Abstract

Apparatus and method for generating user warning signal during data transmission suspension or degradation, that allows an user to identify that parallel operation of plain old telephone system (POTS) and digital data communications equipment is either occurring, or being attempted. More particularly, the user signal warning indicates the impact to the operation of a multiple channel data communications device as a result of the parallel operation with the POTS equipment. A multiple variable signal alerts the user to the parallel operation, the amount of degradation, the elapsed time of the degradation to data communications, and which user site is causing the degradation by the direction of the data traffic being impacted.
