ABSTRACT:
The present invention provides a user installable option module which contains upgrade circuitry to add additional functions to a basic telephone. This generic upgrade module is capable of containing different sets of electronic circuitry which perform different functions and have different applications. The option module is user installable, and requires neither shipping the original unit to repair or upgrade, nor does it require trained service personnel to visit the customer site to perform the installation. The user installed option is installed in the base of a basic telephone. After installation, the option module appears to be an integral part of the basic telephone and is not readily visible to the user. The basic telephone also retains its original footprint. The option module is secured to the basic telephone in such a manner that prevents the option module from being damaged when subjected to significant forces.
