Optical services activation platform
The optical services activation platform (OSAP) 4800 leverages cost, performance, and flexibility of Ethernet to enable scalable, soft-tunable packet services over existing optical-network infrastructures. The OSAP 4800 brings packet-switching efficiency and intelligence to SONET/SDH transport networks, allowing providers to readily deploy highly resilient, high-revenue optical Ethernet services with time-to-service, global coverage, and cost of ownership. Current voice and private-line revenues are protected with OSAP's integrated TDM support, and the protocol-mediation capabilities further reduce service costs by replacing multiple WAN access technologies with a simple, service-aware, Ethernet "plug in the wall."
