Special Services for the Disabled
The Deaf and Disabled Telecommunications Program (DDTP) is a California State mandated program established by California Public Utilities Commission and has two components: the California Relay Service (CRS), and California Telephone Access Program (CTAP).
CRS helps establish a communication link for a hearing or speech impaired person to communicate with all other telephone users.
Features of the Relay Service include:
- 24-hour service, seven days a week,
- Toll-free number to reach the Relay Service,
- No extra charge for using the Relay Service,
- If long distance charges apply, they will be billed at the carrier or local telephone company rates.
To make calls, the hearing or speech impaired caller will use a Telecommunications Device for the Deaf (TDD/TTY), which resembles a portable typewriter. The service will relay the caller’s typed messages through specially trained personnel who will handle the calls. The system also works in reverse, allowing a person without a TDD/TTY to call a person who uses a TDD/TTY.
