NS Point-to-Point Network Link/XL, Technical Data
For HP 3000 Series 900 Computer Systems Product Number 36922A
The NS Point-to-Point Network Link for MPE/XL-based systems provides
the network connection for an HP 3000 Series 900 computer to
communicate with another HP 3000, MPE/XL- or MPE/V-based system.
Customers can connect HP 3000s using NS Point-to-Point with either a
leased line or switched auto-dial line. Customers with direct-connect
configurations or requirements should use the LAN links.
[Figure 1 (NS Point-to-Point Network Link/XL diagram) Caption: none]
Features
o Implements industry-standard Defense Advanced Research Projects
Agency (DARPA) TCP/IP protocols from the transport and network layers
of the OSI Reference Model.
o Provides packet routing for transport access over multiple nodes.
o Provides gateway capability for transparent access between networks.
o Includes integrated node management software for on-line
configuration and logging.
o Provides programmatic access so users can write distributed
applications between HP 3000s. The Network InterProcess Communication
(NetIPC) intrinsics provide this programmatic interface.
o Provides access to higher level services such as Virtual Terminal,
Network File Transfer, Remote Process Management, Remote Database
Access, and Remote File Access when used in conjunction with
NS3000/XL Network Services (P/N 36920A).
o Supports LAPB protocol, an OSI standard for full-duplex line
communication.
Functional Description
This product can be used in conjunction with NS3000/XL Network Services
Software (P/N 36920A), or it can be used as a standalone link with
user-written applications by using the NetIPC intrinsics. The NS3000/XL
Network Services software provides the user-level services to perform
functions such as Network File Transfer, Virtual Terminal, Network File
Access, and Remote Process Management. The programmatic access via the
set of NetIPC intrinsics allows customers to write their own
distributed applications on different nodes to exchange information in
an efficient, peer-to-peer manner.
With NS Point-to-Point 3000/XL customers' networks can be connected
in a way that is transparent to users and allows high connectivity
between networks. For example, a transparent gateway can be configured
between a point-to-point network and a LAN. Consequently, users on the
point-to-point network would be able to transparently access resources
on the LAN, and LAN users would be able to transparently access
resources on the point-to-point network.
Users do not need to know the network topology. This transparency
means that the user simply specifies the destination node name for
access to another CPU on the same network or for access to a remote CPU
on a different network.
NS Point-to-Point 3000/XL Network Link (utilizing the LAPB protocol
only) is supported to work with all full duplex auto-dial modems which
work with the DS Point-to-Point Modem Link or the NS Point-to-Point
3000/V Network Link in full duplex mode.
The following is a list of full duplex modems which have been
verified by HP to work with the NS Point-to-Point 3000/XL Network Link
utilizing the LAPB protocol:
o AT&T 201C (Dataphone 2400)
o AT&T 209A (Dataphone 9600)
o AT&T Dataphone II 2024A
o AT&T Dataphone II 2048A
o AT&T Dataphone II 2096A
o AT&T Dataphone II 2248A

Product Components
Hardware
NS Point-to-Point 3000/XL Network Link includes the hardware interface
card and 5-meter cable for connection to the user's modem. Users with
direct connect configurations or requirements should use HP LAN Links.
The hardware interface is the Programmable Serial Interface (PSI) card.
The PSI microprocessor utilizes all of the communication data link
protocol, thus relieving the HP 3000 of that task. The PSI architecture
accommodates line speeds from 1200 bps to 64 Kbps.
Software
NS Point-to-Point 3000/XL Network Link provides the OSI level 2
Standard, LAPB Protocol. LAPB provides full-duplex transmission,
thereby eliminating line turn-around time.
The network transport software, TCP/IP, implements the de facto
industry standard DARPA TCP/IP protocols. TCP/IP follows the OSI
Reference Model specifying the transport and network layers.
Product Requirements
o An HP 3000 Series 900
o A single mid-bus slot
o At least 16 Mbytes (24 or more are recommended) of memory. See your
HP System Engineer to help determine your requirements.
o Leased line or switched auto-dial line
o Full-duplex modems
Migration from DS Point-to-Point and NS Point-to-Point 3000/V
The NS Links and Services are HP's new generation of communication
products providing enhanced capabilities over that of the DS Links and
Services. Customers with DS products currently installed are encouraged
to migrate their networks to the NS product line. When planning this
migration, both services and link products need to be considered.
User applications written using DS services will run with little
modification under NS3000/XL Network Services. Customers need to be
aware that program-to-program communication (PTOP) is not supported in
the MPE/XL environment. Customers whose applications use PTOP are
strongly encouraged to move to the newer, more efficient NetIPC
environment for MPE/XL user applications. The NS Point-to-Point 3000/XL
Link can be added to networks that currently include DS link products.
In order for DS nodes to communicate with NS/XL nodes, the DS node will
have to go through an intermediate NS/V node. Customers are urged to
migrate their DS nodes to NS/V nodes to eliminate networking confusion
and to enhance performance.
The NS Point-to-Point 3000/XL Network Link product conforms to
layers 1 through 4 of the OSI seven-layer model. The DS Link product
predates the OSI model and, therefore, has a different architecture
from the NS Link product. As a consequence of these architectural
differences, DS/3000 Point-to-Point and NS Point-to-Point 3000/XL
cannot communicate with each other.
It is recommended that users establish a migration plan with an
HP Network Consultant or Datacom Specialist.
Installation and Configuration Policy
The customer is responsible for loading the NS Point-to-Point 3000/XL
Network Link software onto the system. Hewlett-Packard will install the
Programmable Serial Interface (PSI) and provide connection to the
customer's communication line (provided the line is available at
installation), and will perform minimum configuration of the NS
Point-to-Point 3000/XL 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 on-site to install the PSI and perform
minimum configuration of the NS Point-to-Point 3000/XL Network Link,
the customer is responsible for the following:
