ABSTRACT:
A electrical power control mechanism ensures start-up of all telecommunication devices (repeaters and a remote terminal) along a span-powered wireline. Input voltage start-up thresholds of power control circuits at the devices are higher than the steady-state voltage across the repeater closest to the span supply, when the span voltage is at a minimum DC wireline voltage that sustains operation of all devices. The maximum input voltage start-up threshold of a device is less than the maximum voltage that could be applied during start-up, and the remote terminal has an input voltage start-up threshold value higher than that of any repeater. The maximum standby current of each device is specified, and input power is limited to its steady state maximum during start-up.
