    摘要： A cordless modem comprises a radio pair interfaced to a standard data/fax modem which allows a user of a personal computer to wirelessly connect to a telephone line. One end of the radio pair is a remote unit interfaced to the modem contained within the PC while the other end is a base unit connected to a standard telephone wall jack. The base unit can selectively discriminate and adjust for signals received from a telephone voice handset or data signals received from the cordless modem remote unit. Upon receiving an off-hook signal or an incoming call signal, the base unit identifies the type of data (i.e., voice or computer modem data) and adapts accordingly by placing an FM modulator in either of a narrow band deviation or a wide band deviation covering the required range of the particular signal combined with local echo. That is, when voice data is present, a low deviation, narrow filter combination is selected. If, on the other hand, the computer data from the cordless modem is detected, a higher deviation, wider bandwidth filter is selected. In addition, the remote unit switches a pre-detection filter from one mode to another depending on whether it is connected to a computer modem or to a voice handset. Security from eavesdroppers as well as the mitigation of signal fading is provided by overlaying a pseudo-random number (PN) code on the FM modulated signal.

    摘要： In an illustrative embodiment, the AC power line network simulator includes an enclosure for containing elements of the system. An AC coupling network coupled to the network simulator implements the functions relating to a particular simulation. A distribution panel connected to a power feed distributes power and includes outgoing circuits and circuit breakers for protecting the outgoing circuits. A plurality of outlets are connected to the breakers of the panel. Through the use of the simulator, with the AC coupling network, simulation of an AC power line network, such as measuring electrical signals, recording electrical signals, simulating electrical signals and inserting electrical signals, can be easily performed. The measured, recorded, simulated and inserted signals correspond to electrical characteristics of elements found in an AC power line network, and can be stored for later analysis. In addition, once simulation information has been stored, it can be reproduced as desired.
