24-port Temperature-Hardened VDSL2 Box DSLAM

Compact and Full-featured VDSL2 Technology

Compliant with ITU-T G.993.2, G994.1, G.997.1, G.998.4 G.inp, and G.993.5 vectoring

The VES1724-55C conforms to G.993.2, G994.1 G.997.1, G.998.4 G.inp, and G.993.5 vectoring to ensure the interoperability with standard-compliant VDSL CPE.

Ultra high-speed transmission with 17a profile support

The VES1724-55C supports 17a profile with 100 Mbps in downstream traffics. With two Gigabit combo ports to connect upper layer aggregation networks, the VES1724-55C can support low-oncentration interconnection from the subscriber ports to the network interface ports.

Triple Play ready

The VES1724-55C supports IGMP snooping to prevent unnecessary forwarding of multicast traffic to all subscribers and thus optimizes bandwidth utilization for multicast applications such as broadcast video.The VES1724-55C also supports the multicast VLAN feature that distributes the source to all the VLANs requesting the video stream. With a built-in splitter over POTS, the VES1724-55C allows the operators to provide Triple Play services over the same copper wire.

Complete QoS for service differentiation

The VES1724-55C supports not only 802.1X port-based access control for subscriber authentication, but also defines a limited number of MAC addresses that can access the network from a particular port. With rate limiting on the subscriber ports allowing services to take advantage of 64 Kbps increments, service providers will be in a better position to offer tiered services.
