When PBTC = 0, the PB tone is output from the transmit path and the
receive path RPO.
The conditions of internal control signals are MUTN = 0 and NTTC = 0.
When PBTC = 1, the PB tone is output only from the receive path
SPO.
The PB signal is not output from the transmit path.
The conditions of internal control signals are MUTN = 1 and NTTC = 1.
When the initial state is set and the PB tone is suspended,
the conditions of internal control signals are MUTN = 1 and NTTC = 1.
