FOREWORD

This document is being developed by the APCO Project 25 Interface Committee (APIC) Encryption Task Group (ETG) for publication as a TIA standard.

TIA Standards are designed to serve the public interest by eliminating misunderstandings between manufacturers and purchasers, facilitating conformance, interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining the proper telecommunications product for their particular need. Existence of such Standards shall not in any respect preclude any Member or non-Member of the TIA from manufacturing or selling products not conforming to such Standards.

Except as provided in the Engineering Manual, Standards are proposed or adopted by the TIA without regard to whether their proposal or adoption may in any way involve patents or intellectual property on articles, materials, or processes. By such action, the TIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting TIA Standards, to parties manufacturing or selling products or services conforming to such Standards or to users of such products or services. Other TIA rules respecting Standards where patents are involved are contained in the Manual and should be read in conjunction with these Guides-PV. Furthermore, in all cases specific requirements and restraints expressed elsewhere in these Guides must govern.
