Abstract
A modem that handles interruptions caused by call waiting signals is described. When the modem detects a call waiting signal, the modem alerts the user to the presence of the call waiting signal, and permits the user to answer the incoming call by taking a local phone that is connected to the modem off-hook. When the local phone is taken off-hook, the modem automatically generates a hook-flash signal to switch to the incoming call. When the user places the local phone back on-hook, the modem generates another hook-flash signal to resume (if possible) the modem connection. Additionally, the modem prevents a 'fallback', in which the modem switches from its current protocol to a lower-speed protocol, during a 'retrain' process caused by a call waiting event.
