Billing pulse frequencies of 12 and 16 kHz are filtered out by the digital part of ALIS. No
external components are necessary for blocking.

10.5.1 Functional Description
In sleep mode, any signal greater than a typical value of 18 volts will be detected.
Depending on the No_auto_ring bit, either an interrupt will occur or ALIS will be switched
automatically to ringing mode. In this mode, the ringing signal will be passed to ALIS-D
and decoded. If the ring burst does not meet the programmed requirements within a
programmable time, ALIS will return to sleep mode. After a latency time, ALIS will
decode the caller ID. When the second valid ring burst occurs, a ring interrupt is
generated, signalling the incoming call to the host (see “Flow of Ring Sequence and
Detection” on page 65)
