The Match product provided automated systems for telephone companies in Operations, administration and management (OA&M) to migrate telephone services delivered by existings analogue AT&T 1AESS switches to newer digital switches, such as Northern Telecom's DMS-100 or AT&T's 5ESS switches. The MATCH was composed of three main system components: Decoding, Matching, and Provisioning. The Decoding module would decode core memory dumps from the AT&T 1AESS, 5AESS, Nortel DMS-100, and operating databases including COSMOS and TIRKS. Network inventory, services, and related constructs would be stored in a proprietary MATCH universal database management system, which was configurable based on job and customer preferences. The Matching module would compare two populated databases, being a source and target, and compute the functional transform required to bring the target system in line with the source. The Provisioning model examined the transform function and generated the necessary AT&T 5AESS recent change messages and DMS-100 service updates to reproduce telephony services provided by the old switch on the new switching platform.
