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.

1.1.1.26Structure of the DS-4ITX module

The front panel of the DS-4ITX module is shown in the following figure:

The front panel of the DS-4ITX module is composed of the following parts:

„4 RJ-45 10/100M Ethernet electrical interfaces

„4 ACT indicators

„4 LINK indicators

Of the above, the different states of LINK and ACT indicators show the port operating status. For details, refer to Table 2-19.
