1.6.12DDR for Access Service

I.Networking requirements

We have designed the DDR implementation solution for access service by way of asynchronous serial port and ISDN PRI interface. Here, it is supposed that the dial string resources obtained by users from the telecom office are 8810048-8810055 and 8810148 respectively, serving 16 Internet users. In the configuration command, use Serial2:15 to identify ISDN PRI interface created at cE1/PRI interface.
