that allows people who are deaf, hard of hearing, or who have speech or
language disabilities, to communicate by telephone. Your device is compatible

to ensure that it is compatible with digital cell phones. Your phone and TTY

If this cable was not provided with your TTY device, contact your TTY device
manufacturer to purchase the connector cable.
