2 Starting and Terminating NE-UniGATE

2.1 Short DescriptionNE-UniGATE is a transparent software platform for all Siemens ICN ON NE applicationsoftware. It supports network elements with QD2, QST, and Q3 telegram protocols. NE-UniGATE provides access to network elements via a network interface (Ethernet) or viaa serial line interface (RS232).

In addition, NE-UniGATE (NCT only) contains an NE-Proxy service that allows access-ing OSI networks via the internet, i.e. even from the operator’s home. One NE-Proxy canserve multiple NE-UniGATE operators.

NE-UniGATE’s menu items and dialogs allow the supported communication channelsto be selected and configured. The network element to be operated is selected by a sim-ple procedure, adapted to the requirements of the connected communication channel.

NE-UniGATE enables addresses to be assigned to the network elements. The programicons for these applications are used to present the assigned network elements in thenetwork view for the “network” communication channel. A double-click on such an iconstarts the assigned device application and thus permits the network element to be oper-ated.

There are two NE-UniGATE software variants: for a Local Craft Terminal LCT and for aNetwork Craft Terminal NCT.

2.1.1 Differences between LCT and NCTThe same basic hardware can be used for the LCT workstation and for the NCT work-station. A desktop PC is recommended for the NCT because of its better graphic display,whereas a laptop may be preferred for the LCT because of easier transportation.

The LCT is used for local or remote control and supervision of network elements. Orga-nizational relationships between network elements in the network are not available forthe LCT. The LCT can communicate with a maximum of 150 network elements, but canonly start 2 element managers at the same time.

The NCT in addition allows monitoring of all the alarms reported from each accessiblenetwork element. The NCT can communicate with a maximum of 150 network elements(including alarm monitoring), but can only start 50 element managers at a time.

2.1.2 Installation of the Program NE-UniGATE

Installation Requirements– Installation of the Ethernet Adapter Drive (if the Ethernet interface is to be used)– Installation of the TMN-DCP OSI Stack (configuration of the NSAP address of the

terminal is via the stack)

iIn order to carry out an installation the user must have the MS-Windows NT Administra-tor rights.

☞Before installing NE-UniGATE, read the Installation Manual supplied with theprogram files.

Fig. 3.2 “Offline” Window Example

NE-UniGATE uses the Notifications log output area to display messages and notesrelating to the connection setup and network access by the operating terminal to the net-work elements (see Fig. 3.1). This is of particular importance with the NCT softwarevariant.

In addition, depending on the operating mode (online/offline) and the software variant(LCT/NCT) used on the operating terminal, various message and network view windowsare available (see Tab. 3.1). The windows can also be displayed as icons. For more de-tailed information on these windows see Chapter 3.7.

3.7 Message and Network Indication Windows

3.7.1 Message WindowsThe various message windows of NE-UniGATE are almost entirely self-explanatory.

3.7.2 Notifications Log Output AreaParticularly during the boot phase of the NCT software variant numerous messages mayoccur. For this reason, instead of a series of individual message windows opening oneafter another, these messages are entered into the notifications log output area (for anexample, see Fig. 3.1).

This area displays messages relating to the setup of connections to network elementsand the login to the operating terminal.

3.7.3 “Alarm History” WindowThe “Alarm History” window is available only with the NCT software variant.

This window reports alarm messages in chronological order. All the entries, includingthose for alarms which have been cleared, are retained.

LED symbols to the left indicate the alarm severity by the corresponding alarm colors(see Tab. 3.3).

3.7.4 Alarm List WindowThe alarm list window (see Fig. 3.6) is available only with the NCT software variant, andif a network connection is established.

The alarm list comprises all selected network elements. The display shows the currentalarm state, i.e. alarms are withdrawn when they have been cleared, or if they can nolonger be called up due to a loss of communication.

LED symbols to the left indicate the alarm severity by the corresponding alarm colors(see Tab. 3.3). In addition, an unacknowledged alarm state is indicated by a blue framearound the LED symbol.

⇒ The log size and the columns displayed can be changed via the menu item <Op-tions> <Alarm Settings...>.

⇒ Filtering according to various criteria is possible by clicking anywhere in the“Alarm List” window using the right-hand mouse button and selecting <Set Fil-ter...>.

A42022-L5901-D53-3-7619 25


OMN:NE-UniGATE

Alarm Filtering Behavior

NE-UniGATE handles the time stamps for requested alarms (indicated by “<“) internallyin milliseconds. Therefore, a displayed time like 12:37:45 may be internally 12:37:44.9,which is before 12:37:45 and therefore filtered out.

An event has always a time stamp in seconds with 0 milliseconds.

The filter sorting is always “later than ...”, even if it is 1 millisecond.

The following cases could occur, if the filter is set to 12:37:45 as an example:

a) An alarm (raised by an event) at 12:37:45 has the internal time stamp 12:37:45.0and will not be displayed.

b) An alarm (requested by NE-UniGATE) arrives at 12:37:44.9 and will not be dis-played.

c) An alarm (requested by NE-UniGATE) arrives at 12:37:45.1 and will be displayed.

Since the filter sorting is always “later than ...”, even if it is 1 millisecond (see above), analarm (requested by NE-UniGATE) that arrived at 12:37:45.0 (or before) will not be dis-played.

In this case, the filter needs to be altered accordingly.

3.7.5 “Connected Devices via Serial LIne” and “Connected Devices viaNetwork” WindowsThe “Connected Devices via Serial Line” window displays the connected NE.

In the “Connected Devices via Network” window , all network elements which are ac-tive in the network are either displayed as a collection of different NE icons or in a sche-matic network view with the various connecting lines, or as a geographical layout on amap of the country.

Next to any NE icon in the network view, some small additional symbols may be dis-played (see Fig. 3.5).

☞The line properties configuration is described in Chapter 3.10.3.3.

☞The background map configuration is described in Chapter 3.10.3.4.

Fig. 3.5 Additional Network-View Symbols

3.7.6 “Offline” WindowThe “Offline” window shows all installed operating applications (for an example seeFig. 3.2). Most of these applications can be started in the offline mode, too.

3.8 Alarm Indication with the NCT Software VariantThe NCT software variant of NE-UniGATE allows alarm management over the entirenetwork.

With the LCT software variant alarm management is not provided. Although there areNE icons in the “Connected Devices via Network” or “Connected Devices via SerialLine” window, they do not indicate any alarms.

☞The alarm indicating features in the network view are described in Chapter 3.8.

Indicates that this NE is not connected.

Indicates that a user ID (name/password) is requested by the NE.

Indicates that there is at least one unacknowledged alarm with that NE.

Indicates applications already started at the NE.

Indicates that NE-UniGATE is waiting for response from that NE.

Indicates that the NE is currently not connected, but NE-UniGATE periodically tries to reach it.

May appear for a short time, indicating a current disconnecting process initiated by the user.

☞The customer documentation for the network element concerned explains theNE specific alarms.

3.8.1 “Connected Devices via Network” Window

Fig. 3.6 Schematic View of the Network with Alarm Indication

The identifier (name of the network element) appears in gray lettering for unreachablenetwork elements.

If a fault occurs, a bell symbol (Fig. 3.6) is displayed in addition to the icon for the faultyNE, and the outline of the icon flashes, for example yellow/green with a “minor” severityalarm. If several alarms have occurred, the highest alarm state is indicated.

In addition, an audible alarm (a bell sound by default) can be generated, if configured:either a single sound whenever an alarm arises or a continuously repeated sound aslong as at least one alarm is not yet acknowledged.

After an alarm has been acknowledged, the icon’s outline, which previously had beenflashing, continues to show the color for any continuing fault state. Tab. 3.3 shows thedefault color settings for each alarm severity.

3.8.2 Alarm ListThe alarm list is part of the “Connected Devices via Network” or “Connected Devices viaSerial Line” window, as shown in Fig. 3.6. An LED symbol to the left of each alarm entryindicates the corresponding alarm severity, using the same color scheme as listed inTab. 3.3 − except for green, because a cleared alarm is immediately deleted from thealarm list. A blue frame around the LED symbol indicates that the concerned alarm hasnot yet been acknowledged.

3.8.3 Alarm HistoryThe alarm history entries are supplemented by LED symbols using the same colors aslisted in Tab. 3.3.

3.8.4 Status BarThe status bar contains five LED symbols, each indicating the alarm summary of onecertain alarm severity using the color listed in Tab. 3.3. If no alarm of this severity hasoccurred, the regarding LED symbol is green.

3.9 Menu Bar and Menu Overview for NE-UniGATEThe menu bar is situated directly beneath the title bar. It contains all the menus for themain window in NE-UniGATE (see Fig. 3.7). Clicking on any of these menus opens themenu-specific pulldown menu. For a few frequently used menu items there are alsoshortcuts, e.g. “Ctrl + L” to display the “Alarm List”.Tab. 3.4 gives a summary of the menus and menu items in NE-UniGATE. More com-plete Explanations and Notes on the NE-UniGATE Gateway Software Menus can befound in Chapter 3.10 – insofar as this is necessary for operating the system.

In the pulldown menus of the user interface, active Menu items are displayed in blacklettering on a gray background, inactive menu items (e.g. when NE-UniGATE is run inoffline mode) by gray letters on a gray background.

The NE-UniGATE <Help> menu has basically the same structure as thestandard <Help> menu in MS-Windows NT (see Tab. 3.4).

34 A42022-L5901-D53-3-7619


3.10.1 <File> Menu Items

3.10.1.1 <File> <Open Configuration...> / <Save Configuration> /<Automatic Configuration Saving> / <Save Configuration as...>These menu items allow you to create, among other things, multiple network configura-tion files and to switch between them.

All network configuration changes concerning– NE addresses,– Background settings for the network view,– Symbol positions and symbol size for the network view,– Link properties for the network view,– Symbol subtitles / descriptions from the <Symbol> <Properties> window,

are currently saved into one single file: the currently active network configuration file.

If the <Automatic Configuration Saving> item is enabled, any configuration changes aresaved promptly. If this item is disabled, the current network configuration can be savedmanually using the <Save Configuration> or <Save Configuration as...> commands.

3.10.2 <Network> Menu Items

3.10.2.1 <Network> <Connect> or <Disconnect>After a successful connection setup with the network – including the requesting of all thealarm information and the alarm suppressions specific to functional units – the menuitem <Network> <Connect> changes to <Network> <Disconnect>, so that it becomespossible to break off the connection to the network. Executing this action switches intothe offline mode, in which the menu item changes back to <Network> <Connect> again.

When the “serial line” communication channel is active (preselected via <Configura-tion> <Use Serial Line Interface>), communication is set up to one accessible networkelement.

When the “network” communication channel is active (preselected via <Configuration><Use Network Interface>), communication is set up to the network elements connectedvia ethernet as well as to the network elements accessible via these network elements.With accessible network elements which are connected via the network element; all thenetwork elements which have been selected to be active (see 3.10.4.1) are displayed inthe network view window.

Automatic Reconnects

There are two kinds of automatic reconnects:– After a short loss of connection, NE-UniGATE tries to reestablish the connection

three times − if this feature is enabled via <Options> <Communication settings...><Network> “Connections/Enable Initial Connect”.

– If <Options> <Communication settings...> <Network> “Reconnect attempts/EnablePromptly Reconnect” is enabled, NE-UniGATE periodically tries to establish the con-nection − typically every 5 Minutes.

A42022-L5901-D53-3-7619 35


OMN:NE-UniGATE

3.10.2.2 <Network> <Refresh Connections>In the case of an active “Network” communication channel, the menu item <Network><Refresh connections> initiates a new connection setup to those network elementswhich could not be reached at the time of the last connection setup. Network elementswhich are inaccessible are indicated by gray identifier text beneath their program icons.

In offline mode, the menu item <Network> <Refresh connections> is grayed out (inac-tive).

3.10.2.3 <Network> <Connect to NE...> / <Disconnect from NE...> / <Stop Re-connect Attempts>When the “network” interface is used, the menu items <Connect to NE...> or <Discon-nect from NE...> are offered. Using these, it is possible to select individual network ele-ments by name from a list of those which are set active, and to disconnect them fromthe communication, or to reconnect them to it. A connection setup/disconnection canalso be achieved by using <Symbol> <Connect to NE..> / </Disconnect from NE...>.

When this is done, the disconnected elements remain in the active address list, and thusare also retained in the network representation window, but are not operable from theLCT/NCT. The names (identifiers) of such network elements are then shown in gray.

If it is not possible to establish a connection using <Connect to NE...>, a correspondingmessage will appear in the notifications log output area.

When UniGATE is not connected to the NE, it periodically tries to establish a connection− if this feature is enabled as per Chapter 3.10.2.1 (second item in the Automatic Re-connects section). This automatic reconnection function can be stopped by enabling the<Stop Reconnect Attempts> item which is displayed instead of <Disconnect from NE...>in this case.

3.10.3 <Symbol> Menu Items

3.10.3.1 <Symbol> <File transfer>In offline mode, the menu item <Symbol> <File Transfer...> is grayed out (inactive).

The FTP application software used to transmit files between the operating terminal andthe selected QD2 network element is started by <Symbol> <File Transfer...> (softwaredownload).

The prerequisites for starting the FTP application software are:– a connection from the operating terminal to the QD2 network element via the “net-

work” interface,– the user must have authorization level 2, 3 or ADMINISTRATOR.

iSome application software has a built-in download feature, some does not. In the lattercase, the FTP application software can be used for software download.However, starting the FTP application software is unnecessary for the normal opera-tion of many network elements.Information about this will be found in the customer documentation for the network ele-ment concerned.

☞The procedures to be followed for a file transfer and a software download aredescribed in the Maintenance Manual MMN for the NEs concerned.

36 A42022-L5901-D53-3-7619


After the user clicks on the menu item <File Transfer...>, the “File Transfer” dialogwindow opens (see Fig. 3.8).

Fig. 3.8 <Symbol> <File transfer>

3.10.3.2 <Symbol> <Link with Object> / <Unlink from Object...>The menu item <Link with Object> allows you to draw a line between the currently se-lected NE and another NE. This procedure can be terminated at any time by pressing“Esc” on the keyboard.

The menu <Unlink from Object> allows you to delete a line between the currently select-ed NE and another NE. The link to be removed can be selected from a popup window.

⇒ The FTP application software can be started by clicking on the network elementsymbol in the main window of the NE-UniGATE gateway software (NCT or LCT,see Chapter 2.2) and then selecting the menu item <Symbol> <File Transfer...>.

iAttempting to start the FTP software from outside NE-UniGATE by “FTP32.exe” resultsin an error message and termination of the software.

4 Marben OSI Stack

4.1 Introduction

4.1.1 PurposeThis chapter describes the configuration and operation of the Siemens / Marben OSIStack for managing communication. The installation of the stack is not covered in thisdocument. For information on installation, please refer to the setup instructions and sup-port files, delivered with the installation media.

4.1.2 SummaryThe Siemens / Marben OSI Stack is used to interconnect different systems, running onvarious platforms. The stack can be configured for multiple OSI environments and its pa-rameters may be configured to suit particular requirements such as maximum through-put or high reliability. The stack is supplemented with some tools for configuration andoperation of the communication process. It supports data transport connections on OSIlayers 4 and 7.

4.2 Contents of the OSI Stack Package

58 A42022-L5901-D53-3-7619


4.3 OSI Stack Configuration for MS-WindowsThe MS-Windows OSI stack is configured using operating terminal.

This will open the following dialog:

Fig. 4.1 Configuration of the OSI Stack for MS-Windows NT/95/98

This dialog allows the configuration of the "Local NSAP address" . The loopback maybe enabled mainly for test purposes. It allows client connections to a server on the samemachine.

If a TCP/IP stack has been installed, the “Local IP Address” field is completed by theapplet automatically from the "wsock32.dll" file. Here you can configure the IP address-es of other network adapters manually on multi-homed systems. The IP address is onlyneeded for TP0 over TCP/IP connections, as described in RFC 1006. There is no cor-relation to the selected network adapter (see "Bind to Network Interface Card" below).For RFC1006 connections of this type, routing is controlled entirely by the TCP/IP stack.

In the “Number of Channels and Ctx” field, the approximate number of connectionscan be configured.

The “Bind to Network Interface Card” combo box can only be used under MS-Win-dows NT/2000 to configure the network adapter which is used for OSI communication.You can select each network adapter with an active OSILLC protocol driver. The net-work adapters are described uniquely by their physical address (= MAC address). You

⇒ Double-click the OSI Stack icon in the MS-Windows <Start> <Settings> <Sys-tem control> window.

⇒ To ensure proper operation, you should enter approximately twice the numberof simultaneous connections required.The “Number of Channels and Ctx” must be less than 1024.

A42022-L5901-D53-3-7619 59


OMN:NE-UniGATE

can view this physical address using the command line “ipconfig /all”. If you selectMULTI in this combo box, the simultaneous use of up to 4 network adapters with an ac-tive OSILLC driver is allowed. If two network adapters are physically in the same LAN,the stack will work only with one of them. Only network adapters with an installed OS-ILLC driver are available for the OSI stack. This property can be used for 2 features:

LAN Segmentation: In some cases, the amount of traffic in large LAN segments is toolarge for some NEs. You can divide LAN segments of this type into 2 or more sub-seg-ments to reduce the DCN traffic. To utilize additional network adapters in physically sep-arated LANs, you must either enable the IS-IS routing (see Chapter 4.3.2) or configuremanual routes (see Chapter 4.3.4).

The “Start stack as service” option (MS-Windows NT/2000 only) allows you to startthe OSI stack as a MS-Windows service manager. In this way it can be used by otherservices even if a user has not logged in. The option can only be enabled after success-ful installation of the OSILLC network protocol driver. The stack will start as a servicethe next time the system is booted. It may be started and stopped manually via the ser-vices applet in the Control Panel. The "OpWin Configuration" checkboxes are used tocontrol the start/stop behavior of the "opwin.exe" OSI operator.

The ES-IS button and the Transport button open the dialogs for configuring the ES-IS(see Chapter 4.3.1) and the Transport parameters (see Chapter 4.3.3). The manl.Routes button opens the dialog for configuring manual routes (see Chapter 4.3.4). TheIP-Tunnels button opens the dialog for configuring the OSI over IP tunnel / GRE.

Stack Installation Hints

If the installation requires a reboot, it is strongly recommended to follow the instructions.

If you make an update from a previous OSI Stack version (V 1.7), you may find in theControl Panel / Add/Remove Programs window two installed versions of the OSI Stack(V 1.7 and V1.8).

Don’t uninstall one of them alone, in this case there is no need to uninstall the old one.

iThe OSI stack "osistack.exe" can be controlled by the MS-Windows service manager orby the OSI operator "opwin.exe". These 2 mechanisms are independent from each oth-er.

iWith MS-Windows NT, you must perform a reboot after the OSILLC network protocoldriver installation to achieve a successful registration of the OSI stack by the MS-Win-dows service manager.With MS-Windows 2000, such a reboot is not necessary.

!If the OSI stack is stopped, all established OSI connections will be terminated. It is strict-ly recommended to close all applications which use the OSI stack, before stopping it.The OSI operator is provided to support the service staff.

!The installation procedure will always reset the “Start stack as service” option to the de-fault value

!The installation procedure will always reset the “Start stack as service” option to the de-fault value

⇒ If your computer stops the startup after a reboot and an OSI Stack configurationwindow is open, close it and quit the following message boxes.Confirm the reboot information.

4.3.1 ES-IS Configuration

Fig. 4.2 Configuration of ES-IS

The “Send to default IS” checkbox enables the ES-IS standard routing procedure. Itshould only be disabled if there are problematic or non-standard intermediate systemsin the local LAN which may prevent the establishment of OSI transport connections. Ifthe checkbox was disabled, the “Send to all ES” checkbox must be enabled. Otherwiseit will not be possible to establish a connection.

The “Send to all ES” option enables the establishment of transport connections if thereare no intermediate systems. It is also used if the “Send to default IS” checkbox is dis-abled.

The “Record ES hello” and “Record IS hello” options control the collection of end sys-tem and intermediate system hello PDUs. These data units are used to recognize otherES and IS on the local area network. For a management system, ES hellos do not needto be recorded. IS hellos must, however, be recorded for the “Send to default IS” option!

The “ESI size” and “ISI size” fields determine the ES and IS information size. This isthe number of ES and IS on the LAN, which the stack can save in its internal database.For this reason the values should be greater than the maximum number of ES or ISsending hellos on this LAN.

⇒ If you want to uninstall both OSI Stack versions, don’t forget to remove the OSIProtocol in the network and dial-up configuration window.A reboot is necessary, before you can install a new stack!

⇒ Under rare circumstances, a pop-up warning window “Unable to get windowhandle of OSI stack applet” may open.Confirm by clicking “OK”.

⇒ If you configure the OSI stack of a management application as an IS, you shoulddisable the emission of ES hellos via the “Enable emission of ES hello” op-tion. This is necessary if some NEs with an older Siemens OSI-stack version arein the same routing area with the management application. This older SiemensOSI-stack version is not compatible with the emission of ES hello's and IS hellosfrom the same NSAP address.

A42022-L5901-D53-3-7619 61


OMN:NE-UniGATE

The time interval between two ES hello PDUs, sent by this system, can be controlled viathe “Send ESH all n x 10 sec” edit box. Greater values will decrease the network load,but will slow down the detection of start and shutdown of this end system by the othersystems in the OSI network. In the corresponding ISO 9542 ES hello PDU, the holdingtime is n x 10 x multiplier (multiplier = 3 is not configurable).

4.3.2 IS-IS Configuration

Fig. 4.3 Configuration of IS-IS

The IS-IS configuration dialog can be opened from the main window by pressingCTRL-I. Use of this dialog requires advanced knowledge of the IS-IS routing protocol,as certain settings may lead to problems in the OSI network.

The “Enable IS-IS” option enables the IS-IS routing. If a system is not an IS, it randomlychooses an IS as a standard gateway in the whole LAN. This router IS may not be in thesame area as our ES.

The “Level 2” option changes the stack behavior between Level 1 and Level 2 routing.A Level 1 IS will only collect routing information of its own area and will direct data toother areas via the next Level 2 IS in its own area. If there is no Level 2 IS in an area, itis not possible to send any data out of this area. A Level 2 IS will collect routing data ofits own area and additional information about Level 2 IS in other areas. These IS areable to route data out of an area.

The “Send IIH as designated IS” and “Send IIH as normal IS” edit boxes control theinterval of emission of IS to IS hello PDUs, regardless of whether this system is the des-ignated IS. In the corresponding ISO 10589 L1 or L2 LAN ISH PDUs, the holding timeis n x multiplier (multiplier = 10 is not configurable).

The “Default metric” parameter is used to determine the cost of routes via this system.Higher values lead to higher path costs and will decrease the probability that this systemis used for routing.

The “Priority” parameter controls the priority of different IS so that these may be des-ignated the Level 1 IS of an area and/or the Level 2 IS of a subnetwork. The IS with thehighest priority will become the designated IS. If multiple IS with the same priority arepresent, the IS with the numerically highest MAC address will be chosen.

62 A42022-L5901-D53-3-7619


With the “Enable emission of IS hello” option the emission of IS hello PDUs to endsystems can be enabled or disabled. The time interval between two IS hello PDUs sentby this system can be controlled via the “Send ISH all n x 10 sec” edit box. In the cor-responding ISO 9542 IS hello PDU, the holding time is = n x 10 x multiplier (multiplier =3 is not configurable).

4.3.3 Transport Configuration

Fig. 4.4 Transport Configuration

This OSI stack uses the transport protocol class 4 which is able to detect loss of dataand loss of connections via data acknowledgement PDUs (DataAck). Each data PDUsent must be acknowledged. If a data PDU is not acknowledged after a retransmissiontimer, it will be retransmitted and the retransmission timer is started again. The stack willretransmit a PDU “Retransmission bound” times. If even the last PDU has not beenacknowledged, the connection is terminated.

IS: The use of manual routes in conjunction with IS-IS routing is not recommendedas the manual routes have higher priority. This may therefore lead to problems inthe dynamic routing. However, manual routes may be necessary in order toreach system which do not support dynamic routing or which are located outsideof the routing domain.

ES: Routes, which were established by ES-IS redirection have a higher priority thanthe manual routes. It is therefore possible that a manual route may be used onlyfor the connect request to a network element, but not for data transmission.

A42022-L5901-D53-3-7619 63


OMN:NE-UniGATE

That means that if a NE does not acknowledge, the stack will attempt to establish a con-nection for up to 8 + 16 + 32 + 64 = 120 seconds before informing the requestor that theconnection is broken. This time should be longer than the largest holding time of a helloPDU. This is the only way to ensure that automatic rerouting of the stack will not interrupta connection.

If the stack does not send an acknowledgement PDU for “Window time” seconds, i.e.no data is currently exchanged via this connection, it automatically sends a DataAckPDU to the connected system. This is used to check the state of a connection. If thestack does not receive an acknowledgement PDU for “Inactivity time” seconds, the con-nection will be terminated. Thus a connection loss is detected, even when no data is cur-rently being exchanged. This is the major difference between OSI and TCP/IP stacks.

The “Maximum TPDU size” is the number of bytes which can be transmitted in a singletransport protocol data unit. Larger amounts of data will be segmented. Because an eth-ernet frame can hold approx. 1500 bytes on layer 3 and because this parameter is cal-culated to the power of two, the maximum value which can be used for this parameteris 3 (=1024 bytes).

The “Maximum TIDU size” is used internally at the upper layer 4 boundary and shouldnot be changed.

The “Default lifetime” is a layer 3 parameter but is configured here to simplify use. Thelifetime setting is implemented in order to prevent PDUs from cycling indefinitely throughthe network. For this reason, each PDU sent by this stack starts with the default lifetime.Each hop which forwards this PDU will decrease the lifetime at least by one. This is whythis parameter is often called hop count. If the router which receives the PDU requiresmore than 500 ms to forward it, the lifetime is decreased by one for every 500 ms. Whenthe lifetime reaches zero, the PDU is discarded. The default lifetime must therefore begreater than the number of hops of the longest path in the network. Remember that thelength of a path can increase dramatically in a network experiencing problems.

The “Credit window size” specifies the maximum number of PDUs which this stack al-lows the other side of the connection to send before receiving an acknowledgementPDU. This will increase the performance when receiving large amounts of data via mul-tiple hops (i.e. during software upload). However, a larger credit window size may in-crease the network load and decrease the performance on instable networks. This is

iRetransmission bound = 4 means one original transmission plus 3 retransmissions.The retransmission timer starts with “Retransmission time” milliseconds. If no errorsoccur, the stack will decrease the retransmission timer by dividing it by 2 up to a mini-mum value of 2 seconds. If problems do arise, the stack will increase the retransmissiontimer by multiplying it by 2. For example:

time in seconds Management appl. OSI stack Network element0 Connect ---> Connect request --->8 Connect request --->16 Connect request --->32 Connect request --->64 OnAbort <--- Disconnect request --->64 Disconnect request --->128 Disconnect request --->256 Disconnect request --->

64 A42022-L5901-D53-3-7619


because after the loss of one PDU, it may be necessary to retransmit a number of PDUsup to the value of credit window size.

The “Propose use of checksum” option enables the use of the layer 4 checksum fortransport connections (but only if both sides agree on this). Disabling this option may en-able improved performance, but it also increases the risk that corrupted data PDUs arenot detected.

“Use extended format” enables the use of the extended TP4 format, which mainly al-lows the use of greater TPDU counters, thus causing slightly larger TPDU headers.

The “Enable delayed acknowledge” parameter allows you to reduce the network loadby permitting a connected system to acknowledge multiple TPDUs (received in a certaintime slot) with a single acknowledgement PDU.

4.3.4 Configuration of Manual RoutesManual routes can be used to configure the default IS, to configure different gatewaysfor different address prefixes, to reach systems which do not support the ES-IS protocol,and to use more than one network interface card without enabling IS-IS routing.

4.3.4.1 Manual Routes Dialog

Fig. 4.5 Manual Routes Configuration

This dialog allows you to add new manual routes to the routing table and to remove oredit existing route entries. The Add and Edit buttons open a dialog which allows you toedit the routing information of a single route entry. The Remove button removes the se-lected route from the list box.

The Up and Down buttons allow you to change the priority of the route entries. The firstentry in the list will be the first checked by the stack. If a match between the addressprefix and the destination address is found, the following entries will be ignored.

A42022-L5901-D53-3-7619 65


OMN:NE-UniGATE

4.3.4.2 Add / Edit Route Dialog

Fig. 4.6 "AD Route" Configuration

The stack will compare the “Address Prefix” with the beginning of the destination ad-dresses of network protocol data units. If a match is found, the stack will try to send thedata unit to the “Next Hop” entered in this dialog. The address of the next hop for a giv-en address prefix may be either a Network Entity Title or a Subnetwork Point of Attach-ment (a MAC address). This is configured via the corresponding radio buttons (“NET”or “SNPA” ).

The “Network Interface Card” combo box is used to select the network interface cardwhich is attached to the same subnetwork as the next hop. If the “Bind to Network Inter-face Card” parameter in the main dialog is not set to MULTI, this parameter will be ig-nored!

To configure the default IS, leave the Address Prefix field empty and enter the addressof the default IS as described above. A route entry of this type will be valid for any ad-dress. It should therefore be the last in the list of manual routes in this dialog. It shouldalso never be used in conjunction with IS-IS routing, as this manual default route wouldhave a higher priority than any route in the dynamically created routing table of the IS-ISrouting module.

iIf a complete route is configured (the SNPA of the next hop is used) and this systemcannot be reached in the LAN, the stack will not search for alternative routes and willdiscard any data units where the destination addresses match the address prefix.

66 A42022-L5901-D53-3-7619


4.3.5 Configuration of OSI over IP Tunnel / GRE

Fig. 4.7 Configuration of OSI-over-IP Tunnels

If 2 parts of a DCN network are separated by a pure IP network, the OSI stack can beconfigured to connect these 2 parts with the help of an IP Tunnel or GRE Tunnel. Forthis property, the "Remote IP-Adress" of the source OSI stack and the destination OSIstack must be configured. Once this has been completed, the 2 OSI stacks will negotiatewhat are known as GRE hellos. If there is an additional pure OSI connection betweenthese 2 OSI stacks, also pure OSI hellos will be negotiated. The method which will beused later for transporting DCN information is not determined in this way. The situationis similar to the presence of 2 network adapters. The emission of hello PDUs happensfor ES and IS, but GRE connections are established only for IS. There are 2 differencesto RFC1006 Transport:

OMN:NE-UniGATE

The “Metric” parameter is used to determine the cost of routes via this system. Highervalues lead to higher path costs and decrease the probability that this system is usedfor routing.

4.4 Osiping for MS-WindowsOsiping is a small command line utility which utilizes the ITU-T X.233 echo service tocheck whether a system can be reached on OSI layer 3. The echo service is an optionalfeature of OSI stacks. Osiping may therefore fail to detect a system in the routing domainsimply because this system does not support the echo service.

Osiping has the following command line syntax:

OSIPING [-t] [-n count] [-l len] [-p pat] [-f] [-w timeout] Host-NSAP

The host NSAP address must be entered in hexadecimal digits without spaces. Youmay use network entity titles here (NSAP selector = 00).

iIf a management application sends information to an NE which is connected to 2 net-work adapters over OSI-over-IP Tunnels of this type (Hot standby) , the first availabletunnel will be used to exchange the information. If this path is destroyed, the OSI stackitself recognizes this and switches to the other tunnel. This function is similar to pure OSIconnections.

5 NE-ProxyThe NE-Proxy consists of 3 parts: an MS-Windows NT service (Chapter 5.2), a controlpanel applet for configuration (Chapter 5.3), and a tray operator application to controlthe status (Chapter 5.4).

5.1 Remote LoginNE-UniGATE supports remote login from an external computer via TCP/IP using anNE-Proxy. The NE-Proxy runs on a separate computer in the company intranet, that pro-vides access to the OSI net as well as to the TCP/IP. The NE-Proxy converts connectionrequests and data packets from TCP/IP into OSI and vice versa.

The NE-UniGATE software on the external computer uses the NE-Proxy driver insteadof the network driver. Using both drivers simultaneously is not possible.

The connection of the external and internal computers via TCP/IP is organized using thestandard mechanism of MS-Windows. Both LAN connections and dial-up connectionsare supported. If the connection between the external and the internal computers is rout-ed via a public network like the Internet, a well administrated firewall router should pro-tect the NE-Proxy from unauthorized access.

Fig. 5.1 Remote Login Scenarios

Fig. 5.1 shows a possible NE-Proxy scenario. External operator #1 uses a dial-up con-nection provided by an Internet service provider to connect the NE-Proxy via the Inter-

A42022-L5901-D53-3-7619 69


OMN:NE-UniGATE

net. This connection is protected against unauthorized access by a firewall router.External operator #2 uses a dial-up connection via a dial-up service provided by the tele-com company itself (e.g. MS-Windows NT remote access service). The NE-Proxy actsas a gateway between IP and OSI LAN. All operators are connected to a gateway NEthat routes OSI packets to the other NEs via DCC channels.

It is not necessary to have a dedicated machine for every service, e.g. it is also possibleto run the dial-up service, the NE-Proxy service and one internal operator on the samemachine.

5.2 ServiceThe NE-Proxy service is a background process that can run on an MS-Windows NT ma-chine without a user logged in. Like any other service, it is controlled by the MS-Win-dows NT service control manager. The service control manager window is opened bychoosing <Start> <Settings> <Control Panel> <Services>. The following window(Fig. 5.2) allows you to monitor the NE-Proxy status and to start or stop the NE-Proxyservice.

Fig. 5.2 Services Window

The NE-Proxy service does not require parameters. It cannot be paused or continued(these two buttons are disabled). The startup mode can be configured by pressing the<Startup> button. The following window (Fig. 5.3) appears:

70 A42022-L5901-D53-3-7619


Fig. 5.3 Service Window

The preferred startup type for the NE-Proxy service is "Automatic". This ensures that theservice is started after booting the machine. The service should run with system ac-count. The "Allow service to interact with desktop" option must be enabled to allow theservice to send status update messages to both the control panel applet and the trayoperator.

The NT administrator may not allow all users to start, stop, or configure the service.

5.3 Control Panel AppletThe NE-Proxy control panel applet allows you to configure the NE-Proxy service. It isdivided into 4 property folders. The NT administrator may prevent particular users fromconfiguring the NE-Proxy service. In this case, only the "General" folder (Fig. 5.4) is dis-played.

Maximum Number of Clients

The NE-Proxy service can serve up to 50 client connections. Using this option, the num-ber of clients that can be connected at a time can be limited to a lower value.

Maximum NE Connections per Client

The NE-Proxy service can serve up to 150 NE connections per connected client, as longas the overall NE connection limit is not reached. Using this option, the number of NEconnections per client can be limited to a lower value.

Maximum NE Connections at all

Displays the non-configurable value "150".

TCP/IP Port

The NE-Proxy service looks for clients on a specific TCP/IP port. The port numbershould be different from the port number used by other services (e.g. file server, webserver etc.). The default port number is 3012.

74 A42022-L5901-D53-3-7619


Local NSAP Address

The local NSAP address identifies the host in the OSI TP4 network. It should be uniquein the network. The "OSI Control Applet " button opens the OSI control panel applet toconfigure the local NSAP address.

Local T-Selector

The local T-Selector identifies the NE-Proxy service on the OSI transport layer (similarto a TCP/IP port). It should be a unique string of 1 to 16 characters. Because differentclients must have different selectors, the NE-Proxy appends the client ID to the selector(e.g. "TS" + Client #1 = "TS01"). Therefore the maximum input size is 14. The NE-Proxyuses different selectors for QD2/QST connections and Q3 connections.

Local S-Selector

The local S-Selector identifies the NE-Proxy service on the OSI session layer. It shouldbe a unique string of 1 to 16 characters. Because different clients must have differentselectors, the NE-Proxy appends the client ID to the selector (e.g. "SS" + Client #1 ="SS01"). Therefore the maximum input size is 14. The S-Selector is used for Q3 con-nections only.

Local P-Selector

The local P-Selector identifies the NE-Proxy service on the OSI presentation layer. Itshould be a unique string of 1 to 4 characters. Because different clients must have dif-ferent selectors, the NE-Proxy appends the client ID to the selector (e.g. "PS" + Client#1 = "PS01"). Therefore the maximum input size is 2. The P-Selector is used for Q3 con-nections only.

Enable Connection Supervision for TCP/IP

The "TCP/IP Connection Supervision" feature allows to check all network elements con-nected via TCP/IP for their presence. This check is performed by regularly sendingICMP echo requests (ping) to the network elements.

Ping Interval

The "Ping Interval" field allows to specify the interval in seconds, after which ICMP echorequests (ping) are to be sent to network elements.

Ping Timeout

The "Ping Timeout" field allows to specify the timeout in seconds, after which an ICMPecho request (ping) sent to a network element is treated as failed, if there is no re-sponse.

Ping Attempts

The "Ping Attempts" field allows to specify the maximum number of ICMP echo requests(ping) to be sent, in case of no response.

Enable Keep Alive for all TCP/IP Connections on your computer

With this function enabled, packets are exchanged via the TCP/IP connections at regu-lar intervals, even if there is no information to be reported. This allows a loss of connec-tion (e.g. because of an NE failure) to be detected at an early stage.

A42022-L5901-D53-3-7619 75


OMN:NE-UniGATE

If this function is disabled, NE-UniGATE does not receive an alarm in case of a loss ofconnection. As a result, NE-UniGATE cannot detect this type of fault until the user triesto configure the NE or to request alarms explicitly.

Time (s)

The “Time” field allows to specify the time between two requests. This parameter shouldbe greater than the product “Interval (s)” x “MaxDataRetransmission”.

Interval (s)

The “Interval” field allows to specify the time out period for the request.

MaxDataRetransmission

The “MaxDataRetransmission” field allows to specify the count of retries.

Welcome Message

The NE-Proxy can send a welcome message of max. 255 characters to the client, whenthe client opens a session. This message may be displayed at the client before the login.

76 A42022-L5901-D53-3-7619


Write Connection Log

Mark this check box to write all client connections, login attempts and network elementconnections to a log file. The log file has the name NEProxy<Timestamp>.log and is lo-cated in the NE-Proxy installation directory.

Request Clients to login

Mark this check box to request a client login. This prevents unwanted access and shouldonly be disabled if the NE-Proxy is used in a secure environment (company intranet).

Add User

Opens the user dialog for specifying user name and password.

Change Password

Opens the user dialog for specifying the old and the new passwords.

Delete User

Removes a user from the list after asking for confirmation.

5.3.5 Add User / Change Password Dialog

Fig. 5.8 User Dialog

User Name

The user name must be 1 to 15 characters long and must be unique. An error messagebox is displayed if the user name is already in use. In the case of the "Change Pass-word" command, the current user name is displayed read-only.

Old Password

The password must be 1 to 16 characters long. In the case of the "Add User" command,this field is inactive.

New Password

The password must be 1 to 16 characters long.

iNote:If the NE-UniGATE “Delete NE-User” attempt is applied to an NE for one’s own loginuser-ID while the NE was connected using that user-ID and password, the transactionshows “Failed”, but there is no such message in the “Notifications” window.

OMN:NE-UniGATE

Retype Password

The password must be 1 to 16 characters long, and must be identical with the new pass-word.

5.4 Tray OperatorThe tray operator should be launched from the MS-Windows "Autostart" group. It checksthe status of the NE-Proxy service and adds a small icon (Fig. 5.9) to the system trayarea of the MS-Windows task bar. The icon shows whether the NE-Proxy service is run-ning or stopped. If the user moves the cursor over it, the service name and its currentstatus are displayed. If the user double-clicks the icon, the control panel applet (seeChapter 5.3) is opened.
