ADTRAN's New Express Products Combine Data And Voice Over Frame Relay Or ISDN With Optional Disaster Recovery

ADTRAN, Inc. introduced its new Express 5210 Frame Relay access device and Express 4110 ISDN router. Both products add new functionality to ADTRAN's comprehensive Express series -- a family of remote site termination products for dedicated, switched, and packet-based network services.

The Express 5210, a member of the Express 5200 series, supports voice, data, and disaster recovery on Frame Relay networks. By using the 5210, network managers can consolidate voice onto already subscribed Frame Relay data circuits, eliminating unnecessary voice circuits. When desirable, network managers can implement disaster recovery over ISDN, V.34 or Switched 56 networks using an easy-to-install expansion card. The 5210 also includes a LAN interface, eliminating the need for an external router.

The Express 4110, a member of the 4100(TM) series, is a low-cost ISDN router designed for SOHO applications requiring Internet access. The Express 4110 simultaneously translates multiple LAN addresses into a single dynamic IP address using Network Address Translation (NAT). The network manager saves money by supporting multiple Internet users on a single IP address.

"These new Express products, when paired with our ATLAS host site product, offer customers a single vendor solution to all their network access needs, " comments Danny Windham, vice president of CPE marketing. "ADTRAN is one of the few vendors that provides a truly complete wide area access solution for Frame Relay and ISDN, including disaster recovery. Our goal is to make access over any wide-area network alternative as painless and hassle-free as possible for each customer."

ADTRAN recently regrouped its full line of packet-based and switched termination products into three Express product series -- Express 3000 ISDN modems, Express 4000 ISDN routers, and Express 5000 Frame Relay access devices for data and voice. Future products developed for Frame Relay and ISDN access will be positioned in these families. ADTRAN also offers the IQ family, a full line of intelligent remote site devices for Frame Relay performance monitoring.

The Express 5210 lists for $1,295 and will be available in March 1999. The Express 4110 lists for $595 and will be available in February 1999.
