FlashPoll is designed to optimize communication links
where high speed
 or unlimited number of drops
 is necessary.

The TEL/DSP9612 modem "FlashPoll" is designed to optimize communication links where high speed or unlimited number of drops is necessary. Ideal for SCADA, traffic and the oil industries, the 9612 modem is a cost-effective, full-featured fast poll, leased line modem with the fastest training time in the industry: 23msec RTS/CTS delay.

The DSP9612 modem FIashPoll operates at 9600, 4800 and 1,200bps (202T modulation)  bps over 2- or 4-wire leased or metallic lines and is temperature hardened for industrial, substation or traffic applications. When used with terminal polled devices, an unlimited number of drops is possible.

The earlier Telenetics DSP9600 Flash Poll (DSP9600FP) modem was a 9600/4800 bps stand-alone modem designed for 4-wire full-duplex or 2-wire half-duplex operation over voice-band leased line. The DSP9600FP modem utilized digital-signal processing (DSP) technology to achieve high performance. The DSP9600FP modem also employed Telenetics' proprietary modulation and encoding scheme to achieve fast modem training time. These advantages made the DSP9600FP modem the most technologically advanced product on the market a few years ago.  It has only been surpassed by the new DSP9612 series.  These modems are especially suited for multi-point communication systems that require fast response time, short training time and low throughput delay.
