A time attendance system, including a time attendance clock, designed to be used in harsh conditions, such as outdoor job sites. A portable touch button, including a passively readable code, is brought into contact with the time attendance clock so as to create a time attendance record stored in the clock. Visual indicators and audible notification alert the employee of the acceptance of the act. Periodically, the time attendance records are retrieved from the time attendance clock, such as by using a hand-held electronic device which communicates in a wireless manner with the time attendance clock.

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.
