard commands, you must reduce the number of configured X.PAD ports per EiconCard to below 250. Corrections =========================================================================== * Contrary to what is stated in the WAN Services for Windows NT Online Manual, EiconCards with 512KB of memory will not fully support all possible WAN Services configurations. Eicon Technology recommends using EiconCards with at least 1MB of memory. Upgrading to V3R4 =========================================================================== This section contains information on upgrading your WAN Services for Windows NT software to WAN Services for Windows NT V3R4. To upgrade to WAN Services for Windows NT V3R4, follow these steps: 1 At the Windows NT console, log on as Administrator or equivalent. 2 Insert the Windows NT 4.0 CD into your CD-ROM drive. 3 In Control Panel, double-click the Network icon to start the Network Control Panel Applet (NCPA). 4 In the Network dialog box, click the Adapters tab. Select any EiconCard from the Adapters list and click Update. Note Avoid clicking the Properties or Remove buttons in this dialog box before upgrading your system to WAN Services V3R4. If you click either of these buttons, the upgrade will not work. In this case, you must uninstall your current version of WAN Services by running WANCLEAN.EXE, and then reinstall WAN Services for Windows NT V3R4 from the beginning. See “Aborted Installation” below for the location of the WANCLEAN.EXE program on the Windows NT 4.0 CD. 5 You will be prompted for the path to the OEMSETUP.INF file, which is provided on the Windows NT 4.0 CD. Enter the appropriate path for the platform you are using, as shown in the following table: ---------------------------------------------------------------------- | CPU Platform : Location | |--------------------------------------------------------------------| | i386 : DRVLIB\NETCARD\X86\EICON | |--------------------------------------------------------------------| | MIPS : DRVLIB\NETCARD\MIPS\EICON | |--------------------------------------------------------------------| | Alpha : DRVLIB\NETCARD\ALPHA\EICON | |--------------------------------------------------------------------| | PowerPC : DRVLIB\NETCARD\PPC\EICON | ---------------------------------------------------------------------- 6 Follow the on-screen instructions to complete the software upgrade of WAN Services for Windows NT. Your Windows NT system must be shut down and restarted for the changes to take effect. WAN Services for Windows NT =========================================================================== This section contains information relevant to installing and configuring WAN Services for Windows NT V3R4. Aborted Installation -------------------- If the WAN Services for Windows NT V3R4 installation aborts for any reason, you must run the WANCLEAN.EXE program to remove any files or registry entries that were left on your PC by the aborted installation. After running this program, restart the installation from the beginning. The WANCLEAN.EXE program is stored in the following locations on the Microsoft Windows NT 4.0 CD: ------------------------------------------------------------------------- | CPU Platform : Location | |-----------------------------------------------------------------------| | i386 : DRVLIB\NETCARD\X86\EICON\I386\WANCLEAN.EXE | |-----------------------------------------------------------------------| | MIPS : DRVLIB\NETCARD\MIPS\EICON\MIPS\WANCLEAN.EXE | |-----------------------------------------------------------------------| | Alpha : DRVLIB\NETCARD\ALPHA\EICON\ALPHA\WANCLEAN.EXE | |-----------------------------------------------------------------------| | PowerPC : DRVLIB\NETCARD\PPC\EICON\PPC\WANCLEAN.EXE | ------------------------------------------------------------------------- Disabling the Eicon RIP Service ------------------------------- The Microsoft Service Pack 2 provided with Windows NT (version 3.51 and later) contains the IP RIP Service required to operate WAN Services for Windows NT. Earlier versions of WAN Services for Windows NT with IP Routing Services (V3R2a or earlier) supplied their own Eicon RIP Service. When upgrading from an earlier version to V3R4, this Eicon RIP Service is automatically replaced by Microsoft's IP RIP Service during installation of the WAN Services for Windows NT product. Note With Windows NT 4.0, Microsoft RIP Service is supported on the NT Server only. Therefore, on the NT 4.0 Workstation, you can only use static routes (Microsoft's ROUTE command). Dynamic routes are not supported on the Windows NT 4.0 Workstation. Configuration ------------- This section contains information on how to configure WAN Services for Windows NT using the WAN Services Configuration program. X.25 Maximum Packet Size Considerations When configuring an X.25/HDLC or X.25/SDLC connection using the WAN Services Configuration program, make certain that the HDLC or SDLC Maximum Frame N1 (octets) size is at least 8 bytes larger than the X.25 Maximum Packet size. For example, if you configure the X.25 Maximum Packet size to 256, then you must configure the HDLC or SDLC Maximum Frame N1 (octets) size to at least 264. The X.25 Maximum Packet size parameter is located in the X.25 configuration panel, and the HDLC and SDLC Maximum Frame N1 (octets) size parameters are found under the HDLC and SDLC configuration panels, respectively. 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. Router Connection Filters ------------------------- The number of router connection filters activated on a connection is limited by the Max IP Filters setting in the Eicon Router Driver parameters dialog box of the Network Control Panel. Although it is possible to define more filters in Eicon Configuration Manager than you have defined in the router driver configuration, these additional filters are not accepted by the driver, and are therefore not activated on the connection. To correct this problem, increase the Max IP Filters setting in your router driver configuration. See "Configuring the Router Driver and NDIS Adapter" in Chapter 4 of the WAN Services for Windows NT Online Manual for further information. Uninstalling WAN Services ------------------------- This section contains information about uninstalling WAN Services for Windows NT. Contrary to what is said in the WAN Services for Windows NT System Guide (206-100), it is not necessary to use the NET STOP EICONNDISROUTER and MPR STOP commands prior to removing WAN Services for Windows NT or the IP Routing Services. These commands are performed automatically by the Uninstall program. Removing the WAN Services Directory When uninstalling the WAN Services for Windows NT, the WAN Services directory (default is C:\WSNT) is normally removed automatically. It may fail to be removed for any of the following reasons: * Extra files were manually copied or created in the WAN Services directory, such as a log file or TRACE file * A DOS box is open and is in the WAN Services directory (default is C:\WSNT) * File Manager is open and its focus is the WAN Services directory (default is C:\WSNT) * The WAN Services Configuration program (ECADMIN.EXE) is running If any of the preceding conditions prevented the WAN Services directory from being deleted, you must manually delete the directory. EiconCards =========================================================================== The following items are specific to EiconCard hardware. General ------- * This version of WAN Services for Windows NT does not support the EiconCard NA, EiconCard SPCC, ACC8/PC, and the ISDN/PC EiconCard, which are obsolete. Limitations ----------- * When adding a new EiconCard through the Network Control Panel, make sure that the Eicon Configuration Manager is closed. If you leave this program open, it will behave abnormally when you try to configure the new card. * 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. * If you configure any EiconCard with the Clocking parameter set to "INT+DPLL" and the Data Encoding parameter set to "FM0" or "FM1", you must not set the Line Speed parameter any higher than 38400 bps. * If you configure any EiconCard with the Clocking parameter set to "INT", you must make sure that the cable(s) are properly attached and terminated on the other end. Failure to do so may result in an Out of State condition for the EiconCard. It may also cause the EiconCard commands (ECCARD, ECMODULE, and ECDIALER) not to function properly. All of these parameters are found in the Sync configuration panel in the WAN Services Configuration program. EiconCard C21 ------------- * The EiconCard C21 cannot be used on a PC running Windows NT 4.0 (Beta version) and installed with an AHA1520/1522 SCSI adapter from Adaptec. This is due to an I/O port conflict between the SCSI adapter driver and the Plug and Play interface of the EiconCard C21. * When used with the EiconCard C21, the ECCARD LIST command displays information stored in the registry instead of the actual configuration information stored on the EiconCard. Therefore, if you have changed your configuration but not yet reloaded the EiconCard, the information provided by executing the ECCARD LIST command will not reflect the active configuration on your EiconCard C21. To avoid this problem, be sure to reload the EiconCard after changing the configuration and before executing any commands. * With the EiconCard C21, traces must be enabled from the Eicon Configuration Manager instead of from the command line. The parameters controlling this function (Mail and NCB) appear on the Card PC panel when you select the Advanced option from the Parameters menu. EiconCard C21 Limitations For this release of WAN Services for Windows NT, a maximum of two ports can be operated successfully on the EiconCard C21. In addition, you must ensure that the card resources allocated to these ports are configured to the minimum values required to support your connections. Configurations using more than one protocol on the same EiconCard C21 may have problems loading due to memory limitations. This problem is indicated by an error message stating that the configuration is not loadable, received after you issue the ECCARD START command. In most cases, this problem can be resolved by reducing the card resources specified in the configuration (for example, reducing the Window Size or Call Directory Entries values in Connection Manager). However, a few configurations will still be unable to load, even when card resources are reduced. The table on the next page identifies these configurations. Eicon Technology recommends that you avoid using these configurations whenever possible. Note The limitations presented in the table were applicable at the time of release. Due to the wide range of configuration factors affecting card performance, this information should be taken as a guideline only.

Detecting EiconCards -------------------- WAN Services for Windows NT automatically detects EiconCards installed in the host machine using native Windows NT facilities (not Plug and Play). However, some older versions of the DPNA, HSI, MPNA, and EC/PC EiconCards (those manufactured before 1990) cannot be detected. For these cards, you must enter the I/O port address, slot position, IRQ level, and memory address settings manually on the Settings page of the Adapter Properties dialog box. This dialog box pops up when you install a new card through the Network Control Panel. EiconCards and 16-Bit Adapter Cards ----------------------------------- Special consideration should be made when installing an ISA EiconCard in an ISA or 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. Most of Eicon Technology's EiconCards now support memory segments in extended memory addresses of FC000-FEF00, however, these memory addresses can only be used on PCs with 16MB of RAM or less. If you receive the following error message in the Event Viewer: ECNB: "/dev/EEC: Possible shared memory window conflict with a 16-bit adapter." while operating the EiconCard, then Eicon Technology recommends the following steps: * Change the EiconCard memory address to the E000 range * If the E000 range does not work then try the B000 range, if that EiconCard supports it * If there is still a problem with trying to get your EiconCard and 16-bit adapters to work together, contact your Eicon Technology representative The address range B000-BF00 is not supported on EISA PCs or multi- processor machines. I/O Port Settings and EiconCard Detection ----------------------------------------- * WAN Services for Windows NT may fail to detect an EiconCard installed in your PC if that card's I/O port setting conflicts with the setting of another card or peripheral device installed in the same PC. Ensure that all EiconCards are set to an unused I/O port. * If you install multiple EiconCards of the same type in the same PC and give them all the same I/O port setting, WAN Services for Windows NT sees them as a single EiconCard. Therefore, only one instance of that EiconCard type will be detected and listed in the Detection dialog box. To detect all EiconCards, you must assign each one a unique, unused I/O port setting. ISDN Connections ---------------- * If, on an active ISDN port, the ISDN line is physically disconnected then reconnected, the port may not reactivate. To reactivate the port you must issue the ECDIALER command from the WAN Services PC command line. Follow the example below, ECDIALER DIAL /Port p /Number n where p is the ISDN port number and n is the number you want to dial, to reactivate an ISDN port. * If the ISDN cable is disconnected, all current calls in progress are dropped. The ISDN physical layer is reactivated after the reconnection of the cable. The ISDN dialer does not re-establish the calls. The application in use (for example, IP Routing Services) must re-establish the calls. Some applications do this automatically, whereas with other applications you must manually redial. See the documentation that accompanies the application you are using for more information. In all situations, please ensure that your cables are connected before starting WAN Services. * The ECMODULE STATUS command is unable to provide "listen pending" information for ISDN connections. 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, IMC/PC, | | : EICONCARD S51. | ------------------------------------------------------------------------- *Older revisions of the abovementioned 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 the Eicon EISA configuration files from the following directories on the Windows NT 4.0 CD: ---------------------------------------------------------------------- | CPU Platform : Location | |--------------------------------------------------------------------| | i386 : DRVLIB\NETCARD\X86\EICON | |--------------------------------------------------------------------| | MIPS : DRVLIB\NETCARD\MIPS\EICON | |--------------------------------------------------------------------| | Alpha : DRVLIB\NETCARD\ALPHA\EICON | |--------------------------------------------------------------------| | PowerPC : DRVLIB\NETCARD\PPC\EICON | ---------------------------------------------------------------------- Note If your ECU does not support access to CD-ROM files, then you must copy the EISA configuration files (!EIC*.CFG) from the Windows NT 4.0 CD 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. 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. 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. IP Routing Services =========================================================================== This section contains information on configuration and operation of IP Routing Services. Backup Connections ------------------ This section contains information on configuring and using backup connections with the IP Routing Services. * You must make sure that the port configured as the backup connection, has the Idle Timer parameter set to more than one second. The Idle Timer is found in the X.25 configuration panel in the WAN Services Configuration program. The Idle Timer is made available after clicking the Advanced button in the WAN Services Configuration program. * You must make certain that the local and remote routers' Number of Retries and Delay parameters have different values. This will make sure that they do not keep retrying at the same time. Setting the Number of Retries to a different value on each side will ensure that after the connections retries are exhausted on one side the other side will continue to try make the connection. The Number of Retries and Delay parameters are found in the Router Connection Information dialog box in the WAN Services Configuration program. * If you are configuring a primary connection for use over an X.25 two-way dialup connection and using the Hayes AT(tm), V.25bis, or ISDN dialer, you must make certain that the Inactivity Timeout parameter is set to 300 seconds or more, or it is set to zero (default), which means there is no timeout. The Inactivity Timeout 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 increase the Number of Retries for both the primary and backup connections 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 ------------- 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. This is because the ECNDIS driver depends on other Microsoft services that cannot be stopped. Multi-Processor PCs ------------------- When using IP Routing Services on a multi-processor PC, you must make certain that the Global Pool Tx Buffers parameter is set to zero (default). The IP Routing Services may fail to function if this parameter value is set any higher than zero. To configure the Global Pool Tx Buffers parameter follow these steps: 1 In the Network Control Panel Applet (NCPA), highlight the "Eicon Router Driver" entry in the Installed Network Software list, and click Configure. 2 Enter zero (0) for the Global Pool Tx Buffers parameter, and click OK. Connecting to an Eicon Technology ICS or ICR -------------------------------------------- Maximum Transmission Units (MTUs) are not configurable on an Eicon Technology InterConnect Server (ICS) or InterConnect Router (ICR). Both ICS and ICR use a default MTU of 1492. Therefore, when connecting a WAN Services PC to an ICR or ICS using IP Routing Services, you must configure the MTU parameter, on the WAN Services PC, to a value of 1492. Follow these steps to configure the MTU value: 1 In the NCPA, highlight the appropriate instance of the Eicon NDIS Adapter entry in the Installed Adapter Cards list, and click Configure. 2 Enter 1492 as the MTU value in the Logical Adapter Configuration dialog box, and click OK. Connecting to a Cisco Router ---------------------------- When configuring the CHAP authentication protocol on a connection between a WAN Services for Windows NT router and a Cisco router, you must set the Host Name and User Name parameters on the Cisco router to identical values. These values must also match the value of the User Name parameter configured on the WAN Services for Windows NT PC. X.PAD Considerations =========================================================================== This section contains information on operating WAN Services for Windows NT with X.PAD. Configuring X.PAD ----------------- In most cases, when configuring X.PAD for use with RAS or other binary transfer protocol via third-party communication programs, no configuration other than adding the port is required. The default settings for the X.PAD ports are sufficient for most setups. X.PAD and RAS ------------- RAS does not support the setting of "Any X.25 port" as a device in RASPHONE when used with X.PAD. When configuring RASPHONE Phone Book entries for use with X.PAD, you must select the specific COM ports that are configured for use by X.PAD X.PAD and 16-Bit Communications programs ---------------------------------------- X.PAD is optimized for use with Microsoft Remote Access Service (RAS). There may be some incompatibilities or poor performance when used with older 16-bit communications programs running under Windows NT. ########## End of 213-104-09 ##############################################
