ISDN PRI Dynamic Switching
Functioning as an intelligent and dynamic PRI channel bank, an ATLAS Integrated Access Device (IAD) performs the ISDN-to-T1 or analog conversions necessary to support many devices over a single PRI circuit. Using an embedded switchboard and dial plan, ATLAS dynamically routes three- to ten-digit voice calls to service providers on a call-by-call, least-cost routing basis. ATLAS also converts PRI calling/called party numbers to T1 Feature Group D ANI/DNIS format, which eliminates the expense of upgrading an existing PBX to take advantage of attractive PRI tariffs and services. Total Access IADs can be paired with ATLAS for applications that need higher levels of oversubscription.
