1. An optimizing system for a telecommunications system that includesa host unit which exchanges data streams with a peripheral device, said data streams being routed between said host unit and said peripheral device by a signal routing unit,said peripheral device having an addressable buffer whose information contents are modifiable in response to data streams from said host unit,said buffer contents including data characters and further including control codes,said optimizing system comprising:

  • an optimizer connected to control said signal routing unit and programmedto read the information content of a data stream from the host unit prior to the routing of the data stream to the peripheral device;

    to generate an updated-state image representing the information contents of the peripheral device buffer that would be expected to exist after processing by the peripheral device of said data stream;

    to generate a data stream representing any differences in data characters, as well as any differences in control codes, between said updated-state image and a present-state image representing the information available to the optimizer about the present information contents of the peripheral device buffer; and

    to cause said signal routing unit to route the data stream so generated to the peripheral device in lieu of the data stream from the host unit.
