The Sinus 622 represents T-Com's new, entry-level segment of cordless ISDN phones. Plain, cool elegance dominates the esthetics of this product line. The bold geometric contours convey an impression of lightness and precision. The design avoids fashionable elements to enhance the longevity of the product look. An important part of the overall key design is the product's central, circular keypad. This keypad supports all the basic functions and can be operated with a single finger. A new, interactive design allows for easy and intuitive use of all ISDN network features. The cordless Sinus 622 can also be used in a table unit with integrated DECT base station (Sinus P/PA 622).
