The ProSLIC is designed to create a fully-balanced
ringing waveform, meaning that the TIP and RING
common mode voltage, (VTIP + VRING)/2, is fixed. This
voltage is referred to as VCM_RING and is automatically
set to the following:
VCMR is an indirect register, which provides the
headroom by the ringing waveform with respect to the
VBATH rail. The value is set as a 4-bit setting in indirect
Register 27
with
an
LSB
voltage
of
1.5 V/LSB.
Register 27 should be set with the calculated VOVR to
provide voltage headroom during ringing.
The ProSLIC has a mode to briefly increase the
maximum differential current limit between the voltage
transition of TIP and RING from ringing to a dc linefeed
state. This mode is enabled by setting ILIMEN =1 (direct
Register 108, bit 7).
2.4.6. Ring Trip Detection
A ring trip event signals that the terminal equipment has
gone off-hook during the Ringing state. The ProSLIC
performs ring trip detection digitally using its on-chip A/
D
converter.
The
functional
blocks
required
to
implement ring trip detection are shown in Figure 23.
The primary input to the system is the Loop Current
Sense (LCS) value provided by the current monitoring
circuitry and reported in direct Register 79. LCS data is
processed by the input signal processor when the
ProSLIC is in the Ringing state as indicated by the
Linefeed Shadow register (direct Register 64). The data
then feeds into a programmable digital low pass filter,
which removes unwanted ac signal components before
threshold detection.
The output of the low-pass filter is compared to a
programmable threshold, RPTP (indirect Register 16).
The threshold comparator output feeds a programmable
debouncing filter. The output of the debouncing filter
remains in its present state unless the input remains in
the opposite state for the entire period of time
programmed
by
the
ring
trip
debounce
interval,
RTDI[6:0] (direct Register 70). If the debounce interval
has been satisfied, the RTP bit of direct Register 68 will
be set to indicate that a valid ring trip has occurred. A
ring trip interrupt is generated if enabled by the RTIE bit
(direct Register 22). Table 30 lists the registers that
must be written or monitored to correctly detect a ring
trip condition.
The recommended values for RPTP, NRTP, and RTDI
vary according to the programmed ringing frequency.
Register values for various ringing frequencies are
given in Table 31.
