Item Description

Genuine Original Overture Networks ISG 45+ Chassis Ethernet Switch 5211-900. The Overture 45+ can attach to an existing SONET/SDH Add Drop Multiplexer (ADM), DS3 fixed wireless link, or a leased DS3 facility. Two subscriber Ethernet ports enable prioritized traffic to be fed to the network. In a hub-and-spoke configuration, several Overture 45s can feed the Overture 5100, 6000 or other aggregation switches and can be managed in-band through the DS3 connection. The Overture 45+ can also be paired back-to-back to deliver cost-effective point-to-point Ethernet and TDM interconnections. With the Overture 45+, a carrier is able to enter a single customer location and capture Ethernet service revenue with a low, first-cost solution that can be deployed today and pay for itself within a few months— without having to invest in a costly build out of the metro network. Using the Overture 45+ in conjunction with the Oveture 6000, 5100 or 6100 delivers the greatest value to the customer, as more intelligent services and management capabilities can be leveraged via hub-and-spoke configuration. For example, with a single Overture 6000 serving as the hub, up to 24 ISG 45+s can be deployed across a metropolitan area, an office park or up the risers in a multi-tenant building to deliver managed Ethernet services.
