TR Troubleshooting - Modem Problems 

Are you having a problem accessing or using a modem connected to the ring as a shared modem? 
Go to page 11.1. 

Are you having a problem accessing or using a modem connected to a specific ring station or file server as an unshared modem? 
Go to page 11.2. 

Are you having a problem accessing or using a modem connected to a ring from a remote location?
Go to page 11.3. 

If the respective modem is connected to a ring station or a file server, it is not actually considered a network peripheral because it does not contain its own NIC. In this case, the procedures beginning on this page are applicable. If the modem does contain its own NIC, you should troubleshoot the problem as a network peripheral by going to page 10. If after troubleshooting the problem as a network peripheral you feel that the modem or modem-sharing software is at fault, come back to this page. 

This procedure is generic as to the modem and modem network-sharing software manufacturer. For some of the troubleshooting steps on this page, you should also reference the manufacturer's documentation for any special 



11.1 You have a problem accessing or using a modem connected to the ring as a shared modem.

Check the ring station or file server to which the modem is connected and the modem itself to make sure that they are configured with all the proper hardware and software components and the correct configuration parameters. Also check the network file server for all the correct modem-sharing software and proper configuration.

Are any incorrect configuration parameters present in either the respective ring station, modem, or network file server?

Take the necessary action to resolve the problem, and retest the modem for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step .

Attempt to run any available modem diagnostics and troubleshoot the modem link cables and phone lines.

Did running the diagnostics, checking the link, or checking the phone lines produce any errors?

Take the necessary action to resolve the problem and retest the modem for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step .

A configuration problem may still exist with the modem or the modem network-sharing software. Reference the respective modem and modem-software manufacturers' instructions.

A configuration problem may still exist with the modem. Reference the respective modem manufacturer's instructions.



11.3 You have a problem accessing or using a modem connected to a ring from a remote location.

Check the local and host ring stations to which the modems are connected and the modems themselves to make sure that they are configured with all the proper hardware and software components and the correct configuration parameters. Also check the host network file server for all the correct modem-sharing software and proper configuration.

Are any incorrect configuration parameters present in either the respective ring stations, modems, or host network file server?

Take the necessary action to resolve the problem and retest the modems for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step .

Attempt to run any available modem diagnostics and troubleshoot the host and remote modems, link cables, and phone lines.

Did running the diagnostics, checking the link cables, or checking the phone lines produce any errors?

Take the necessary action to resolve the problem and retest the modems for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step .

A configuration problem may still exist with the modems or the modem network-sharing software. Reference the respective modem and modem-software manufacturers' instructions.
