3ODQQLQJ+',$'DWDDQG9RLFH6XEQHWVHigh Density Internet Access (HDIA) uses an encapsulationtype of IP-1490 on its DSL voice VCs and an encapsulation typeof RFC-1483 on its DSL data VCs.Multiple voice groups and multiple data groups are permissible.Different voice gateways located at different places can servedifferent voice groups; different ISPs or enterprise routers locatedat different places can serve different data groups.In the following example, the focus is on IADs whose voice VCsbelong to a single voice group and whose data VCs belong to asingle data group. The data VCs on the DSL links have addresseson the same subnet as their router. The voice VCs have addresseson the same subnet as their voice gateway.HDIA Data Group (10.0.20.0)4Hosts1HostIADIADHDIADSLAMDefaultRouterHDIA Voice Group (10.0.21.0)8Phones8PhonesIADIADHDIADSLAMVoiceGatewayHDIA Netmodel—Data and Voice GroupsTo plan the addressing for an HDIA data or voice group on theCE150, follow these steps:1. DSLAM and IADs:a) Create two diagrams.Each has a DSLAM in the middle and multiple IADson the left side connected by lines to the DSLAM.b) Label the first diagram, HDIA-Data.c) Label the second diagram, HDIA-Voice.2. DSLAM, Router, and Voice Gateway:a) On the first diagram, draw a default router,connected to the right side of the DSLAM.b) On the second diagram, draw a voice gatewayconnected to the right side of the DSLAM.&KDSWHU9RLFHRYHU'6/
