A TDD/TTY (Telecommunications Device for the Deaf/Text Telephone Yoke) unit is essentially a physical device that looks much like a simple computer terminal and uses graphic communications in the transmission of coded signals. Nextalk/Textnet services enable PCs to function like a TDD/TTY unit and allow callers to be routed to any user within an agency or at other agencies. Callers may leave messages that can be forwarded through email and outgoing calls can be typed through the PC.
All State agencies are required to be able to communicate with the deaf and hard of hearing so it is expected that each agency would have at least one unit to communicate with such a caller.
BCCS telecommunications services are available to all state agencies, boards, commissions, universities, offices of the Illinois House and Senate, and Constitutional Officers.
