42 Target Audience and Structure of the System Manual
System Functions
This chapter is based on the principles of the networking philosophy discussed in
Part 1 and features the different types of internal and external numbering plans
for private and public networks.
Other system functions:
• Subscriber identification and display using CLIP (Calling Line Identification Pres-
entation) and CNIP (Calling Name Identification Presentation)
• Routing elements and the way they interact in distributing incoming and out-
going calls to network and user-network interfaces
• Routing data services to destination tables or individual destinations
• Logging and output of call data and call charge data
Numerous examples are used to illustrate this complex subject and to make it eas-
ier to understand.
Features
Each subscriber has the possibility of activating a multitude of features in day to
day telephony operations. Depending on the terminal type connected, this is done
using function keys and menu-driven key sequences. Most of these features can
be activated using */# procedures even on terminals with the lowest level of fea-
tures. The table in "Features Overview", page 563 provides an overview of the
features available with the different terminal types.
"Part 3 Planning"
Part 3 begins with a system overview of the basic systems and their expansion
stages using expansion cards and modules. It also looks at technical and licence-
related system and expansion limits. The customer's requirements are the prime
concern when expanding a system. The objectives, demands and requirements of
the customer must be reconciled with the technical circumstances and possibili-
ties. Part 3 supports you in accomplishing the following tasks:
• Determining customer needs
• Coordinating objectives, requirements, wishes and possibilities
• Drawing up a rough concept
•Planning the system
