TxPORT Enters T3 Market With Robust CSU DSU; Newest Digital Offering Extends TxPORT Products From Sub-DDS to T3 Rates.

HUNTSVILLE, Ala.--(BUSINESS WIRE)--Feb. 19, 1996--TxPORT announces their first entry in the high-speed T3 market with the model 3301 CSU/DSU.

Supporting data rates from 3.157 million bits per second to 44.210 million bits per second (the equivalent of 28 T1 lines), the new 3301 includes an industry standard HSSI (high speed serial interface) for video teleconferencing, CAD/CAM, host channel extensions or bridge/router applications.

Incorporating advanced performance monitoring features and powerful diagnostics, the new TxPORT 3301 T3-CSU/DSU allows the user to rapidly isolate unit and/or facility problems. Errored seconds, error free seconds, severely errored seconds and short failure events are continuously monitored and kept in a 24-hour register for local or remote access using an ASCII terminal. The enhanced performance and operational requirements of the 3301 conform to the AT&T 54014 industry standard.

"The addition of the 3301 to our family of high-speed digital transmission products is a good fit for us," said Dave Marvel, vice president of marketing for TxPORT. "The types of customers that are traditionally attracted to our CSU/DSUs and other T1 products are requiring more and more bandwidth for their video teleconferencing and other high-speed applications. T3 is a natural progression for them and we want to be their supplier."

The new 3301 continues the TxPORT tradition of providing users with sophisticated products that are easy to install, easy to use and easy to manage. With any local or remote ASCII compatible terminal, users can quickly and easily perform configuration, set alarm parameters and run local DTE, local line and remote line loopbacks as well as non-intrusive monitoring of network signals. The user interface is a simple command/response language format with intuitive help prompt features.

Users security concerns are addressed with multiple levels of passwords that protect from unauthorized access while providing operational flexibility. Users can be permitted view-only access that prohibit changes to parameters or administrative access to all features and functions.

The TxPORT 3301 includes a 5-year warranty. The unit is available immediately at a suggested list price of $5,995.
