scope:

This standard provides uniform functions and requirements for performance monitoring (PM) and alarm/status monitoring for digital transmission signals in the SONET hierarchy. It is intended to be used in conjunction with the core document ATIS-0300231.2013

Purpose

This standard is written to provide the minimal set of requirements to provide for uniform and consistent PM and alarm/status monitoring for the SONET digital transmission rates. This standard provides definitions for performance primitives (anomalies and defects), performance parameters, and performance failures.

Application

The application of this standard is as follows:

 It provides definitions of performance and alarm/status parameters, both required and optional, applicable to network elements providing non-intrusive transmission monitoring at the SONET digital rates;

 It describes the functions related to the collection, storage, thresholding, and reporting of PM information; and

 It establishes the PM functions that may be used at network interfaces between telecommunication carriers, at network boundaries, and at customer premises to permit compatible maintenance operations.

Although this standard establishes ranges over which transmission performance can be measured, it does not establish any requirements or guidelines for levels of performance. This standard refers to other American National Standards that address digital transmission and performance criteria.
