* SBC’s metro service now supports DWDM rings

SBC last week expanded its managed wavelength service with an offering that enables businesses to connect multiple locations within a metropolitan area.

The carrier’s Multi-Service Optical Networking (MON) service now supports dense wavelength division multiplexed (DWDM) rings, which enable business to connect mainframes, data centers and storage networks.

Up to now, MON, which was turned up in 2001, supported just point-to-point DWDM services between two business locations. Contracts for that service start at about $30,000 per month for 60 months.

MON supports ESCON, FICON, Fibre Channel, Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, SONET and video services at 160G bit/sec per fiber pair.

In addition to supporting connectivity between multiple locations, MON’s new ring architecture provides increased reliability and redundancy, making it applicable for disaster recovery, data mirroring and business continuity applications, SBC says.

MON is available throughout SBC’s 13-state local service territory. Both MON services are based on Nortel’s OPTera Metro 5200 Release 5.0 platform.

Pricing for the MON ring service starts at about $30,000 per month for a 5-year term, according to SBC.
