Here's the German Phone, just got it

[mienaichizu]

Hi guys,

here's the phone I was talking about on my previous post, unfortunately it is not red. I already started cleaning and testing it but there seems to be a problem. It is working but again, my problem with my other phones, dial tone can't be cut. It can receive calls, it rings but can't dial a number. What can you say guys? Anyone has any experience in refurbishing this kind of phone? can anyone help me?

Wow, nice ivory bakelite. I would have no idae where to start to wire this puppy up.
If you get it going, please let us know!

Very interesting phone!  I can't help you figure it out much as I don't even know what it is.   

Of course there is the old "plug and play" method, just start moving wires around and see what happens.  Not exactly an elegant solution, and probably playing with fire, but so far I've managed to not melt anything doing this with a few of my oddly wired up phones.

Ramil, is that a Siemens and Halske?  Oh and Merry Christmas by the way.  I enjoyed your blog, too.  -Matt

Here is a very interesting article concerning Bakelite colors.

I've got a couple of those around.  We used to refer to them as "the longitudinal handset Siemens."  I've also got a bad xerox copy of a Siemens technical journal article on them.   Siemens also made a conventional housing (similar to but NOT the same as the German 611 type housing) for the same chassis as used in the longitudinal handset model. 

About the dialing problem:  Most of the German dials (Siemens, DFG, and some Eastern European versions) use a three-bladed interruptor cam that comes between the impulse contacts.   Look closely to see that the contacts are breaking properly when the cam operates.  If they are, then your trouble is in the wiring, and may be just a matter of hooking up the line cord to different terminals. 

Another trouble source for all rotary phones is VOIP-based phone services (someone around here said Comcast is guilty of this) that don't accept pulse dialing.  The way to tell is, tap the hookswitch briefly to simulate dial pulse digit 1, and see if that breaks dial tone.  If it doesn't, and you have IP carrier, that's your problem, in which case a pulse-to-tone converter (Mike Sandman) or a Panasonic hybrid PBX (I have a few to spare, also widely available on Ebay) will do the trick.
