Abstract:
A method of falling back from a high speed mode to a lower speed mode in a modem using a startup procedure having multiple phases for startup in the high speed mode and corresponding multiple phases for startup in the low speed mode, the method comprising the steps of:performing a first phase of the multiple phases for startup in the high speed mode; determining, responsive to the performing step, if a connection to the modem is capable of supporting high speed mode operation; performing a second phase of the multiple phases for startup in the high speed mode if the connection is capable of supporting high speed mode operation; and performing a phase of the multiple phases for startup in the low speed mode if the connection is incapable of supporting high speed mode operation, wherein the phase of the multiple phases for startup in the low speed mode corresponds to the second phase of the multiple phases for startup in the high speed mode.
