Mercury ES

Mercury Communicator Unit (MCU)

The Mercury Communicator Unit (MCU) is a high performance peer-to-peer multi-operator station designed for critical communication in small to large-scale operations. The matrix-less architecture facilitates virtually unlimited scalability with each unit being able to simultaneously communicate with up to 64 endpoints and host up to 32 virtual panel applications. This single user operator station can also provide the unique ability to simultaneously communicate with operators residing within different security domains when used in conjunction with the Mercury Analog Voice Bridge.

The MCU facilitates a single-user operator station that can independently communicate with a vast number of other Mercury peer devices and SIP endpoints.  MLS is achieved through complimenting the Mercury system with a Mercury Interface Unit (MIU) equipment with a bridge card to facilitate communications from the MCU operator station across security classification domains in a certifiably protected manner.

The MCU is a form factor design, that is typically positioned on a desk or optionally mounted underneath as opposed to being rack mounted. The compact design means it can be used in virtually any environment to compliment and expand the communications for the solution at hand.
