Method and system for line status indicators using line side power

摘要: A power management circuit for use in a terminal interface device such as modem which converts available line side into usable by the to activate variety of status indicators. These indicators signaling off-hook device, low power, or presence excessive current. The draw from without placing burden on attached digital its source. Certain utilize flasher/oscillator circuits increase functionality providing frequency based pulse more accurately describe operating environment circuit. is additionally comprised voltage regulator which, when becomes operational, enabled and regulates current interfacing communication network. preferred embodiment further programmable hold sink enables incorporating be compatible with multiple networks having diverse specifications.
