4. If a non-compliant parallel device is present, a reply
tone is not sent by the host tone generator, and the
CO does not proceed with sending the CID data.
5. If all devices on the line are Type II CID compliant,
the host must mute its upstream data output to avoid
the propagation of its reply tone and the subsequent
CID data. After muting its upstream data output, the
host processor must then send an
acknowledgement (ACK) tone back to the CO to
request the transmission of the CID data.
6. The CO then responds with the CID data. After
receiving this, the host processor unmutes the
upstream data output and continues with normal
operation.
7. The muting of the upstream data path by the host
processor has the effect of muting the handset in a
telephone application so the user cannot hear the
acknowledgement tone and CID data being sent.
8. The CALD bit can be set to 0 to reenable the
automatic calibration when going off-hook.
Due to the nature of the low-power ADC, the data
presented on SDO could have up to a 10% dc offset.
The caller ID decoder must use either a high-pass or a
band-pass filter to accurately retrieve the caller ID data.

4.19. Overload Protection
The Si3016 can detect if an overload condition capable
of damaging the DAA circuit is present. The DAA may
be damaged if excessive line voltage or loop current is
sustained.
The overload protection circuit utilizes the LVCS bits to
determine an excessive line current or voltage per the
When off-hook, if OPE is set and LVCS = 11111, the dc
termination is disabled (800
Ω presented to the line), the
hookswitch current is reduced, and the OPD bit is set.
Note: If the OPE bit is enabled before going off-hook, the
overload protection circuit can be activated by the line
transients produced by going off-hook. To avoid this,
the OPE bit should be 0 prior to going off-hook. This bit
can then be set ~25 ms after going off-hook to enable
the overload protection feature.
4.20. Analog Output
The integrated system-side module that the Si3016 is
connected to supports an analog output (AOUT) for
driving the call progress speaker found with most of
today’s modems. AOUT is an analog signal that is
comprised of a mix of the transmit and receive signals.
Notes:
1. The off-hook counter is used to prevent transmission or reception of data for 1548/Fs to allow time for the line voltage to
settle. If the CALD bit is 0, an automatic calibration will also be performed during this time.
2. The caller alert signal (CAS) tone is transmitted from the CO, which signals an incoming call.
3. When the MODE bit is set while the device is off-hook, the device is forced on-hook. This is done to read the line voltage
in the LVCS bits to detect parallel handsets. In this mode, no data is transmitted on the SDO pin.
4. When the device returns off-hook after being forced on-hook using the MODE bit, the normal off-hook counter is
disabled. Additionally, if the CALD bit is set, the automatic calibration will not be performed. The fast DCT mode must be
manually enabled for at least 30 ms in order to properly settle the line voltage. This is done by setting the ONHM bit after
disabling the MODE bit.
5. After allowing the line voltage to settle in fast DCT mode, normal off-hook mode should be entered by disabling the
ONHM bit. If CID data reception is desired, the appropriate signal should be sent to the CO at this time.
