Nortel Networks NN46110-602 manual Action

170 Appendix B Using serial PPP

Cause:

You were dialed in and managing the VPN Router remotely using PPP and you changed the baud rate and applied it, but now you cannot manage the VPN Router.

Action:

To manage the VPN Router, disconnect the dial-up connection and try to re-establish it. This gives the modem a chance to renegotiate the baud rate with the VPN Router.

Cause:

You are set up to use PPP but want to use the serial port for the serial menu.

Action:

Choose the serial port mode Serial Menu. Press OK using the Web management interface (System > System Settings) and restart the VPN Router. To use the Serial Menu, you must install a serial cable in place of the modem. Remember to power off the VPN Router when plugging in and unplugging the serial port connection; otherwise, you can damage system components.

Cause:

You are set up to use the Serial Menu but want to use the port for PPP.

Action:

You can change the serial port settings (System > System Settings) or the Serial Menu itself. For these changes to take effect, restart the VPN Router. For the best results, connect the modem while the VPN Router is turned off.

Cause:

You are using a dial-up serial PPP connection and you encounter repeated CRC errors.
