Dial Modifier Commands - Multitech MT5634HD16 User Manual

MT5634HD8/16 User Guide
Hn On-Hook/Off-Hook
n = 0 or 1
Default: 0
Use the H command to make the modem hang up (go on-hook) or simulate the action of picking up a
telephone handset (go off-hook).
H0 (or H) hangs up the modem
H1 brings the line off-hook, just as if you had picked up the telephone handset.
It is not necessary to use the H1 command to bring the line off-hook when using the D command. The
modem automatically goes off-hook when you press E

Dial Modifier Commands

The dial string can include the digits 0 through 9 , the pound sign ( # ), the asterisk ( * ), and the letters A , B ,
C , or D . The latter are used by some PBXs; the exact function will depend on the PBX manufacturer's
feature set and implementation. There are also several command characters, called "dial modifiers," that
can be included within a dialing command after the letter D . Their functions include pulse or tone dialing,
pauses in the dial sequence, automatic redials if a number is busy, and reverting to command mode or
switching to answer mode after dialing.
L Redial Last Number
Default: none
You can redial the last number dialed by entering L immediately following the dial command (ATD). This
command is handy if you encounter a busy signal and want to try the call again.
P, T Pulse or Tone Dialing
Default: T
The MT5634HD8/16's modems can dial 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.
16
at the end of the dial command.
