the collector is asking "what system was this console used in?"
It looks like a modified call director to me, why I put it here
I figured Ed would know ?

Attendant console for a 756 PBX.

And it probably still works as well as it did the day it was installed.

Jeff, thanks for the compliment, but Arthur holds the title of 'most knowledgeable' with regard to this stuff. I'd be happy if I could remember half of the things that he's forgotten.

Ed, I only remember the unimportant stuff.

As Mark Twain said, regarding getting old and forgetful:

"At my age, my memory has improved to the point that now I can remember things that didn't even happen."

How many 25-pair cables fed that console eh
Posted By: Arthur P. Bloom Re: One for Ed - 10/03/12 02:52 AM
Upon further review, it has 70 DSS keys. The 756 would have 80.

It has no supervisory lamps next to the line keys, so it's not from a PBX.

We think it's a supervisory console for "general service" use. These were used in various central office or business office applications. The big red lamp at the left is a signal that lights when a subordinate needs attention.

It probably had a "5-finger" (125-pair) mounting cord.

I like the frowny face above the red lamp!

Art,

Didn't they drop the violets out of the multi fingered cables?
Posted By: Arthur P. Bloom Re: One for Ed - 10/08/12 06:07 PM
Good point...Not sure. Subscriber station Call Directors used that method, but some PBX consoles didn't. It depended upon the number of lamps, etc., in the DSS fields.

Call Directors used one finger per strip of 6 keys, so only 20 pairs were needed in that application, but PBX consoles used more pairs, for features such as the trunk keys, with two supervisory lamps per key.

I'll see if I can dig out some BSP's for PBX consoles and take a look.

Yes. What they called "Call Director Cable" was 100 pair, 5 binders with no violets.

This is an old thread... but I thought I'd share this video that features this PBX console, or one similar.
