This report (Contract No. H0220073) describes the result of efforts to develop and test a prototype model of a quasi-hardened subsurface communication system. Conceptually, the system provides a one-way digital information link interface between multiple subsurface terminals and a single surface station. Two-way voice communication is also provided. The system is capable of both a direct through- the-earth mode of operation or alternate linking through existing mine telephone hardware circuits.
