    CONFIGURATION PROM INSTALLATION CONFIGURATION PROM The TRP 9250 series Configuration PROM contains frequencies, frequency bands and system configuration parameters for customizing the equipment. Legal frequencies with corresponding legal mode and frequency bands are programmed in the PROM address area from 256d/0100h to 7167d/1BFFh. The PROM area is divided into three sub-areas, each with a specific frequency information and representation.
