Context

Country: Canada
State/Province: Ontario
Period: 1930's +; after 1967 as part of telephone communications system for deaf and hard of hearing people.
Canada: According to Ms. Vatcher-Ryan, in Canada Bell would provide teletypewriter so that deaf person (such as Ms. Hebert) with a modem could communicate directly with others with same equipment. Originally this equipment was used by Ms. Hebert's mother, then by Ms. Vatcher-Ryan.
Function: Used with specialized frequency-shift modem 2000.0170 to enable deaf and hard of hearing people to communicate using ordinary telephone lines. Modem converted TTY signals into tones that could be carried by voice band of telephone line.
Technical: Possibly modified WWII vintage teletypewriter used with a modem developed in 1963-1964 by Californians Robert Weitbrecht & James Marsters, both deaf or hard of hearing; this enabled two individuals to communicate using two teletypewriters. Each user had TTY and a modem. American system used surplus teletypewriters released after 1967 by AT&T for that purpose.
Area Notes: Unknown
