Details

Commetrex Corporation30 is a fax protocol state machine portable across a number of operating systems and hardware platforms. In order to achieve portability the machine isolates system dependencies to "adaptation" packages. The process of porting T.30, then, requires the rewrite of the adaptation packages, not T.30.

This design partitioning has resulted in the following major components:

  • T.30 Core consisting of the T.30 state machine and HDLC support routines.
  • Event Preprocessor converts system events into T.30 Core events.
  • Hardware Adaptation consisting of routines for interfacing with the modems.
  • Timer Package provides timer service to the T.30 Core.
  • Image Data Service handles image data and conversions on-line.
  • Image I/O Service handles physical I/O of the image data.
  • API Package provides an interface for the controlling application.
  • Buffer Management Package manages a pool of image-data buffers.
  • Parameter Manager provides access to system parameters by name.
