Output Transformer - Transformer which matches power output of an amplifier to impedance of a load. Outside Link - A link to a lowest level outside node. Outside Node - A node which is participating in PNNI routing, but which is not a member of a particular peer group. Overbooking - A VBR process used to increases total link capacity by a factor. Overcurrent Protection - Protection of power supplies, conductors, and connected equipment from excessive flow of input or output current, including the short circuited current.
Overload produces distortion.
Overload Protection - A circuit breaker or mechanical fuse which opens when the current is greater than that which the equipment has been designed to carry. Overload Rating - Some load in excess of the nominal rating, which a device can carry for a specified length of time without being damaged. Overtemperature Protection - Protection of the power supply or parts of it against temperatures exceeding specified values. Overvoltage Relay - Alarm relay which operates when voltage across it exceeds a preset level.
