CISCommonwealth of Independent States (CIS), the former Soviet Republic-3000 is an 8-PSK8-Phase Phase-Shift Keying (3 bits per symbol) Data Modem protocol. It's source is traced to Russia. 3000 is for its 3000 BaudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. speed (maximum speed is technically 9000 bpsBits per second (bps)).

CISCommonwealth of Independent States (CIS), the former Soviet Republic-3000 has been seen acting like 2G ALE, where it has been seen to prelude CIS-128 transmissions and CIS MFSK-68 transmissions like a calling mode.
