4. R1: Receive signal 1, R2: Receive signal 2, Ts: Side tone signal, RT0: DT, PDT, SDT, CRBT, and IIT, RT1: RBT, BT, and T250, FT:
5. Output Signal RPO is the signal added by the signal indicated in "1"s in each column.
6. "0"s of Control Signal NTTC are equivalent to "1"s of the Output Signals FT and PBr, and "1"s are equivalent to "0"s of Output Signals.
7. Control Signals MUTN and NTTC are the internal control signals. Initially, both signals are in "1"s. MUTN is controlled by PBTC
FTONE and PBr: PB acknowledge signal.
of controlling the PB tone.
MUTN = 0 when PBTC = 0. MUTN = 1 when PBTC = 1.
NTTC is controlled by PBTC of controlling the PB tone or NTTC of controlling the function key acknowledge tone, but the NTTC
data written later is valid.
NTTC = 0 when PBTC = 0. NTTC = 1 when PBTC = 1.
