Planning Aid

A customer has specific requirements for a telephony and data traffic infrastruc-
ture. The task is to determine how to convert these requirements into the best
possible solution. The entire decision process is iterative. In other words, the items
listed are not to be processed simply one after the other; instead, you need to
return to previously defined parameters and, possibly, re-define them all over
again.
You need to determine the following fundamental network properties:
• The number and types of systems to be networked
• Traffic Volume
• The routing in a private network
• The type of connection between two systems
• Accesses to the public network
• Dialling through from the public network
• Incorporating virtual subscribers
• Incorporating Centrex
• Numbering requirements
• Features to be supported
6.1.1

Number and Type of Systems to be Networked

Determine the number of nodes and ascertain whether the use of a virtual PINX
(Centrex) is appropriate:
• What locations are there?
• Which locations are to be networked?
• Is a separate system required for each location?
• What is the optimum number of nodes for each location? Would it make sense
to integrate a down-circuit cordless system?
• What types of system are the best suited?
• Which systems are to be networked and how (virtual, fixed)?
• Would it make sense to integrate a Centrex solution? (A Centrex solution may
make sense if, for example, some of the subscribers are separated by long dis-
tances.)
