Existing SONET/PDH/SDH infrastructure will not be replaced anytime soon.  Instead, Service Providers are focusing on using this technology more efficiently—in ways that let them offer more profitable next generation services. ANDA Networks’ EtherTone™ supports X.86 and GFP to map Ethernet directly into SONET/PDH/SDH payloads far more efficiently.

Today’s SONET/PDH/SDH infrastructure requires connections for data-based services to be provisioned on a dedicated TDM time slot on an end-to-end path. This environment has resulted in SONET/PDH/SDH networks being overbuilt to accommodate irregular bursts of traffic.

X.86 and/or GFP, however, allow the Service Provider to statistically multiplex the subscribers’ Ethernet traffic in the SONET/PDH/SDH payload.  Mapping Ethernet frames into a single SONET/PDH/SDH virtual connection results in higher bandwidth utilization, the ability to serve more customers with the existing fiber plant, and faster service delivery.  All of these benefits translate directly into CAPEX and OPEX savings.

By utilizing EtherEdge 4000 products with the complementary EtherReach 2000 series of products, carriers can effectively optimize their use of existing SONET/PDH/SDH infrastructure via Ethernet over circuit bonded technology using the industry standard GFP.
