How can I access AT commands in leased line mode?


I have MT2834BR modems installed in a CC1600 modem rack. The problem is that in leased-line mode (DIP #10 DOWN) the modems do not respond to AT commands and no escape sequence (+++, etc.) is recognized. In dial-up mode AT command are accessible normally.


The modems don't normally respond to AT commands while in leased-line mode. If you want to change parameters, temporarily put the modem in dial-up mode (DIP #10 Up), give the modem your AT commands, store the parameters with the&W0 command. Now switch back to leased-line mode.
