2.3.2
In the off-hook state, the feed current must usually be kept at a constant value
independent of load (see
information to the SLICOFI-2x via the IT pin (input pin for DC control). The SLICOFI-2x
compares the actual current with the programmed value and adjusts the SLIC drivers as
necessary.
to 50 mA depending on the particular SLIC version in use.

Depending on the load, the operating point is determined by the voltage
between the Tip and Ring pins.
The operating point is calculated from:
