Configuring a X.25 Node

 

Configure an X.25 Network Interface

 

An address key called POOL is already preconfigured for you though it

NOTE

 

doesn’t show up on the screen. POOL allows the node being configured to

 

receive any incoming calls even if the remote system’s address is not

 

configured on this screen. POOL will also allow you to use NetIPC to

 

programmatically provide an X.25 address that is not configured on this

 

screen. If you want to delete the POOL address key, in the last line of the

 

X.25 Virtual Circuit Configuration screen enter a 3 (for switched VCs)

 

and press the [Go To] key. That brings you to the X.25 SVC Address Key

 

Paths screen where you can then remove the default name POOL by

 

typing over it with spaces and then saving the data.

Step 4. If the address type is a switched virtual circuit complete steps a through c, but if the address type is a permanent virtual circuit, skip to step 5.

a.In the Remote X.25 address field, enter the X.25 address of the remote host for X.25 public data networks or private networks.

b.Make sure the name of the facility set you are using is in the Facility set field. You may either choose the default facility set (STDSFSET) or enter an alternative. If you are configuring a new facility set, enter a new name. (To modify facility set parameters, enter a 5 in the last field on the screen and press the [Go To] key.)

c.In the Security class field, enter the level of logical security you want to have on this particular entry. The possible values are IN (accept calls from the address), IO (accept calls from and send calls to the address, default), OU (send calls to the address, incoming calls are rejected), and LK (block calls to or from the address).

Step 5. If the address type is a permanent virtual circuit (PVC), in the Permanent VC number field, enter the PVC number of the PVC on the remote node. This value cannot be greater than the number of PVCs for which you are subscribed. It must be within the PVC range you defined during DTC configuration.

Step 6. After you have finished entering new information for each remote node, press the [Save Data] key. (Press the key once for each remote node you are configuring.)

Step 7. If you have completed configuration of X.25, press the [Validate Netxport] key and proceed to Chapter 10 , “Validating and Cross-Validating with SYSGEN.” Otherwise, press the [Prior Screen] key to return to the X.25 Configuration screen.

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.
