Dial-Up Networking Troubleshooting
Problem: Dial-up networking disconnects in SmartGuard or in SmartSearch.
Solution: Sometimes dial-up networking disconnects because of the condition of the modem or telephone
lines. Close the DVR, access the Windows mode, and follow these instructions to test dial-up networking.
Go to My Network under Windows Explorer/Dial-Up Networking. Click the right mouse button and select
Properties.
Under the General tab, make sure the correct modem is selected under Connect using.
Under the Server Types tab, make sure that PPP: Internet, Windows NT Server, Windows 98 is selected under
Type of Dial-Up server box, and that the box next to TCP/IP is checked under Allowed network protocols.
Then, click OK if everything is correct.
Double click My Network to open the dialog box. Enter the telephone number for the POST system and
check if it is connected.
If the POST system is connected properly, try to access the remote site using SmartGuard or SmartSearch.
NOTE: Check the instructions again in Appendix 4 – Network Setup (Modem) if the POST system is not
connected.
Problem: The error message The line is busy has appeared even though the POST
system is not using the telephone.
Solution: Sometimes Windows refuses the remote connection even when the telephone line is not busy. Try
to connect again.
Problem: I cannot hear dial tone.
Solution: Sometimes the modem cannot access a dial tone if your telephone is an extension. Follow the
instructions below and then try to connect again.
Go to My Network under Windows Explorer/Dial-Up Networking, click the right mouse button and select
Properties.
Click General/Configure/Connection tab.
Uncheck the box next to Wait for dial tone before dialing.
Problem: The POST system does not answer a telephone call.
Solution: Under Windows Explorer/Dial-Up Networking, go to the pull-down menu Connection and then to
Dial-Up Server. Check Allow caller access.
Problem: After the POST system receives calls, the network disconnects.
Solution: Under Windows Explorer/Dial-Up Networking, go to the pull-down menu Connection and then to
Dial-Up Server. Click Server Types... and check if PPP: Internet, Windows NT Server, Windows 98 is selected
under Type of dial-Up Sever.
Problem: The POST system calls back the BASE system, however the connection fails.
Solution: Make sure that the dial-up networking is installed on the BASE system. If it is not installed, refer to the
Appendix 4 – Network Setup (Modem) for the instructions on setting up the dial-up networking. If the
connection fails although it is installed, make sure the IP address for dial-up connection of the BASE system is
"10.10.10.10".
