Irvine, California-headquartered Sync Research Inc has announced the FrameNode 4200, which it claims is the industry’s first stackable Frame Relay Access Device. The company said the device is ideal for consolidating SNA, primitive protocol and local area network devices over Frame Relay at larger sites. Each unit consists of eight universal multiprotocol serial ports and an optional Ethernet or Token Ring local network interface. A port’s physical interface is determined by the attached cable adaptor and can support line speeds of up to 2.048Mbps. The 4200 Series supports the company’s new OpenStack architecture and runs its FrameNode internetworking FRAD Frame Relay Access Device software. It also supports Sync’s Conversion Node serial-to-local area network conversion software. Available this month, the 4200 will cost between $6,000 and $7,600.
