Large countries with heavily travelled metropolitan areas, each of which might be served by a number of different airports, have a special obligation to ensure that air traffic control (ATC) centers are not only connected to their respective radar stations, but to each other as well. The same can also be said of countries comprised of multiple islands, each one of which is served by its own airport, as well as sparsely-populated countries with widely dispersed airports but only one fully-equipped ATC center.
RAD Data Communications offers a complete, hierarchical solution for connecting remote radar sites to the airports they serve, and data from those airports to others like them.
The RAD solution employs Megaplex-4100 and Megaplex-2100 or Megaplex-2104 multiservice access multiplexers. At radar sites, the Megaplex units multiplex V.35 or V.24 legacy traffic onto an E1/T1 line. E1/T1 lines from multiple radar sites terminate at the ATC center using a Megaplex-4100. Megaplex-4100 units at the ATC sites, in turn, are connected to each other over either SDH/SONET or IP based connections, allowing for voice and data to be shared between all airports in a given area over a common infrastructure. This flexible topology can be expanded as necessary to accommodate additional geographic layers.
The modular Megaplex multiplexers support dedicated data, digital and analog voice, ISDN, video, and LAN services over n x 64 kbps, single or dual E1/T1, DSL, or Ethernet uplinks. Supporting an optional Ethernet main link and incorporating pseudowire circuit emulation technology, the Megaplex also enables TDM transport (40 E1, 50 T1) over a 100 Mbps fiber ring or daisy-chain topology with under 50 ms restoration capabilities. In the event that the radar installations employ low-speed data, the Megaplex can broadcast the traffic to multiple locations.
The entire solution can be managed from a single location using the carrier class RADview-EMS element management system. In addition to featuring a plug-in for IBM Tivoli's Netcool®/OMNIbus™ fault management, RADview-EMS allows seamless communication with network-wide platforms for resource management, performance management and service provisioning, as well as with carriers' proprietary OSS.

RAD’s Megaplex-4100 multiservice access node, a high-capacity, carrier-class multiservice concentrator, supports transport over fiber or copper of multiple TDM and next-generation services on PDH/SDH/SONET or packet-switched networks (PSNs). The Megaplex-4100 provides an efficient and cost-effective tool for integrating various data interfaces, rates and user services. These include Fast Ethernet and Gigabit Ethernet as well as low speed n x 64 kbps data, high speed data (up to STM-4/OC-12), digital voice, analog voice, and ISDN. The device also features an internal cross-connect matrix of up to 7,872 DS0 channels, enabling it to cross connect traffic directly from one channel to another.
The RAD solution provides for the option of ensuring full redundancy over wireless links by deploying an Airmux-400 broadband wireless multiplexer at each radar site and ATC center. The Airmux-400 delivers both native Ethernet and TDM services over a single wireless link in various sub-6GHz frequencies.
