Upon detection of a foreign voltage fault the controller can deactivate the telephone service and initiate a test sequence to confirm the foreign voltage fault. If the fault is confirmed the telephone service remains deactivated and an operator of the digital network is notified. The device will improve the quality of service and save the cost of sending some one to investigate the fault. The operator can take proactive action once the device provides fault analysis and information remotely."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting foreign voltage faults in telephone customer premise equipment","description":"In general, in one aspect, the disclosure describes a digital network to telephone interface device having a controller capable of detecting foreign voltage faults without interrupting telephone servi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8494120","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
