When using AT commands, the following criteria must
be met:
• Make sure the asynchronous DTE’s communication
software is configured for 10-bit character format
(for example, 8 data bits, no parity, and 1 stop bit).
• Make sure the DTE (RS-232D) cable is attached to
the DTE connector at the rear of the COMSPHERE
3000 Series Carrier, and to the correct serial
communications port on the asynchronous DTE.
• On initial power-up, the modem is in Command
mode. To verify that the modem is connected and
functioning properly, enter the following:
TYPE: AT
PRESS: Return (Enter)
The screen displays OK.
If the modem does not return OK, refer to Appendix C,
Troubleshooting.

factory preset configuration you
may have lost AT command
control. To regain AT command
