SBC Communications enhanced the features and widened availability of its Multi-Service Optical Networking (MON) service, which uses DWDM to connect the data centers, mainframes and storage networks of large enterprises within a metropolitan area. SBC's MON is now offering up to 160 Gbps of capacity per fiber pair. The enhanced service also provides the ability to connect multiple locations in a metro area using a ring network configuration. Previously, the service was available as a dedicated point-to-point network solution. The enhanced MON service offering works in conjunction with a number of data transport protocols, including ESCON, FICON, ETR, ISC, Fibre Channel, Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, SONET and D1 video, all in their native format. The MON offerings are available throughout the SBC 13-state local service territory. SBC is using Nortel Networks OPTera Metro 5200 5.0 Multi-service Platform release 5.0, a DWDM system, for the service.

- SBC Communications first introduced its Multi-Service Optical Networking (MON) servince in 2001.
In October 2002, SBC Services, an affiliate of SBC Communications, signed a multiyear agreement to purchase the Nortel Networks OPTera Metro 5100 Multiservice Platform. The equipment will be used for managed wavelength services including high-speed Optical Ethernet and storage services throughout SBC's 13-state territory. A year earlier, SBC signed a contract to purchase the Nortel Networks OPTera Metro 5200 to support its Multi-Service Optical Networking (MON) service. The OPTera Metro 5100 is designed for smaller bandwidth requirements that extend wavelengths to the customer premise. The OPTera Metro 5200 is a higher scale, survivable platform for metropolitan access and interoffice applications.
