3.3.2. Linefeed Operation States
The linefeed interface includes eight different operating
states as shown in Table 18. 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 excess power
consumption is detected in the Si3200/2. See "3.8.
Power Monitoring and Power Fault Detection" on page
37 for more details. The register and RAM locations
used for programming the linefeed parameters are
provided in Table 19. See “3.7. Loop Voltage and
Current Monitoring” and "3.8. Power Monitoring and
Power Fault Detection" on page 37, and "3.8.5. Power
Dissipation Considerations" on page 40 for detailed
descriptions and register/RAM locations for these
functions.
Table 18. Linefeed States
Open (LF[2:0]
= 000).
The Si3200/2 output is high-impedance. This mode can be used in the presence of line fault conditions and to
generate open-switch intervals (OSIs). The device can also automatically enter the open state if excess power
consumption is detected in the Si3200/2 or in the discrete bipolar transistors.
Forward Active (LF[2:0]
= 001).
Linefeed is active, but audio paths are powered down until an off-hook condition is detected. The Si3220 and
Si3225 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 (Si3220) or switches in a centralized ringing
generator by driving an external relay (Si3225).
Reverse Active (LF[2:0]
= 101).
Linefeed circuitry is active, but audio paths are powered down until an off-hook condition is detected. The
Si3220 and Si3225 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.
