Since its foundation, DSPG core competency has been focused on all aspects of Digital Speech Coding and Modem Technology, in particular for use in Mobile Satellite Communication. DSPG continues work in this area, being currently the only company providing independent technical support for AERO-H system used by most of commercial airlines.

As a spin-off from the Digital Speech Coding research, DSPG developed a range of testers to evaluate the voice quality of various voice related products. These testers gave foundation for a range of successful instruments including the BT Network Emulator, Echo Canceller Tester (ECT-1), DSPGenie, VoIP testers and others. Some of these products became the benchmark instruments used by many major telecommunication manufacturers and operators including Alcatel, Nokia, Ericsson, BT, HP, Nortel, etc…..

DSPGenie MTT

The Modem Transmission Tester (MTT) is a multi-DSP based testing platform that allows for highly automated verification of the behaviour of telecommunication network equipment with various types of modems.

DSPGenie M-TTY

DSPGenie Mobile Transmision Tester (M-TTY) fully emulates the operation of the TextLink9100MT allowing automated testing and verification of TTY over wireless networks in field conditions.

DSPGenie MTT V.18 version (USB)

The DSPGenie Modem Transmission Tester (MTT V.18 version) is a multi-DSP based testing platform that allows for highly automated verification of the behaviour of telecommunication network equipment with various types of modems. Configured for use with two-wire modems allow the DSPGenie V.18 MTT to be utilised in most PSTN and PSTN-like environments, where the POTS-type modems are expected.

Echo Cancellation

The ECT tester achieves accurate and repeatable results by implementing all G.168 test procedures digitally. Signal injection and monitor points are provided, allowing analogue measurements.

M-TTY Tools

M-TTY Tools are being distributed to the TTY Forum to help companies testing TTY over wireless networks in field conditions.

TL9100MT

The TextLink 9100MT is a modified version of the standard textphone designed for the purpose of testing with the Gallaudet/DSPG software package.

DSPGenie TNE

The Telephone Network Emulator (TNE) surpasses the functionality of existing, high-cost test equipment, and should fulfil a much-needed role in the testing of high-speed voiceband data modems and fax terminals.
