SONET Networking Hub Application Underfilled fibers feed into a SONET hub which consolidates the traffic onto one fiber for transport to the switching node. At the switching node, the traffic is segregated into switched and non-switched (special service dedicated lines), DS-1 and DS-3, or any combination thereof. ATM Interconnect SONET enables network providers, including telephone companies or other service providers, to efficiently deliver wideband and broadband service to their business customers. With an ATM multiplexer or switch deployed at the provider location, DS-1, DS-3, and OC-3 bandwidths can be delivered directly to business customers’ locations. The ATM device can interface transport products offered by several vendors. Narrowband service, such as ISDN, can be delivered on various NGDLC access products using an OC-3 or OC-12 feed to the host switching node. 57 SONET <strong>101</strong>
