SBC LAUNCHES MULTI-SERVICE OPTICAL NETWORKING SOLUTIONS.SBC (1) (SBC Communications Inc., San Antonio, TX, www.sbc.com) A large, national telecommunications company that grew from a multitude of local and regional companies, including Southwestern Bell, Pacific Bell and Nevada Bell, into a single, unified brand by 2002. Communications Inc. (NYSE NYSE
See: New York Stock Exchange :SBC) has launched Multi-Service Optical Networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. solutions that will provide businesses with an efficient and scalable way to connect mainframes, data centers and storage networks within a metropolitan area.
These new offerings, available through SBC's subsidiaries' -- SBC Southwestern Bell, SBC Ameritech, SBC Pacific Bell, SBC Nevada Bell and SBC SNET n. 1. The fat of a deer.

CPE - Customer Premises Equipment product portfolio. Customers now can benefit from an SBC managed service that delivers a dedicated, high-speed optical network utilizing dense wavelength division multiplexing See WDM. (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM.
DWDM - wavelength division multiplexing ) to create protocol independent high bandwidth optical connectivity.
Multi-Service Optical Networking (MON) enables customers to interconnect client data centers and business sites in a highly reliable, secure metropolitan area network. This service is also ideal for mirroring data and transmitting large quantities of information at high speeds while allowing customers uninterrupted access to their business operations.
MON is a dedicated point-to-point network solution transmitting data at speeds of up to 2.5 Gbps per wave length. It can support up to 160 Gbps of unprotected traffic or 80 Gbps of protected traffic on the fiber. This high-bandwidth optical network is enabled by DWDM, which makes it possible for many data streams to travel over the same pair of fiber by utilizing different colors of light.
MON and the Optical CPE offering support a range of transport protocols including ESCON (Enterprise Systems CONnection) An IBM S/390 fiber-optic channel that transfers 17 Mbytes/sec over distances up to 60 km depending on connection type. ESCON allows peripheral devices to be located across large campuses and metropolitan areas. , FICON (FIber CONnector) An IBM mainframe channel introduced with its G5 servers in 1998. Based on the Fibre Channel standard, it boosts the transfer rate of ESCON's half-duplex 17MB/sec to a full-duplex 100MB/sec. , ETR ETR Estimated Time of Return/Repair

The transport protocols are delivered in their native format, eliminating the need for a costly translation process to enable cross platform interoperability.
"Information is the life blood of an enterprise. To assure that none of that valuable data is lost in an outage, they must mirror the contents and computing power of their mainframes and storage area networks," said Mike Reddout, vice president, data networking, SBC. "High-bandwidth native protocol connections make that task more efficient and cost effective."
"Optical networking architectures are continuing to make tremendous strides in the metropolitan arena," said Nick Maynard, research analyst, the Yankee Group. "The flexibility and the cost efficiency of SBC's MON service addresses a critical enterprise need and will help accelerate the build out of optical technologies in the metro market."
Throughout their evolution, enterprise customers have called upon key integrators and equipment suppliers to provide the infrastructure and expertise required to support their applications. SBC has been the company of choice for many enterprise customers around the continent to provide the network transport, network integration services and equipment needed to support these applications. In collaboration with Nortel Networks, SBC is now able to provide their customers the next generation high-speed data networks that they are demanding to support their bandwidth intensive applications.
Both the SBC MON service and the Data CPE product offering utilizes the Nortel Networks OPTera Metro 5200 Multiservice Platform. The Data CPE product also incorporates the Nortel Networks OPTera Metro 3000 Next Generation SONET Platform for customers who require both optical and electrical interfaces.
