This paper reports on El Paso Natural Gas Co. (EPNG), a 22,000-mi pipe line network serving the Southwest and California, which operates an extensive private analog microwave network between the El Paso headquarters, field offices and compressor stations in Texas, New Mexico and Arizona, and delivery points along its routes in several states. A good portion of the analog microwave network has been in service for over 20 years. When the system was installed, data traffic consisted mainly of slow speed telemetry; stations were manned and there were no field computers. In recent years, system reliability requirements have increased as a result of the dramatic changes in the type of transmitted information. With automation of pipe line and compressor station operations, and more SCADA networks being use for pipe line monitoring, data takes up more of the system's channel capacity. Data communications cannot withstand propagation abnormalities in the microwave system as can voice communications.
