Q. How many of my PSAPs TTYs should we enroll in TTY-PASS?
All, to include spares! According to the ADA;
"Most PSAPs have plans for using back-up equipment in case some of its equipment or telephone lines malfunction, or in case there is a power failure. If a PSAP has such
a plan for voice calls and equipment, it must provide for TTY calls and equipment in that plan. For instance, PSAPs should keep extra TTY equipment on hand, in case the
primary equipment fails, if they have back-up voice telephone equipment for such a situation."
Q. What is TIA/EIA IS-840-A?

the minimum performance standard for Text Telephone signal detector and Test Telephone
Signal Regenerator. It contains strings of Baudot characters with the minimum and maximum

Q. During the TTY-PASS testing process, what can I
expect to see come across my screen?
During the test, as your TTY is receiving and capturing the test script, do
not expect to see any coherent or legible text that you will be able to read. The TTY-PASS script
is designed to run your TTY (and its configuration with the PSTN) through a mini obstacle course by
making it read random text. That being understood, expect to see "gibberish," strings of letters, numbers, various
punctuations and characters that make no sense at all to the observer. When
scoring, it is important that all characters are copied and submitted on the TTY-PASS website
