摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A card, particularly a digital line card is provided for use with a chassis having a slot for receiving the digital line card. The chassis has an Ethernet bus for receiving packets from the line card and has a power supply and power strip for supplying power to the line card. The line card includes a public switched telephone network (PSTN) digital line input/output interface for sending digital signals over the PSTN and for receiving digital signals from PSTN. A line card control processor is connected to the digital line input/output interface. An Ethernet input/output is provided for sending packets over a local network corresponding to signals received from the telephone line and for receiving packets from the local network and forwarding received signals to the digital line input/output interface. The Ethernet input/output has a controllable backplane interface to the Ethernet bus including a switch normally active to direct data flow between the line card and the Ethernet bus, an Ethernet transceiver connectable to an Ethernet network, and an Ethernet link signal detector for detecting an Ethernet link signal at the Ethernet transceiver and deactivating the switch to isolate the line card from the Ethernet bus and to force data flow through the Ethernet transceiver. The card may also be part a network system with a chassis having a backplane Ethernet bus.

摘要： A transformer unit includes a first isolation transformer, a second isolation transformer and a power transformer. A single package incorporates the first isolation transformer, the second isolation transformer and the power transformer. A plurality of connection pins provide connections to the first isolation transformer, to the second isolation transformer and to the power transformer. A process is also provided for connecting transmission lines to a network device including providing transmission lines carrying an electrical supply current, sufficient to power the network device, concurrently with a network data signal. The single unit has the first integrated isolation transformer the second integrated isolation transformer and the power transformer. Some of the transmission lines are connected to the first isolation transformer to isolate transmission signals on the sending transmission lines from a transmitter of the network device. Some other transmission lines are connected to the second isolation transformer to isolate transmission signals on the receiving transmission lines from a receiver of the device. Within the single unit each of the first isolation transformer and the second isolation transformer are connected to the power transformer. The power transformer is used to supply power to the circuit board of the network devise at a potential which is reduced compared to a potential of said transmission lines carrying the electrical supply current.
