* Auxiliary port function: In download mode, the auxiliary port function for all profiles operates as a true Auxiliary
port. This means that when the power comes back on, and if the Aux Port is in-use, that line will show on the
system telephones as being in-use (LCD indicator lit) until the Aux Call is cleared.
In dipswitch mode, the North American and Taiwan auxiliary ports also act as true auxiliary ports.
However, the UK and Australia profile auxiliary port function is different. In these profiles, when the power is
restored, the Aux Port call is terminated and the line is available to system telephones.
