Programmable subscriber set
First Claim
1. A subscriber set for connection via tip and ring leads to a communication system for implementing a plurality of special features, comprised of:
- (a) means for bidirectionally translating audio signals between the set and said communications system,(b) a plurality of soft keys associated with predetermined ones of said special features, wherein said predetermined special features are independent of the number of said keys, each key being associated with different ones of said plurality of special features at different times during the course of a telephone call with said subscriber set,(c) means for programming said set to generate and transmit to said communication system predetermined special feature access code signals in response to depression of a predetermined one or a sequence of said soft keys in order to implement said predetermined special features, and(d) visual display means for generating prompt signals associated with said predetermined one or sequence of said soft keys for prompting the depression of said predetermined one or sequence of soft keys in order to generate said special feature access code signals.

Abstract
A subscriber set for connection via tip and ring leads to a remote communication system such as a PABX or centrex. The remote communication system is capable of implementing a plurality of special features such as hold, call transfer, call forward, etc. The set is comprised of a microprocessor and electronic telephone circuit connected to a plurality of programmable function keys, for generating one or more centrex or PBX special feature access code signals in response to depression of predetermined ones of the keys. An LCD display is connected to the microprocessor for generating prompt signals for indicating implementation of predetermined ones of the special features associated with depression of corresponding ones of the keys. The special feature access code signals are programmed into the set such that the set may be used with a variety of PABX and centrex facilities in lieu of expensive proprietary subscriber sets or awkward and difficult to use standard type 2500 sets.
