Voltage reserve of the SLIC output buffers: this voltage drop depends on the output
current through the Tip and Ring pins. For a standard output current of 25 mA, this
voltage reserve is a few volts.
Voltage reserve for AC speech signals: max. signal amplitude (example 2 V)
Voltage reserve for AC metering pulses: The TTX signal amplitude
