Page 9: Introduction
Introduction 1.1 The Router Module The Router module is a component of the Series 8000 range of X.25 switches. It provides an IP Routing function which allows transparent routing of IP frames between the local Ethernet network and remote IP Ethernet networks via a Series 8000 network.
Page 10: Ip Routing
1.2 IP Routing IP Routing deals with Internet Protocol (IP) packets, which are the most common type of LAN network layer packets. IP is part of the TCP/IP protocol suite. IP Routing in Router allows IP packets to be transparently passed across the X.25 network to remote Ethernet LAN networks, using Series 8000 X.25 PSEs to provide the transport medium.
Page 11: Typical Ip Routing Application
NETWORK NETWORK 1.0.0.0 2.0.0.0 HOST 1 HOST 2 X.25 ROUTER 1 ROUTER 2 Network ROUTER 3 ALIEN NETWORK ROUTER 3.0.0.0 HOST 3 NETWORK 4.0.0.0 HOST 4 Figure 1-1 Typical IP Routing Application In order to route IP packets originating on Ethernet network 1.0.0.0 to a destination on Ethernet network 4.0.0.0, Router 1 will on receipt of a packet from the LAN addressed to network 4.0.0.0 examine its routing tables.
Page 12 new call will be made to the X.121 address of Router 2 before the data can be sent. On receipt of the IP packet, Router 2 will examine its routing tables, which should allow it to forward the packet to the ''next hop'' router on Ethernet network 2.0.0.0 en route to its final destination.
Page 13: The Gateway Function Of Router
1.3 The Gateway Function of Router A user on either X.25 or Ethernet can make a connection to a service on either network via a single call from a terminal; this is commonly known as a 'seamless connection'. Figure 1-1 shows a typical application of the gateway function of Router, allowing X.25 terminals to access host computers connected to an Ethernet LAN.
Page 14: Multiple Sessions
1.4 Multiple Sessions In some circumstances it would be advantageous to allow an operator at a terminal to change between two or more applications, or services, at the press of a key. For example, a sales desk may require quick access to Sales Order Processing, Stock Control, and Electronic Mail services.
Page 15: Services
1.5 Services Router has two basic types of service: WAN Services and LAN Services. Router Services describe the address of the service, an optional password, and connection characteristics (via profiles). Each service has a name which can be employed by users to connect to their required destinations. •...
Page 16: Profiles
1.6 Profiles Profiles are used within Router to define sets of characteristics that should be applied in given circumstances. There are three types of profile: a User Profile that describes the characteristics to be applied to a user, a Service Profile that describes the characteristics of a connection to a service, and a Terminal Profile that describes the characteristics of a manager's terminal.
Page 17: Installation
Installation This chapter is provided as a supplement to the full installation guides for Series 8000, knowledge of and reference to which is assumed throughout. 2.1 Hardware Description The Router software can be loaded onto one of two hardware variants: the TGate/Router card for use within the 8325 card frame, and the TGate/Router module for use in either the 8425 or 8525 card frame.
Page 18: The 8425/8525 Tgate/Router Module
The only indicator is a green LED, serving as a 'heartbeat', blinking at a rate dependent upon processor utilisation. The TGate/Router card displays real-time status information via the 8325 display/control panel, in line with other 8325 cards (see Chapter 7 of the 8325 Installation Guide).

2.3.2 8425/8525 Module The following subsections outline the procedure for inserting and removing modules from 8425/8525 systems. 2.3.2.1 UPM4 and TGate/Router (Main Modules) The main modules are accessed by either opening the front door (8425) or by unscrewing the five captive screws on the front door in the centre section of the unit (8525).
Page 23: Lpim Installation And Removal
2.4 LPIM Installation and Removal Live insertion of LPIM modules is not possible. Prior to installation, the TGate/Router card (8325) or PAM (8425/8525) must be removed (see Section 2.3). 2.4.1 LPIM Installation Before installing the LPIM the port must be selected by moving the links to the positions shown in black in the relevant section of Figure 2-4.
Page 24: Cabling
2.5 Cabling 2.5.1 AUI Port The AUI interface provides a standard 15-way D-type female connection. The pinout is defined in Appendix A.4. The TGate/Router AUI port provides 15 VDC (8325) or 12 VDC (84/8525), current limited to 500 mA, on circuit VP. The AUI port does not provide the normal slide locking for securing the cable;...

Page 27: Initial Configuration
Initial Configuration This chapter summarises the tasks that need to be carried out when initially configuring Router. Tasks that are not fully described here, are described in Chapter 4. An example configuration is given in Appendix E. 3.1 Control Panel Displays On the 8325 control panel, the TGate/Router has a board ID of and only uses the first character in its 'Display Status' field.
Page 28: Installing The Application
3.2 Installing the Application Using the Series 8000 Node Manager, select the Utilities menu and then the Install Application menu. When you first enter the screen it lists all the applications. An asterisk (*) in the In Use column indicates that an application has been selected for loading onto one or more slots.
Page 29: Creating The Router Port
3.3 Creating the Router Port Next, a logical port (with a number 7000-7999 inclusive) must be created for Router to use (for example this could be 7050 to indicate that Router is running in slot 5). Configure the X.25 network level and user facilities as required, and bring the port online.
Page 30: Initial Configuration Commands
3.4 Initial Configuration Commands After cold start, Router is placed in an initial state ready for configuring, with the default configuration defined in Appendix B. Cold start normally only takes place when the card is first installed. However, if at any time it is found necessary to go back to the default configuration, then a cold start can be performed by deleting the configuration files from disk B (see...
Page 31 General configuration. Manager password, manager conf gen terminal type and slot number. Protocol configuration. IP address. Other fields can be conf prot left as defaults, unless you are familiar with TCP/IP and wish to optimise these parameters to match your network.
Page 32: Manager-Defined Terminal Configuration
3.5 Manager-Defined Terminal Configuration When a user logs on after a cold start, Router requests selection of a Terminal Type. Option 5 of the menu allows the terminal characteristics to be defined to match the terminal in use. This is only necessary if you are not using one of the predefined terminal types.
Page 33: Manager Procedures
Manager Procedures 4.1 Overview System management is carried out by a supervisor or network manager. The Router software manager facilities (referred to briefly as the 'manager') provide the dialogue between the supervisory/managerial user and Router. It is an intelligent, command-driven, menu/form based system, and provides the ability to configure, monitor, and control Router.
Page 34: How The Manager Works
4.2 How the Manager Works 4.2.1 Input Input to the manager is simple. You enter the command or information as an ASCII string, then terminate and submit it for evaluation by entering carriage return or line feed. The editing functions available are: Deleting a Character When a delete ( ) or backspace (...
Page 35: Using Menus
When a command is processed, any additional information required is prompted for, and if the prompt has an associated menu then the new menu will be displayed with the prompt. Menus are only changed when it is necessary to assist and prompt the user in the selection of commands, actions, or items.
Page 36 Router uses standard form handling throughout. There are several types of field found in a form: Constrained List, Free Format Text, Free Format Blind Text, and Information Only fields. The Constrained List is a list of valid entries for the field, e.g. a directory banner field may only contain ENABLE or DISABLE.
Page 37 Restore ( – Restores the field to its current configuration state (or initial state). Space – When the cursor is at a Constrained List, the list is sequenced forward one item. Backslash ( – When the cursor is at a Constrained List, the list is sequenced backward one item.
Page 38: Initial Entry To The Manager
4.2.5 Initial Entry to the Manager After connecting to Router, you can gain entry to the manager by using the command. Once you are logged on, the manager assumes it is logon communicating with a terminal of the type configured as the 'manager terminal type'.

A positive response can be indicated in several ways: TRUE ENABLE A negative response is indicated using the inverse of these: FALSE DISABLE...
Page 100 <Name> (<ServiceName>, <ProfileName>) A name is an ASCII name from one to fifteen characters. All names must start with an alphabetic character (A-Z). All letters are not case- significant, but are stored in the correct case for visual clarity. Names can be used to identify Services (LAN and X.25) and profiles (USER, SERVICE, and TERMINAL).
Page 101 <TCP port> A TCP port is a number in the range 0 to 65535 (16 bits). The port refers to a logical device within a physical device (Internet Address). This number is often translated into a service, e.g. 23 is commonly used for the TELNET service on hosts that support TCP/IP.

Page 103: User Procedures
User Procedures This chapter is self-contained. It provides instructions for every-day users of Router's gateway facilities. 5.1 The User Environment A connection to a service is called a session. You are given the ability to hold more than one session simultaneously. You cannot communicate with all sessions simultaneously, but you can switch between them with ease.
Page 104: User Input

5.2 User Commands 5.2.1 Command Specifications The following explanation will help you to understand the specifications of the commands that are available to you, all of which are described in the subsequent subsections. When you submit an entry line with etc, then the line is subject to RETURN the following evaluation:...
Page 106 The following commands are available to you. They include the ability to make/break connections, gain status information, and obtain help. Make connection commands: CALL CONN OPEN SESSION Break connection commands: DISC CLOSE QUIT LOGOFF Status/configure commands: STATUS Helpful commands: HELP DIRECTORY CATALOGUE Ancillary commands:...
Page 107: Call/Conn/Open
5.2.2 CALL/CONN/OPEN These commands allow you to establish a connection to a service. <InternetAddress> <TcpPort> CALL <ServiceName> <ServiceName> CONN OPEN <X.121 Address> W = only available to WAN users connecting to LAN. L = only available to LAN users connecting to X.25. Prior to connection, if a password has been set on the selected service, you are requested to enter it.
Page 108: Disc/Close
5.2.3 DISC/CLOSE These commands allow you to disconnect either the last session used, or a specified session by its SessionId. DISC <SessionId> CLOSE The session is disconnected and you are then presented with a disconnection message. You will stay in dialogue. X870-300351 Issue 1 Rev.0...
Page 109: Quit/Logoff
5.2.4 QUIT/LOGOFF These commands terminate all sessions and disconnect you from Router. QUIT LOGOFF You are not presented with disconnection messages for each session. The WAN or HOST to which you are attached sends you an appropriate message. X870-300351 Issue 1 Rev.0...
Page 110: Session
5.2.5 SESSION This command allows you to enter communication with the last session used, or with a specific session. SESSION <SessionId> You go directly into communication with the session selected. In general it is preferable to switch sessions using 'hot-keys'. X870-300351 Issue 1 Rev.0...

Page 113 occasion. This option has no effect when executed from a LAN user; it is only relevant in the case of a WAN user calling a TELNET service. The REFRESH string is sent to the service when a session is reselected. In some applications it is possible to request that your screen is updated (refreshed).

Page 125: Ethernet, Tcp/Ip And Rip
Appendix C Ethernet, TCP/IP and RIP This appendix contains brief descriptions of Ethernet Local Area Networks, TCP/IP and RIP. They are introductory and are provided as additional information. It is not necessary to understand these systems to make use of the Series 8000 TGate successfully, and this appendix may be ignored if desired.
Page 126: C-1 Ethernet Topology
The CSMA/CD type of MAC is 'probabilistic' or 'non-deterministic'; this is because the ability of any one station to transmit information has a probability corresponding to the activity on the bus and the nature of that activity, thus preventing the pre-determination of performance or propagation delays for any given station on the network.
Page 127 The IEEE standard allows the use of good quality coaxial cable ('yellow cable') or a thinner cheaper coaxial cable (RG58). These are known as Ethernet IEEE 802.3 10BASE5 and Thinwire Ethernet IEEE 802.3 10BASE2 (Cheapernet). Thinwire Ethernet has the disadvantage of reduced distance from 500 metre segments to 185 metre segments, and a maximum number of nodes (taps) per segment from 100 to 30.
Page 128: Tcp/Ip Protocols
C.2 TCP/IP Protocols TCP/IP is currently the de facto standard for LAN interworking. It was developed by researchers within and around the Advanced Research Projects Agency (ARPA) in the United States. It is currently the most popular non-proprietary protocol in use today. TCP and IP both refer to specific protocols within a complete suite of interworking protocols known as the 'Internet Protocol Suite';...
Page 129 The Internet Protocol (IP) layer is the common networking and inter- networking layer within the TCP/IP protocol suite. This allows a standard carrier network to deliver 'datagrams' independent of the higher layer protocols (applications), and conversely it allows an application to communicate without any knowledge of the underlying media/network.
Page 130 character set may be different (e.g. IBM-EBCDIC), without requiring different terminal equipment. FTP is a File Transfer Protocol; it allows the transfer of ASCII or IMAGE files from one machine to another across the network. Again the use of ASCII allows a common interchange to take place, even if the hosts have different character sets.
Page 131: Ieee 802.3 And Ethernet Differences
C.3 IEEE 802.3 and Ethernet Differences In September 1980, Digital, Intel and Xerox (DIX) published 'the blue book' Version 1.0: A Local Area Network, Data Link Layer and Physical Layer specifications. It was later revised as Version 2 in November 1982. Version 2.0 stated that it was an interim specification and the Ethernet Specification would now evolve with the Standards bodies (IEEE).
Page 132 DIX defines that frames contain a 2-byte type field as opposed to a 2-byte length field in the ISO/IEEE specifications. The addressing parts of the frame are identical in both the IEEE and DIX specifications. The type field has the advantage of using the same cabling for efficiently operating many different protocol sets (e.g.
Page 133: Rip
C.4 RIP Router implements the Routing Information Protocol (RIP) in order to propagate routing information throughout the network. The protocol is a straightforward implementation of vector-distance routing for local networks that partitions participants into active and passive (silent) machines. Active routers advertise their routes to others; passive machines listen and update their routes based on advertisements, but do not advertise.
