|The DualSpan™ Series of digital voice and network interface boards provide two E-1 or T-1 ISDN Primary Rate Interface lines of service termination and call processing for 30 or 60 voice channels (E-1 boards) or 24 or 48 channels (T-1 boards) in a single PC slot. Functionally, the DualSpan boards are equivalent to two single-span boards, such as the D/300SC-E1 or D/240SC-T1, combined into one single-slot ISA board. A unique multiprocessor architecture comprising digital signal processors (DSPs) and general purpose microprocessors handles all telephony signaling and performs all DTMF, MF, and audio/voice signal processing tasks. The DualSpan boards, as members of the DIALOG/HD™ High Density Voice and Switching Products Series, are based upon Signal Computing System Architecture™ (SCSA™). SCSA provides an open architecture that enables developers to use products from multiple vendors to build a unified computer telephony solution. SCSA provides features such as distributed switching, logical addressing, and location independent resource management.
