본 논문에서는 이더넷 패킷과 TDM 신호를 동시에 수용할 수 있는 통합전달 시스템을 설계 및 구현하였다. 구현된 시스템은 하나의 장치에서 MPLS 기반의 L2 VPN 서비스, 프리미엄 멀티미디어 서비스 및 TDM 전용회선 서비스를 동시에 제공할 수 있다. 또한 서킷 네트워크 기반의 보호/복구 기능을 제공함으로써, best effort 형식의 기존의 이더넷 망에서는 가질 수 없었던 높은 신뢰성을 제공할 수 있다는 장점을 가진다. 제안된 서비스를 제공하기 위해서 이더넷 패킷과 TDM 신호에 대한 기존 망과의 연동성 시험이 성공적으로 수행되었다.
