A data transmission system for a host computer includes a converter coupled to the host computer and an external data transmission network for converting signals from one form into another, and an isolation circuit for electrically isolating the host computer from the data transmission network. The isolation circuit is placed between the host computer and the converter such that the host computer is electrically isolated from the data transmission network when data transmission is conducted between the host computer and the data transmission network. The isolation circuit digitally isolates the host computer from the external data transmission network such that noise and signal distortion generated by the isolation circuit do not affect the data transmission between the host computer and the data transmission network. The isolation circuit digitally isolates the host computer from the data transmission network such that the isolation circuit can be implemented by opto-couplers and/or transformers and the signal distortion and noise produced by the opto-couplers, transformers, and/or other known means that do not affect the data transmission between the host computer and the external data transmission network.
In a data transmission system for a host computer and having a digital signal processor coupled to the host computer and a converter coupled to the digital signal processor and to an external data transmission network for converting signals from one form into another, and an isolation circuit for electrically isolating the host computer from the external data transmission network, the improvement comprising:
