Description

This Standard covers mechanical and electrical requirements of
service wires containing at least one coaxial core and optionally
up to six twisted pairs, used for service applications to extend
the telephone/multimedia circuit from the distribution terminal to
the subscriber's station protected NID (Network Interface
Device) or protected NIU (Network Interface Unit).

Furthermore, a distinction between Type I and
Type II is made with regard to transmission
characteristics and shielding materials of the coaxial unit.

Buried Service Wire is used to extend buried telephone plant
from the distribution cable to the subscriber.

The coaxial unit is intended to be used for either RF or
compressed digital video and radio transmissions. This unit shall
also allow bi-directional traffic.The coaxial unit should also be
capable of carrying high speed digital signals for LAN/WAN
applications (such as T1, ISDN, etc.) as well as POTS (Plain Old
Telephone Services). The network supporting these protocols will be
based upon physical lines having a characteristic impedance of 75
Ohms. The coaxial units are specified in three and four common
sizes for Type I and Type II
respectively, to accommodate different drop lengths.

The twisted pair wires are intended for voice and data
transmission and their characteristics are based upon existing
system requirements and projected application needs.

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 buried outside plant use. The parameters covered provide
material, construction, and performance requirements.

Because this Standard does not cover all details of individual
wire designs, it cannot be used as a single document for
procurement of product. This Standard is intended to be used in
conjunction with an individual product specification that provides
complete design details for the specific 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.
