A friend of mine has acquired some 300/1200 baud modems built by
Western Electric.  I have been trying to help interface the
modem to his personal computer.  I can't even figure out where
to connect the telephone line.

The modem is 2 inches high by 6 wide by 11 deep.  It has 5
push-push type switches on the front and a number of indicators
behind the red plastic faceplate.  It says "Dataphone 300/1200" on
the front faceplate plus the Bell symbol.  On a label on the bottom,
it says "Data Set 212A, AR Options" and has a chart showing internal
DIP switch settings for various options.  Another label says:
"4702 Data Mounting
P/O Data Set 212A OR AR Type
Series 1   81 MG 02"

There are two 25-pin data connectors on the rear, one male and one female.
I cannot see any place to connect the phone line anywhere, inside or out.

If anyone could furnish the necessary
interfacing information I would certainly be indebted.  I am hoping that
I can talk my friend into giving me one of these modems so I am especially
anxious to be helpful.
