Abstract: A system and method for selectively muting a call of a wireless communication system. A first predetermined signal is received by the wireless communication system. The phone signal has a user signal associated with it. In response to the first predetermined signal, the wireless communication system pauses communication of the user signal to the end user while still maintaining the phone call between the wireless communication system and the conference bridge. In response to a second predetermined signal, the wireless communication system reinitiates communication of the user signal to the end user.

Abstract: A surge reset circuit (200) used to automatically reset a surge protection circuit within a telephone line interface circuit. A sensor (300) (e.g., a zenering device) advantageously generates a voltage level representing current draining out of the transient voltage suppression portion of the surge protection circuit after a transient energy surge. If the current is draining, which may indicate a potential lockup situation, feedback circuitry (305) generates a reset feedback signal that is provided to a cutoff device (330). The cutoff device, in response to receiving the feedback signal, disables a current limiter portion of the surge protection circuit to reduce the current draining from the transient voltage suppression portion. As the current level is reduced, the transient voltage suppression portion will reset when the current drops below a threshold value or is substantially eliminated. As a result, the feedback circuitry removes the reset feedback signal from the cutoff device to re-enable the current limiter (34).

Abstract: An input N-plexer filter stage is susceptible to receive surge energy via an input conductor, when the surge energy occurs. A high-pass filter included in a diplexer filter stage applies a radio frequency (RF) signal in a signal path between the input N-plexer filter stage and an output of a Data Over Cable Service Interface Specification (DOCSIS) transmitter stage. A low-pass filter included in the diplexer filter stage couples a surge suppressing threshold device to the signal path to dissipate the surge energy in the surge suppressing threshold device, when the surge energy occurs. The low-pass filter has a cut-off frequency that is lower than a normal operation frequency range of the RF signal. The low- pass filter isolates the surge suppressing threshold device from the signal path in normal operation frequency range of the RF signal, when no surge energy is applied.

Abstract: A frequency selective transient voltage protector (FSTVP) circuit that may be used in connection with a communication line over which POTS and DSL service may be simultaneously provided. The FSTVP circuit attenuates high frequency transient voltages that exceed a predetermined voltage level, while permitting low frequency, generally high voltage signals (e.g., ring signals) and high frequency, low voltage signals (e.g., DSL signals) to pass with little or no attenuation. The FSTVP circuit comprises a frequency selective network (that comprises a frequency discriminator and a voltage discriminator) connected to an overvoltage protection device that shunts any high frequency transient voltages thus protecting devices connected downstream along the communications line from damage. The frequency selective network is tuned to gate the overvoltage protection device when the frequency and voltage of a signal present on the communication line exceed predetermined values.
