REXT-EN
Enables the use of an external ring-signal generator. The synchronization
is done via the RSYNC pin and the ring-burst-enable signal is transferred
via the IO1 pin.
REXT-EN = 0 External ringing is disabled.
REXT-EN = 1 External ringing enabled.
SOFT-DIS Polarity soft reversal (to minimize noise on DC feeding)
SOFT-DIS = 0 Polarity soft reversal active.
SOFT-DIS = 1 Polarity hard reversal.
TTX-DIS
Disables the generation of TTX bursts for metering signals. If they are
disabled, reverse polarity is used instead.
TTX-DIS = 0 TTX bursts are enabled.
TTX-DIS = 1 TTX bursts are disabled, reverse polarity used.
TTX-12K
Selection of TTX frequencies
TTX-12K = 0 Selects 16 kHz TTX signals instead of 12 kHz signals.
TTX-12K = 1 12 kHz TTX signals.
