PAD Access to MPE/iX Systems
The DTC is connected to the LAN as usual, with the MPE/iX systems to
which it has access also connected to the LAN.
Figure 7-1 depicts PAD access to HP 3000 Series 900 Systems via a
DTC equipped with the DTC/X.25 Network Access card.

Network Configuration Requirements
The parameters for asynchronous devices that can use the PAD support
facility provided by the DTC are configured through either the
OpenView DTC Manager or through host-based configuration. PAD
support information for each MPE/iX host system must be supplied via
NMMGR configuration.
PAD Configuration Values. Most of the characteristics that define
how asynchronous devices connected through a packet switched
network will act are determined by the configuration of the PAD itself.
See the documentation for the PAD for more information on how to
define the characteristics of its devices.
PAD support for the network is configured, in part, through the
OpenView DTC Manager or through host-based configuration.
Configuration values are entered to define the types of devices that may
access the network. Levels 1 through 3 of X.25 must also be configured.
