A power controller for power sourcing equipment in a distributed power network provides power down policies and priority in the event of a power supply failure. The power down priority and policy permits implementation of a rapid decrease in the power demand of the distributed power network to avoid overload of a backup power supply. The priority may be derived based on the relative position of port information in a linked list. Devices associated with a high priority can remain powered in response to a main power supply failure, while lower priority devices can be rapidly powered down to reduce the overall load demand on the backup power supply. The ability to configure ports on the basis of priority and available policies provides a flexible and simple implementation of a response in the event of a main power supply failure.

The PBX system includes an analog to digital, and digital to analog, (A/D) conversion where the sample size and the sample rate are selectively adjustable. The A/D structure includes registers which hold values indicating the sample size and the sample rate for the conversion. When the A/D structure is configured, the A/D structure reads the values in the register and configures itself to the sample rate and sample size indicated by the registers. When the sample size and sample rate is to be changed, the values in the registers are changed and the A/D structure is reconfigured.

A bridge board connects a TMS470 processor evaluation module and a TMS320C54XX processor evaluation module. The bridge board performs translation of signal formats on both of the boards and also synchronizes the signal formats on both boards so that both boards are able to operate together. With this bridge board, and its specific connections to both of the evaluation modules, a single workstation, preferably connected to the TMS470 module is able to not only control the TMS470 module but also the TMS320 module. Software for the TMS320 can be loaded from the workstation through the TMS470 module, through the bridge board and into the TMS320 module. The software in both of the evaluation modules can then operate and interact with each other through the bridge board.

A telephone set of a telephone system is provided with an infrared interface. This infrared interface is able to communicate with an infrared port on a local computer. The computer is configured to send data to the infrared port, and receive data from the infrared port, in the same manner as if the computer was sending and receiving data over a telephone system. The telephone circuitry in the telephone system receives the infrared data and converts the infrared data into a format for transmitting across the telephone system.

A connector assembly for protecting against cable discharge with respect to static charges that may accumulate on cables and other conductors. The connector assembly comprises a modular plug that mates with a modular jack. The modular jack comprises a plurality of resilient contacts that connect to rigid contacts on the modular plug when the plug and jack mate. The modular jack also supports a grounding conductor such that the jack contacts connect to ground when the jack and plug are unmated. As the plug and jack begin to mate, the jack contacts connect a ground potential to the plug contacts, thereby discharging to ground any static charge that may be stored on the cable. As the jack and plug continue to mate, the plug contacts disconnect the jack contacts from the grounding conductor. When the jack fully mates with the plug, cable conductors connect to an electronic circuit via the jack and plug contacts. The grounded contacts of a jack will steadily prevent charges from accumulating on cables or other conductors connected to the jack as long as the jack remains unmated. In a first embodiment, an electromagnetic shield, which connects the grounding conductor to a ground potential, covers the jack body. In a second embodiment, each of a plurality of grounding conductors connects to a different jack contact.

Apparatus and methods for preventing cable-discharge damage to electronic equipment

According to the invention, an Ethernet system and method of using an Ethernet system is provided including a network side device (a hub/switch/concentrator), and a plurality of end devices (either a standard end device powered locally or a system powered device), connected to the hub/switch. The system powered devices have circuitry for indicating the system power need to the hub, which has a power source for selectively supplying system power over the Ethernet. A stimulus device associated with the network device sends a stimulus signal over the network connection lines during a detection phase. The need for power is signaled by an indication device associated with the system powered end devices, providing an indication signal in response to the stimulus signal. A detector associated with the network side detects the indication signal thus triggering the power source to supply system power to each of the end devices that is a system powered device and not to each of the end devices that is a standard device.

A plurality of audio sources are provided in a Private Branch Exchange (PBX) and monitored to determine if audio is available from any of the sources. Once an audio source with an audio presence has been found, that audio source is connected to the PBX and the PBX uses the audio from that source to provide audio-on-hold to the telephone users at that PBX. The audio coming from that audio source is substantially continuously monitored. When it is determined that this particular audio source is no longer providing audio, this particular audio source is disconnected from the PBX network and another audio source having an audio presence, is connected instead.
