Abstract: A multi-functional mobile station (MMS) (610B) associated with at least one public land mobile network having switching circuitry implemented with a first cross-connect base-band switch system (370A, 370B) and a second cross-connect base-band switch system (365A, 365B). The first cross-connect base-band switch system (370A, 370B) is for selectably effectuating a first connection between an external receiver and at least one of the transceiver and the microphone of the MMS. The second cross-connect base-band switch system (365A, 365B) is for selectably effectuating a second connection between an external transmitter and at least one of the transceiver and the speaker (350) of the MMS (610B). The MMS (610B) is adapted to include one output node (335) for establishing the first connection and one input node (340) for establishing the second connection.

Abstract: A highly stable single chip crystal controlled oscillator with automatic gain control. An amplitude detector monitors the output of a crystal controlled oscillator amplifier and produces a feedback signal proportional to the output signal of the amplifier to ensure oscillation is induced at startup and that the amplitude of oscillation is limited to a preselected value during operation to conserve power consumption by the amplifier. The capacitor tank circuit connected to the input of the amplifier includes a voltage variable capacitor the voltage across which is initially established at manufacture to tune the oscillation frequency to a preselected value. The voltage across the voltage variable capacitor is also adjusted to compensate for temperature variations in the circuit.
