Notes:
1. MUTN of Control Signal is set by PBTC (DB4).
MUTN = 1 when the initial state is set. MUTN = 0 when PBTC = 0. MUTN = 1 when PBTC= 1.
2. SG: Signal ground, T: Transmit signal, TMX1: Transmit addition signal 1, TMX2: Transmit addition signal 2, PBt: PB signal, Ht: Hold
tone signal
3. The output signals of T1O and T2O are the signals added by the signals indicated in "1"s in each column.
