2.5.6. VAS Card (DS-4ITX)
The VAS card (DS-4ITX) is developed to meet the growing demands of users for IN services.
Currently, it provides L2TP VPDN service, PPPoE Server Proxy service, network interface PPPoE
termination service, and VMAC service. It will provide the MPLS VPN service in the future.
Through software configuration, the VAS card can be loaded with different IN service FPGA logics to
support diversified IN services and flexibly meet the new market requirements.
The DS-4ITX module provides 4 100M fast Ethernet electrical interfaces. The physical interface is an
RJ-45 connector and the C5 twisted pair cable is used whose transmission distance is 100 m. The
cable length and peer interface type depend on the real situation.
