Abstract
A programming module for programming a plurality of unprogrammed subscriber sets with data signals stored in a single programmed subscriber set. The module receives data signals from the programmed set, and stores them in an electrically erasable read only memory. The module is then disconnected from the set and reconnected to successive ones of the unprogrammed sets, for loading the data signals therein, such that the one or more unprogrammed sets become programmed in accordance with the data signals received from the programmed set. The data signals are typically comprised of special feature access codes and speed call numbers.
