P, T Pulse or Tone Dialing

Default: T

The ISIHI-2S’s modems dials numbers by using pulse dialing, tone dialing, or a combination of both methods. Pulse dialing, used by rotary-dial telephones, uses the timed opening and closing of a relay to encode the numbers. Tone dialing, used by push- button (touch-tone) telephones, uses dual tone multifrequency (DTMF) dialing.

P selects pulse dialing.

T selects tone dialing.

Insert P or T in the dialing command just before the digits you want to pulse- or tone-dial. If neither pulse nor tone dialing is specified in the dial command, the modem uses whatever method was used last.

Note: When your modem is first turned on or reset, it uses the tone dialing method (which is the default), even if you do not include T in your dial command.

Examples:

To pulse-dial the number 555-1212, type ATDP5551212 and press ENTER.

To tone-dial the same number, type ATDT5551212 and press ENTER.

To call out of a PBX (switchboard) system where a 9 has to be pulse-dialed, and the rest of the number has to be tone-dialed after pausing for a second dial tone, type ATDP9,T5551212 and press ENTER. (The comma causes a pause.)

VSwitch to Speakerphone Mode

Inserting V into the dialing command causes the modem to switch to speakerphone mode and dial the following number. Use ATH to hang up.

WWait for New Dial Tone

Inserting W into the dialing command causes the modem to wait for another dial tone before it resumes dialing. (It is not necessary to enter W at the beginning of the dialing command.)

Note: Because the modem must be able to detect the dial tone for this command to work, you also must select wait-for-dial-tone dialing with the X2 or X4 command.

,Dialing Pause

Enter a comma in the dialing string to make the modem pause while dialing. This pause lasts two seconds (North American models) or four seconds (U.K. and International models) for each comma entered. You can force longer pauses by entering multiple commas, or you can change the length of the pause caused by a comma by setting register S8 to any value from 0 through 255 seconds (North American), 4 through 7 seconds (U.K.) or 4 through 255 seconds (International).

Note: Each comma in a dialing command counts as one of the 40 allowed characters.
