Abstract

A communication device (100) includes three levels and at least one feature and at least one protocol for communicating with other communication devices. The three levels are high level or user ergonomics (302), common level or feature/protocol (310), and low level or hardware platform (318). The feature/protocol level (310) is adapted for controlling the at least one feature and the at least one protocol. The user ergonomics (302) includes a first interface (304) coupled to the feature/protocol level (310) for allowing the user ergonomics level (302) to change without affecting the feature/protocol level (310). The, hardware platform (318) includes a second interface coupled to the feature/protocol level (310) for allowing the hardware platform (318) to change without affecting the feature/protocol level (310) or the user ergonomics level (302).
