Provides the Gigabit Ethernet routing switch control card with network management for the end-to-end operation, network administration, maintenance, and provisioning of the MDU access concentration. The gigabit ethernet management control card can aggregate traffic from phone line cards to an external network device. The phone line ADSL2+ card can be operated either stand-alone or with the gigabit ethernet concentration or switching control board.

Fully Redundant MCU and Power Supply platforms designed for uptime reliability. A pair of redundant MCU and power supply are special designed for the VersaXpress-2000HD ADSL2+ IP DSLAM device without service interruption, and it also enables operation directly from AC power sources (or optional –48VDC power source). The wide AC voltage operating range supports worldwide operation.

Share the existing POTS (Plain Old Telephone Service) wiring to provide connectivity to subscribers, eliminating the need for new wiring. The system provides flexible and variety bandwidth services depend on the subscriber demand. This solution brings faster ADSL2+ high-speed networking Internet services to the subscribers by using existing phone-line found in the home and business.

With high bandwidth ADSL2+ technology, the voice and data operates simultaneously over the same pair of copper wire without interfering with voice service. The Concentrator can be remotely managed and software upgraded. This function eliminates the need for field upgrade. All cards are hot swappable which minimize service outage times. Four devices can be fitted into a standard Telco cabinet, up to 8 cabinet per a DSLAM group and total up to 27648 subscribers per system.

Provides most advanced 802.1Q tunneling (double VLAN Tagging) technology. By using this feature, service providers can use a single VLAN to support customers who have multiple VLANs. Customer VLAN IDs are preserved and traffic from different customers is segregated within the service-provider infrastructure even when they appear to be on the same VLAN. The 802.1Q tunneling expands VLAN space by using a VLAN-in-VLAN hierarchy and tagging the tagged packets. A port configured to support 802.1Q tunneling is called a tunnel port. When you configure tunneling, you assign a tunnel port to a VLAN that is dedicated to tunneling. Each customer requires a separate VLAN, but that VLAN supports all of the
customer's VLANs.
