NEW PRODUCT NEWSedited by Rick Prescott

New ProductsAutomatic Ringdown Unit

The QuickLink private wire two-way automatic ringdown unit provides instant off-hook access between two telsets or equivalents (fax, modem) in a tiny package at a lower cost than any existing method. The new "hockey puck" design replaces larger, more expensive, chassis/case or discrete component solutions.

Powered from either a 12-VAC wall adapter or 24- to 48-VDC supply, the device generates its own battery feed and ringing supply with selectable cadences. Standard models with differing feature sets cover most cost and technical requirements; customized specifications are economic in small production runs.

Monolithically encapsulated units are stackable to conserve space or may be PCB-mounted as a single component in OEM applications. In stand-alone use, it becomes a traditional "hotline" device.

Size is only 5/8ý ý 4 ýý ý 2 ýý, six oz. Pricing starts at around about $50 in OEM quantities.
