TN772
The TN772 selects the active Switch Processing Element (SPE) (control complex) in high reliability and critical reliability R6 and some earlier systems. The TN772 also coordinates the interchange of SPEs.
The TN772 controls the memory shadowing function with the duplication option, terminates the environmental sensors, and controls the integrated battery supply and charging circuits. The TN772 is also responsible for selecting the active SPE, selecting the active tone-clock circuit pack, and providing an administration terminal interface in place of the processor. A second TN772 circuit pack resides in the duplicated control carrier/cabinet and requires a cable connection to the Duplication Interface circuit pack in the basic control carrier/cabinet.
