Configuring DTCs Step-by-Step

Chapter 3

3 Configuring DTCs Step-by-Step

This chapter provides step-by-step instructions for configuring Datacommunications and

Terminal Controllers (DTCs) for systems using host-based network management. If you

are using this manual to configure DTCs, it is assumed that X.25 network connections

will be part of the host-based configuration.

Before using NMMGR to configure DTCs, you should complete the worksheets provided.

See Chapter 2, “Preparing to Configure DTCs,” for more information on planning your

configuration and filling out the configuration worksheets.

This chapter includes step-by-step instructions to help you perform the following tasks:

• Configure host information

• Configure PAD Access Lists

• Configure information for each direct connect and modem card contained in any DTC

connected to the system.

• Configure information for each DTC/X.25 Network Access card contained in any

DTC connected to the system, including:

— X.25 level 1, 2, and 3 parameters

— System-to-system local user group information

— Nailed PAD connections and PAD security

— PAD switching information

— PAD incoming security information

— System-to-system switching information

• Validate your network configuration (SYSGEN cross-validation is done

automatically within NMMGR).

NOTE If you are configuring a system that does not require X.25 system-to-system or PAD

configuration, use Configuring Systems for Terminals, Printers, and Other Serial Devices

instead of this manual.
