Filed: 2001-10-31
Abstract: PURPOSE: An apparatus and a method for preventing a call block of a voice mail box board are provided to transmit a message for canceling a call to a scenario task and cancel the call relating to the corresponding channel when sensing a CG(congestion) tone, thereby preventing a call insubordination phenomenon occurring when performing a hook-on by a subscriber. CONSTITUTION: A DSP(Digital Signal Processor)(110) senses a DTMF(Dual Tone Multi Frequency) signal and a tone signal among signals incoming through a channel connected by a call processing board. An interface stores the DTMF signal and the tone signal sensed by the DSP. A DTMF task(121) performs a polling of the interface at every polling period. The DTMF task records information on the DTMF signal when the DTMF signal is inputted and produces the DTMF signal detection message. A tone task(123) performs a polling of the interface at every polling period. When the tone signal is inputted, the tone task discriminates whether it is a CG tone produced by hooking on a handset while talking over the telephone. When it is a CG tone, the tone task produces a call cancellation message. A message queue(125) stores a DTMF detecting message and a call cancellation message received from the DTMF task and the tone task. A scenario task(127) performs a polling of the message queue at every polling period. When a call cancellation message is inputted to the message queue, the scenario task cancels the call relating to the corresponding channel by using a channel number included to the call cancellation message.

Title: Method and system for down-converting an electromagnetic signal
IPC: H04B1/04
Filed: 1999-10-20
Abstract: Methods, systems, and apparatuses for down-converting an electromagnetic (EM) signal by aliasing the EM signal are described herein. Briefly stated, such methods, systems, and apparatuses operate by receiving an EM signal and an aliasing signal having an aliasing rate. The EM signal is aliased according to the aliasing signal to down-convert the EM signal. The term aliasing, as used herein, refers to both down converting an EM signal by under-sampling the EM signal at an aliasing rate, and down-converting an EM signal by transferring energy from the EM signal at the aliasing rate. In an embodiment, the EM signal is down-converted to an intermediate frequency (IF) signal. In another embodiment, the EM signal is down-converted to a demodulated baseband information signal. In another embodiment, the EM signal is a frequency modulated (FM) signal, which is down-converted to a non-FM signal, such as a phase modulated (PM) signal or an amplitude modulated (AM) signal.
