be heard over conventional telephones or read via a TTY device's
data terminal with a keyboard for text messages read by persons
with deafness or hearing loss. TTYs generally consist of a keyboard
and display screen. (Contact information for all devices and manufacturers listed at the end of this guide under Resources and Vendors.)
TTYs can be used with telephones,
over PC modems, and with cellular telephones. Some support voice
carry over (VCO) for those who wish to speak, and then read the
typed responses sent from the other person. VCO also comes in portable

the hearing loss. An inline amplifier is very versatile because
it plugs into most telephone jacks through the curly cord and certain
models are very powerful. Consumers benefit from additional features
like tone control or variable ring sounds, flashing lights, and
large dial buttons, or an audio jack to connect to an additional

or cordless amplified telephones also are handy. Be sure to check
out a variety of devices to learn what is most useful to you. [Also
