46、S SECTION 1 GENERAL1.1 PURPOSE: The purpose of this Standard is to establish generic technical requirements that may be referenced by individual telecommunications wire specifications covering products intended for normal outside plant use. The parameters covered provide material, construction, and
47、performance requirements. Because this Standard does not cover all details of individual wire design, it cannot be used as a single document for procurement of product. It is intended to be used in conjunction with an individual product specification that provides complete design details for the spe
48、cific wire type and designates the applicable performance requirements. Such individual wire specifications may be prepared either by the user or the manufacturer. The specification designated for procurement is at the option of the user. The manufacturer and user of these wires should consider the
49、selection and availability of appropriate hardware in the installation of these products. 1.2 SCOPE: This Standard covers material, mechanical and electrical requirements for Aerial Service Wire (ASW) intended for use principally in extending a telephone circuit from a distribution cable terminal to a subscribers station protector or network interface device (NID). 1.3 OPTIONS AND INFORMATION: This Standard is arranged in sections covering specific areas of wire requirements and may be referenced as complete sections or a
