ISDN Field Trial Guidelines Handbook
This document on ISDN field trial guidelines has been prepared specifically to provide help and guidance to those countries wishing to initiate ISDN field trials. The document calls on the experience already gained through existing ISDN installations to provide the necessary background and information. Additionally many countries have already progressed towards integrated digital switching and transmission for voice networks, (commonly referred to as IDN) as a necessary precursor to the introduction of ISDN. The primary purpose of the field trial guidelines handbook is to support development of planning and implementation requirements necessary for the conduct of a successful ISDN trial, including evaluation of the results.

Planning
Planning of the ISDN field trial is an essential step to ensure proper implementation, evaluation and future evolution of the trial, also to ensure that the trial will not have a negative impact on the existing network plans. The success of the trial depends to a large extent on the quality of planning carried out. This chapter provides guidelines on the planning process involved to establish an ISDN field trial, and its associated technical parameters. Having considered these planning parameters, it is recommended that a planning document is prepared to include the directions and strategies that will be adopted by the organization in implementing the trial. This document should be updated as necessary as the trial progresses to include subsequent changes. Based on the information of technical planning, the detailed operation of the project should be planned by the project management team.
