Woodbridge, Virginia-headquartered Dynatech Communications Inc has introduced the DynaStar 500, an integrated local and wide area network edge concentrator switch. It is said to offer managed services support for carriers and branch office networks, and supports multiservice wide area network switching and concentration, multiple local area network routing and bridging, wide area network access and local network dial-in-dial-out support. The DynaStar 500 can concentrate traffic from up to 40 ports and is based on a scalable hardware and software architecture that supports integral local network topologies and wide area services, including Ethernet, Token Ring, Frame Relay, Asynchronous Transfer Mode DS-1, X.25, ISDN, T1/E1 and leased lines in a single system, said the firm. In addition, the product is said to support concurrent routing of IP/IPX, and bridging of DECnet, Open Systems Interconnection and XNS, plus SDLC over Frame Relay. Expansion boards are also available for T1 wide area network ports, Asynchronous Transfer DS-1 with optional Digital Service Unit/Channel Service Unit, Token Ring, an additional Ethernet, and high-speed and low-speed synchronous-asynchronous ports, said Dynatech. The company addsed that mobile and remote workers can access branch office-based NetWare or Unix servers through standard dial-up, or X.25 facilities, and that it offers simplified maintenance through Simple Network Management Protocol, as well as remote configuration and software updating. DynaStar 500, with one Ethernet port, three high-speed wide area network ports supporting Frame Relay or X.25, one low-speed asynchronous port, local network bridging and routing software, and five expansion slots, is priced at $7,000. It is planned to ship this month.
