DDR Configuration

1.3 Preparing DDR Configuration

For a network needing DDR, subscribers can make configuration preparations following the flow below.

zSpecify which routers in the network need DDR, which interfaces of these routers use DDR, what transmission medium is used, what topology is adopted, whether these interfaces are sending calls, receiving calls, or sending and receiving calls at the same time.

zSpecify the type of interface to be used (asynchronous serial port or ISDN BRI/PRI interface).

zSpecify the interface encapsulation to be used (PPP etc.).

zSpecify the network protocol to be used (IP or IPX etc.).

zSpecify the dynamic routing protocol (RIP etc.) to be used at DDR interface.

zSelect either Legacy DDR or Dialer Profile to configure DDR.

zConfigure DDR.

The flow chart of configuration preparations is shown in the following figure.
