Software implements universal telephone modem for
data rates form 300 bit/s to 14.4 kbit/s, for leased and switched lines.
We offer version that can serve more then one channel in single DSP chip.
• DTMF transmitters / receivers.
Software implenting DTMF signals transmitter and receiver.
We offer version serving 30 channels in single DSP chip.
• Parallel RF modems
Software for data transmission through multiway digital radio channels. One of methods for data transmission in such channels is lowering modulation speed and introducing multichannel transmission (several bits parallely).
• Low speed vocoders 1200/2400 bit/s
Software for low speed voice codecs in LPC technology.
