MVD5048-LR is the high performance switch which uses Ikanos Chipset for VDSL line coding and can transport the traffic at the speeds of up to 58Mbps downstream and up to 20Mbps upstream over copper twisted pair up to 3km.MVD5048-LR mountable on the standard 19 inch rack features compact design, high scalability according to the number of subscribers, advanced plug-and-play functionality, easy installation and handy Ethernet LAN configuration capability. MVD5048-LRs built-in LAN switch supports Ethernet base Layer 2 switching function, and provides 48 subscriber ports, 4 10/100Mbps or Giga GBIC uplink ports. It also provides Ethernet port and console port for management purpose. MVD5048-LR supports such additional Layer 2 functions as STP (Spanning Tree Protocol), Link aggregation, port-based VLAN and 802.1Q. Its stacking function capable of configuring multiple systems with one IP address provides the means of convenient system management. MVD5048-LR supports powerful packet filtering (Layer 2 to Layer 4) functions and QoS for service security and quality improvement. NetBEUI/NetBIOS filtering, DHCP filtering and MAC address restriction per port can be realized through such packet filtering function. Data rate: max. 58Mbps(downstream)/20Mbps(upstream) Service distance: up to 3 Km (AWG 26) High quality data communication Stable data transmission using DMT (Discrete Multi-tone) line coding method Asymmetric/Symmetric transmission Rate Adaptive transmission UPBO (Upstream Power BackOff) function Radio Band Notching function ADSL band and optional band enable/disable Slow/Fast channel support for burst error control Powerful Layer 2 Ethernet switching function Various uplink port:100Base TX, 100Base FX, GBIC Various management tools: Console, Telnet, SNMP Spanning Tree Protocol supported Port-based VLAN/Tagged VLAN(802.1q) MAC address restriction per port DHCP filtering, NetBEUI/NetBIOS filtering Scalability Multicasting (IGMP Snooping/IGMP querier) function Spanning Tree protocol supported QoS and 802.1p supported Powerful packet filtering (Layer 2 ~ Layer 4) Link aggregation Easy installation: Plug & Play Broadcast Storm Control
