SureWest Communications Deploys Cisco Optical Solutions to Maintain Reliability for Voice and Data Services.Business Editors/High-Tech Writers ROSEVILLE, Calif.--(BUSINESS WIRE)--Sept. 18, 2002 Integrated communications provider SureWest Communications (Nasdaq:SURW) announced today it has deployed the Cisco ONS ONS Office for National Statistics (UK) ONS One Night Stand ONS Onslaught (Unreal Tournament 2004) ONS Oncology Nursing Society ONS Object Naming Service ONS Offshore Northern Seas 15327 and Cisco ONS 15454 self-healing fiber optic rings as a transport mechanism for providing reliable voice and data services. A self-healing ring A self-healing ring, or SHR, is a common configuration in telecommunications transmission systems. SDH, SONET and WDM systems are often configured in self-healing rings. Description provides for automatic network backup designed for 100% redundancy, so if there is a point of failure, the service continues to function. SureWest's goal is a significant improvement in network flexibility. "Our customers demand and depend on a high degree of system reliability," said Bill DeMuth, Vice President and Chief Technology Officer, SureWest Communications. "We have approximately 25 Cisco nodes for DS-3, OC-3, OC-12, and OC-48, along with 10/100 Megabit and 1 Gigabit Ethernet services, which are integral facets of our service to data and voice customers. The main benefits of the Cisco optical platform are its self-healing optical ring and ability to deliver multiple services." In self-healing SONET (Synchronous Optical NETwork (networking) Synchronous Optical NETwork - (SONET) A broadband networking standard based on point-to-point optical fibre networks. SONET will provide a high-bandwidth "pipe" to support ATM-based services. ) ring architecture two fiber cables are deployed in a ring. The bi-directional (data traffic can move in either direction) cables connect to separate terminals at each node. So, if a ring is severed in one place, the data reverses direction meaning there is no interruption of data or voice transmission. "Deployment of the Cisco optical platform has resulted in efficiencies for SureWest," continued DeMuth. "The ability to deliver both TDM (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. and Ethernet services on a single platform allows quick service turn-up and provides both TDM and Ethernet customers with the benefits that SONET self-healing rings provide." "SureWest is using Cisco optical solutions to achieve increased efficiency and reliability -- benefits service providers require to maintain customer loyalty," said Rob Koslowsky, Director of Marketing at Cisco. "Both SureWest and its customers can benefit from our innovative optical solutions." "The self-healing rings create the type of reliability that customers such as major financial institutions demand," added DeMuth. "Even in the case of a backbone fiber being cut, the customer would not see any service interruption. Using these self-healing rings improves a network's survivability sur·viv·a·ble adj. 1. Capable of surviving: survivable organisms in a hostile environment. 2. That can be survived: a survivable, but very serious, illness. and availability while providing operational efficiencies." SureWest is utilizing the Cisco ONS 15454 at remote sites to increase bandwidth rather than deploying more fiber. In addition, the Cisco ONS 15327 has been deployed at several large customer sites to provide robust voice and data services. About SureWest Communications With nearly 90 years in Northern California, SureWest Communications and its family of companies represent an integrated network of highly reliable advanced communications products and services with the highest standards of customer care. Founded as Roseville Telephone Company, the company has expanded to provide digital cable TV, fiber optics fiber optics, transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber , PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995.
