Zyxel VES1724-55C
24-port Temperature-Hardened VDSL2 BOX DSLAM

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

The VES1724 Series conforms to G.993.2, G994.1 and G.997.1 to ensure the interoperability with standard-compliant VDSL CPE.

Ultra high-speed transmission with 30a profile support

The VES1724 Series supports 30a profile with 100 Mbps in both upstream and downstream traffics. With two Gigabit combo ports to connect upper layer aggregation networks, the VES1724 Series can support low-concentration interconnection from the subscriber ports to the network interface ports.

* 17a profile only when vectoring enable. ** 1. VES1724-55C and VES1724-58V support 17a profile.
2. VES1724-56B2 supports 30a profile.

Temperature-harden and friendly remote-installation design

The Zyxel VES1724 Series can operate in the environment with temperature from -40°C to 65°C, which meets various Fiber-to-the-Node and Fiber-to-the-Curb environment conditions worldwide. Moreover, for the VES1724-58V, the rotational speed of the fan module is automatically adjusted according to the system temperature. With the fanless design for the VES1724-55C/56B2, the feature not only extends the MTBF, but also has lower audible noise, which is important if the VES1724 Series is installed in a residential neighborhood. The fan module is swappable in order to reduce the maintenance cost in the field.

Triple-play ready

The VES1724 Series 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 Series 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 Series allows the operators to provide triple-play services over the same copper wire.

SIP and H.248 for smooth voice over IP migration (VES1724-58V)

The Zyxel VES1724-58V has SIP and H.248 enabled, with which analog voice signals coming from subscriber lines can be digitalized and transmitted to the SIP or H.248 voice core. The capability enables operators to turn traditional voice exchange into VoIP core without any impact on the subscriber side. It also makes the migration pace to the entire VoIP infrastructure controllable.

AC/DC power with battery charger to facilitate field installations

The Zyxel VES1724 Series is a temperature-hardened remote system with dual power supply that can be powered by either AC or DC sources. The operator staff can easily power the mini MSAN and put it in service based on the power facility type at the installation site. Furthermore, because the VES1724-58V embedded battery charger function, customer doesn’t need an additional SMR for powering the VES1724-58V and charging backup at the same time. It will reduce CAPEX and the effort for installation.
