An electronic alarm is disclosed for use in a moving vehicle which generates ultrasonic sound for preventing animals from moving into the path of the vehicle. The device includes a simplified driver circuit for generating electrical impulses in the form of square waves having constant peak-to-peak voltages. The driver generates the square waves with periodic, sequentially increasing wave frequencies followed by sequentially decreasing wave frequencies. A coupling transformer converts the square waves into electrical sine wave voltages having high peak-to-peak voltages to cause a piezo-electric transducer to emit intense, ultrasonic sounds of periodically increasing frequencies followed by periodically decreasing frequencies simulating the warble effect of a siren without excessive heating and premature failure of the transducer. The ultrasonic warble effect confuses the animal to prevent inadvertent movement by the animal into the oncoming vehicle's path without injury to the animal.

An interface between mobile telecommunication stations and trunks that link with communication carriers of various media comprises station channels (11, 12, 13, and 14) that connect to telecommunication stations, trunk channels (1, 2, 3, and 4,) that connect to trunks that link to communication carriers, software code executable for interrogating the trunk channels for availability, software code executable for determining the communication medium or network of least cost, and software code executable for routing the telephone call from one of the station channels to the available trunk channel linked to the communication carrier having the medium or network of least cost. If the routing is to a trunk line linked to satellite communications, the interface selects the coast earth station of least cost based upon the location of the ocean going vessel, the destination of the call, and other rate considerations. Call progress through the interface is supervised such that the call is terminated after an extended period of ring no answer, busy, dead air, etc. The invention also provides for automatic leveling and creates a detailed call record of all calls originating from the ship for billing purposes.
