To communicate voice and data simultaneously the ordinary modem leaves a lot to be desired. (Jul, 1984)

Introducing the Tel-A-Modem.

Now you and your personal computer can talk on the same phone at the same time.

Let’s say, for example, certain data you were transmitting via your personal computer to a remote computer user needed some verbal explanation to go along with it. With the ordinary modem it couldn’t be done. Not simultaneously.

You’d have to first call the user to inform them that data was coming. Hang up. Re-dial in order to connect modems. Transmit the data. Hang up. And then call back with your explanation. If you had additional input to transmit and discuss, you’d have to begin the whole process again. Talk about frustration.

Code-A-Phone’s solution to this problem is the Tel-A-Modem. An innovative two-line desk telephone integrated with an intelligent modem capable of transmitting voice and data simultaneously.

Of course, the genius of Tel-A-Modem doesn’t end with its unique communication capabilities and state-of-the-art convenience.

Specially designed for use with RS-232C compatible computers and terminals, it offers a full spectrum of both telephone and modem cost effective features, including: single button selector for voice or data on either line; full-duplex mode; automatic answer/origi- nate modes; 300 and 1200 baud data transmission rates; automatic selection of baud rates; switch dialing for tone-dial or pulse-dial systems; memory autodial; and modem status LEDs.

So much for words.

    How is that different from having a phone and a modem plugged into separate lines?

    GaryM, in the 1980s in the US most RBOCs still wouldn’t let you plug their phone lines into any equipment not made by them or by their contracting technology companies (Westinghouse, GE, etc). As a result, it was kind of special not to have to lift your handset into an acoustic coupler. Back then you would have had to have two voice phones and an acoustic coupler. The fact that this had an auto-answer mode hints to me that it was aimed at systems operaters.

    Or “SysOp” as we kids used to like to call them.
