The synchronous optical network (SONET) asynchronous transfer mode (ATM) ring architecture called SONET/ATM ring using point-to-point virtual paths (SARPVPs) is discussed. A cost-effective three-phase network evolution path for supporting both the switched and nonswitched DS1 and DS3 services and a possible operations system (OS) evolution path under the proposed three-phase network evolution scenario are described.<>
