Modem Reset Input
The reset input line (HCRESET) is an active low input signal (TTL
compatible) and is fitted with a 6.8kΩ series resistor for input
protection. Internally it is passively pulled high (after the series
resistor) to the supply rail (3V) and is asserted with an actively driven
low signal to ground. The electrical interface specification and
equivalent circuit is as follows:
