TTY And TRS

Definition of TTY & TRS

Teletypewriter (TTY):

  • TTY allows people who are deaf, hard of hearing or speech impaired to use the phone to communicate by letting them type messages back and forth to one another, rather than talking and listening.
  • TTY is required at both ends of the conversation in order to communicate.

Telecommunications Relay Service (TRS):

  • TRS allows hearing-impaired and speech-impaired people to communicate via text phone with non-impaired phone users who don't have TTY.
  • Each state has developed its own TRS program, so specific access numbers and contacts vary. The nationwide standard access number is 711.
  • Local phone service providers translate and route 711 calls to the TRS provider for that specific state.

Calling 911 with TTY

To avoid delays, dial 911 directly from the TTY. Don't dial TRS using 711. All E911 answering centers have TTYs. The customer's TTY should send audible tones that indicate to the 911 operators that a TTY must be used to answer the call.

Problems with TTY

A problem called "garbling" may be caused by call-waiting tones, loud background noise, low power on the TTY, inclement weather, cracked acoustic couplers, automated voice messages transmitted by the TTY, line static, improper TTY settings and TTY shifting between letters and numbers.

To clear any garbling:

  • Try typing AAA111 or hitting the space bar. This may clear the garbling.
  • If you're using Turbo Code, change setting to Baudot.
  • If using acoustic coupling, ensure the handset is sitting securely in the acoustic cups.
  • If these steps don't help, hang up and redial as a last resort.
  • If the issue persists, contact us.
