How to troubleshoot network

1. Stop YDC application

2. Startupàrun

3. Type “cmd” and go to command line console

4. Check the current IP setting by typing “ipconfig”

5. Ping itself by typing “ping xxx.xxx.xxx.xxx.”, in the string “xxx.xxx.xxx.xxx” is the ATM IP address

6. If ping itself timeout, you should check network interface card and TCP/IP protocol installation

7. If ping itself working, ping gateway

8. If ping gateway timeout, you should check the physical cable and middle network device like hub from ATM to gateway, also you should check the gateway

9. If ping gateway working, ping switching system

10. If ping switching system timeout, you should check the physical cable and middle network device like hub from gateway to switching system, also you should check the switching system

11. If ping switching system working, you should check if the port of the switching system is ready for ATM, by typing “telnet xxx.xxx.xxx.xxx pppp”, in the string “xxx.xxx.xxx.xxx” is the IP address of switching system, “pppp” is the port number for ATM service.

12. If telnet failed, responding “can not open pppp port on xxx.xxx.xxx.xxx”, that means the switching system is not ready

13. If telnet success, you can see the response data came from switching system on telnet terminal window, that means no problem with network.

14. If no problem with network, but the ATM stay offline, you should check the YDC network setting by running application YDCConfiguration. Check the network header type, check the IP and port setting .
