Configuring Systems for Terminals, Printers, and Other Serial Devices (32022-90051)

Introduction

Typical Network Conﬁgurations

Host-based management also has the capability to provide the

following types of network connections. These connections are described

later in this section.

• PAD access from terminals connected to PADs to the system that is

managing the DTC.

• X.25 Network Access from other systems connected to a PSN to the

system that is managing the DTC.

• Telnet access from terminals connected to the DTC ports to systems

running ARPA standard Telnet services.

• Multi-System Access to other HP 3000 systems on the LAN.

• Back-to-Back Access from one DTC port to another.

PC-Based Management

When an OpenView Windows Workstation is used to conﬁgure and

manage DTCs, the HP 3000 system is using PC-Based Management.

Conﬁguration and control information for the DTCs is maintained on

the OpenView Windows Workstation running the OpenView DTC

Manager software. This information is downloaded from the

workstation to each of the DTCs being managed. The OpenView

Windows Workstation must reside on the same LAN as the DTCs which

it manages.

When PC-Based Management is used, the DTCs are able to function as

datacommunication servers for multiple computers on the LAN. These

systems can be HP 3000s, HP 9000s, HP 1000s or third-party nodes,

which run the ARPA standard Telnet service.

PC-Based Management provides all of the network connections

described in the following pages.
