Numbering Plan

This part is based on the principles of the networking philosophy discussed in Part
1 and features the different types of internal and external numbering plans avail-
able in the various systems. It explains the differences between internal number-
ing plans for the private network and external numbering plans for the public net-
work. It tells you what you need to know when creating numbering plans for each
particular network.
Identification Elements
Correctly identifying and displaying a call is the essential requirement for ade-
quately implementing the system's networking philosophy. Chapter 3 looks at
how the origin of a call is identified using different ringing tone patterns and how
the caller's number (CLIP) or name (CNIP) is displayed. It describes how CLIP and
CNIP displays are created under different system conditions, how they can be
influenced, and how to suppress the CLIP display.
Routing Elements
The purpose of a routing element is to distribute incoming and outgoing calls to
their destinations. A good, adaptable routing architecture is extremely important
in connection with private networks in particular. The system resolves call routing
by using modular routing elements that ideally support any adapted, situation-
based configuration. Chapter 4 features all the elements involved in call routing.
The multitude of setting options does, however, involve a considerable amount of
configuration. That is why the initialization configuration has been selected in
such a way that many settings no longer have to be adapted when configuring a
stand-alone PBX.
Call Routing
Chapter 5 describes the interplay between the routing elements for the various
types of traffic: call routing for internal, incoming and outgoing traffic. Other top-
ics include Least Cost Routing, exchange-to-exchange traffic, transit routing in the
private leased-line network, overflow routing and break-out.
