Suspends the PB tone

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.
