2. A Phun Phield Trip - [1995 TcP/Syn/Ice - E2S] - Written by TCP
-----------------------------------------------------------------
Early this march, we got a keen chance to go on a phun phreaking
phield trip. Here's the inpho.
A. ESS / Midswitches - Revisited
--------------------------------
A few things we discovered on this trip were some new details about
common midswitches. One type we messed with was an older 1A type
midswitch. These were a bit older than other types we've experienced.
The CU (Customer Unit) cards consisted of a module that was 2 PCBs, bolted
together, with a grey bezel in front with connectors/indicators and metal
release latch. The unit had an edge connector in back, weighed about a
pound, and measured approximately 12"x4"x1". Heres some rough views.
P.S. Bezel is pronounced (BEE-zehl).

The newer, more common ESS cards are similar looking to the older
(above) cards, but are smaller in dimension and consist (mostly) of one
PCB. They are 12"x3.5"x2/3" in dimension, and weigh about 6-8 ounces.
They have a white bezel on front with indicators/connectors, and the usual
edge connector on the back. These specifications describe the AT&T cards
like these, and I believe the fujitsus fit the spec as well.
Here are some diagrams. This is where we walked. This is where we swam.
Take a picture here. Take a souvenir. Cuyahoga.

There are a few more types of cards that I've seen, using acronyms as
demarcations. The above two were the ones I could diagram best, I may
update on the others later. Here's what I've seen:
Ac/ Model# Type
AT&T - Newer
------------
CU AUA58 = Control Unit (Series 2)
CU AUA58B = Control Unit (Series 2)
CU AUA52B = Modem unit
LIU AUA64D= Line Interface Unit??
Older 1A type
-------------
DUAL MP CU (WP21 CP) = Dual MPU Control Unit Series 2
DUAL MP CU (WP21C CP)= Dual MPU Control Unit Series 1
