     NS X25 3000/V Network Link Technical Data
     Product Number 24405A
     The NS X.25 3000/V Network Link for HP 3000 systems pro- vides a
     connection to a public or private X.25 Packet- Switched Network (PSN).
        Used in conjunction with the NS 3000/V Network Services (HP 32344A),
     the NS X.25/V link supports communications between HP systems. By
     itself, the

     [Figure 1 (NS X25 3000/V Network Link)  Caption: none]

     NS X.25/V link supports communications between an HP 3000 host system
     and remote terminals and printers connected to a Packet
     Assembler/Disassembler (PAD).
        In addition, the NS X.25/V link provides programmatic access to
     packet level 3. This allows users to develop their own protocols and
     services for communications with remote HP or non-HP systems over an
     X.25 network.

     Features
     o Fully supports the NS 3000/V Network Services (32344A).
     o Follows an OSI layered architecture.
     o Implements industry-standard DARPA TCP/IP protocols.
     o Implements the 1980 CCITT recommendations for X.25/X.3/X.28/X.29.
     o Complies with the U.S. DDN TCP/IP-X.25 standards.
     o Provides programmatic user access to the X.25 packet level for
       multivendor or customer-designed communications.
     o Provides packet routing and gateway capabilities for transparent
       access over multiple nodes and between networks.
     o Provides X.25 user facilities such as flow control, throughput class
       negotiation, closed user groups, and one- way/two-way virtual
       circuits.
     o Implements DTE/DCE modes for connection over public and private X.25
       networks, leased and direct hardwired lines.
     o Dial-up terminal access over PSNs via a network PAD to a host HP 3000
       computer system. Supports both character mode and HP VPLUS
       applications.
     o Remote terminal cluster access via an HP 2334A/5A PAD using a single
       leased line over a PSN to a host HP 3000 computer system. Supports
       both character mode and VPLUS applications.
     o Supports HP printers on an HP 2334A/5A PAD.
     o Supports both system-to-system and system-to-terminal
       communications over a single X.25 link on the HP 3000.

     Functional Description
     An HP 3000 computer with the NS X.25/V link installed is capable of both
     originating calls to and receiving calls from other computers over an
     X.25 network. It can be configured as either Data Terminal Equipment
     (DTE) or Data Circuit-terminating Equipment (DCE) to run over a public
     or private X.25 network at speeds up to 56 Kbps.
        Additional features of the NS X.25/V link include the ability to
     multiplex multiple sessions between two HP 3000 computers over one
     virtual circuit, as well as disconnecting virtual circuits after an
     inactivity time-out.

     NS 3000/V System Communications
     NS 3000/V Network Services (HP 32344A) used in conjunction with the
     NS X.25/V link enables HP 3000 computers to communicate to remote
     HP 3000 computers over public or private X.25 PSNs and direct connect
     lines. Users have access to services such as Network File Transfer,
     Virtual Terminal Access, Remote Database Access, and Remote File Access.
        The NS X.25 3000/V link implements the Defense Advanced Research
     Projects Agency (DARPA) standard Transmission Control Protocol (TCP) at
     the transport level 4. This layer is also used by the other NS network
     links, making the network topology transparent to end-users and
     applications.
        Moreover, HP 3000 computers that are configured with connections to
     an X.25 network and to an 802.3 local area or point-to-point network are
     capable of transparently routing data between HP 3000 computers on any
     of these networks. This is accomplished by the implementation of DARPA
     Internet Protocol (IP) network level 3 on all NS 3000/V network links.

     System-to-Dial-Up Terminal
     The X.25 communications software allows asynchronous terminals to
     communicate with HP 3000 computers via the X.3/X.28/X.29 conventions.
     X.25 allows users at remote sites to access and communicate with any
     HP 3000 connected to an X.25 PSN through the NS X.25/V link. The remote
     terminal connects to the X.25 network through a PAD, usually by a local
     phone call, and then attaches to any HP 3000 computer system connected
     to the network through the NS X.25/V link. Both character mode and
     applications using HP VPLUS block mode are supported over the
     system-to-PAD terminal connection. For a current list of supported
     HP software subsystems, consult your local Hewlett-Packard Sales
     Representative.

     System-to-Remote Terminal/Printer Cluster
     For applications where there are a number of terminals at a single
     remote location, the HP 2334A/5A allows up to 16 asynchronous RS-232
     point-to-point devices to communicate over a single X.25 leased line,
     with an HP 3000 computer system connected to a PSN through an NS X.25/V
     link. Both character mode and HP VPLUS block mode are supported on
     HP terminals at a maximum baud rate of 9600.
        Printers are supported as either spooled or non-spooled. Please see
     the HP 2334A/5A- X.25 Multiplexer data sheet for additional information.

     Programmatic Access
     The link also provides programmatic access to X.25 packet level 3 to
     establish communications with remote HP or non-HP applications. The
     programmatic interface, Network InterProcess Communications (NetIPC),
     provides this capability independently of the remote computers'
     protocols. It consists of routines that are accessible from FORTRAN,
     Pascal, COBOL, and SPL programs, and can manage data transfers (send and
     receive), connection states (setup and disconnection), and error
     conditions.

     X.25 Packet Level Capabilities
     The X.25 packet level 3 applications can handle parameters and elements
     such as:  Permanent Virtual Circuits (PVC), two-way and one-way
     (incoming and outgoing), Switched Virtual Circuits (SVC) Data, interrupt

12





     and reset packets, D-bit and Q-bit Call User Data (CUD), cause and
     diagnostics fields, Calling DTE address Deferred calls, X.25 user
     facility sets.
        Local User Group (LUG) is available as a system-configurable address
     table to secure access to and from remote DTEs.

     X.25 User Facilities (1980)
     The CCITT X.25 (1980 update) recommendation includes a variety of
     facilities that provide the user with a high degree of flexibility in
     operating the link.
        Flow control, which is defined by parameters such as packet size,
     window size, and throughput class can be modified on a virtual circuit
     basis for a given destination address. Closed User Groups (CUG) restrict
     the access to or from an X.25 public network to a list of X.25
     addresses. These are user-defined and managed by the network
     administration. This facility is complemented by the LUG host-based
     security mechanism. Virtual circuits can be configured to accept one-way
     or two-way traffic, thus enabling the HP 3000 computer to initiate or
     accept calls, or a combination of both.

     Other X.25 user facilities are listed below:

     The NS X.25/V link includes the hardware interface card and cable for
     connection to the user's modem. (Users with direct hard-wired
     configurations must order external interconnect cables separately.) The
     interface is the Intelligent Network Processor (INP), a 16-bit
     microprocessor board that performs all of the communication data link
     protocol, thus relieving the HP 3000 of that task.
        The maximum speed at which the HP 3000 communicates with the PSN
     depends upon the speeds supported by the PSN and the physical link
     between the HP 3000 and the PSN. The NS X.25/V link supports data
     transmission speeds from 1200 bps to 19.2 Kbps for RS-232 connections or
     from 19.2 Kbps to 56 Kbps for V.35 connections.

     Software
     The transport level utilizes DARPA standard Transmission Control
     Protocol (TCP). TCP provides end-to-end transport and multiplexing on
     virtual circuits.  DARPA Internet Protocol (IP) provides the
     internetting capability between networks. At the packet level, CCITTÆs
     1980 Recommendation for X.25 provides virtual circuit connection and
     control, packet formatting, and packet exchange.  The Network
     InterProcess Communications (NetIPC) interface is used for intrinsic
     access to the X.25 packet level.
        The LAP-B link level software provides a full-duplex communication
     connection between the DTE computer and the network DCE device.
        Additional software is included for nodal management, configuration,
     logging, and diagnostics.

     Product Requirements
     o An HP 3000 MICRO 3000, MICRO 3000XE, LX, GX, Series 37, 39 through 70
     o Uses a single INP slot
     o MPE V/E Extended microcode firmware
     o At least 2 Mbytes of memory (Generally, systems that are now memory
       limited should add 1 Mbyte to maintain current system performance.)

     Migration from the DS/X.25/3000 Link
     The NS Links and Services are HP's new generation of communication
     products, providing enhanced capabilities over that of the DS Links and
     Services. User applications written using the DS Network Services
     require little modification to run over the NS 3000/V Network Services.
        The NS X.25/V link conforms to layers 1 through 4 of the OSI
     seven-layer model. DS X.25 predates the OSI model and therefore has a
     different architecture than NS X.25/V. As a consequence of these
     architectural differences, DS X.25 and NS X.25/V links cannot
     communicate directly with each other. However, both the DS X.25 and the
     NS X.25 link software can coexist on the same node and share an INP for
     connection to the X.25 network. As a result, NS X.25 network migration
     can be phased in while maintaining full network connectivity. A
     migration planning guide can be ordered with the NS X.25/V link for use
     in planning each customer's move to an NS-based network.
        Customers using Telenet Public PAD access should contact their
     HP Systems Engineer for information on migration considerations.
        Additional assistance is available with the purchase of the
     HP Network Support products.

     Installation and Configuration Policy

15





     The customer is responsible for loading the NS X.25 3000/V Network Link
     software onto the system. Hewlett-Packard will install the Intelligent
     Network Processor (INP) and provide connection to the customer's
     communication line (provided the line is available at installation), and
     will also perform minimum configuration of NS X.25 3000/V Network Link
     in order to verify minimum product functionality. These activities are
     included in the product purchase price.

     Customer Responsibility
     Prior to having HP personnel onsite to install the INP and perform
     minimum configuration of the NS X.25 3000/V Network Link, the customer
     is responsible for the following:
     o Providing HP with the information necessary to complete the Network
       Implementation and Support Plan (NISP) including:
       - System Configurations
       - Logical network map identifying relevant traffic flow
       - Physical network map identifying relevant network hardware
         components
     o Installing and verifying the communication line between the HP 3000
       system and the X.25 network. When necessary, subscribing to the
       appropriate administration for access to the public PSN.
     o Obtaining a valid IP address prior to configuration of the NS X.25
       3000/V Network Link.
     o Updating the HP 3000 system to the proper release level and installing
       the NS X.25 3000/V Network Link software using AUTOINST. Refer to the
       HP 3000 Update Manual (P/N 32033-90036).
     o Verifying that all of the necessary software modules have been
       successfully installed by AUTOINST and are at the correct version
       levels using the NMMAINT.PUB.SYS utility.
     o Performing full system backups (as necessary) and ensuring that the
       HP 3000 system and personnel with HP 3000 system management knowledge
       and networking knowledge are available when HP is onsite to complete
       the installation and minimum configuration of the NS X.25 3000/V
       Network Link.

     The customer is also responsible for completing the configuration in
     order to fully integrate the NS X.25 3000/V Network Link into the
     existing customer network after HP has completed the minimum
     configuration of the NS X.25 3000/V Network Link.

     HP Responsibility
     Following the installation of the software component of the NS X.25
     3000/V Network Link, HP is responsible for the following:
     o Installing, verifying, and connecting the Intelligent Network
       Processor (INP) card for the NS X.25 3000/V Network Link to the
       customer's communication line.
     o Confirming that all of the necessary software modules have been
       installed and are at the correct version level.
     o Configuring the NS X.25 3000/V Network Link to a minimum default
       configuration necessary to verify the software and hardware
       functionality on the local node. This includes configuring the INP for
       use by the NS X.25 3000/V Network Link into the system I/O
       configuration via SYSDUMP, and configuring the link and Network

16





       Interface (NI) in the network configuration file (NSCONF) using the
       NMMGR utility.
     o Verifying the NS X.25 3000/V Network Link configuration by issuing the
       NETCONTROL start command for the NS X.25 3000/V Network Link NI, and
       performing an NS X.25 3000/V offline network loopback between the
       HP 3000 and the X.25 network.

     These steps complete HP's portion of the installation and minimum
     configuration of the NS X.25 3000/V Network Link.

     Additional Implementation Assistance
     For implementation needs that go beyond installation, the customer can
     either provide self-support, or can purchase additional services from
     HP. These services include Network Startup and HP ConsultLine. In
     addition, the customer can also purchase service from HP on a
     time-and-materials basis.

     Network Startup includes implementation scheduling and coordination
     assistance, network configuration and verification testing, and network
     documentation.
