A modular digital telephone system and method featuring a universal telephony shelf adaptable for incremental expansion of legacy telephone switches and as a building block in the construction of new telephony switches. The sequence controller causes the ROM controller initially transfers a Source, a Destination and a Length to the DMA controller, which uses these values to copy the ROM contents into the memory. The deduplication application may comprise, among other elements, a deduplication handler component to receive a deduplication request to perform deduplication operations for a logical container of a storage system.
