Multi-service Processor facilitates migration to IP-based networks.

Press Release Summary:

Model LCP5400 multiservice processor enables migration of time-division multiplex (TDM) equipment Internet protocol (IP) solutions. Increasing bandwidth of OEM transport line cards for wireless backhaul and media gateways, LCP5400 minimizes number of legacy TDM slots required in chassis and allows more room for IP-based cards, giving OEMs and service providers ability to increase number of SONET/SDH connections. Multiple programmable engines, Ethernet ports, and ARM11(TM) processors are included.

LSI Announces New High-Density Multiservice Processor for Wireless Networks

LCP5400 device enables migration to IP-based networks; increases bandwidth of OEM transport line cards for wireless backhaul and media gateways

MILPITAS, Calif. - LSI Corporation (NYSE: LSI) today announced a new multiservice processor that enables OEMs to reduce the physical footprint and cost of wireless backhaul, wireless controllers and media gateways. The LCP5400, which is software compatible with the existing link communication processor from LSI, allows networking OEMs to consolidate multiple line cards, reducing inventory and development costs and speeding equipment time to market.

The LCP5400 enables the migration of time-division multiplex (TDM) equipment to more cost-effective Internet protocol (IP) solutions. The increased density of the LCP5400 reduces the number of legacy TDM slots required in the chassis and allows more room for IP-based cards. As networks continue to transition to IP, this gives OEMs and service providers the opportunity to increase the number of SONET/SDH connections without increasing the numbers of boards per system. The LCP5400 allows customers to take full advantage of the least-expensive IP or TDM leased lines available.

The LCP5400 simultaneously supports multiple protocols including ATM, PWE3, HDLC and ML/MC-PPP as well as proprietary protocols. A high degree of programmability allows connections to legacy, non-standard equipment for backwards compatibility. The LCP5400 also offers the flexibility to upgrade products already deployed through non-intrusive software updates, dramatically increasing the serviceable life of boards in the field.

"The LCP5400 increases available bandwidth from the 16 E1/T1 in the Link Communication Processor to STM-4," said Shane Gunning, director, product marketing, Networking Components Division, LSI. "This allows customers to support more connections while reducing development costs by leveraging hardware and software platforms across multiple products."

With the LCP5400, a single protocol path can take full advantage of the device's bi-directional data bandwidth, or as many as three protocols can share it simultaneously. The LCP5400 includes multiple programmable engines, integrated Ethernet ports and multiple ARM11(TM) processors.
