Start Links and Services

Start Software Loopback

Issue the following command (NM capability required) to start software loopback:

NETCONTROL START;NET=loopbackNIname

This starts up the control process, the transport, and software loopback. Note: when you use guided NMMGR to create any NI, a loopback network interface (whose loopbackNIname is LOOP) is automatically generated. The loopback NI must be started if you wish to perform local loopbacks or to DSLINE to the local node, also some ARPA services need loopback to be started.

Start a Link

Issue the following command (NM capability required) to start a link:

NETCONTROL START;NET=NIname

This starts the link identified by the NI name. (If no previous NETCONTROL START command was issued, then the control process and transport are also started.) The NIname is the network interface (NI) name that you supplied during NS configuration. You can start the link before loopback if you want. Start other links as needed.

Start a Host-Based X.25 Link

If your network includes X.25 links and you are using host-based network management, you will need to use the DTCCNTRL command before you issue the NETCONTROL START command. DTCCNTRL starts X.25 and PAD support for the DTC/X.25 Network Access card. Issue the following command (System Operator capability required):

DTCCNTRL DTC=dtcname;CARD=cardnumber;FUNC=function

where function is one of the following:

STARTX25 to start X.25 services;

STARTPADSUP to start PAD support services;

STARTBOTH to start both X.25 and PAD support services.

For more information on starting host-based X.25 links as well as other uses of the DTCCNTRL command, see Configuring and Managing Host-Based X.25 Links.

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.
