Communication apparatus using telephone network
First Claim
1. A communication apparatus coupled to a telephone network, comprising:
- a plurality of switches that switch based on a transmission/reception state;
a mode detector that determines whether an input signal is one of a voice signal and a data signal;
a first buffer that receives the input signal;
a generator that receives the input signal and outputs a first prescribed signal when the voice signal is received;
a first switch for connection to a telephone;
an indicator that receives the data signal and indicates when the data signal is received by performing at least one of illuminating a light and generating a second prescribed signal;
a second buffer, wherein the second buffer is connected between the generator and the first switch, wherein the mode detector controls the second buffer to transmit the first prescribed signal and the voice signal to the first switch when the input signal is received, and wherein the mode detector controls the first buffer to transmit the data signal to the indicator when the input signal is received;
a modem controller connected to the first buffer that at least one of receives and transmits the data signal; and
a data circuit terminating equipment (DCE) controller that controls the plurality of switches based on the transmission/receptive state, and wherein the DCE controller receives the data signal from the modem controller.

Abstract
A communication apparatus for use with a telephone network is provided that includes a DCE controller that controls first and second switches to convert modes based on a transmission/reception state. A mode detector determines whether an applied signal is a voice signal or a data signal. First and second buffers are enabled based on a detection signal from the mode detector to respectively transmit a ring signal or the data signal. A modem controller receives an output signal of the second buffer through the second switch. The DCE controller can receive and apply to an internal processor the output signal from the second buffer via the MODEM controller. Further, an indicator unit that receives the output signal of the second buffer illuminates a light or generates a beeping sound for notification of a received dated signal. Alternatively, a ring generator generates a ring signal for a telephone for a received voice signal. Thus, the communication apparatus enables a user to determine whether to use a telephone set or a facsimile machine or the like, for telephone reception by providing indications that identify the kinds of incoming phone calls.
