Abstract

By using simple means, a telecommunications terminal can be expanded to a large number of functions. The telecommunications terminal is composed of a digital signal processor (DSP), an interface (LS, V.24, PCMCIA-S) for the input of software, and means to start the input and execute the software. The software for executing basic functions is fixed and software for executing special functions can be called up and loaded via the interface (LS, V.24, PCMCIA-S).
