Reference Guide for the Model RT328 and Model RH348 ISDN Routers

•Verify your IP address in Menu 3.2 and verify the following parameters in Menu 11:

–My Login

–My Password

–Rem IP Addr

If the call is connected but quickly terminated, it indicates the possibility of a negotiation problem.

•Check the error log in Menu 24.3.1, which usually provides some indication of why the call was dropped. If there is nothing in the log, the call may have been dropped by the remote device. Verify that the configuration parameters between these two devices are consistent.

If you are still unable to determine the problem, refer to Appendix D, “Using the Protocol

Analyzer and Trace Tools.”

Troubleshooting a Remote User Connection

To troubleshoot a remote user connection, follow these instructions:

•Verify that you configured the authentication parameters in Menu 13. These parameters are:

–CLID Authen

–Recv Authen

–Mutual Authen

•Verify that the IP address is supplied correctly in Menu 13 if the remote dial-in user is negotiating IP. Check that the remote dial-in user is supplying a valid IP address and that the router is assigning a valid address from the IP pool.

•Verify the user name and password for the remote dial-in user in Menu 14.

If you are still unable to determine the problem, refer to Appendix D, “Using the Protocol

Analyzer and Trace Tools.”
