Configuring via the Terminal Port

To configure the T1 Modem Bank through the terminal port, follow these steps before starting up the T1 Modem Bank:

1.Make sure the T1 Modem Bank is shut off; then connect a terminal to the terminal port. Some terminals will not transmit data if their CTS (Clear To Send) line is LOW. These terminals must have their CTS line HIGH or floating to ensure that they will have no problems communicating with the T1 Modem Bank. Appendix C on page 91 shows a cable that can be used for these terminals.

2.Power up the terminal and set its communications parameters to 9600 baud, 8 data bits, no parity and 1 stop bit.

3.Power up the T1 Modem Bank and press ? on the terminal keyboard to bring up the configuration/diagnostic menu.

By pressing <Enter> at any time, you may exit the configuration/diagnostic mode without saving any of your changes. The POST will then resume if it had not been completed at the time you entered configuration/diagnostic mode. If POST had been completed when you entered configuration/diagnostic mode, the download will begin when you exit configuration/diagnostic mode.

To exit the configuration/diagnostic mode and save your changes, cycle the T1 Modem Bank’s power off, then on again to return to the initialized state.
