REMOBS
|
||
|
||
The Silver Box, as stated earlier, is a lineman's handset or REMOBS
|
||
(Remote Service Observing Systems). They allow Bell employees and phreakers
|
||
to use the system to tap phones. By using a Silver Box and an ordinary Touch-
|
||
Tone phone, one can dial directly into the RECEIVE ONLY portion of any
|
||
customer's line (the mouthpiece is disconnected). Silver Boxes work as
|
||
follows:
|
||
Dial the number of a REMOBS unit. Bell apparently puts them in the 555
|
||
information exchange (XXX-555-XXXX). A tone will then be heard for about
|
||
two seconds and then silence. It is then necessary to key in, with a Touch-
|
||
Tone, a 2-5 digit security code, holding each digit down at least one second.
|
||
If the code is not entered within 5-6 seconds, the REMOBS will disconnect,
|
||
and must be dialed again. If the code is properly entered then another tone
|
||
will be heard. Any 7-digit customer number can then be entered (the REMOBS
|
||
can only handle certain exchanges which are prewired for it, and usually one
|
||
machine can't monitor all of a multi-Central Office locality).
|
||
The REMOBS will then connect up to the customer line. The phreaker will
|
||
hear the low level idle tone. As the monitored party dials, the phreaker
|
||
will hear the number being dialed and the entire conversation! At no time
|
||
will the monitored party be aware that he has been tapped - there are no
|
||
messages, clicks, strange sounds, etc.! When the phreaker is done listening
|
||
to Customer A, he can key in a single "reset digit" (usually the last digit
|
||
in the access code), which disconnects him from the monitored line and
|
||
returns him to the tone so that he can dial Customer B. When the phreaker
|
||
wants to quit, he keys in a single "disconnect digit," which disconnects him
|
||
from the last line being monitored, and disconnects him from REMOBS so that
|
||
REMOBS can be reset and be ready for another caller.
