Abstract

2선식으로 CVSD음성 신호 및 데이타를 교환기와 통신하기 위한 디지탈 전화기는 미리 내장된 프로그램에 응답하여 호의 통신에 필요한 시그날링 및 프로토콜을 처리하여 전화기내의 각부를 동작시키기위한 제어신호를 인가하는 제어수단과, 상기 제어수단의 제어신호에 응답하여 2선식 전화라인과 전화기간에 음성신호 및 데이타가 송수신 되도록 인터페이싱 하는 인터페이스와, 상기 인터페이스와 연결되며 상기 제어수단의 제어신호에 응답하여 상기 라인을 통해 접속되어 있는 교환기와 시그날링을 송수신 하기위한 프로토콜 콘트롤러와, 상기 인터페이스와 연결되며 상기 제어수단의 제어신호에 응답하여 CVSD코텍으로부터 출력되는 음성신호를 채널에 실어주거나 상기 인터페이스로부터 수신되는 음성정보를 변환하여 상기 CVSD코텍으로 인가하는 체널 인터페이스와, 상기 채널 인터페이스와 상기 전화기의 핸드셋간에 연결된 코텍으로 구성된다.The digital telephone for communicating CVSD voice signals and data with the exchange in two wires includes control means for processing signaling and protocols required for call communication in response to a pre-built program and applying control signals for operating each part of the telephone. An interface for interfacing a two-wire telephone line with a voice signal and data during a telephone period in response to a control signal of the control means, and connected with the interface and connected through the line in response to a control signal of the control means. A protocol controller for transmitting and receiving signaling with an exchanger, and a voice signal output from a CVSD codec connected to the interface and outputting a voice signal output from a CVSD codec in response to a control signal of the control means or converting voice information received from the interface. Approved by CVSD Coatec A channel interface and a cortex connected between the channel interface and the handset of the telephone.
