Ultra Electronics-DNE Technologies announces a new modular multiplexing protocol converter for use in tactical networks. The product, called the CV-MCU2, can be software-configured to perform CDI/NRZ/Fiber conversions or up to 4:1 multiplexing in a single 1RU chassis. The CV-MCU2 allows the tactical user to configure a single unit as either a multiplexer or a modem, or any combination of the two, allowing the circuits to operate independently or be combined as needed without replacing hardware modules when a reallocation of circuits is required.

A new universal copper/fiber/NRZ module used in the CV-MCU2 provides both an increase in port density and circuit flexibility to the tactical user, supporting up to five 20Mbps protocol conversions per 1-RU chassis. In addition, these modules now provide interoperability with deployed Perkins 2270 Fiber Optic Modems, allowing the CV-MCU2 to be a viable space-saving alternative when installing new modems in tactical communications vans.

The CV-MCU2 also uses these same universal fiber modules to multiplex up to four digital trunk groups onto a single 16Mbps aggregate, allowing field traffic at a communications van or shelter to be consolidated for more efficient throughput to high-speed radios. This consolidation results in a significant size and weight reduction over existing trunk group multiplexers, and supports both copper and fiber circuits.

The CV-MCU2 combines the features of both Conditioned Di-Phase Modems (CDIMs) and Fiber Optic Modems (FOMs), and offers a conversion to and from Non-Return to Zero (NRZ) protocols. The new universal fiber interface provides connectivity to single- and multi-mode fiber, and JTC3A 9109C devices, such as the ITT GSC-54, and Northrop Grumman MD-1272.

The CV-MCU2 uses industrial components to increase the environmental operating range to better adapt to today’s diverse deployment conditions. In addition, the CV-MCU2 chassis will also support previously deployed VersaMux 4000 NRZ Mux and CDI Mux option modules for an efficient re-use of deployed components. All cards are hot-swappable, and can be configured via a front-panel LCD interface, or through Serial DB-9 or Telnet RJ-45 ports. Additional option modules are planned to support further DoD NetCentric transition. Ultra-DNE also offers a selection of accessory cables to interface with many existing encryption devices.
