ABSTRACT:
An attachable module for expanding or enhancing the functionality of a desktop telephone terminal is disclosed. The module comprises a body on which are mounted a display, a plurality of function keys and a scroll key, all of which are connected to electronic circuitry housed within the body. An appendage projects from the body and comprises a pair of upwardly extending toothed protrusions and an electrical connector. The protrusions and electrical connector are intended to mate respectively with a pair of complementary cavities and a complementary electrical connector located in the underside of the terminal. The appendage is comprised of several sections of varying dimensions, yielding a structure that, in combination with the body of the module, provides a strong and stable mechanical connection when the module attached to the terminal. Operationally, the module can increase the size of a "speed call" list, increase the number of external lines available at the touch of a button and increase the number of other functions accessible by pressing a single function key. The scroll key allows the user to browse through pages of functions when their number exceeds the number of function keys on the module.
