Abstract
A digital communication interface for downloading software for upgrading the functionality of a telephone craftsperson's butt-in test set is configured to be powered externally by respectively different voltages ported from the host computer and the test set. Digital communication connectivity for software upgrade signals sourced from the host computer for delivery to the control processor of the test set, and for communication signals sourced from the test set for delivery to the host computer, is effected by a pair of opto-isolators which provide signal integrity isolation between the respectively different parameters of the host computer and the test set.
