Abstract (en)
[origin: WO9318605A1] A hybrid fiber in the loop telephony system. The system provides for highly reliable telephone service, even during electric utility company power failures. The system generally includes an ONU (4) for conversion of optical signals to electrical, digital signals. The electrical, digital signals are transmitted to a subscriber location (12). The subscriber location utilizes an NID (20) having a ring generator (306) and analog-to-digital conversion equipment (304). Mechanical features of the system are also disclosed.
