7400B Data Module

The following is an example:

atd74768 [ Enter ]

In the example, the command will cause the data module to go off hook, dial the number, and then wait the period of time specified in S-register S7 for the call to be completed.

If the call is not completed, the data module will disconnect and send the result code NO CARRIER to your display screen. When a call is successfully completed, the data module will send the result code CONNECT nnnn to your screen, where nnnn represents the speed of the 7400B Data Module, (for example, 1200).

REPEATING A COMMAND As mentioned earlier, the command buffer contains the last completed command line. If you wish to repeat the previous command line without retyping it, type A/ without the AT command prefix and without pressing [ Enter ].

This command is most useful when you have typed a command line to have the 7400B Data Module dial a number, and the data module returns the result code BUSY. Use the A/ command to redial the number as often as you wish.

STORING A TELEPHONE The 7400B Data Module is capable of storing up to four telephone

NUMBERnumbers, each of which can contain up to 25 characters. Numbers stored in this way remain available indefinitely, even after the data module has been powered off and then on again.

Table 4-3describes the command lines used to store a telephone number, delete a number from storage, and dial a stored number.

Note: Digits 0 through 9 and all letters “a” through “z” and “A” through “Z” may be part of the stored “number.” Spaces and hyphens (-) may be used in the number when typing the command line. Spaces are not stored and do not add to the total count of characters in the stored number, but all other ASCII characters are stored and counted. Any ASCII character may be used, as long as it is acceptable to the PBX.
