야외 내각 팬 선반, 서지 보호기와 U3024BO을 지원하는 환경 제어 인클로저입니다. 야외 캐비닛은 서비스 제공 업체가 비용 효율적 등 ADSL 및 VDSL 등의 초고속 인터넷 서비스의 높은 밀도를 배포 할 수 있습니다..
U3024BO은 100Mbps(양방향 최고속도)의 트래픽 대역폭을 지원하는 DSLAM장비입니다. 이 장비는 광통신 및 이더넷 가입자 기반을 제공하는 네트웍에 적용가능합니다. U3024BO DSLAM 장비는 야외 캐비닛에 설치됩니다.
U3024BO는 VDSL2 모뎀을 통해 사용자가 장치에 연결됩니다. L2 이더넷 스위칭 기능 시스템은 작거나 중간 크기의 네트워크의 형태로 통합 할 수 있습니다. 시스템이 효율적으로 IGMP (인터넷 그룹 관리 프로토콜) 스누핑 같은 하드웨어 기반의 멀티 캐스팅 기능을 통하여 차세대 멀티미디어 응용 프로그램에 대한 핵심 요구 사항인 실시간 스트리밍 서비스를 지원합니다.
Ubiquoss 3024BO 시스템은 대역폭 관리 기능과 QoS(Quality-of-Service) 기능을 지원하여 기업 및 서비스 제공자에게 응용 서비스 또는 SLA(Service Level Agreement)에 따라서 차별화된 TPS서비스를 제공할 수 있습니다.
Ubiquoss 3024BO 시스템은 VDSL(Very high-data rate Digital Subscriber Line) 기술을 적용하며, 첨단 DMT 방식의 VDSL2 서비스 인터페이스를 구현하여 100/100Mbps 대칭 상/하향 전송 속도를 보장합니다.
Ubiquoss 3024BO 시스템은 Layer2 스위치의 기능을 가진 IP-VDSL로써 VLAN, Rate limit, 포트 트렁킹, 포트 미러링, IGMP Snooping, 패킷 필터링 등의 기능을 지원합니다. | |
