ADC, OSI Announce Joint Development of Element Manager for HFC Networks.

MINNEAPOLIS--(BUSINESS WIRE)--Aug. 21, 1995--ADC Telecommunications, Inc., and Objective Systems Integrators (OSI) announced today that they have signed an agreement to jointly develop a set of element manager systems for ADC's Homeworx(TM) hybrid fiber coax (HFC) access platform. Under the proposed agreement, ADC and OSI will jointly market the NetExpert(TM)-based OSWorx(TM) element manager systems to domestic and international network service providers. Trials will begin in September 1995, with commercial availability scheduled for the third quarter of 1995.

The element manager leverages a number of common interface standards, such as the Transactional Language 1 (TL1) standard and the CMISE standard, and will provide a total Telecommunications Management Network (TMN) system-based solution for managing voice, video and data services.

The element manager will be based on OSI's NetExpert technology, which will ensure a robust and complete software suite with a full graphical user interface, network topology mapping, client-server architecture and object-oriented software. The NetExpert-based OSWorx element manager will feature open interfaces, enabling it to interoperate with OSI's higher-level network management systems, as well as other operations support systems. The element manager will be compliant with Bellcore standard TR-008 with a TL1 interface as well as Bellcore TR-303 standard with a CMISE interface.

Tim Sebring, OSI's director of sales and marketing for the communications industry in the Americas, stated, "Partnering with ADC will create additional value and options for both telephone companies and cable TV operators worldwide. This solution will allow OSI to provide leading-edge, fast-to-market management systems for HFC networks worldwide."

Jim Granger, vice president and general manager of ADC's access platform systems division, added, "The combined resources and expertise of OSI and ADC will result in extremely robust and cost-effective network management solutions for service providers as they face increasing pressure to respond quickly to the needs of their customers for new services."

The Element Management Layer (EML) in an HFC network provides a primary interface between the Homeworx system components and existing customer operations environments. The OSWorx element manager system will provide a number of critical functions including configuration management, such as inventory and provisioning; fault management, including testing, alarming and alarm correlation; performance management; and security management.

The Homeworx platform transports both digital and analog broadband signals, as well as narrowband telephony and data services over a hybrid fiber/coax architecture to residential and small business customers. By installing the Homeworx HFC access platform, a service provider is well positioned to add telephony and data services in the future. The platform is being deployed by or has been in field trials with Ameritech, Cable Bahamas, Comcast, Cox Cable, Nynex, Optus Vision, Rochester Telephone, SNET and Time Warner.

OSI is the leading provider of communications-based operations support systems, products, and services including network management, trouble management, performance management, service provisioning, configuration management and data collection. Headquartered in Folsom, California, OSI successfully supports worldwide installations of NetExpert. OSI's growing base in the commercial marketplace includes finance, transportation, utilities, manufacturing and government users.
