Telenetics' new dual-mode 1200/9600bit/s fast poll modem is now available for production for use in industrial and harsh environmental applications.

Scada, traffic and the oil industry are only a few of the markets that this cost effective, point-to-point or point-to-multipoint, modem serves and is best suited for twisted-pair and leased telecomms line applications.

The 23ms RTS/CTS training time allows multidrop fast polling of dedicated line remote terminal units to upgrade their speeds from the historic Bell202T modems at 0-1800bit/s to 9600bit/s.

The 202T mode is switch selectable to 9600bit/s.

A unique feature of auto RTS/CTS allow polling of "dumb" devices without RS232 control signals.

The first model of this series is a stand-alone unit powered by 85 to 265V AC, 50-60Hz power with filtering and 3750V surge protection.

A low-voltage 12/24/48V DC powered model and a card/rack model that fits a Motorola RM16 slot chassis will follow.

All models offer line isolation and are temperature hardened to operate in -40 to +85C.

All options are switch selectable and do not require a computer to program settings.

The model DSP9612FP is based on a digital signal processor and offers polling over voice grade telephone lines at 1200bit/s in the 202T mode and 9600bit/s with a fallback speed of 4800bit/s for lines of lesser quality.

Robert Way, Director of Sales and Marketing for Telenetics Network Products Group said, "This modem is eight times faster that the industry standard 1200bit/s Bell202T.

In fact, it is so fast we refer to it as our Flash Poll model.

And, at a List price of $895 it is an affordable alternative to the 1200bit/s modems that our industry holds as the standard".

Telenetics offers a complete line of fibre-optic, cellular, landline and microwave modems to the industrial, utility, oil and traffic markets.
