The invention is directed to an optical network terminal (ONT) for use in a passive optical network (PON) that provides reliable battery status reporting and, optionally, remote monitoring and configuration of an uninterruptible power supply (UPS) unit. In particular, the UPS unit provides power to the ONT via a power line and transmits data to the ONT via the power line. Generally, the described invention supports one-way or two-way communication of status, alarm, and configuration signals using a single power line. Specifically, such signals may be transmitted over the power line by inserting a carrier frequency, such as a carrier frequency of approximately 1 MHz, onto the power line. In this manner, the invention may provide a simple battery status monitoring system while also reducing the cost of installation.

Network interface device communication via power line

A telecommunications chassis, module, and repeater circuit for use with signals having data rates including STM-1 (155.52 megabits per second) are disclosed. The chassis provides structures for establishing shielding and heat dissipation for the circuitry modules it contains including an outer and an inner Faraday box with an integrated ventilation pattern for circulating air. The module provides its own structures for establishing shielding and heat dissipation including a Faraday box and a ventilation pattern. The repeater circuit provides the ability to bridge a data signal between a monitor jack of one device and a higher signal level input jack of another device through multiple amplification stages and circuit board structures. The telecommunications chassis, module, and repeater circuit can be used in conjunction.
