A telephone set is disclosed which includes an adjunct interface module within the telephone set stand of the telephone set. This adjunct interface module converts the telephone set interface, which connects the telephone set to a premise switching system, to a different interface that is used by adjunct telephone equipment associated with the telephone set. Typically, the telephone set interface is a non-standard, or proprietary, interface, while the adjunct interface is the more common tip-ring interface.
