Chapter 15. Additional Planning Considerations 
This chapter provides guidance for additional planning steps that may be necessary. 
Create or Modify Communications Networks 
If you intend to use the system in a network environment, appoint a central site or system administrator to 
help design and maintain a system that provides maximum availability of all devices in the network. The 
system administrator may need to consider the following: 
v   Types of networks with which your network users must communicate (for example, local and wide area 
networks, asynchronous, coaxial). 
v   Types of communications functions that your network users need (for example, file transfer, mail, 
3278/79 emulation, X-Window server support, data conversion, printing). 
v   Communications software that is required to communicate between systems within your own network 
and with systems on external networks. 
v   International language considerations, if any, between communicating systems. 
v   Network management functions that you want to use within your network, including error-isolation 
procedures and performance and monitoring tools. 
v   Information needed to properly configure your system. The following list provides some of the types of 
information needed: 
–    Transmission speed (in bits per second) 
–    Parity checking (whether none, odd, or even) 
–    Pacing protocols required or allowed by remote system 
–    Dialing or calling protocols, such as autoanswer and autocall, and information such as phone 
numbers (including back-up phone numbers in case no connection is possible) 
–    Times you can call and communicate with the remote systems 
–    Naming and addressing requirements within your network and between your systems and remote 
systems 
–    Security relationships within your network and between your systems and remote systems 
–    Gateway or bridge requirements 
–    Information needed to configure the system software for correct operation in the network.
v   Any necessary cables, control units, or other specialized communications hardware. 
v   Preparation of communications lines: 
–    Number of concurrent communications users 
–    Amount of data to be transmitted 
–    Communications software licensing restrictions.
