Red Communications Switch SA-2112B(V)/STQ

The SA-2112B(V)/STQ Red Digital Switch system is designed to satisfy the U.S. Navy's requirement for providing secure switching of data, clock and discretes among cryptographic equipment, modems, digital communication terminals, teletypewriters, tape perforators and tape distribution equipment.

The system is comprised of a central secure digital switch, the SA-2112B(V)/STQ . The modular RDS replaces dedicated secure digital patch panels with a single automated switch providing remote user access, secure digital transmit, recieve capability and multiple net selection.

Two basic configurations of the central switch are provided: a standard SA-2112B(V)n/STQ, physically packaged in a six-foot cabinet, and a small configuration, SA-2112B(V)1/STQ, that is physically packaged in a smaller 32" cabinet. Common subassemblies are used in both configurations.

The switch architecture employs a non-blocking solid-state space division matrix for digital transmit and recieve signals, and a time division technique for switching discrete control and status signals. One centrally located Control and Status Panel (CSP) enables the operator to exercise complete control over all RDS functions. The CSP can be used to program line-net-trunk interconnections and eligibility data to the controller memory, display RDS interconnection status, isolate system faults.

This COMSEC-compatible design is operational on several platforms at the present time.
