In high and critical reliability R7 or later si systems, copies contents of memory from the primary Switch Processing Element (SPE) to a standby SPE, so that the latter can take over immediately when the former fails
Two TN792 circuit packs required, one for primary control carrier and one for standby
You can replace TN772 duplication interfaces with Definity TN792 but you must replace them in pairs
