Different TACS-Systems GSM RNE Fundamentals ▼ ETACS - Extended TACS ■ Current UK system that has 1320 channels (1278 voice, 42 control) and has replaced TACS as the UK standard ▼ ITACS and IETACS - International (E)TACS ■ Minor variation of TACS to allow operation outside of the UK by allowing flexibility in assigning the control channels ▼ JTACS - Japanese TACS ■ A version of TACS designed for operation in Japan ▼ NTACS - Narrowband TACS ■ New system that has three times as many voice channels as ETACS with no loss of signal quality Mobile Radio Network Planning 3FL 11820 ABAA WAZZA ed01 26
