ISDN Field Trial Guidelines Handbook

image of 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.



Network requirements

This section describes the network aspects of the ISDN technology required to assist an administration or RPOA in the implementation of ISDN field trials. The information is provided in a manner which links the technical network capabilities, as described in the ISDN architecture, to functionality, service features, and implementation issues as would be expected in an ISDN field trial. This is achieved by introducing a generic ISDN field trial network model, exposing and detailing those network requirements considered to be most pertinent to a field trial, and linking these to relevant CCITT I-series and other Recommendations in alignment with other sections of this handbook.
