Configuring a X.25 Node

Configure an X.25 Network Interface

Facility set

The facility set name is a name for a set of X.25 connection parameters. The parameters are determined by the type of X.25 network that you are subscribed to. You can configure options in a facility set so that specified options are available for every virtual circuit or negotiated for each virtual circuit on a per-call basis. This facility set will be used when a connection is made from your node to the specified remote node or from the specified remote node to your node. A Facility Set is required for SVCs if you have specified an X.25 Address Key. The facility set name must be eight characters or less, and the first character must be alphabetic. You can configure up to 128 facility sets.

To modify facility set parameters, enter a 5 in the field at the bottom of the screen and press the [Go To] key. This will take you to the X.25 User Facility Sets screen. From this screen you can create new or modify existing user facility sets. See the NS 3000/iX Screens Reference Manual for more information.

Security class

The security class is the level of logical security you want to have when a connection is made to or from the specified remote node. A Security level is required for SVCs if you have specified an X.25 Address Key. The possible values are as follows:

•IO — Both incoming and outgoing calls are accepted. This is the default value.

•IN — Only incoming calls are accepted from this particular remote address. Outgoing calls will be rejected.

•OU — Only outgoing calls are accepted to this particular remote address. Incoming calls will be rejected.

•LK — Entry is locked. No call is accepted, either inbound or outbound.

For PVCs

Permanent VC number

The PVC Number identifies a permanent virtual circuit (PVC) on the remote node. If you have entered a name in the X.25 Address Key field and are configuring PVCs, then you also have to enter a value for the PVC Number.

E3000 MPE/IX, E3000/IX specifications

The HP E3000 series, particularly the E3000/IX and E3000 MPE/IX, represents a significant milestone in the evolution of business computing, developed by Hewlett-Packard (HP) during the late 1970s and early 1980s. These systems were designed to provide robust, reliable, and efficient operation for mid-sized businesses, leveraging the power of the MPE (Multi-Programming Executive) operating system.

One of the main features of the HP E3000 series is its multitasking capability. MPE/IX allows for multiple applications to run concurrently, maximizing the utilization of system resources. This is particularly beneficial for organizations that require simultaneous access to various business applications, ensuring enhanced productivity and efficiency.

The HP E3000/IX architecture is built on a powerful 16-bit or 32-bit microprocessor, enabling it to handle substantial workloads. The system architecture is known for its modular design, which allows for easy upgrades and customization. This flexibility is essential for businesses that need to adapt to changing demands without overhauling their entire computing infrastructure.

Another notable technology incorporated into the HP E3000 series is its support for a range of storage solutions. The E3000 systems were compatible with various disk drives, providing organizations with options for data storage that matched their performance and capacity requirements. Additionally, they featured advanced data management capabilities, such as built-in backup and recovery systems, ensuring that critical business information remained secure and accessible.

Beyond hardware capabilities, HP E3000/IX and MPE/IX systems provide extensive programming support. They included tools for developing custom applications, with support for languages such as COBOL, BASIC, and FORTRAN. This versatility made it easier for businesses to tailor their software solutions to their specific needs, enhancing operational effectiveness.

Networking capabilities were also a significant innovation of the E3000 series. The systems offered robust support for various networking protocols, allowing for seamless integration with other computing environments. This facilitated communication and collaboration within an organization, as well as with external partners and clients.

In summary, the HP E3000/IX and E3000 MPE/IX systems were pivotal in delivering reliable computing power to mid-sized enterprises. With their multitasking operating system, modular architecture, advanced data management, and programming support, these systems provided an adaptable and comprehensive solution for evolving business needs. The legacy of the E3000 series is evident in how it paved the way for modern enterprise computing, focusing on flexibility, scalability, and efficiency.
