First Claim
1. A secured communication system comprising a first apparatus and a second apparatus whereinsaid first apparatus comprisinga first host unit having a data receiver for receiving voice data and a transmitter for communicating with said second apparatus;
- anda first card unit detachably coupling to said first host unit, wherein said first host unit transmits said voice data to said first card unit for processing, wherein said first card unit performs data processing on the voice data received from said first host unit, and wherein said processed data is returned to said first host unit from said first card unit,said second apparatus comprisinga second host unit comprising a receiver for communicating with said first apparatus, wherein the processed data is received from said first host unit to said second host unit; and
a second card unit detachably coupling to said second host unit, wherein said second host unit transmits said processed data received from said first host unit to said second card unit for processing, wherein said second card unit reconstructs said voice data from said processed data, and wherein the reconstructed voice data is returned to said second host unit from said second card unit.

Abstract
The present invention provides a detachable add-on card unit to a host system that combines mass storage capability and a processor on the same card. The card can receive data from the host, process the data, and store it in processed form, as well as the reverse process of retrieving stored data, processing it, and supplying it to the host. The non-volatile mass storage memory may contain program storage as well as card system data and user data. The end user of the card can program applications into the program storage. The combination of mass storage and a processor also adds to the capabilities of the on-card processor, allowing the card to store and execute programs. The present invention is able to provide a programmable add-on card unit to a host system. A number of applications can be stored in the card'"'"'s mass storage and loaded as needed by the on-card micro-controller.
