Intel Corporation has introduced the Intel LXT3008 Protection Interface Unit (PIU), a chip that enables telecommunications equipment manufacturers to develop more reliable line cards.
The new PIU allows an active connection on a line card to be switched from one port to another when a port failure occurs –without losing the connection. A single LXT3008 PIU with Intel’s N+1 silicon technology, can replace as many as 32 electro-mechanical relays, the solution used on most telecommunications line cards today.
This provides protection for any number of active line cards and ensures 99.9 percent service availability. The result is increased reliability and integrity of service providers’ networks.
Intel’s LXT3008 PIU Line Interface Unit (LIU) protection solution has a number of advantages over traditional electro-mechanical relays. These advantages include lower power consumption, microsecond switching speeds, minimal switching noise (the noise generated by electrical signals moving from contact to contact) and markedly lower printed circuit board space requirements.
The LXT3008 is the newest member of Intel’s family of T1/E1/J1 devices, that enable network integrity, joining the Intel LXT384 with Hitless Protection Switching (HPS) which provides 1+1 redundant back-up. Both chips were developed as part of the Intel Internet Exchange Architecture which enables rapid product development of communications silicon by telecommunications equipment manufacturers.
Key areas in which telecommunications equipment manufacturers will use the LXT3008 include such short-haul T1/E1/J1 applications as SONET/SDH add-drop multiplexers, digital access cross connect systems, digital loop carriers and access concentrators. The LXT3008 – priced at $19.80 in 1,000-piece quantities – is available now for sampling, and will be available for production in May.
