Abstract

This disclosure is directed to techniques for facilitating return path compliance in networks. A device, such as an optical network terminal (ONT), may, for example, buffer a digital representation of an upstream analog signal to facilitate return path compliance specified by a Data Over Cable Service Interface Specification (DOCSIS) 3.0 standard. The ONT may comprise a first conversion module that converts an upstream analog signal into a corresponding digital signal and a signal detection module that determines whether the upstream analog signal represents a valid upstream communication. The device may further comprise a buffer that buffers the corresponding digital signal while the signal detection module makes the determination, a second conversion module that converts the buffered digital signal into a reconverted upstream analog signal upon the determination that the upstream analog signal is valid and a laser that transmits the reconverted upstream analog signal via a fiber optical cable.
