Definition: V.26ter
An ITU standard (1984) for asynchronous and synchronous 2,400 bps full-duplex analog modems using DPSK modulation over dial-up and two-wire leased lines. V.26ter included a 1,200 bps fallback speed and used echo cancellation, permitting a full-duplex modem to send and receive on the same frequency.
