TELLABS TO INTRODUCE ITS HIGH-BIT-RATE DIGITAL SUBSCRIBER LINE PRODUCT
 AND OTHER VOICE AND DATA COMMUNICATIONS PRODUCTS AT COMNET '92
 LISLE, Ill., Dec. 16 /PRNewswire/ -- Tellabs, Inc. (NASDAQ: TLAB) said today it will unveil its high-bit-rate digital subscriber line (HDSL) transmission product and other voice and data communications equipment at Communication Networks (ComNet) '92 Conference and Exposition.
 ComNet will be held Jan. 28-30, 1992 at the Washington Convention Center in Washington, D.C.
 The HDSL system developed by Tellabs will provide North American telephone companies and other telecommunications service providers an alternative means of deploying T1 lines.
 "For at least the remainder of this decade, HDSL technology will play an important role in the infrastructure of the public telephone network," said Jon C. Grimes, vice president and general manager of the Network Products Division at Tellabs. "We believe that even as the network evolves toward fiber-optic transmission, telephone companies will use HDSL technology to optimize the return on investment from their large embedded bases of copper facilities and to stimulate deployment of new services."
 PROVIDING TELCOS AND OTHERS WITH ADDED SERVICES/RELIABILITY
 Grimes said Tellabs' HDSL system will provide several advantages for telephone companies and private local area network service providers. Those advantages are simplified installation, reduced installation and maintenance costs, greater service reliability, and the ability to easily provision new service offerings. Grimes also noted that the HDSL system will make it possible for telephone companies to reduce their installation time for T1 services down from four weeks to several days.
 Private local area networks will also benefit from HDSL transmission technology. For example, Fortune 500 companies that have invested in copper facilities in a campus environment can improve their voice, data and video transmission capabilities by using HDSL technology.
 Tellabs said it also will introduce numerous other products and product enhancements at ComNet '92. The following is a brief description of those products and systems.
 TELEMARK(R) Network Management System
 The TELEMARK system, Tellabs' first stand-alone software product, is a high-end network management and control system designed for both telephone service providers and end-users.
 The TELEMARK system is designed to support Tellabs' TITAN(R) 5300 series digital cross-connect systems and CROSSNET(R) digital multiplexers. A network operator using the TELEMARK product is provided with a single point of monitoring and control through circuit management and recovery network reports, surveillance and graphics. The capabilities of TELEMARK Release 2.2 also include the management of voice and data connections between Tellabs' T1 multiplexers.
 CROSSNET(R) 240 Network Terminating Unit
 The CROSSNET 240 Network Terminal Unit (NTU) is a digital transmission system that uses 2B1Q line coding to transmit full duplex high-speed (up to 128 kbps) data over a single non-loaded pair of wires. The 2B1Q algorithm used in the 240 NTU enables data transmission on local loops containing multiple bridge taps and mixed cable gauges. The 240 NTU can operate in a stand alone back-to-back application or in conjunction with the Tellabs' CROSSNET 44X multiplexer when equipped with the 4341E interface card.
 DS3 Interface for TITAN(R) 5300 Series
 The DS3 interface equipment shelf provides a bidirectional interface between the network T3 medium and Tellabs' TITAN 532 primary rate cross- connect system and forms a DS3/DS1/DS0 digital cross-connect system. T1s embedded within DS3 can either be routed through the TITAN 532 as intact constituent DS1s or groomed on a DS0 basis. Support for this integrated DS3 interface eliminates the need for separate M13 muldems and DSX panels as well as the associated T1 interfaces on the digital cross-connect.
 Enhanced Processor for TITAN(R) 532
 A state-of-the-art processor platform has been developed for the TITAN 532 digital cross-connect system. The enhanced processor will provide four times more power and up to eight times more memory than the present platform. Network planners will now have the ability to upgrade their feature set without removing the feature package module from their existing TITAN 532 system.
 341 Xplexer(tm) Statistical Multiplexer
 The Tellabs' 341 Xplexer is a high-speed intelligent virtual-circuit packet switch that can interface as many as 35 composite data links. The product is part of Tellabs' 300 Series networking product family and is compatible with all 300 Series products.
