TIP/RING DC signal generation. The Dual ProSLIC
line feed D/A converter can program a constant
current linefeed from 18–45 mA in 0.87 mA steps
with a ±10% total accuracy. In addition, the open-
circuit TIP/RING voltage can be programmed from 0
to 63 V in 1 V steps. The linefeed circuitry also can
generate a controlled polarity reversal.
Tone generation. The Dual ProSLIC devices can
generate single or dual tones over the entire audio
band, and can direct them into either the transmit or
the receive path depending on the diagnostic
requirements. Ringing signals from 4–100 Hz also
can be generated.
Diagnostics mode ringing generation. The Dual
ProSLIC devices can generate an internal low-level
ringing signal to test for the presence of REN without
causing the terminal equipment to ring audibly. This
ringing signal can be either balance or unbalanced
