Our latest development brings Nortel DMS® switching systems with reliable proven technology one step closer to today’s world of real time data availability.  Our Sierra Real-time AMAStore® Processing Platform (SRAPP) mediation solution consists of a highly reliable, 100% solid state redundant unit designed to replace the legacy magnetic tape units that traditionally connected to the Nortel Digital Matrix Switching Systems.  This modern state of the art system also replaces legacy DMS-10 (DMS10) and DMS-100 (DMS100) Family Billing Media Converters, BMC II, AMATPS, and the Integrated Billing Storage and Retrieval (IBSR) systems.
