Apple iPhone TTY Adapter

Overview

This adapter lets you use your iPhone with standard TTY devices. Just plug the cable from your TTY device into one end of the iPhone TTY Adapter, then plug the other end of the adapter into your iPhone.

TTY is an abbreviation for TeleTypewriter. It’s a device used by the deaf to “text” messages across an analog telephone line. These days, text messaging has just about obsoleted the device however it remains well-suited to the task.

Because the TTY was originally designed for an analog phone system it worked very much like an analog modem; converting “text” into “sounds” that were then re-interpreted back into text at the receiver’s end. Both parties of the conversation would have to have a TTY machine.

This adapter allows a person to connect a TTY machine to the “analog” audio input and output of the phone.
