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 e3000

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 e3000s can share the same X.25 network connection.

If PC-based management is used, or if Release 7.0 or 7.5 is installed with the latest DTS

patches, then multiple HP e3000s can share the same X.25 network connection. If

Host-Based management is used, and the latest DTS version is not installed, then X.25

access is limited to the HP e3000 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.
