ATM Virtual Path Ring Functionality in SONET - Generic Criteria


Document Number GR-2837
Issue Number 04
Issue Date Feb 1998
    ORDERING INFORMATION

    ABSTRACT: This document provides the view of Telcordia on proposed generic criteria for incorporating ATM Virtual Path functionality into SONET
    rings. SONET ATM VP rings are ring configurations with a SONET physical layer that may either carry ATM traffic exclusively or a
    combination of ATM and STM traffic. The former are supported by pure ATM ADMs and the latter by Hybrid ADMs.

    This GR introduces a modified terminology for SONET, ATM, and hybrid SONET/ATM entities and provides a general SONET ATM ring
    evolution overview. It further introduces functional models, discusses potential applications and operations functionality, and
    presents a set of ATM Virtual Path level requirements for SONET ATM VP ADMs. Early broadband ATM services may utilize existing SONET
    infrastructures in a Hybrid SONET/ATM network approach. In such situations, the Hybrid ADM provides a cost-effective evolution path to
    ATM networks. In other situations without an existing SONET infrastructure, pure ATM ADMs may serve in ring applications where only
    ATM traffic needs to be supported.

    This GR also includes one or more Issue List Reports (ILRs) that details open or closed technical issues in the main document. The
    ILR(s) are automatically sent free of charge to the GR document purchaser.

    Components of this product are:
    GR-2837-CORE
    GR-2837-ILR
