摘要： Apparatus and methods for adaptively, reliably, and accurately measuring the duration of an alerting or other signaling tone. A tone detector in accordance with the principles of the present invention accurately measures a duration of a tone burst (i.e., tone pulse) using a long frame length DFT and a short frame length DFT. Based on information obtained by the short frame length DFT, the long (i.e., standard) frame length DFT may be interrupted and reset to begin a new frame of data synchronized with the start of the next short frame corresponding to the processing by the short frame length DFT to minimize noise in the processing by the long frame length DFT and to greatly improve the resolution of the measurement of the duration of a particular tone to correspond to the lengths of the short frames used by the short frame length DFT. If desired, after a tone is initially detected, the frame length of the short frame length DFT can be iteratively reduced to increase a resolution of the measurement of a tone start time and a tone end time used to determine the duration of the detected tone burst.

摘要： A method and apparatus to perform a real-time drift correction of a remote handset's local oscillator in a digital cordless telephone. The remote handset begins in a standby (sniff) mode. The remote handset periodically wakes from a sleep mode and goes into a normal link verification mode. Once in the link verification mode, the remote handset enters a time division duplexing (TDD) mode and attempts to establish a link with a base unit based on the timing of the TDD data frame. After the remote handset establishes a link with the base unit, the remote handset requests a security word from the base unit. Upon receiving the requested security word, the remote handset determines if the requested security word matches a security word of the remote handset. The remote handset implements a software frequency adjustment of its local oscillator. Once per frame, the remote handset enters a timing recovery state where the current state of the frame is compared with a previous state. When the cumulative timing slip is greater than a designated threshold, a frequency adjustment is made. During this exchange of commands between the remote handset and base unit, the remote handset continuously adjusts its local oscillator to achieve frequency alignment within, e.g., 1 part per million (ppm). Alternatively, frequency alignment may be achieved to a specified value.

摘要： A call related information detector/receiver system which is capable of downloading call related information received at that device to another call related information detector/receiver system remote from the system which initially received the call related information, back over the telephone line. Thus, a remote user while away from the home or office can receive and synchronize call related information at a system other than the one which initially received the call related information. Thus, a remote user can update a local call related information system and review past callers to their home or business telephone at their leisure. Upon establishment of a telephone call between customer premises equipment respectively associated with the two relevant call related information detector/receiver systems, a remote call related information system will request download of call related information logged from another call related information system using the established telephone call. In the disclosed embodiment, the request signals are encoded with DTMF tones, which the receiving call related information system monitors for. Upon acceptance of a request to transmit logged call related information, previously logged call related information is retrieved from its log, formatted for transmission together with suitable header information such as the identity of the transmitting call related information system, and FSK modulated for transmission back over the telephone line. Preferably, the speaker or earpiece of off-hook customer premises equipment will be muted or suppressed during transmission of the data corresponding to the call related information. The particular call related information transmitted may be particularly or generally requested by the remote call related information system, either by pre-stored commands based on a power up configuration of the requesting call related information system, and/or in response to a direct command input by the remote user using DTMF tones.

摘要： A telephone or adjunct Caller ID device adaptively stores Caller ID data based, for example, on a handling status of an incoming call. In a particular example, a telephone or Caller ID device includes a memory adapted to store Caller ID data associated with an incoming call, and a processor adapted to affect storage of the Caller ID data based on a status of the incoming call, such as whether the incoming call is answered. In an alternative embodiment, a method of receiving an incoming telephone call includes the steps of receiving Caller ID data associated with the incoming telephone call, evaluating a status of the incoming telephone call, and making a Caller ID storage decision based on the status of the incoming telephone call. The decision may be based on handling of the incoming telephone call, such as whether the incoming telephone call is answered, or whether it is answered by a person. The decision may be made proximate in time to the receipt of the incoming telephone call, or in response to a circumstance, such as in response to receipt of an indication that the memory is more full than a threshold, or in response to user input. For example, the decision may be made in conjunction with other storage decisions regarding other Caller ID data in response to the circumstance.
