Introduction

Typical Network Conﬁgurations

X.25 Network Access

X.25 iX System Access, when used in conjunction with DTC/X.25

Network Access, allows you to establish a DTC/X.25 iX Network Access

Link, thus connecting an HP 3000 computer to a public or private X.25

PSN. The X.25 network protocol processing is done by the DTC/X.25

Network Access card installed in the DTC. If PC-based management is

used, then multiple HP 3000s can share the same X.25 network

connection. If Host-based management is used, then X.25 access is

limited to the HP 3000 that is managing the DTC.

Figure 1-3 shows a Wide Area Network (WAN) consisting of two DTCs

joined by an X.25 PSN. Both DTCs must include at least one DTC

equipped with at least one DTC/X.25 Network Access card. The DTCs

can be managed by either OpenView Windows Workstations or by the

host system.
