Tester Operation

The DSPGenie M-TTY consists of two DSP modules implementing separate Baudot/CTM soft-modems A and B. Each of the modems is fully compatible with TextLink 9100 MT.

Modem A is always used as a Calling party and Modem B is used as an Answering party.

The USB interface connects the M-TTY to the user’s laptop or desktop host PC running DSPG’s TTY tools application software.

The TTY tools DLL library provides functions and commands to allow automated operation within the user’s test environment.Additionally, these commands can be executed remotely from another computer using the TCP/IP and specific client/server protocol over the LAN.

Block diagrams below show the compatibility between testing environment using TextLink 9100 MT and DSPGenie M-TTY:
