Keypad and headset looked like payphone keypad and headset. Had an black on green backlit LCD display. Forget what it displayed before anyone picked up the phone but would print numbers dialed as dialed. Had visor over display to reduce glare and prying eyes, I suppose. If I remember correctly, instructions were printed on the actual unit.
4. Closed circuit television surveilence which worked only with cable (Americast (http://www.ameritech.com/content/0,3086,6,00.html) (Unknown type model)
Camera pointed at TeleEntry 2000. If I remember correctly it used channel 3.
Location200 Arlington Place Apartments, Arlington Heights, Illinois
To unlock the entry doors (not individual apartment doors) from the outside of the building, residents would use the wall switch reader and proximity tag. They would wave the tag in front of the wall switch reader and the door would quietly buzz and unlock for about 8 seconds.
They would look at the TeleEntry 2000 fumble with it and THEN read the instructions (heh). But seriously.. They would look up the three digit "extension" (not really but best analogy I could come up with) on the directory on mounted on the wall (not computerized) corresponding to the resident they want to reach, use the TeleEntry 2000 to dial that code, the resident would then press 7 or 9 to remotely unlock the door, the door would quiety buzz for 8 seconds and automatically unlock.
Discoveries:When a visitor would 'call' from the front door using the TeleEntry 2000, (847) 506-1230 (This is from memory from 3 years ago so don't quote me) would appear on the caller ID. At the other end of this number was a modem. When someone was connected to that number, when visitors picked up the handset of the TeleEntry 2000 downstairs they could hear the modem and were unable to use the TeleEntry 2000. When dialed into the modem (at 7-e-1 I believe, but again.. memory.. 3 years ago), the output would look similar to the following (memory.. 3 years ago.)
102398 11:51:23 123456 3
The first number was the date. Any single digits were preceeded with a zero (IOW, March is month 3 and would be seen as 03)
The second number was the time in hh:mm:ss format.
The third number was the six digit number printed on the back of the residents proximity tag.
The fourth number was the door number. For this building (may be different with others)
1 was the front door
2 was the back door
3 was a side/back door
If a visitor 'called' a resident with the TeleEntry 2000 whose phone line was busy, they would hear the busy signal as well as the name and number delivery ad for Ameritech one would hear as they made a regular phone call with a regular phone
If I remember correctly, when you picked up the handset on the TeleEntry 2000, you would hear a normal dialtone and not a pbx 'dial tone.'
There was a code the mailman used to dial into the TeleEntry 2000 to open the door without being 'buzzed in' by a resident. Never got around to shoulder surfing it.
Sometimes when you dialed the number that showed up on the caller ID for calls from the TeleEntry 2000, instead of hearing the modem, you could eavesdrop :)
I still have a proximity tag somewhere... If I find it, I'll dissect it and take pictures.
