Dialogic D/80SC-4LS

• High-density analog interface voice processing platform enables system integrators and developers to lower costs by incorporating more ports per chassis, by using less expensive desktop-style machines, and by easing configuration/installation effort

• Four independent loop start telephone interfaces combined with eight channels of voice processing in one ISA slot, provide effective solutions for building high-density applications

• Create more cost-effective switching solutions via access to the SCbus with its 1,024 time slot capability; SCxbus interbox communications provides the capability to build higher density systems and large, multinode systems

• Caller ID capability for "screen pop" applications (supports Bellcore CLASS* Protocols)

• Configure multiple Dialogic boards in a single PC (ISA bus) for easy and cost-effective system expansion on the best computing platform that best fits your needs

The Dialogic D/80SC-4LS board provides 8 channels of call processing and 4 channeks of loop start interfaces in a single PC slot. A unique dual-processor architecture composed of DSPs and a general-purpose microprocessor handles all telephony signaling and performs all DTMF (touch tone) and audio/voice signal processing tasks. Downloaded firmware algorithms provide variable voice coding at 24 and 32 Kb/s Adaptive Differential Pulse Code Modulation (ADPCM), and 48 and 64 Kb/s Pulse Code Modulation (PCM) µ-law or A-law. Sampling rates and coding methods are selectable on a channel-by-channel basis. Applications can dynamically switch sampling rate and coding method to optimize data storage or voice quality as the need arises. Firmware also provides reliable DTMF detection, DTMF cut-through, and talk off/play off suppression over a wide variety of telephone line conditions.
