Scope
This standard provides uniform functions and requirements for performance monitoring (PM) and alarm/status monitoring for digital transmission signals at the DS3 rate. It is intended to be used in conjunction with the core document -- T1.231-2003. 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 DS3 digital transmission rate. 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 DS3 rate. ? It describes the functions related to the collection@ storage@ thresholding@ and reporting of PM information; ? 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.
