Modem On/Off Control
The modem on/off input line (HOSTPWR_ON) is an active high input
signal and is fitted with a 33Ω series resistor and clamp diode to the
internal supply line for input protection. Internally it is passively pulled
low (after the series resistor) via a 56kΩ pull-down resistor to ground
and is asserted with an actively driven high signal. To turn the modem
off it must be actively pulled low to ground. The electrical interface
specification and equivalent circuit is as follows:
