Telenetics DSP9612RM Modem

Dual Mode: DSP9612RM modem -
9600 Fast Poll / multidrop
multipoint and FSK Bell 202T 0-1800 bps
rack mounted modems for central site applications

The ID96HFP modem now supersedes the DSP9612 FP-LV-RM and modems and is completely compatible. The IG96HFP is ideal for point-to-point and multi-point polling network with the industry's fastest training time.
(This part number change allows us to harmonize the older DSP part number in to our newer DCE IG product line)

Now go supper fast (19.2Kbps) on a Multi-Drop-Point Lease Line -
with wide temperature range and DC power

The Telenetics FlashPoll DSP9612RM modem is a dual mode, full-featured 9600 Fast Poll and Bell 202T leased line modem with the fastest training time in the industry: 23msec RTS/CTS delay. Ideal for utility and industrial automation multi-dropping applications, including SCADA systems, traffic automation and oil & gas automation projects, where an unlimited number of drops is desirable. The DSP9612RM is a rack-mount modem designed for 4-wire, full-duplex or 2-wire, half-duplex operation over a voice-band leased line. The modem design utilizes the latest digital-signal processing (DSP) technology to achieve high performance. In FlashPoll Mode (9600/4800 bps), the DSP9612RM employs Telenetics’ proprietary modulation and encoding scheme to achieve fast modem training time. In Bell 202T Mode, the modem is also backward compatible with Bell 202T (0 – 1800 bps) modems. Ideal for systems where fast response, short training time and low throughput delay is required, FlashPoll is optimized for fast receiver equalizer training and extremely low throughput delay. The dual mode capability allows the DSP9612RM to communicate with existing Bell 202T (0-1800, bps) remote modems, which can then be upgraded at a later date to Telenetics DSP9600FP FlashPoll standalone modems (see separate Data Sheet).
