Conﬁguring DTCs Step-by-Step

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 information for each DTC connected to the system.

• 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.

• 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.
