General Systems Group

Description

General Systems Group (GSG), is a systems architecture firm founded in 1975. GSG has far reaching roots in the Software, Personal Computer and Internet (Web) technologies.

This company pioneered the notion of a "virtual disk", that is, the appearance of a telephone as a "hard disk" about 17 years ago (1992). GSG obtained a number of patents covering this early technology. The technology transformed an ISDN (Integrated Services Digital Network) phone into what today we would call an "external disk drive". The ISDN technology offered a transmission speed of two channels at 64 kilobits per second (2x64 kbs), that is, a total of 128 kbs. A puny amount by today wide band standards. However, the software issues involved in transforming the visibility of a phone device into a disk like interface are exactly the same now as what we faced & solved 17 years ago. Therefore, it is quite puzzling that we still do not seem to have phones, smart or otherwise, which can be directly plugged via a cable into a computer USB port and automatically integrated by the Operating System (OS) to look and behave like an external disk drive. For example, Amazon sells a USB connection cable for the Nokia 2760 (the phone we used for our work below). However, it does not provide the relevant software drivers. The difficulties involved are definitely NOT technical.
