Black Communications Switch SA-2112A(V)/STQ

The SA-2112A Black Analog Communications switch (BCS) extends the SA-2112 switching technology to meet other communications switching requirements. In shipboard applications, the switch provides automated switching between modems, voice and data encryption devices and radio circuits. The SA-2112A replaces radio transmitter and receiver transfer switchboards and patch panels (E.G. SB-863/SRT, SB-2727, SB-3833, SB-82, SB-83). Implementation of the SA-2112A provides significant advantages in automated switching, weight, space, reliability and maintainability over the switchboard implementation. Two basic configurations of the SA-2112A are provided, A standard SA-2112A, physically packaged in a six foot cabinet, and a small ships configuration, SA-2112A(V)1, that is physically packaged in a smaller 32" cabinet. Common sub-assemblies are used in both configurations. These sub-assemblies are also common with the SA-2112 Secure Voice Switch (SVS). A nonblocking solid state division matrix is used within the switch architecture for transmit and receive signals. Discrete and control and status signals are multiplexed through the switch. A front Control and Status panel (CSP) provides the operator interface to exercise complete control over all BSC functions. The CSP can be used to program independent receive and transmit interconnections, display current interconnection status, isolate system faults, and to monitor all circuits by using the panel-mounted handset. Commonality with the SA-2112 SVS in panel operation is maintained. The SA-2112A(V)1 is designed to extend SA-2112 technology to ship classes with less demanding requirements. This configuration is packaged in a smaller thirty-two (32) inch high cabinet that can be rack mounted. The configuration retains all of the key performance and operational characteristics of the large cabinet SA-2112A. The cards, power supplies, and battery/battery conditioner are common with the large cabinet configuration.
