Abstract
Description
Claims (2)
- RTIV로부터 시리얼 데이터를 받아 16-포인트의 캐리어리스 진폭/위상 신호로 변조시키는 16-CAP 변조부(1)와, 상기 변조부(1)의 출력을 4개의 동일한 신호로 출력하는 구동부(2)와, 상기 구동부(2)의 출력을 필터링하여 CAP 신호외의 고주파 신호를 제거하는 CAP 필터부(4), 상기 CAP 필터부(4)를 통해 출력되는 하향의 CAP 변조된 신호와 전화라인을 통하여 입력되는 상향의 QPSK 신호를 서로 간섭없이 합산/분리시켜 상기 전화라인상으로 전송하는 하이브리드 필터부(5)와, POTS 신호를 동일한 전화라인 상으로 전송하기 위해 CAP/QPSK 신호와 합산/분리시키는 POTS 스플리터(6)와, 상기 하이브리드 필터부(5)을 통하여 상기 POTS 스플리터(6)에서 분리되어 입력되는 상향 신호의 대역외의 신호를 필터링하는 QPSK 필터부(7)와, 상기 QPSK 필터부(7)의 출력을 복조하여 네트워크상으로 출력하는 QPSK 복조부(8)로 구성됨을 특징으로 하는 SWAN2망의 RT 모뎀장치.
- 제1항에 있어서, 상기 구동부(2)의 출력단에는 상기 구동부(2)의 출력을 증폭하는 증폭부(3)가 구성됨을 특징으로 하는 SWAN2망의 RT 모뎀장치.
