Introduction

Typical Network Conﬁgurations

Host-Based Management

When an HP 3000 computer is used to conﬁgure and manage DTCs, the

system is using Host-Based Management. Conﬁguration and control

information is maintained on the host, and downloaded from the host to

each of the DTCs controlled by it.

In the simplest conﬁguration, devices connected through a DTC

function as though a single cable were connecting the device and the

computer that is managing the DTC. With this conﬁguration the DTC

would communicate only with the host from which it is downloaded.

A sample network conﬁguration in which host-based management is

used in its simplest conﬁguration, is shown in Figure 1-1. System A

manages DTC 1 and DTC 2, while System B manages DTC 3.

Terminals connected to DTC 1 and DTC 2 are able to communicate only

with System A, as if a single connection existed between them.

Likewise, terminals connected to DTC 3 are only able to establish

connections with System B.
