putting a network in a d1 202 dial-less phone

[BlaneSyma]

I have a dial-less phone that i would like to put a mini network in, i have seen post showing how to wire one with a dial but can not find
one for a dial-less.  My mini network has a green, blue, and black wire and three screws along the bottom. My phone has d1 on the base and has three wires coming from the handset to the phone and four wires coming from  the deskset.


thanks,
Blane

i do not have a subset and this is what my phone looks like on the inside

Blane,

Welcome to the forum.  It sounds like your phone is connected to a subset, in which case, you do not need a mini network.  The subset contains a network.  Does you phone work as it is?

Here are three A.E. mini-network diagrams from the TCI Library:

The mini network has been made in several versions, but has all the same functions.

The blue wire has no function today, as far as I understand, and could be taped or just cut off.
Some versions has terminals instead of some of the wires. 3 one one side, numbered at the printcard with  4, 22 and 23. The last terminal on the opposite side is unmarked, and equals green wire.
On the diagram the red letters refere to equal numbering in my old W.E. 500. (425B network among others) The terminals in a W.E. 500 marked A and K has to be replaced by a capacitor for the ringer. The L1, G, L2 and F terminals are missing, and could be replaced by any suitable way to splice the wires.
As you see of the other circuit diagrams in this thread its not needed with 2 set of hook switches as in the 500. The 3rd set shorting the receiver is not needed either.

Gman -

In the second link, are the labels for the black and blue wires reversed? Or do my glasses need cleaning?

You are right. The Black should be internally connected to red. Not possible to tell without examining the actual PCB.
It may be right, just another layout of the PCB. If its wrong it may cause problems because you should be more than normally observant to see that. (congratulations)

This diagram shows one of the easiest way to build a telephone, with a mini network.


Since the WE 500 seems to be a kind of reference circuit for telephones the letters/numbers in red indicates the terminals on a 425B network.
The dial could be almost any dial on an old phone.

The ringer circuit is simplified and generalized just to indicate any ringer with a capacitor in series. 

All possibilities of partyline billing, and ringing is ignored.
