	Juno Support - Connecting - Pulse dialing not working- Free Dial Up Internet Service - High Speed ISP - Net Zero ...
		If you are not able to get Pulse dialing working in Juno, first, make sure your dialing options in Juno are set correctly for your particular telephone setup.
		If your dialing options are set correctly, the problem may be occurring because your modem can only dial "tone" or because your telephone line only supports tone dialing.
		If the modem dials using tone rather than pulse, the problem is most likely with your modem's dialing capabilities rather than with how Juno is telling your modem to dial.In this case, please contact your modem manufacturer or consult your modem's manual for more information.

	Pulse dialing - Wikipedia, the free encyclopedia
		Pulse dialing or loop disconnect dialing, also called Rotary or Decadic dialing in the United Kingdom (because up to 10 pulses are sent), is pulsing in which a direct-current pulse train is produced by interrupting a steady signal according to a fixed or formatted code for each digit and at a standard pulse repetition rate.
		As a result, all that is really needed to dial a number with pulse dialing is a switch (i.e., the telephone receiver hook-switch).
		Most fixed-line phones now use dual tone multi frequency (also called touch tone or tone dialing) rather than pulse dialing, but most telephone equipment retains support for pulse dialing for backward compatibility.

		Pulse dialing is traditionally accomplished with a rotary dial, which is a speed governed wheel with a cam that opens and closes a switch in series with your phone and the line.
		This is the pulse measured at the telephone, not at the exchange, where it's somewhat different, having traveled through the phone line with its distributed resistance, capacitance, and inductance.
		Pulse dialing is to touch-tone as FSK or AFSK RTTY is to Switched Carrier RTTY, where mark and space are sent by the presence or absence of DC or unmodulated RF carrier.

	History/Tech pg 1 (Site not responding. Last check: 2007-10-22)
		Normal telephone dialing originally used pulse, which is simply a series of electrical interruptions; each click rapidly breaks and reconnects a the local loop (a circuit formed between the ring and tip wires of the telephone, and the telco equipment in the local company office).
		Pulse was designed to move relays a certain distance, based on the number of voltage pulses received by the equipment.
		This is one way to bypass a dialing lock, which is intended to prevent anyone from making outgoing calls from a particular phone (often used in offices or other places where many people have access to the telephone).

		The rotary dial is a device mounted on or in a telephone or switchboard that is designed to send interrupted electrical pulses, known as pulse dialing, corresponding to the number dialed.
		To dial a 6, the user puts a finger in the 6 fingerhole and rotate the dial clockwise until it reaches the fingerstop.
		For this reason, the numbers on the dial are shifted in different countries to work with their system because of the difference of the number arrangement on the dial.

		Also known as rotary dialing, this dial modifier follows the D command and precedes the telephone number to tell the modem to dial the number using pulse service.
		If you need to dial a number that is too long to be contained in the command buffer (45 characters for the D command), use the (;) modifier to separate the dial string into multiple dial commands.
		The W dial modifier causes a modem to wait for an additional dial tone before dialing the numbers that follow the W. The length of time the modem waits depends on the value in S-Register S7.

		The pulse results from pressure waves moving through the blood vessels, which are pliable; it is not caused by the forward movement of the blood.
		The pulse deficit (difference between heart beats and pulsations at the periphery) should be determined by simultaneous palpation at the radial artery and auscultation at the heart apex.
		Pulse is a measure of the heart rate, however it also has other properties which are characteristically changed in some diseases: rhythm, fullness and the shape of the pulse wave.

	Telemetry device including a dynamic off-hook detector capable of operationg in a pulse-dialing environment - Patent ...
		If, during the on-hook portion of the dial pulse, an indication is received that a contending device has gone off-hook, then the dynamic off hook detector of the telemetry device disengages the phone line and returns the telemetry device to the static state.
		The "pulse dialing" or rotary pulse format is based upon the mechanical rotation of the old-style telephone dial which interrupts the loop current in a prescribed manner.
		Recalling that pulse dialing involves the MIU going on-hook and off-hook to pulse the loop current, the dynamic off-hook detector, which normally functions by sensing the current shunted away from the active MIU, has no current to measure while the MIU is in the on-hook portion of the dial pulse.

	Pulse dialing
		Pulse dialing, also called Decadic dialling in UK, (because up to 10 pulses are sent), is Pulsing in which a direct-current pulse train[?] is produced by interrupting a steady signal according to a fixed or formatted code for each digit and at a standard pulse repetition rate.
		Because the pulses are generated through the making and breaking of the telephone connection (akin to flicking a light switch on and off), all that is really needed to dial a number with pulse dialing is a switch (ie.
		Modern phones increasingly use dual tone multi frequency (touch tone) rather than pulse dialing.

		In both cases the modem will not dial as it is configured to identify the absence of dial tone and the presence of a busy tone.
		Some hotels use "pulse" phone systems internally but outside call are dialed in "tone" - to get a line it is necessary to dial the access number in "pulse" - configure the modem for pulse dialing.

		In theory, you should be able to dial by whisteling or singing but in practice that turns out to be impossible since the frequency pairs that make up touch tone numbers are such that they cannot be generated by a single resonating body.
		When using pulse dialing, each digit dialed is converted into a series of "pulses", where the number of pulses correspond to the number dialed.
		Pulse dialing is being phased out in most parts of the world and is being replaced by tone dialing.

	Mixing Tone and Pulse Dialing in Cardfile and Terminal (92900) (Site not responding. Last check: 2007-10-22)
		Some phone systems are restricted to pulse dialing until an outside line or other phone service is reached by dialing a prefix, such as "9." Because tone dialing is faster than pulse dialing, you may want to dial the prefix in pulse and then switch to tone dialing for the actual phone number.
		To pulse dial a prefix and then tone dial the phone number, select the Pulse option as the default.
		Note: A modem that is set for tone dialing can be switched to pulse dialing by inserting a "P" instead of a "T." In Cardfile, the "P" or "T" can also be inserted in the phone number, rather than the prefix.

		DTMF was developed at Bell Labs in order to allow dialing signals to dial long-distance numbers, potentially over non-wire links such as microwave links or satellites.
		It was clear even in the late 1950s when DTMF was being developed that the future of switching lay in electronic switches, as opposed to the mechanical crossbar systems currently in use.
		In this case pulse dialing made no sense at any point in the circuit, and plans were made to roll DTMF out to end users as soon as possible.
