          Based on Paradyne's award-winning COMSPHERE 3800 Series architecture, the software-defined flexibility of the 3920Plus allows you to change, upgrade or enhance the unit's functionality via downloads over the public switched or leased-line network.

          Ordering Information

          The COMSPHERE 3920Plus delivers unsurpassed reliability with its full-featured standalone design for either point-to-point or mulitpoint applications. The four-port Time Division Multiplexer (TDM) model maximizes your applications' network efficiency and cost effectiveness by reducing the potential for additional lines and/or equipment. The 3920Plus can be configured for two or four wire analog leased-line networks with dial restore via two-wire dial or two-wire leased line. Should the line quality deteriorate, it can automatically downshift to lower speeds, attempting to preserve the link. If the modem is not able to operate at the minimal selected rate, it will initiate non-disruptive dial restore.

          With front panel controls, you have access to local and remote modems for configuration, control and status. The 3920Plus supports diagnostic tail circuits and delivers Trellis multipoint turnaround times as low as 10ms. It also supports a number of other leased-line and dial modulations between 300 and 33,600bps.
