Configuration Directions, Introduction

CHAPTER 1

Introduction

The DCT1900 system was developed as a modular system in order to obtain maximum flexibility in initial configuration and future growth. Each system can be configured to satisfy the specific customer requirements.

The Configuration Directions provide an explanation of the different factors that influence the size of a system and their acceptable values. Restricting limitations are also discussed. The factors that determine the final configuration of a system are:

znumber of Base Stations

znumber of Portable Telephones in the coverage area

ztraffic requirements for the system

Furthermore, the system has a number of restrictions that give limitations to the configuration. These items are explained in the following chapters.

To determine a system configuration, the limitations of the system must be known first. These are described in Chapter 2.

The number of Base Stations determine the number of CLCs to be used. The number of CLCs, together with the cable lengths, define the power requirements for the power supply and the number of SLUs and/or CLUs to be used. The required number of Base Stations can be found by doing a site survey. Site Surveys and Base Station powering are discussed in Chapters 3 and 4.

The traffic requirements for a system are determined by the amount of Portable Telephones in the coverage area (visiting Portable Telephones included), the estimated traffic generated per Portable Telephone and the GOS accepted by the customer. These figures define the number of SPUs required. Traffic requirements are explained in Chapter 5.

When the number of each system board type needed in a system is known, the number of cabinets, power supplies, internal cables, etc. can be calculated. The relationships between all these parts are outlined in Chapter 6.
