* Introduction:
|
|
|
|
Since the days of hacking using a standard telephone line are almost over,
|
|
many of todays hacker community are moving towards cellular communications.
|
|
|
|
ESN/MIN pairs are no longer difficult to obtain and if used carefully will
|
|
last much longer than calling cards, codes and most other methods of phone
|
|
phreaking.
|
|
|
|
This text file will explain how to easily connect any cellular phone to a
|
|
modem, without the expense of buying a cellular line interface or
|
|
similar device.
|
|
|
|
* What you will require:
|
|
|
|
To undertake this project you will require the following;
|
|
|
|
1 desktop telephone
|
|
1 telephone doubler socket
|
|
4 lengths of wire (30cm long)
|
|
1 roll of solder
|
|
1 roll of masking tape
|
|
|
|
You will also require a soldering iron, wire strippers and a screw driver.
|
|
|
|
* Instructions:
|
|
|
|
1. Unscrew the screws holding your desktop telephone handset together. Remove
|
|
the ear piece speaker and microphone from the plastic moulding and cut
|
|
the wires connected to them.
|
|
|
|
2. Now solder the 30cm long lengths of wire onto the existing handset ear
|
|
piece speaker and microphone wires. Once you have done this, simply re-solder
|
|
the ear piece speaker and microphone onto the extended handset wiring.
|
|
|
|
3. Place the extended handset ear piece speaker over the mouth piece on your
|
|
cellular telephone and wrap in masking tape. This will not only hold the
|
|
extended handset ear piece speaker in position, but also prevent background
|
|
noise problems.
|
|
|
|
4. Now place the extended handset microphone over the ear piece on your
|
|
cellular telephone and wrap in masking tape as above.
|
|
|
|
* How to use the device:
|
|
|
|
Basically, what you have done is turned your desktop telephone into an
|
|
accoustic coupler type device. To use the device, simply follow the
|
|
instructions below.
|
|
|
|
1. Plug your telephone doubler socket into your telephone socket. Plug
|
|
your desktop telephone into one socket and your modem line into the other
|
|
socket.
|
|
|
|
2. Leave your telephone handset off the hook until your line is completely
|
|
dead. (i.e. after you have listened to "please replace the handset and try
|
|
again" or something similar about 10 times.
|
|
|
|
3. Dial the modem dialup you wish to call on your cellular phone and
|
|
press SEND as you would normally.
|
|
|
|
4. Type ATD into your terminal package and press return. Your modem should
|
|
now be off the hook and waiting for a carrier signal from your cellular
|
|
telephone.

|

|
* How it works:
|
|
|
|
The carrier signal from the remote modem will be sent out of your cellular
|
|
telephone ear piece speaker and into the desktop telephone handset
|
|
microphone. Your modem will receive any data send into the desktop telephone
|
|
handset after the ATD (off-hook) command has been issued.
|
|
|
|
In the same way, any carrier signals from your modem will be sent out of the
|
|
desktop telephone handset earpiece speaker and into your cellular telephone
|
|
microphone.
|
|
|
|
At the time of writing, I have not connected at speeds higher than 1200 baud
|
|
due to the low quality of anologue cellular network telephone lines. I would
|
|
expect that those using transportable cellular phones (such as the Motorola
|
|
4800 and 6800 series) should have no problems connecting at 2400 baud or
|
|
higher.
|
|
|
|
I did not write this text file so that people could use it to transfer large
|
|
amounts of data at high speed. This is simply a guide to explain how easy
|
|
it is to use any cellular telephone with a modem. 1200 baud may be slow,
|
|
but it is fine for hacking, calling your favourite underground BBS or
|
|
transfering text files --- especially if you are not paying for it!
