Autodialers are a excellent way to allow "Least Cost Routing" of various international calls through different long distance carriers, but they are especially useful for companies that are using international callback, or any service where a access # is dialed and then a authorization code is entered, followed by a desired called #.

Below you will find the introduction to the GSAutodialer.  For multiple orders, a Sample and operation instruction can be sent to you upon request. We believe you will find it's powerful, flexible, and easy to use.

GS auto-dialer is a programmable call routing device specially designed for eliminating dialing procedure and routing calls through alternative carriers.

1. Features:

• GS auto-dialer is about the same size as mouse, use international-standard joint, it's exquisite and easy to install and use.
• GS auto-dialer is microprocessor-based and is programmable.
• GS auto-dialer is supported by an easy to use, PC based programming system.It is a Windows based program, it runs on Microsoft Windows 3.X or Windows 95. The user does not need to know a programming language.
• GS auto-dialer dialing operation is transparent to the user.
• GS auto-dialer can be programmed locally (at site) or remotely over the telephone line. Programming is security code protected.
• All programmed data are stored in non-volatile memory.
• GS Auto Dialer is the only dialer that can use 2 AAA size batteries without any transformer. It's more convenient and easier to install for common consumers.
• GS auto-dialer is programmed with Intercept Sequences. These are sequences of digits that tell GS auto-dialer it is time to do something such as dial a certain number or wait to detect dial tone, etc. It can also be programmed to execute certain  Exception Sequences. These are exceptions to the Intercept Sequences.

For example, if you wish to intercept international calls and route them through the alternative carriers, but international call to certain countries are to be dialed through the regular telephone network, those countries' country codes would be included in the Exception Sequences. If an exception number is dialed by the user, GS auto-dialer will allow that number to pass through to the regular telephone network rather than intercept and process the call through the alternative carriers. A wild card feature allows various kinds of numbers to entered as exceptions.

• GS auto-dialer may be programmed to re-route a call through the regular telephone company's network or another alternative carriers's network upon detection of a certain fourth column DTMF tone(A, B, C or D) generated by the initial alternative carriers.

In order to use an alternative carriers rather than the regular telephone company to make long distance calls, you must dial a number to access the alternative carriers' system, wait for the system to respond, dial in DTMF tone a password or PIN (Personal Identification Number), and dial in DTMF tone the number you wish to reach.

For example, say you are in H.K., and the number to access the alternative carriers' system is a local number, 12345678, and you have been assigned the PIN 98765, and you want to call someone in US at the number 4084672111. To make an international call using the alternative carriers, you dial 12345678, wait for the system to answer, wait for the system to prompt you for your PIN 98765 followed by the # sign, dial the destination number 0014084672111(00 means an international phone call), that's all. But most subscribers to the alternative carriers will find the above dialing procedure to cumbersome and may not want to go through the trouble every time. If you are the alternative carriers, to gain more customers you may want to be able to :

1. eliminate the cumbersome dialing procedure altogether.
2. capture every long distance call dialed by the subscriber.
3. avoid having to carry calls meant for destinations for which it (the alternative carriers) cannot offer savings.

GS auto-dialer can solve all of the above problems.

When you have an GS auto-dialer, that has been properly programmed to service a particular subscriber, installed on the subscriber's telephone line and connected to the telephone that he/she uses to dial. There's no need to instruct the subscriber to follow any special dialing procedure when making a long distance call. He/she simply dials the long distance call in exactly the same manner as he/she would normally do when dialing the long distance call throughout the regular telephone network of the telephone company.

All the dialing procedure described above that subscriber needed to follow to make a long distance call through the alternative carriers (without the use of GS auto-dialer) will be automatically performed by the GS auto-dialer in a manner that is transparent to the subscriber. In other words, the subscriber is unaware of dialing operation carried out by the GS auto-dialer. GS auto-dialer is, in fact, a little robot that emulates all the dialing action that other wise have to be performed by the subscriber to make a long distance call through the alternative carriers.

The operation of the GS auto-dialer is such that it is always ready to read the digits of all the telephone numbers dialed by the subscriber. Ordinarily, it allows all non-long distance calls to be dialed through the regular network of the telephone company, but once it detects that a long distance call (one that the alternative carriers wants to carry) is dialed by reading the first few digits of the telephone number dialed for the dialing code for long distance call or international call, it will intercept the call and perform two sets of actions concurrently.

In the case of example for the call to US, the subscriber in H.K. dials the number 0014084672111, and the GS auto-dialer will intercept the call as soon as it sees it- or reads the digits -001- and perform the following two sets of actions concurrently.

First set: It continues to collect and store all the digits dialed by the subscriber and when it has finished collecting all the digits dialed it remains off-hook with respect to the subscriber(the person doing the dialing).

Second set: It goes on-hook with respect to the CO (Central Office, i.e., the telephone exchange) for a predetermined (by programming) duration of 1 second or more and then goes off-hook and waits to detect dial tone and then dials the access number 12345678 that has been programmed in it. It waits for the prompt from the alternative carriers' system to enter the PIN followed by the # sign and tone dials 98765#. Upon detecting the next prompt for the destination number followed by the # sign, it dials tone 0014084672111, the number that the person had dialed and it had collected.

• GS auto-dialer may be programmed to enable the user of PBX to get the PSTN (Public Switched Telephone Network) directly.

Usually, the user of PBX have to dial the digit -9 -or  -0 - to get connection with the PSTN through the PBX. With the use of GS auto-dialer, you can omit this procedure, just dial the destination number only. The auto-dialer will distinguish it's for another extension or for outside connection automatically (even if the first few digits of the destination number is the same as a extension number), then it will connect the extension or the destination. In this way, for the user, a telephone extension of PBX can be used exactly the same as a directly-connected (with the PSTN) telephony device, and it still have the advantage of PBX.

l CO (Central Office): telephone company facility where subscribers+IBk- lines are joined to the switching equipment for connecting other subscribers to each other, locally and long distances. Some times CO has the same meaning as -telephone exchange - or  public exchange. Sometimes CO means a wire center in which there might be several switching exchanges.

l DTMF: Dual Tone Multi Frequency, a fancy describing push button or touchtone dialing. In DTMF, when you press a button on a touchtone pad of a telephone, it makes a tone, actually the combination of two tones, one high frequency and one low frequency, thus the name Dual Tone Multi Frequency.

l Off-hook: when the telephone handset is lifted off its cradle. When the handset is removed from its cradle, it completes the electrical loop, thus signaling the CO that it wishes dial tone.

l On-hook: when the telephone handset is resting in its cradle. The telephone is not connected to any particular line. Only the bell is active, i.e., it will ring if a call comes in.

l PSTN: Public Switched Telephone Network, usually refers to the worldwide voice telephone network accessible to all those with telephones and access privileges.
