Ubiquoss 3024B 시스템은 광 가입자 망 및 이더넷 기반 네트워크의 가입자 집선 구간에 적용되어 물리적 계층에서 100M급 VDSL2서비스를 제공하는 고성능의 스위치 기능을 포함한 VDSL2 집선장치 입니다. Ubiquoss 3024B 시스템은 국사 및 아파트 MDF실 또는 옥외용 함체에 위치하여 트래픽을 집선, 상위 가입자 집선스위치로 전달하며, 이와 반대의 역할을 담당합니다.
Ubiquoss 3024B 시스템은 VDSL2 모뎀을 통하여 가입자 단말과 연결되며, 고속 및 다양한 Layer2 이더넷 스위칭 기능을 통하여 소형 및 중형 네트워크에 적용이 가능합니다. 또한, 하드웨어 기반으로 제공되는 IGMP(Internet Group Management Protocol) snooping 같은 멀티캐스트기능은 IP-TV 등의 실시간 Streaming 서비스를 제공하여 차세대 멀티미디어응용서비스를 효율적으로 제공할 수 있게 합니다.
Ubiquoss 3024B 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 3024B 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 3024B 시스템은 Layer2 스위치의 기능을 가진 IP-VDSL로써 VLAN, Rate limit, 포트 트렁킹, 포트 미러링, IGMP Snooping, 패킷 필터링 등의 기능을 지원합니다. |
