4.3.2. Linefeed Operation States
The linefeed interface includes eight different operating
states as described in Table 12. The Linefeed register
settings (LF[2:0], Linefeed Register) are also listed. The
Open state is the default condition in the absence of any
pre-loaded register settings. The device may also
automatically enter the Open state if any excess power
consumption is detected in the Si3200. See "4.4.3.
Power Monitoring and Power Fault Detection" on page
26 for more details.
The register and RAM locations used for programming
the linefeed parameters are provided in Table 13. Also
see “4.4.2. Loop Voltage and Current Monitoring” and
"4.4.3. Power Monitoring and Power Fault Detection" on
page 26 for more detailed descriptions and register/
RAM locations for these specific functions.
Table 12. Linefeed States
Open (LF[2:0]
=
000).
The Si3200 output is high-impedance. This mode can be used in the presence of line fault conditions and to gen-
erate Open Switch Intervals (OSIs). The device can also automatically enter the Open state if any excess power
consumption is detected in the Si3200.
Forward Active (LF[2:0]
=
001).
Linefeed is active, but audio paths are powered down until an off-hook condition is detected. The Si3232 will
automatically enter a low-power state to reduce power consumption during on-hook standby periods.
Forward On-Hook Transmission (LF[2:0]
=
010).
Provides data transmission during an on-hook loop condition (e.g., transmitting FSK caller ID information
between ringing bursts).
Tip Open (LF[2:0]
=
011).
Sets the portion of the linefeed interface connected to the TIP side of the subscriber loop to high impedance and
provides an active linefeed on the RING side of the loop for ground start operation.
Ringing (LF[2:0]
=
100).
Drives programmable ringing waveforms onto the subscriber loop.
Reverse Active (LF[2:0]
=
101).
Linefeed circuitry is active, but audio paths are powered down until an off-hook condition is detected. The Si3232
will automatically enter a low-power state to reduce power consumption during on-hook standby periods.
Reverse On-Hook Transmission (LF[2:0]
=
110).
Provide data transmission during an on-hook loop condition.
Ring Open (LF[2:0]
=
111).
Sets the portion of the linefeed interface connected to the RING side of the subscriber loop to high impedance
and provides an active linefeed on the TIP side of the loop for ground start operation.
