Some of you may have heard of devices called Remobs which stands for Remote 
Observation System. These Devices allow supposedly authorized telephone 
employees to dial into them from anywhere, and then using an ordinary touch tone 
fone, tap into a customer's line in a special receive only mode. [The mouthpiece 
circuit is deactivated, allowing totally silent observation from any fone in the 
world (Wire tapping without a court order is against the law)] 

[__How 
Remobs Work______________] 
Dial the number of a Remob unit. Bell is rumored 
to put them in the 555 information exchanges, oron special access trunks 
[Unreachable except via blue box]. A tone will then be heard for approximately 2 
seconds and then silence. You must key in (In DTMF) a 2 to 5 digit access code 
while holding each digit down at least 1 second. If the code is not entered 
within 5 or 6 seconds, the Remob will release and must be dialed again. If the 
code is supposedly another tone will be heard. A seven digit subscriber fone 
number can then be entered [The Remob can only handle certain 'exchanges' which 
are prewired, so usually one machine cannot monitor an entire NPA]. The Remob 
will then connect to the subscribers line. The listener will hear the low level 
idle tone as long as the monitored party is on hook. As the monitored party 
dials [rotary or DTMF], the listener would hear [And Record] the number being 
dialed. Then the ENTIRE conversation, datalink, whatever is taking place, all 
without detection. There is no current box which can detect Remob observation, 
since it is being done with the telephone equipment that makes the connection. 
When the listener is finished monitoring of that particular customer, he keys 
the last digit of the access code to disconnects him from the monitored line and 
return to the tone so that he can key in another 7 digit fone #. When the 
listener is totally finished with the Remob, he keys a single 'disconnect digit' 
which disconnects him from the Remob so that the device can reset and be ready 
for another caller. 

[_History of Remobs_______________] 
Bell has 
kept the existance of Remobs very low key. Only in 1974, Bell acknowledged that 
Remobs existed. The device was first made public during hearings on "Telephone 
Monitoring Practices by Federal Agencies" before a subcommittee on government 
operations. House of Representatives, Ninety-Third Congress, June 1974. 


It has since been stated by Bell that the Remob devices are used 
exclusively for monitoring Bell employees such as operators, information 
operators, etc., to keep tabs on their performance. [Suuureee, were stupid] 


[__Possible Uses for Remobs__] 
The possible uses of Remobs are 
almost as endless as the uses of self created fone line. Imagine the ability to 
monitor bank lines etc, just off the top of my head I can think of these 
applications: 

Data Monitoring of: 
TRW 
National Credit Bureau 

AT&T Cosmos 
Bank Institutions 
Compuserve and other Networks. 


Voice Monitoring of: 
Bank Institutions 
Mail Order buisnesses. 

Bell Telephone themselves. 
Any place handling sensitive or important 
information. 
Anyone that you may not like. 

With just one Remob, 
someone could get hundreds of credit cards, find out who was on vacation, get 
compuserve passwords by the dozens, disconnect peoples fones, do credit checks, 
find out about anything that they may want to find out about. Im sure you 
brilliant can see the value of a telephone hobbiest and a telecommunications 
enthusist getting his hands on a few choice Remobs. 


[_Caution________________________] 
If any reader should 
discover a Remob during his (or her) scanning excursions, please keep in mind 
the very strict federal laws regarding wiretapping and unauthorized use of 
private Bell property.
