A close view of the Selector may be seen under.

The selector is named Skancke selector.

2 Norwegian articles from 1929 and 2 pages from a 1938 catalogue is here:

Work continues on the British Strowger Demo switch...

A lot of progress made on my British Demo switch lately, perhaps the most so far. today.

The past couple of weeks have been spent getting the switches working. Having been in poor storage for many years, they required quite a bit of work.

Today, Earl Pauley was down and we put the banks on the two selectors and wired the banks, and now one can dial through the two selectors to the connector. I need to get another UK bank hanger for the connector before I put its bank on, due to the fact it is badly twisted, and the way it is, the bank won't line up correctly with the connector.

However, the connector is responding  to pulses passed through the two selectors as it should be.

for more details.

Thank you so far, I have got some good hints, and now we got the numbers according to the right numbering plan.

The English voice is from C*NET archives, the Norwegian is generated by
http://www.acapela-group.com/text-to-speech-interactive-demo.html
and modified in Audacity.

This has also made made it possible to generate a suitable dial center based on local and American traditions.
We have no tradition of using letters, but it happends to match MUseum 2476 I could'nt resist..


Of course with a little C*NET twist, using a simplified logo.  The TCI logo is far too detailed to be easy to put in a small dial center.

Looks like your Step by Step demo is well under way! First picture looks as though it might be a line finder but only has a 2 section bank rather than 3 sections? Should work for your Demo requrements anyway.

yeah that is a linefinder with a 2 section bank.

Not if you are referring to mine. It is a 3 level bank.

Hello All,

Another switcher here. I retired from Verizon after a 32 year career almost all of it in the CO as a switchman and the last 13 years as a CO supervisor. I started with New York Telephone working in panel and cross bar 1 & 5 offices in Brooklyn NY. Worked in the mid 1970s in Lake Havasu City AZ in a Stromberg XY office with a North Electric 400D ticketer (reed core memory) and then moved on to Continental Telephone in Cazadero CA and their XY COs. Also worked in AE SXS. As CO supervisor with GTE in northwest Indiana saw the end of SXS switching in the mid 1990s. What I could of and should of saved back then makes me cry. All I have is a test stand and a few AE switches.

I would like to buy a SXS demo set up or an operating system in 1 or 2 racks. Thanks

I've placed a few calls into your switch. There is a long time delay before your Mitel dials out.
When calling the 2 digit stations I do not receive any RBT. The single digit appears to work ok.

The RBT are depending on the ringer load of the line. 14 and 15 are usually connected.  The signal are 25HZ and harmonics of this generated by a vibrator.  The delay from the Mitel are approx 7 seconds from the last digit.

I got a problem here, when I am dialing 2 for line 2 it rings at 11. Should it be a capacitor, or something timing the delay between first and second digit?  http://tinyurl.com/ovgletf

1 + 1 = 2 !

Seems acceptable.  LOL.


Seriously,   it seems the dial is either very much too slow, or the inter-digit delay logic is indeed broken.
Do you have an understanding yet of the diagram?  It is way too hard to decipher in this low resolution.


dsk

This is the documentation available, The dial are good, and I have tested several phones on this line, and this phone on other lines. It has to be the inter-digit timer. And I am not able to determine witch capacitor to look for.  Maybe better resolution here? http://tinyurl.com/o9gf5hx
