Dialing an Unstored Telephone Number (n=phone number)
Lets you dial a telephone number of up to 50 characters without storing it in the modem's
telephone book.
To dial a number using AT commands, enter ATD, followed by the telephone number and a
carriage return. Example: ATD5551234<CR>
Dialing a Stored Telephone number (n=1-9)
Dial telephone number stored in address n. Before using this option, enter a telephone number
into the modem address book. See AT&Z, AT
If you enter ATDS or ATDS= without a number following, the modem dials the number in
Address 1.
To dial a number using AT Commands, enter ATDS, ATDS=, or AT
telephone book address number and a carriage return. For example: ATDS2<CR>
NOTE: You can include dial modifiers to instruct the modem how and when to dial a call. The
dial modifiers used with the AT ACU are described in Table A-4.
