AT&T Broadband and Internet Has Chosen Shore Redundant Link Protectors...

Shore Introduces Programmable Bypass Switch Line

NASA Chooses Shore Redundant Fiber Link Protector

Long Branch,  NJ - August 6,  2002  - Shore Microsystems announced today that since November 2000, it has been supplying the SM-2512 Redundant Ethernet Link Protectors to AT&T Broadband and Internet Company. The SM-2512 has been installed in the majority of AT&T’s Head End Centers across the United States providing redundancy for their HFC (Hybrid Fiber Coaxial) Telephony Ethernet Ports. The project to date has totaled over one million dollars.

Long Branch, NJ - January 31, 2002 - Shore Microsystems today announced the release of the "24 Series" of Programmable Bypass Switches.  The Bypass Switches are designed for the purpose of maintaining connectivity and integrity within networks utilizing Transparent Network Appliances such as a cache server.  An appliance failure, which traditionally causes a network failure, can now be detected by the Series 24 Bypass Switch.  The appliance can then be "bypassed" by the Series 24 device so that normal operation of the network is restored.

The "24 Series" initially consists of two products:  the SM-2400 for 10/100BaseT and the SM-2400G for 1000BaseT (Gigabit) Ethernet.  Both products are available now in either a PCI card version or as a standalone unit for external applications.  The SM-2400 interacts with a simple watchdog process on the network appliance and in the event that the network appliance fails, the SM-2400 bypasses the failing system.  The SM-2400 can also bypass based on failure of the Ethernet links providing connections to the appliance.  The SM-2400 has been designing with Shore Microsystems' Straight Through WireTM technology.  This allows the unit to continue to provide connectivity even through a power failure event assuring reliable network operation.

Long Branch, NJ - January 14, 2002 - Shore Microsystems announced today that it has received the first order from the Kennedy Space Center (KSC), National Aeronautics and Space Administration (NASA) for SM-2501F Fiber Link Protectors. The SM-2501F provides redundancy for fiber networks upgrading to either a more fault tolerant design or, as in the case with Kennedy Space Center, augmenting the replacement of outdated Fiber Distributed Data Interface (FDDI).

The SM-2501F allows networks to create redundant connections for their "mission critical" 100BaseFX connections by allowing simultaneous connections to both a primary and backup network port from servers, routers, and other key network equipment. The SM-2501F operates by monitoring the primary link and, in the event of failure, automatically switching to the backup link.

The Fiber Link Protector is programmable with respect to switchover speed to either accelerate switchover for no data loss or delay switchover to allow for slow boot switching hubs. Kennedy Space Center achieved switchover times between 20 and 40 milliseconds in real time lab testing. The SM-2501F will also switchover when a far-end fault (FEF) occurs and is 802.3u Clause 24 Compliant. A far-end fault (sometimes referred to as Remote Fault) occurs when a receive link on the remote device fails. Far-end fault is undetectable by other redundant technology.
