A method and apparatus is provided. The method includes receiving a signal over a connection from a telephonic device, determining if the signal is greater than a first preselected value, and adjusting a transient response time of a host transceiver configured to receive the signal in response to determining that the signal is greater than the first preselected value. The method further includes determining a switch hook state of the telephonic device based on a DC component of the signal. The apparatus includes first logic capable of receiving a signal over a connection from a telephonic device, second logic capable of determining if the signal is greater than a first preselected value, and third logic configured to receive the signal, the third logic being capable of adjusting a transient response of the apparatus configured to receive the signal in response to determining that the signal is greater than the first preselected value. The apparatus further includes fourth logic capable of determining a switch hook state of the telephonic based on a DC component of the signal.
