Telecommunications for the Deaf and Hard of Hearing, Inc. (TDI)


TDI was established in 1968 originally to promote further distribution of TTYs in the deaf community and to publish an annual national directory of TTY numbers known as The Blue Book. Today, it is an active national, nonprofit advocacy organization that focuses its energies and resources to address equal access issues in telecommunications and media for four constituencies in deafness and hearing loss: deaf, hard of hearing, late-deafened or deaf-blind.

  • Hearing Aid Compatibility Act of 1988
  • The Americans with Disabilities Act of 1990
  • Television Decoder Circuitry Act of 1990
  • Telecommunications Act of 1996
  • Section 504 of the Rehabilitation Act of 1998
  • Communications and Video Accessibility Act of 2010

The Community Emergency Preparedness Information Network (CEPIN) project is not TDI’s first federal grant to strengthen the scope of emergency preparedness for deaf and hard of hearing people. In 1994, TDI received a grant from the Department of Justice to develop TTY training kits called Emergency Access Self Evaluation (EASE) kits. EASE kits were used to train 9-1-1 centers and other public safety answering points on handling incoming TTY calls. TDI contributed to the 2004 Emergency Preparedness and Emergency Communication Access: Lessons Learned Since 9/11 report, which documented many of the issues addressed by the CEPIN project grant.
