Section 11: Dial-Up Remotes Can't Dial Out

1. The most reliable tool for troubleshooting a dial-up connection is a plain old phone. (Note: You need two techs for this: one at the NOC and the other at the remote site.) Have the remote site tech dial into the master with an ordinary telephone and listen:
2. Does it ring? If it doesn't, check your phone line.
3. Does the master pick up?
4. Do you hear the modem? Or do you hear a "This call cannot be completed" message?

What's going on: Remote sites often aren't allowed to call long-distance. If the remote site and the NOC are in different area codes, you may not be able to connect.

5. If the phone line is OK, try dialing into the master using a PC running HyperTerminal. The master will try to resolve the HyperTerminal connection as if it were the remote dialing in to report an alarm.
6. Watch the HyperTerminal window. Check if you get a connect message. Check if you're connecting at the correct baud rate.
7. If you still can't connect, troubleshoot the master's modem.
