  • Legacy TTY Service

    The Comtech Telecommunications SMS9-1-1 fully supports a text to TTY dynamic live conversion, which allows PSAPs to continue using their existing CPE equipment for interacting with the public’s text messaging. This service treats text messaging as existing TTY traffic.

    Key Benefits

    • Utilizes PSAP’s existing TTY equipment, requiring no install for the PSAP
    • Provides TTY dialog control on behalf of the wireless subscriber who is simply text messaging
    • Follows the same trunking path that voice calls follow today
    • Presented as a session to the PSAP personnel who still control the life of the session through existing known controls
  • Transitory IP-based PSAPs – GEM9-1-1® Service

    The GEM9-1-1 service is a secure web-based service that allows the IP-enabled PSAP to easily deploy and utilize the service through their internet connection. This allows for multiple-PSAP personnel management of incoming text sessions and visualization of the location of the wireless subscriber on a graphical map.
