With its ability to be adapted for various digital NEC telephone systems (DSX-40, DSX-80, DSX-160 and UX5000), the NEC DTL-8R-1 Cordless DECT phone consists of a base unit and handset. The base unit connects to a digital station port or to a deskphone, in which case it can share the same extension number. A button on the base unit allows you to switch back and forth between the desk phone and the cordless handset.
The maximum range is listed as up to 350 feet although this will depend on the building material in the environment. Range can be extended by adding NEC DSX Cordless DECT repeaters throughout your facility. The DTL-8R-1 operates on the 1.9 GHz DECT frequency so is suitable for use around Wi-Fi installations.
