Western Electric D1 User manual

Western Electric D1/B1 Rotatone®Installation with an AE Mini-network
First, secure the AE mini-network and
Rotatone module to the base plate as
shown. This will allow the cradle plunger to
clear and avoid entanglements with the dial
switches.
It may help to first place the units in the
phone before the dial is installed, then reach
though the dial opening to mark the area.
Place the dial in to make sure it clears.
Secure the mini-network and Rotatone unit
with 3M Outdoor (double side) Mounting
Tape. Double thickness is recommended so
that solder points don't short against the
base plate.
Check again to make sure the plunger
clears, then install the dial.
Note placement of the plunger leaves. You
got to do what you got to do to use the tight
space inside a D1.
At "A", use electrical tape to insulate the
contact leaves between the "BK" and "Y"
terminals ONLY.
At "B" the "G" and "W" contacts will be used
for the switch hook.
At "C" the "BK" and "Y" contacts will be used
for the transmitter. These will need to be
electrically isolated because the 5.1v Zener
must be placed in series for the transmitter.
The Y terminal screw will also be used to
mount the polarity guard.
At terminal "G" attach Red line cord (L2).
At terminal "W" attach switch hook jumper.
At terminal "BK" attach AE network Green
wire AND one end of the Zener.
At terminal "Y" attach the other end of the
Zener, mount the polarity guard, and the
BLACK handset wire. Note placement of
Zener under the polarity guard at "D".

Wiring the Polarity Guard:
At screwpoint "E" attached Green Line Cord
(L1).
At screwpoint "F" attach switchhook jumper
from terminal "W".
Wrap the polarity guard with electrical tape
so the screwpoints don't short against the
baseplate. One secure layer will do it. .
White polarity guard wire connects to
network White wire or terminal.
Green polarity guard wire connects to
network Pink wire or terminal.
At terminal "B" attach both handset RED
and network Black.
At dial "BB" attach network Yellow (In this
diagram I've used a gray jumper from the
network terminal.)

Now it's time to finally attach the Rotatone
unit!
Rotatone Blue attaches at Network white.
(Along with the polarity guard white).
Rotatone Orange/Red attaches to Network
Pink. (Along with the polarity guard green).
Connect the dial:
Handset WHITE to dial "W"
Rotatone Orange to dial "Y".
Rotatone White to dial "B".
Network Yellow (or jumper) to dial "BB"
Rotatone Brown to Dial "R".
Note that the stiff wires of the Rotatone unit
go on top so that they "hold down" the other
wires and avoid entanglement with the dial
contacts.
Finally, check that the Yellow/White/Pink
terminal connections don't short against the
Terminal B when the phone is closed. Bend
them 90º and/or insulate with electrical tape
if needed.
Close up the phone and you're done! Enjoy
your DTMF D1 or B1!
