Larscom & Lucent Technologies Demonstrate Interoperability for Multilink Frame Relay Solution That Delivers Affordable, Customized Bandwidth Services Lucent to Distribute Larscom 6000 Multiservice Access Device; Solution Allows Providers to Cost-Effectively Deploy Higher Bandwidth (NxT1) Services NEWARK, Calif., Nov. 10 /PRNewswire-FirstCall/ -- Responding to the demand for more bandwidth in the enterprise market, Larscom today announced they have successfully demonstrated a Multilink Frame Relay (MFR) solution with Lucent Technologies that helps service providers deliver additional bandwidth in cost-effective increments that are easy and quick to deploy. With this solution, service providers can offer enterprises incremental bandwidth services -- such as 3 Mbps (2xT1) or 6 Mbps (4xT1) -- for a fraction of the cost of a T3 (which can run up to 12 times more than the cost of a T1 using either ATM or Frame Relay)(1). Interoperability testing was recently completed demonstrating the compatibility of the Lucent CBX 500(R) Multiservice WAN Switch with the Larscom(TM) 6000 access device for Multilink Frame Relay. The Larscom 6000 is an IP- and Frame Relay-Aware access device for the customer's premise that is compliant with the Frame Relay Forum's (FRF) FRF.12 and FRF.16 standards. Lucent's market-leading CBX 500(R) Multiservice WAN Switch helps service providers deliver profitable ATM and Frame Relay services and add IP services through cost-effective multiservice capabilities. The 5 Gbps carrier-class edge switch supports FRF.16.1 to provide robust scalability for MFR-based services. The Larscom 6000 multiservice access device and Lucent CBX 500(R) switch are now available for purchase and deployment through Lucent. "The demand for more bandwidth is being fueled by businesses that are increasingly capitalizing on high-productivity applications, customer and supplier extranets, eCommerce, large file transfers, and streaming media to improve employee productivity and maintain tight relationships with customers and suppliers," said Gurdip Jande, Vice President of Marketing at Larscom. "There is a significant untapped market for affordable Frame Relay services that offer more bandwidth than a T1, yet cost less than a T3." MFR is a standards-based frame transport protocol pioneered by the Frame Relay Forum that is designed to reduce costs by bundling inexpensive and quickly provisioned T1 circuits in incremental steps matched to enterprise bandwidth needs. Recent improvements in technology, updated specifications from the Frame Relay Forum, and the need to gain maximum return from existing network assets help make Multilink Frame Relay a compelling solution to meet growing enterprise bandwidth requirements and a potential source of new revenue for service providers.
