The DSPGenie Mobile TTY Transmission Tester (MTT) was developed by DSPG to support field studies of TTY transmission over digital wireless telephones.

Based on multi-DSP based testing platform it fully emulates the operation of the TextLink 9100 MT allowing automated testing and verification of TTY over wireless networks in field conditions. mtt

The tester can launch bi-directional scripts, which will alternate sides automatically after the GA characters. The text passes via serial connection to the TTY and then via audio connection to the handset. Incoming text is captured from the TTY by the tester.

The M-TTY connects to a host PC via USB 2.0 interface. The DSPG TTY tools application software runs entirely on a host PC under a Windows 2000/XP/Vista operating system. This software fully supports the Gallaudet test data script format and original scoring algorithm.

The M-TTY Mod-3 can operate either in an interactive manual mode or in command-based automated mode, allowing integration with the user’s testing system. Automated mode allows testing over a period of many hours with large amount of data, significantly reducing time to complete set of tests.
