Yep, Detroit had a panel office in the main Bell building downtown. The exchange was Exeter, and used only internally in the building. The others were #5XB until the advent of ESS. I was a teletype/ data installer/ repairman downtown servicing the stock markets and airlines reservations centers. Then the opportunity came to train as one of the 1st ESS Switchman which I undertook. The self taught school (supervised in residence) lasted 6 months quaranteened in a small cubicle reading lesson plans each day and taking tests weekly to progress further in the course. We installed several offices in the area (ESS-1 w/ signal processer). Then one day I was given the opportunity to be an apprentice building trades electrician at substantially better wages & benefits with the International Brotherhood of Electrical Workers. Bye buy Bell-never looked back-best move I ever made. Retired with a Real pension worth contributing to. Forty years did take its toll on the old body. Heavy construction is no picnic. Can't lift my 28ASR, but then, I don't know anyone else who can. Rick K8PJQ

Amazing!
for anyone into TTY in north Texas, I know where a couple of Navy
rackmount demods are along with the TTY units, if they are still there.
Could be had for little.

Once we have the TTY land line link working between the two stations it will be another step back in time to the days when such links were common. When that link is inaugurated - this year we hope - we'll be communicating the way transmitting and receiving stations did in the golden years.

You both have touched some dear remembrances. Aside from the Exchange names
in Detroit (and my home town further north) I remember the mechanical
aspects of my early days. When I started in 1967 in Michigan Bell, only a
couple Panel Offices were left in Detroit - yeh, 11' high & 17' to the
ceiling!! Those were the offices with the three tier Main Frames - some
real jumper nightmares. They were in operation for a few more years after I
started since I remember the Project Engineers talking about maintenance on
the Panel machines - Waxing to reduce switching line noise.
RE: Rotary switches; most of the rural (CDO - Community Dial Offices)
were rotary in Mich. For years I only knew them as 'rotary' until I went to
an independent office and a local switchman talked about the x-y Stroger and
I got a history lesson. They ALL sure had a distinctive sounds. Speaking
of sounds, I remember a 5XB office in the suburbs (Utica, MI) that around
11:30 would go almost silent, then at 11:55 come back up with a roar of
switching traffic noise. Very interesting.
I started off with the company I was doing N-Carrier Impulse Noise
measurements as management. At first it was N1, then N2 & N3 - the whole
reason for the surveys and follow-up repairs/bonding/grounding was the
forthcoming data network - boy, the TTY at 150 baud was a busy piece of
machinery to me. Then 300 and then the thermal printers at 1200 - and so
on. At one point, I managed a few programmers and we had a print station
that had a drum printer, full width computer paper, had a row of hammers
that would pick off the characters as they spun by. Our printer ran as a
remote off a main-frame - the controller was a PDP-8. We ran a construction
Budget program for the company that ran of the company's mainframe printer.
A laser printer, would have a transparency that would 'flash' the form image
on the paper, then print in the characters on the paper - pin feed
continuous sheets in an oversized box (taller than normal). Would empty the
box in around three minutes. I was impressed. This was probably back
around the early 1980s.
Really something when you consider we've grown up (as kids 5-12) during
the vacuum tube days, matured (teenage 13-18) during the solid state
evolution, and watched the data/computer revolution (20-current). What a
marvelous time.

FYI:
One interesting tidbit as far as the mobile telephones were concerned
were they easily could have been converted to IMTS or dial. However,
the traffic engineering for the network would have required getting rid
of half the customers. Net result, the telcos stayed manual. We had
the same issues here in Detroit. Only the UHF system or MK was dial,
the VHF system or MJ remained manual into the late 1970s or early 1980s.
The operators could sort the traffic out quicker. There were regulatory
issues as well.

You can still see a panel switch at the museum of communications in
Seattle.
I missed out seeing our last one at the EDgewater CO in Chicago before
it was removed.
The switch frames were eleven (11) feet tall and the switch mechanism
was referred to as a "Monkey on a Stick"
Panel offices used a craftsman that no other type offices used.

I grew up in Los Angeles - which was somewhat of the "wild west" when it
came to phone service and phone companies. In most of the country
- a large city - even a region was usually served by one company -
usually a Bell company of AT&T. Los Angeles, on the other hand had
several major players - not always playing well together. Los Angeles
itself was (mostly) Bell / AT&T - using Western Electric equipment.
However - many of the surrounding communities - such as Long Beach,
cities of the San Gabriel Valley, etc. - were General Telephone
customers - mostly using equipment by Automatic Electric. That made for
some strange "interactions" here and there...
In the early 1950s - within LA itself - you only had to dial 5 digits
- and they were listed (usually) as (something like) 7-1234. It was
when you called some of the suburban areas - like Long Beach, Norwalk,
etc. you had to use the Exchange "pre-fix". Norwalk was University,
Bellflower was Torrey (which you might note is NOT one of the favored
Bell pre-fixes - not surprising since it was GT); West Covina, La Puente
and the un-incorporated areas in that area were Edgewood; Both
University and Edgewood are on the "Bell list".
Another interesting "thing" out of that era - was that even as mobile
phones and the age of digital communications were getting underway in
the late 1970s - calls were still being connected by hand in Bell's
Avalon (Santa Catalina Island) exchange via a local cord switchboard.
Another "fallout" of the mixed equipment - I had been in a couple of
switch exchanges - and had never seen a rotary stepper... GT used
something called a panel switch in many of it exchanges - which steps in
the X and Y plane - rather than a half-circle like a Strowger.
yeah - brings back a few memories!

Pshaw... speak for yourself, some of us NEVER grew up. ;-)
But at 56, yes, I fully understand what you're saying having done that.
Side note: After 25 years in the aerospace industry chasing the foreskin
of technology, I am now self employed fixing vacuum tube radios.
The more things change, the more they stay the same.
