- What is a REMOB?
-
- Technically, REMOB stands for REMote Service OBservation System, but, in plain,
- everyday English, it's Ma Bell's way of watching what you do on the phone.
-
- This is far more dangerous to the phreak than the DNR (Dialed Number Recorder),
- which begins recording as soon as you pick up the phone, to catch the numbers
- you dial and stop after about 20 seconds or so after you're done dialing.
-
- The REMOB allows anyone to tap into your line, without clicks, beeps, noises,
- volume or voltage drop (sorry guys, but those voltage meters on the line won't
- cut it here), and most importantly of all, it can be done WITHOUT the need of a
- hard-line tap. That's what makes the REMOB so dangerous - it's done from
- remote. In other words, from any touch tone phone.
-
- The REMOB was meant for observational purposes, so when designed, it was
- devised so that linemen and phellow Telco employees couldn't indiscriminately
- access anyone's line and make calls off of it. Therefore, the signal coming
- out of the mouthpiece and keypad of your phone will not make it to the target
- number's end. So, he cannot hear you when you lock onto his line, or drop off.
- This isn't a gizmo like the diverter or the gold box; it's totally different.
-
- When you call up the REMOB unit, you will hear a tone which lasts for about 2
- seconds. You then have about 5 seconds to key in the access code, or the REMOB
- will hang up. The access code is different, depending on the unit, ranging
- from two digits up to five, but most commonly being four. When entering the
- code from the touch tone keypad, be sure to hold down each digit for about a
- second for the unit to receive it. When you key in the correct code, you'll
- hear another tone and the unit waits for the 7-digit target telephone number.
-
- But here's the catch: Due to the volume of exchanges present within an NPA,
- the unit itself is limited to covering only a small region, so it doesn't even
- bother to prompt you for the extra three digits. In large cities, many units
- may be needed to cover an entire NPA, and so, your REMOB may not be able to
- reach every one you try. That means that you'll most likely need more that one
- REMOB to cover one area or city. This also means that it may not be accessible
- to out-of-LATA numbers.
-
- After dialing the target number, if that line is being used, you'll instantly
- be connected with the conversation, though they, as I've said before, will
- never know you're there. If you should lock into the target number when it's
- not in use, you'll hear a steady idle tone, rather than hearing the actual dial
- tone, if you had a direct line tap. So, with the REMOB, you don't actually
- 'connect' with the customer's line; you simply monitor it. When the customer
- picks up the phone, you'll hear their dial tone, the person dialing the number
- and the conversation, and then the person hanging up again. Theoretically, you
- could stay there all day, but that's not too smart.
-
- Though your keypad may not be heard by the line you're monitoring, the REMOB
- itself does recognize the tones. To disconnect the unit from the current tap,
- enter a digit, most often the last digit of the access code. After you
- disconnect, you'll get the second tone again, prompting you for another seven
- digit number; you don't have to reenter the access code. When you're done with
- the REMOB altogether, instead of hitting the last digit of your access code to
- reset the unit for another number, you must enter another digit, which varies
- from unit to unit, to disconnect from the unit totally so it can be used again.
-
- Be sure that you don't just hang up from the REMOB, or it will stay connected
- to the line you set it for, and will not accept other calls until reset
- manually, which will draw attention to it, your target and most important of
- all and most likely, you.
