The Megaplex-4’s ability to handle a broad range of Ethernet, data and voice services, as well as a large variety of network technologies, in a single compact managed node, makes it an ideal solution for carriers and service providers. The device also provides a perfect fit for large enterprises, utilities and transportation companies who require an efficient way to transport and provision multiple legacy and next-generation services over their high capacity pipes. Megaplex-4 can be used as a central aggregation unit for TDM and Ethernet CPEs that are connected over various access link technologies, e.g., HSDSL and SDH/SONET.

The Megaplex-4 is available with a cable management solution to reduce storage space and handling, and eliminate cable waste.

RADview Performance Monitoring

The RADview features a network element manager, end-to-end service manager for Carrier Ethernet services, performance monitoring portal for ongoing monitoring of Ethernet and IP services, D-NFV orchestrator for virtual machines and application services at the customer edge, and a network planner for resource optimization and capacity planning.

Featuring client/server architecture with multi-user support, RADview provides intuitive graphic representation of network clouds, links, nodes, end-to-end services, and network status indication. Fully ITU-T FCAPS compliant, it offers security management supporting user access profiles and allowing network partitioning.


The Megaplex-1 is specifically designed to address the needs of critical infrastructure network operators who are migrating to next-generation Ethernet or IP/MPLS communications. This includes utilities, transportation and government users. It enables seamless service migration with a scalable TDM over packet pseudowire engine and comprehensive multiservice support for PDH, high and low speed data, analog voice, and Teleprotection devices.
