Abstract

The present invention PCM (phone computing machine) uses general purpose programmable device (101) as its core. Line-end interface (201), includes RJ11 jack (210), DAA (212) and CODEC (214), connects to telephone line. User-end interface (301), in one embodiment includes RJ11 jack (310), SLIC (312) and CODEC (314) connects to user apparatus/networks/systems. The functionality of PCM is defined when a portable data storage device with application software is plugged in the machine'"'"'s external memory interface (401). PCM'"'"'s great flexibility and low cost will open up new frontier in the telephone system. In addition, a general method similar as PCM can be applied to other cost-effective information processing applications between predetermined information sources. Examples are voice application in microphone system, audio/video processing in home entertain systems.

Claims

1. A phone computing machine operating between telephone line and local user apparatus/networks/systems comprising:

(a) a general purpose programmable device,

(b) a line-end interface to connect to telephone line, and

(c) a user-end interface to connect to user apparatus/network/system, and

(d) first means for converting signal on said line-end interface to signal able to be processed by said general purpose programmable device, and

(e) second means for converting signal on said user-end interface to signal able to be processed by said general purpose programmable device, and

(f) in combination, an external memory interface and function loading means for loading an user application program from said external memory interface to said general purpose programmable device,

whereby said general purpose programmable device will run the user application program and thereby giving user the ability to configure said phone computing machine to his own functionality.

2. The phone computing machine of claim 1 wherein said general purpose programmable device is a CPU specialized for digital signal processing with RAM based code/data space.
