Description
The COMSPHERE 3920Plus Series of software definable, high-speed, network-managed, analog private line modems are fully compatible with ITU V.34 data rates up to 33, 600 bps. Based on Paradyne's award-winning COMSPHERE 3800 Series architecture, the software-defined flexibility of the 3920Plus Series allows you to change, upgrade, or enhance both the single-port and four-port families of modems, via downloads over the public switched or leased-line network. The COMSPHERE 3920Plus Series delivers unsurpassed reliability with its full-featured standalone and carrier mount designs for either point-to-point or multipoint applications. The four-port Time Division Multiplexer (TDM) modem family maximizes your applications' network efficiency and cost effectiveness by reducing the potential for additional lines and/or equipment. The single-port modem family is the newest member of the 3920Plus Series. Like the other members of the series, the single-port fully supports ITU V.34 (33, 600 bps); can be network managed by the COMSPHERE 6700 Network Management System; and meets the requirements to support data integrity and speed critical analog applications. The COMSPHERE 3920Plus Series modems can be configured for two- or four-wire analog leased-line networks with dial restoral via two-wire dial or two-wire leased line. Should the line quality deteriorate, the COMSPHERE 3920Plus Series modems (if optioned) will automatically downshift to lower speeds, attempting to preserve the link. If the modems are not able to operate at the minimal selected rate, the modem will initiate non-disruptive dial restoral.
