Hybrid WDM/TDM/Data solutions enable the extension of native unicast, broadcast and multicast data transport services, based on Ethernet, IP or SAN switching, bridging and networking capabilities, over a public SONET/SDH/WDM transport infrastructure. The hybrid approach enables network operators to incorporate basic connectivity services such as Ethernet private/virtual lines, transparent LANs and Internet traffic backhaul and SAN interconnect to cater to both point-to-point and point-to-multipoint connectivity needs. Typical application scenarios that can benefit from such services include: 1. Inter POP connections 2. Corporate LAN/SAN interconnection 3. Ethernet VPNs 4. Internet Services Access Since data transport is compatible with the public SONET/SDH transport infrastructure, these value added connectivity services can be provided beyond the immediate geographical area where the equipment is installed. Data services can be provided with reliability, interoperability and manageability already found in today's public transport networks.
