Table 2-15 continued Problem Phone line noise is causing a disconnection. No dial tone Possible Cause Solution Hang-up Delay S Register (S10) is set too low. Phone service is not connected to the telephone wall jack. Change S10 default to 150. To set S10=150: 1. Select Start ! Programs ! Accessories ! HyperTerminal, then go to Command Mode. 2. Type ATS10=150 and press Enter. This command causes the modem to take longer to disconnect even if there is noise on the line. Verify that service from the local phone company exists by following these steps: 1. Unplug the telephone cable from the telephone wall jack. 2. Connect a telephone to the jack, pick up the handset, and listen for a dial tone. If there is a dial tone, reconnect the modem to the telephone wall jack with the telephone cable and make sure all connections are secure. 3. If there is still no dial tone, contact your local phone company or building manager. Continued 2-30 Troubleshooting
