ABSTRACT:
A method which, in response to an alerting signal from a source, manages a data transfer from the source, via a communications link, to at least two terminals coupled with the communications link. The method (a) dynamically designates one of the at least two terminals as a token terminal, (b) generates an acknowledgment signal with the token terminal, and (c) terminates the communications link during the data transfer with the token terminal. The dynamic designation of the token terminal is performed by (a) assigning a time delay for each of the terminals, and (b) determining, with each of the terminals, after the assigned time delay, whether the terminal will accept the data transfer from the source based on a condition of the communications link.
