Preface

READERSHIP OF THIS MANUAL

This manual is written for the person who is responsible for the connection of terminals tothe Bull DPS 7000 system or, through the Communications Network Software (CNS7)over a DSA network, to other network end users.

The manual should be read prior to generation of the CNS7 terminal managementsoftware, in order to decide what modes of use will be adopted for the terminals in thenetwork, as well as any other characteristics which need to be declared at the generationstage. This manual is, therefore, not intended for terminal operators, but rather as a basisfor the creation of the "secondary" network - as such, this manual should be used inparallel with the System Generation manual.

STRUCTURE OF THIS MANUAL

Section 1 gives a general introduction to the terminal managementsoftware of CNS7.

Section 2 gives the basic connection procedures.

Section 3 describes the common secondary dialogue for conversationalterminals.

Section 4 gives procedures specific to Asynchronous terminals.

Section 5 gives procedures specific to Videotext (Minitel) -typeterminals.

Section 6 gives procedures specific to QUESTAR/T, QUESTAR/400and VIP Synchronous terminals.

Section 7 gives procedures specific to IBM BSC 3270 terminals.

Section 8 gives procedures specific to receive-only terminals (typically,printers).

Section 9 gives the procedures specific to IBM BSC 2780 terminalsoperating in connection with the GCOS 7 operating system.

CNS7-A1 Terminal Management Reference Manual

iv 39 A2 43DM Rev01

Section 10 gives details specific to GCOS 7 access.

Section 11 gives details of access to other systems in a DSA network.

Appendix A gives an introduction to terminal models which are predefined("standard") in the software.

Appendix B describes asynchronous terminal models.

Appendix C describes synchronous terminal models.

Appendix D gives details of secondary dialogue commands andmessages.

CONVENTIONS

In command format statements used in this manual the following conventions apply :

Brackets [ ] Enclosing keywords, parameters or numericalvalues imply that these items are optional to thecommand and may be omitted.

Braces {} Indicate that a choice should be made betweenthe parameters enclosed.

Character # Indicates a blank character (space).UPPER CASE Is used for keywords and they should be keyed

in as such.Angularbrackets

< > Enclosing upper case characters imply thatthere is a key on the keyboard having thosesame characters.

Enclosing lower case characters imply that thecharacters themselves should not actually bekeyed in, but that they represent the type ofdata to be input.

However, a request such as : key means press and

simultaneously.

Lowercaseletters

(e.g., id) indicate a symbolic variable whoseexact value must be supplied by the user.

Invertedcommas

" " Indicate a minitel key.

1. Introduction

This manual describes the terminal management software of the CommunicationsProcessor Software (CNS7). The information must be used together with thedocumentation describing the specific features of each terminal, which is usually providedwith the terminal itself.

As the characteristics of the terminal and the way in which it is to operate must bedeclared during the generation phase of the CNS7 software, this manual should be usedas a preparation for the generation of the terminal management software. It may also beused in the preparation of end-user documentation for the specific application and use ofterminals connected to a OSI/DSA system or network through CNS7.

1.1 ENVIRONMENT

CNS7 is the software of the network processors which are integrated into a Bull DPS7000 system. Its main functions are those of a front-end processor; concentratingterminals for connection to the Bull DPS 7000 host system, and to act as a network front-end processor - allowing inter-system communications over a OSI/DSA network. It alsohas message switching and routing capabilities.


1-2 39 A2 43DM Rev01

1.2 TERMINALS SUPPORTED

The terminals supported include all the current Bull range of terminals and some terminalsmanufactured by other companies. Two basic uses of terminals are supported:

• Conversational use in dialogue with an application located on the local Bull DPS 7000system.

• Conversational use in dialogue with other applications or terminals located elsewhere inthe DSA network to which the local system is connected.

The terminals are also classified according to their technical characteristics, as follows:

• Asynchronous• VIP• 3270 BSC• 2780 BSCCertain generation directives must be defined to identify the different terminal types whichcan be connected (See the CNS7 System Generation manual). A list of predefinedstandard models and their characteristics is given in Appendix A of this manual.

1.3 TERMINAL MANAGER

The Terminal Manager (TM) is a part of the CNS7 operating system software. It ensuresthe concentration function, enabling many different terminal types to use the applicationsavailable on the network.

The TM is also part of the front-end function of CNS7. It translates application data to theformat adapted to the terminal, taking full advantage of the features available on theterminal.

The TM personalizes data to conform to the options selected during configuration ofCNS7 or by a local dialogue with the TM (Secondary Dialogue Commands).

The purpose of this manual is to describe how a terminal can take full advantage of theapplications and services available on a network. The commands provided by which theTM can control a terminal are explained, together with the relationship between theavailability of TM facilities and system configuration.

1.4 SECONDARY NETWORK

The secondary network is the network between the terminal and the Terminal Manager. Itmay include switched or private lines, used in asynchronous or synchronous mode. Thesecondary network may also provide access via an X.25 network using a PacketAssembly Disassembly facility (PAD/VIDEOPAD) or a specific concentrator (TCS, DCU...)

Introduction

39 A2 43DM Rev01 1-3

1.5 HOST SYSTEMS

Except for network operators, the terminal users connect to applications or subsystemslocated on a host system. Note that these systems are usually restricted as to whichterminal types and models may be connected.

The following hosts are supported:

Local host system (Bull DPS 7000)

• GCOS 7 Operating System• Interactive Operator Facility (IOF)• Transaction Driven System (TDS)• Cobol Message Control System (MCS)

Remote systems, accessed via a OSI/DSA network:

Bull DPS 7 or Bull DPS 7000

• GCOS 7 Operating System• Interactive Operator Facility (IOF)• Transaction Driven System (TDS)• Cobol Message Control System (MCS)

1.7 GENERATION

The CNS7 configuration is described by means of a file usually referred to as the CONFIGfile. This file can be built either manually, using the Node Generation Language (NGL) or


1-6 39 A2 43DM Rev01

by the FPG 7 interactive program (for GCOS 7 applications only). The file is composed ofdirectives which describe CNS7 objects. The objects are linked to define the networktopology and all functions of CNS7. A description of the objects relating to the terminal(s)and examples of how these objects are interrelated are given below. For furtherinformation refer to the CNS7 NGL manual.

N.B. For the definition of the various terms, interfaces and protocols used in the followingtext (eg. PAD, X3, X28 ...etc) refer to section "SOME DEFINITIONS"(previous section).

Mailbox (MB)

The Mailbox (MB) object identifies a correspondent uniquely on a particular system. Thecorrespondent is either a terminal or an application. It is an addressable end-point of thelogical connection between two correspondents.

The mailbox name is part of the Standard Global Mailbox Name. The Standard Globalmailbox name identifies the correspondent uniquely in a network.

Two types of MB are possible (for terminals): the station mailbox (MB-STAT) which isdirectly associated with a station (SN-TMG) and the TMG mailbox (MB-TMG) which mustbe used with the mailbox extension (TX-TMG).

The Standard Global Mailbox name for a mailbox type STAT is:

Session Control-identifier (Sc-id) of the system.

The Standard Global mailbox name for a mailbox type TMG is:

Session Control-identifier (sc-id) of system plus mailbox name plus mailbox extension.

Mailbox Extension (TX)

The Mailbox Extension (TX) is the part of the Standard Global Mailbox Name. Itreferences the mailbox extension name, the name of the maibox of type TMG (MB-TMG),the name of the SN object addressed via this extension and (if applicable) the name ofthe Network Route (NR) object for accessing X.29 applications or PAD terminals (see SNand NR object description, below).

Introduction

39 A2 43DM Rev01 1-7

Terminal Station (SN)

The Terminal Station (SN) object represents a logical terminal station. It comprises one ormore Logical Devices (LD) and is the entity seen by the application, for communicationpurposes. The station may comprise one or several of the following:

• a device,

• a pool of devices,

• part of the resources of a device,

• part of the resources of a pool of devices.

The Terminal Station (SN) is addressed across the primary network by the session controlidentifies (sc-id), a Mailbox (MB) and Mailbox Extension (TX) (Standard Global DSAName). It may have more than one network address.

Connection Descriptor (CD)

A Connection Descriptor (CD) defines the connection phase. It specifies default values forthe security parameters which must be provided at connection time and specifies whetherthe security parameters must be entered manually by the operator or automatically byCNS7.

The CD may be mapped from several Terminal Stations (SN's) in order to define thesame connection procedure for all Terminal Stations.

The CD may also be mapped to a Correspondent (CO) object in order to specify a defaultcorrespondent to which the terminal station will be connected.

Correspondent Object (CO)

The Correspondent Object (CO) represents a correspondent in the network. Thecorrespondent is either an application program that the terminal operator is accessing oranother terminal.

The CO associated with terminals:

• CO-TMG, used for DSA correspondents. The object is used to convert a symbolicname entered by the operator into the Standard Global DSA Name of thecorrespondent.

Logical Device (LD)

The Logical Device (LD) object is a "virtual" view of a Physical Device (DV) or Device Pool(DP). LD is used to define one element of a Terminal Station (SN).

One SN object may be mapped to several LD's (for example if the terminal stationcomprises several devices) and several LD objects may be mapped to a single DV or DP(for example if several terminal stations share the same device or pool).


1-8 39 A2 43DM Rev01

Device (DV)

The Device (DV) object represents a physical device (terminal, printer etc..) on thesecondary network or some process emulating a real device. Its parameters include aphysical description of the device and some parameters which define the behaviour of theTM.

The DV object contains data used by TM to control use of secondary network servicesand to store status information received from these services. The DV object acts as anaddressable end point on the secondary network. The DV object may be mapped fromone or more Logical Devices (LD) from more than one station. The DV object may map toone Terminal Unit (TU) object, or to one Logical Line (LL) object (see description of TUand LL objects, below).

The DV object must be mapped to an MD, which may contain some parameters notdeclared on this DV (see description of MD below).

Model Object (MD)

The Model object (MD) provides the parameters of a device. The parameters will be usedby all DVs mapped to this MD. Some of the MD parameters are also present in the DVobject. The parameters on MD are used as default values if the parameters are notoverridden on DV. Every DV must be mapped to an MD object.

A list of standard MD objects which correspond to standard devices supported by CN 7can be found in Appendix B and C of this document. A list of standard devices (or models)which are cross referenced to standard MD is shown in Appendix A.

If a device is in the list of standard MD objects (shown in Appendix B or C), only the MDobject (without its parameters) need be declared at generation.

Login Descriptor (LN)

A Login Descriptor (LN) defines the login phase. It specifies the default values for thesecurity parameters which must be provided at login and specifies whether the securityparameters must be entered manually by the operator or automatically by CNS7.

The same LN may be mapped from several DV objects in order to define the same loginprocedure for several devices.

User Descriptor (UD)

The User Descriptor (UD) object provides a way to retrieve the login descriptor (LN) andconnection (CD) descriptor specific to a terminal operator. If the operator enters the nameof a UD in the login command (user descriptor parameter of the login command), CNS7will use, by default, the LN and CD directives mapped from this UD.

In order to personalise the Login command, the UD object could be given the name of theterminal operator who will use it.

Terminal Unit (TU)

The Terminal Unit (TU) object represents a physical workstation which is a group ofdevices (e.g. a screen terminal with a printer). It is generally used for VIP and TGX

Introduction

39 A2 43DM Rev01 1-9

devices (for example, a VIP7700 controller), but is also used for VIP7801 and VIP7802asynchronous units.

Device Pool (DP)

A Device Pool (DP) represents a set of devices from which the first available device isselected at session establishment and then re-selected during the session, according toits availability.

A DP may be shared by many Logical Devices (LD) among multiple sessions. This type ofpooling only applies to the output flow from TM to the terminal. The attributes of the poolmust be supported by all its DVs either directly or through emulation.

Cluster (CL)

The Cluster (CL) object may represent terminal cluster controllers or specific transportlayers in CNS7.

When used to represent terminal cluster controllers, the object indicates the physicaladdress of the cluster and is used for group polling VIP/3270 terminals.

When used to represent a specific transport layer in CNS7, it indicates parameters forflow control, retries etc. and is used only for synchronous terminals communicating acrossan X.25 network.

Logical Line (LL)

A Logical Line (LL) represents the link control entity in the local system. It is the end pointof a link connection. The object type indicates the line protocol used (i.e. LL-ASY forasynchronous devices, LL-BDL used for HDLC lines using LAPB protocol).

Physical Line (PL)

A Physical Line (PL) object represents the line adapter (or communications adapter) towhich the communications line is connected. The line adapter is a hardware componentfitted to the communications controller board.

Controller (CT)

A Controller (CT) object represents a hardware communication controller. It specifies thehardware address of this component.

DEVICE macro

The DEVICE macro is used to simplify the CONFIG. file. It automatically generates thefollowing objects:

MB-STATSN-TMGLD-TMGDV-type


1-10 39 A2 43DM Rev01

NOTE: The DV-type (e.g. DV-ASY, DV PAD) is given by the MACRO DEVICE type.

PROFIL

The PROFIL directive defines the parameters for PAD devices. These parameters are inaccordance with the X.3 recommendation of the CCITT and override the values defined atsubscription time (see Section "SOME DEFINITIONS" for descriptions of PAD, X.3 andCCITT).

Network Route (NR)

The Network Route (NR) object defines the route out of the system, towards an externaldestination. This destination may be:

• a PAD device,

• a cluster of synchronous devices on an X.25 network,

• a remote system.

Network Subscription (NS)

The Network Subscription (NS) object gives the necessary parameters (e.g. HDLC orX.25) to establish a connection across a network .

Introduction

39 A2 43DM Rev01 1-11

1.8 LOGICAL CONFIGURATION

The logical configuration of a device describes how the device is accessed by acorrespondent and how the terminal operator may connect to an application. Simplifiedexamples of logical configuration, are given in the following paragraphs. Reference shouldbe made to section "GENERATION" for explanations of the various objects (CO, CD, LNetc ). For more detailed explanation refer to the CNS7 V4 NGL manual.

N.B.: In figures 1-2 through to 1-6:

1) The legends in the boxes indicate the family name, the object name and the objecttype (in brackets).

Example:

MB : Mailbox family

MB1 : MB1 is the object name

(TMC) : TMC is the object type.

2) The arrows indicate the mapping direction.

Example:

An arrow from a DV object pointing to an MD object indicates that the DV maps tothe MD.

If the errors are in both directions between two objects this indicates that the objectsare mapped to each other .

Example:

A CD is mapped to a CO; and the CO is also mapped to the CD.

1.8.3 One Terminal Unit Connected to Two Different Applications.

One Terminal Unit can be connected to two different applications (C01 or C02) as shownin figure 1-4. Note that the Device Object (DV1) is connected to two different LogicalDevices (LD1 and LD2) and that only one Login Descriptor (LN) is used.

1.8.4 Pooling of Devices

Several devices can be grouped in a pool by mapping a Device Pool (DP) object betweenthe Logical Device (LD) and Device (DV) objects (see figure 1-5). This configuration has anumber of advantages (over devices which are not pooled), for example:

1. When a correspondent opens a session, the TM selects the first device available,thus if one device is not serviceable the TM will select the next available device.

2. The number of objects to be declared is reduced.

2. Connecting your Terminal

The connection can be broken down into 3 phases (see figure 2-1):

• the physical connection of the terminal,• the connection of the terminal to the Terminal Manager (TM) using the LOGIN

command,• the connection of the terminal to an application using the CONNECT command.

These three phases can be automatically performed as soon as the terminal is switchedon, if it has been provided for in the generation directives.

The physical connection phase is described in this section.

The connection of the terminal to the TM using the LOGIN command (Login phase); andthe connection of the terminal to an application (logical connection) are accomplished withthe Secondary Dialogue described in Section 3.

2.1 CONNECTING A TERMINAL THROUGH SWITCHED OR DEDICATEDLINES

The procedure for connecting to CNS7 by a dedicated or a switched line is describedbelow (see figure 2-2):

1. Set the power switch of your terminal to "on".

2. Set your terminal to the appropriate speed and parity if necessary.

3. If your equipment has a modem in a separate unit, it may have a power switch to beset to "on".

If your terminal is connected via a switched line:

4. Pick up the telephone and dial the telephone number of your System.

5. When the telephone connection is made, you will hear a continuous whistle. Thenpress the "line" key (or the equivalent for your terminal, as indicated in the operatingdocumentation).

6. For asynchronous terminals, the operator normally enters the letter "H" at thekeyboard, to determine the line speed and to complete the physical connection, (seesections "ACCESSING THE TERMINAL MANAGER").

2.2 CONNECTING A TERMINAL THROUGH THE PAD FACILITY

The procedures for calling the CNS7 System, through an X.25 network from your terminalare described below (refer to figure 2-3).

1. Set/verify the position of the speed selection on the terminal (see your terminalinstallation manual).

2. If your terminal is connected via a switched line, pick up the phone and dial up thenumber of the PAD facility.

3. After receiving the Public Data Network (PDN) banner, the operator can set newPAD parameters or profile. The commands he will need to use depend on thenetwork (refer to your PDN documentation).

Enter the new profile if this is required.

4. Enter the Call Command. This comprises a string of characters the length of whichwill depend on whether the password is used and the length of the device mailboxname.

The first 9 characters for the X.25 subscription number of the CNS7 SystemThe next character a D for the password data field to be echoed or a P for thepassword data field not to be echoed.

Note for teletel access (France only) :

1. You must press the " * " or key on the Minitel terminal in place of "P" or "D".

2. The X.25 subscription number of the CNS7 System must always be preceded by a " * ".

The next 4 characters are for the password (if it is declared in the NS object).The next 8 characters are for the device mailbox (when the -MBSEL option ispresent on the NR-PAD directive).

The password parameter is checked against the string introduced by-PSSW option of theNS-X25 directive to verify that the X.25 user has authority to enter the network. If PSSWis not specified in this directive, this parameter is not checked.

Mailboxes (MB) wich are mapped eventually to the network route (NR) of type PAD allowterminal users to select a device (DV) using the PAD access in two ways:

• by specifying which mailbox (MB) should be used (see figure 2-4),

• by NOT specifying the mailbox name (see figure 2-5).

If the mailbox is specified the device mailbox parameter (4 to 8 alphanumeric characters)
