Abstract
A signal transfer point (STP) includes a plurality of control and sense points that enable the STP to collect sensory information of all types and to provide control of individual pieces of equipment. The STP is operable to generate reports that record the activity of external devices that are either being monitored or where operation is being controlled. Each sense and control point board provided within the STP is operable to provide up to 32 sense points and twenty-four control points in one described embodiment of the invention. The sense points are operable to detect either a low voltage condition or a high voltage condition. The sense points are operable to monitor up to 60-volt signals and thus may monitor telecom voltage levels for US (48 volts) as well as European systems (60 volts). The sense points are optically isolated to eliminate the possibility of unwanted current flows. The control points are relays capable of handling up to a 60-volt difference in potential in its switching operations.
