Designed for service providers and enterprises, ™ the Larscom 6000 is the ideal end point for a wide range of high-speed services. The Larscom 6000 delivers T1/E1 bandwidth in multiples of 16 Mbps, turning a broadband pipe into a service delivery system for current and  future frame relay, ATM, and IP service offerings. It also provides integrated Service Level Agreement (SLA) management without additional hardware or monitoring/reporting systems. Tested by the Frame Relay Forum and certified fully FRF.16 compliant, the Larscom 6000 offers complete interoperability with Multilink Frame Relay (MFR)-enabled switches and CO concentrators. By using FRF.16 plus IP forwarding functions, the Larscom 6000 supports resilient high-speed customer-to-core network connections. There is no need for intermediate hardware or routers, so advanced services can be offered at the lowest total cost of operation. By combining the latest transport technologies with robust IP services, the Larscom 6000 insures maximum return on your investment.

With the Larscom 6000 deployed at the customer premises (CP), advanced network services can be provided at a low total cost of operation. Certified compliant with the Frame Relay Forum’s Multilink Frame Relay standard (FRF.16), the Larscom 6000 eliminates the need for additional equipment between the CP and the CO. The Larscom 6000's auto-configuration, bandwidth management, and traffic shaping simplify installation and maintenance. SLA statistics gathered by the Larscom 6000 are delivered in a standard format directly to the core management system.
