VDSM2-1524 1.5U 24-port VDSL2 IP DSLAM

VDSM2-1524 1.5U 24-port VDSL2 IP DSLAM

The VDSM2-1524 is a 24-port VDSL2 IP DSLAM with 2 Gigabit Ethernet Combo interfaces built-in, achieved in 1.5U height design. The VDSM2-1524 offers the fastest data rate over the existing copper infrastructure. In order to connect with the growing Carrier Ethernet applications, the VDSM2-1524 provides the ideal solution in the last mile. The VDSM2-1524 is able to provide a faster data transmission easily with the latest VDSL2 technology in order to handle the rapidly growing demands of triple-play media. The VDSM2-1524 supports switch management functions, such as, port speed configuration, port link aggregation, IEEE 802.1Q VLAN, Q-in-Q VLAN, and ACL security. In addition, it features advanced functions, such as IGMP snooping, QoS, bandwidth control etc. The VDSM2-1524 allows its users to provide a better secured network service with enforcing security policies, such as MAC filter, Static MAC, IP/MAC binding and port security.
