Point-to-Multipoint Applications

In many instances, customers need to connect multiple remote sites to a central hub, and here
again, the EEI provides exceptional value and ease of use. With its multi-port interface and daisy
chain capability, your hub router doesn't need to know that there are multiple return paths. And
as your network grows, you won't need to change your network configuration or buy additional
router blades for your hub. Simply add the new hub demod to the end of your existing daisy
chain and you can bring a new remote online without any disruption to the existing traffic.
Figure F-3 illustrates how the DMD50, DMD20, and MD2401 multi demod can be utilized in the
same network to provide a large outbound carrier and various return carriers, typical of an
internet café application.
