The Encore Relay technology for Fax is designed around a flexible, programmable architecture, in which the basic modulation/demodulation protocols and T.38 compliant relay state machine are both implemented on the DSP. This technology implements a wide range of ITU-T modulation protocol standards for fax modems. The basic datapump has been exhaustively tested on a telephone network emulator for various line impairments and for interworking. The relay software has been tested against typical internet impairments such as packet loss, delay, jitter etc.
