A Charging unit for a cellular telephone is provided with having means for connection to an electrical power source and a charging circuit for delivering a charging current to a battery pack or the cellular telephone itself, if the cellular telephone includes an internal energy retaining mechanism (e.g., charge storage device such as a battery). The charging unit further includes a plurality of electrical contacts in electrical communication with the charging circuit. Finally, the invention includes at least one user-selectable switch and at least one electrical contact in electrical communication with the at least one user-selectable switch. In accordance with another aspect of the invention, a cellular telephone is provided, wherein the telephone includes a sensing circuit configured to detect the presence of a charging unit. It further includes a circuit configured to identify from the charging unit a designated number to which to forward incoming calls to. Specifically, once the telephone senses that it has been placed on a charging unit, it then looks to the circuit configured to identify a designated number to forward calls to. Preferably, this is accomplished by one or more inputs provided from a user-selectable switch on the charging unit. Finally, the telephone includes a number identifying circuit electrically connected to the at least one input and configured to identify a designated number to transmit to a cell site as a call-forward number. This may be accomplished, for example, by a CPU accessing a number storage memory.

A cellular telephone, in its most preferred embodiment, performs a method for notifying a digital cellular telephone user of an imminent communication disconnection. The preferred method includes, at least, generating at least one condition indication representative of at least one communication condition, analyzing the condition indication, determining whether a communication disconnection is imminent, enhancing quality of received communication signals when possible, and notifying the user of an imminent communication disconnection. Exemplary condition indications include, at least, continuous count and rate indications of frame checksum errors, insufficient quality frames, symbol errors, and chip errors, output power level indication, received signal strength indication, soft handoff status indication, other pilot signal indication, and current pilot signal strength indication. One exemplary analysis technique of determining when a communication disconnection is imminent includes evaluating whether any of a set of condition indications violates a predefined threshold indication, while other exemplary analysis techniques include evaluating whether fixed or historically adaptive combinations of condition indications violate run predefined thresholds, and evaluating combinations of condition indications weighted according to the degree of threshold violation. The process further uses a memory flag in a delayed redundant comparison before enabling a warning, examples of which include visual, sensory, and audible notification methods, including adding generated noise to the received audio signal. Alternate methods of the invention include notifying a user of an imminent inter-system handoff or an imminent change in communication mode.

A modular plug and cover therefor includes a plug body having an insert portion and a rear portion having an indentation. The rear portion receives a cable for connection to the insert portion. A cover for the modular plug is of a substantially rectangular configuration having an open end fitting over the rear portion of the plug body. The cover portion is engageable with the plug body such that an enclosed space is defined between an end of the rear portion of the plug and an opposing inner wall of the cover. The cover is further provided with a tapered projection on an inner surface thereof which corresponds to the location of the indentation and an access opening through which a cable connected to the modular plug is passed. The cover portion may also be engaged with the plug in an inverted state to change the direction in which the cable is oriented.
