The N-8410MS master station connects directly to the N-8400RS Sub Station Interface unit and provides master station functions except for those that rely on the use of an LCD screen (see N-8600MS and N-8000MS) Hands-free or handset communication, and full duplex calls to full duplex stations or masters, is supported.
