ALLNET ALL1268M VDSL2 8 Port Master DSLAM Switch - Access Point - WLAN 89095 Copper Wire - 1 Gbps - Amount of ports: - HTTPS - RMON - SNMP - TCP/IP - Ethernet - WLAN - xDSL - Switch - Wireless - RJ-45 - Managed - Internal - Rack module - 19 U ALLNET ALL1268M. Switch type: Managed, Switch layer: L2/L3. Basic switching RJ-45 Ethernet ports type: Gigabit Ethernet (10/100/1000), Basic switching RJ-45 Ethernet ports quantity: 8. Networking standards: IEEE 802.1D,IEEE 802.1Q,IEEE 802.1ad,IEEE 802.1p,IEEE 802.1s,IEEE 802.1w,IEEE 802.1x,IEEE.... Rack mounting, Form factor: 19U 8 Port VDSL2 Master Switch for leased lines via 2-wire connections up to a length of 2500 meters and a bandwidth of 100 Mbit/s (depending on length)The ALLNET ALL1268M is a VDSL2 IP DSLAM, which provides up to eight 100 Mbit/s network connection via a 2-wire copper cable. Thus, an existing two-wire cabling in the building for high-performance data services such as Internet access, video-on-demand, IPTV, Voice over IP, video conferencing, telemedicine, and more are used. If the number of participants in the network increases, you may connect two ALL1268M via the integrated uplink gigabit Ethernet to each other. Alternatively, several ALL1268M can be combined via a LAN switch, which further increases the port number. The ALL1268M VDSL2 Master Switch is an ideal solution for providing cost-effective, high-performance broadband/multimedia networks for MTUs (multi-tenant units) and MDUs (Multi-Dwelling Units) such as hotels, schools, hospitals, etc. Key features and advantages:The 100 Mbit / s symmetrical for up to eight two-wire lines:The ALL1268M supports a symmetrical VDSL2 bandwidth of up to 100 Mbit/s when the cable length does not exceed 300 meters. With lower bandwidth cable lengths of up to 2600 meters have to be bridged. Jumbo frames up to 9 kilobytes:In Ethernet networks jumbo frames were originally packets with more than 1500 bytes of payload. However, each data packet has to be processed individually by the network hardware and software and can be checked for errors. Due to the increased frame size of 9000 bytes, the same amount of data are transferred with less effort. This reduces the CPU load and increases the throughput. EEE 802.1q Q-in-Q VLAN for performance & security:The VLAN feature in the ALL1268M makes the data communication quickly and safely. VLAN is used to isolate traffic between different users and thus ensure better security. Limiting the broadcast traffic within the same VLAN broadcast domain also enhances performance and guarantees certain bandwidths for the individual client. IEEE 802.1x:This port-based Network Access Control function is provided for secure access to wireless network clients and their authentication available when the ALL1268M is used as a central base for connection of wireless LAN access points. Spanning Tree:For mission critical environments with multiple ALL1268M redundant backup paths can be configured, so that traffic is distributed in the event of a failure of a fail-over switch. Thus, a function of the network is always guaranteed. IEEEE 802.1p QoS (COS) with four priority queues:The QoS (Quality Of Service) feature provides four internal queues with which the data packets of different classifications are assigned. High priority packets such as video and voice data is transported with less delay and lower latency than packets with low priority. This is essential for video and voice quality. IGMP Snooping:IGMP Snopping supports up to 256 multicast groups for VOD (video on demand) and video conference and Internet games application. HTTPS (SSL) Web Access:Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL protocol to provide encrypted communication and secure identification of network servers. HTTPS connections are often used for payment transactions on the World Wide Web and for sensitive transactions in corporate information systems. SNMP MIB Support: SNMP v1/v2c/v3 Management and trap function:Support MIB tables: MIB-II (RFC 1213), Bridge MIB (RFC 1493), Ethernet-like MIB (RFC 1643 and RFC 2665), Private MIB, USM-MIB (RFC 2574), VACM-MIB (RFC 2575 ) and RMON MIB 1, 2, 3, 9 groups (RFC 1757 and RFC 2819) Broadcast/Multicast/Unknown-Unicast Storm Control:In order to restrict broadcast/multicast/unicast-unknown communication in the network, broadcast/multicast storm control is being used. Limits can be set for each port. ACL (Access Control List): Like Firewalls, ACLs are safety regulations and standards in a network.These rules are stored, which participants may access on which ports and network. Access Control Lists Rules can be configured so that both incoming as well as outgoing traffic is controlled. Link Layer Discovery Protocol (LLDP): This is a manufacturer-independent protocol to enter into the network devices their identity, their skills and neighbors in an IEEE 802 LAN known. Upstream Power Back-Off (UPBO):Through the power back-off function, the signal level is reduced to the minimum absolutely necessary at different lengths, which leads to a better response to disturbances and lower power consumption. Downstream Power Back Off (DPBO): DPBO is a technology which prevents the crosstalk of the signal on other lines. This is especially necessary if the grid is being used by several operators. Without DPBO the DSL signal could interfere with the connections of other operators.
