scope:

This standard establishes common criteria for Synchronous Optical NETwork (SONET) interfaces at standard rates associated with the Network Interface (NI). Covered herein are maintenance and operation functionality at the SONET Section, Line, and Path layers specifications. Other necessary criteria for compliance with the proper interfacing of the connecting customer installation equipment are found in the other document of this series. Compliance with this standard addresses network and customer installation compatibility and is not to be construed as a constraint on the internal operations of the network or the customer installation equipment. Other documents included in the ANSI T1.416 series (at the time that this document was approved) are listed below.

ANSI T1.416.01-1999, Telecommunications - Network to Customer Installation Interfaces - Synchronous Optical NETwork (SONET) Physical Media Dependent Specification: Multi-Mode Fiber

ANSI T1.416.02-1999, Telecommunications - Network to Customer Installation Interfaces - Synchronous Optical NETwork (SONET) Physical Media Dependent Specification: Single-Mode Fiber

ANSI T1.416.03-1999, Telecommunications - Network to Customer Installation Interfaces - Synchronous Optical NETwork (SONET) Physical Media Dependent Specification: Electrical

The provisions of this standard are intended to be consistent with applicable requirements concerning safety and environmental conditions.
